A3 Picture Frames: The Complete Guide to Choosing the Perfect Frame

A person holds a framed landscape painting of mountains, a river, and a colorful sky in a bright living room with a plant and books on the coffee table.

You’ve found the perfect piece of art, that spectacular A3 print you can’t wait to display. But now comes the part that can feel surprisingly tricky: choosing the frame. Suddenly, questions arise. What are the exact dimensions in centimetres versus inches? Will a mount make it look more professional? And how do you select a material that protects your print without overpowering the image?

Finding the perfect a3 picture frame should be a joy, not a source of stress. A frame is the essential bridge between your artwork and your décor, a piece of craftsmanship designed to elevate and preserve what’s inside. It’s the final touch that transforms a simple print into a beautiful, personal statement for your home.

Consider this your complete guide. We’re here to walk you through everything you need to know, from demystifying dimensions and materials to offering styling tips that will make your artwork truly shine. Let’s embark on this journey together and find the premium frame your art deserves.

What are the A3 Frame Dimensions? Getting the Basics Right

Embarking on your framing journey begins with a clear understanding of size. A3 is a wonderfully versatile and popular choice, striking the perfect balance for showcasing fine art prints, bold posters, and cherished photographs without overwhelming your space. Its universal appeal stems from the globally recognised ISO 216 international paper size standard, which guarantees that an A3 print will always have consistent dimensions. This standardisation removes the guesswork, ensuring that when you select an A3 piece, you know exactly what you’re working with. Getting these foundational measurements right is the first step toward finding the perfect a3 picture frame to complement your art.

To see these concepts in action and get some practical tips, this helpful video offers a great visual guide to framing.

A3 Size in Millimetres, Centimetres, and Inches

At First 4 Frames, we believe precision is the soul of craftsmanship. To ensure a perfect fit, it’s essential to know the exact dimensions of an A3 sheet. This is the size of your artwork itself, not the final frame. Being familiar with these measurements in millimetres, centimetres, and inches will give you the confidence to select the right frame every time.

Here is a quick-reference conversion guide for the A3 paper size:

  • In Millimetres (mm): 297 x 420 mm
  • In Centimetres (cm): 29.7 x 42 cm
  • In Inches (in): Approximately 11.7 x 16.5 inches

Frame Size vs. Aperture Size: Understanding Mounts

This is a crucial distinction that elevates a simple framed picture into a professionally presented piece of art. When you see a product described as an “A3 frame,” it’s vital to clarify what this means. It can refer to a frame with internal dimensions of exactly 29.7 x 42 cm, designed for your artwork to fit snugly from edge to edge. This style offers a clean, modern, and direct presentation.

However, for a classic, gallery-style look, the term often refers to a larger frame that incorporates a mount (also known as a passe-partout or window mount). This is a high-quality card border that sits between the artwork and the frame. The ‘aperture’, or opening, of this mount is cut precisely to display your A3 print. Using a mount is not just about aesthetics; it also protects your art by creating a small air gap between the print and the glazing. For instance, a common choice is a 40 x 50 cm frame with a mount whose aperture is cut for A3. This added border draws the eye inward, enhances the artwork’s presence, and acts as the perfect bridge between the art and its surroundings.

Choosing the Best Material for Your A3 Picture Frame

The material of your frame does more than just hold the glass; it’s the bridge between your artwork and your room’s decor. The right choice enhances the art, protects it for years, and reflects your personal style. When selecting an a3 picture frame, the material is one of the most important decisions you’ll make. Let’s explore the most popular options: classic wood, sleek metal, and versatile composite materials.

Solid Wood Frames: Classic, Warm, and Timeless

For a touch of natural beauty and a truly premium feel, nothing compares to solid wood. Crafted with care, these frames offer exceptional durability and a timeless appeal. Available in a variety of beautiful finishes, from the rich tones of oak and walnut to classic painted options, they bring warmth and sophistication to any space. A solid wood frame is the perfect partner for traditional art, fine art prints, and stunning nature photography, celebrating the quality of both the image and the craftsmanship.

Metal & Aluminium Frames: Modern, Sleek, and Minimalist

If your style leans towards the contemporary, a metal or aluminium frame is an excellent choice. Celebrated for their clean lines and minimalist aesthetic, these frames often feature a very thin profile, ensuring the focus remains squarely on your artwork. They are incredibly durable yet surprisingly lightweight, making them easy to hang. Available in popular finishes like matte black, polished silver, and elegant gold, they are ideal for framing posters, graphic prints, and professional certificates.

Composite (Polcore) Frames: Versatile and Budget-Friendly

Offering fantastic value without compromising on style, composite frames are a brilliant and popular choice. Often made from Polcore, an eco-friendly material created from recycled polystyrene, these frames come in a vast array of styles. They can expertly mimic the grain of real wood or offer a perfectly smooth, modern finish in any colour imaginable. While they may not have the same heirloom quality as solid wood, a composite a3 picture frame is a superb, cost-effective solution for decorative prints and posters.

To help you decide, consider the essence of your piece and your decor:

  • For warmth and tradition: Choose Solid Wood to add a natural, premium feel.
  • For a sharp, modern statement: Choose Metal for its clean, minimalist lines.
  • For versatility and value: Choose Composite for an endless choice of styles at a great price.

How to Select the Perfect Style and Colour

Choosing the perfect frame is an art in itself. Think of your frame as the bridge that connects your beautiful artwork to your room’s decor, creating a seamless and harmonious display. The right style and colour will enhance the piece without overpowering it, allowing the art to take centre stage while the frame does the important work of integrating it into your space. From sleek, simple profiles to ornate, traditional designs, the choice you make will define the final look.

Matching the Frame to the Artwork

A simple rule to follow is that the art is the hero, and the frame is its dedicated support. The goal is to complement, not compete. Minimalist prints or modern photography often look spectacular in a simple, thin frame that doesn’t distract from the clean lines. In contrast, classical art or a piece with intricate detail can be beautifully balanced by a more substantial or ornate frame. For a truly professional touch, select a frame colour that picks up on a subtle accent colour within the artwork itself.

Coordinating the Frame with Your Room Decor

A well-chosen frame should feel like a natural part of your room. Take a moment to consider the existing finishes and furniture. Are your door handles brass? Is your furniture made of light oak? Matching your frame to these elements creates a cohesive feel. For maximum versatility, a black or white a3 picture frame is a timeless choice that fits almost any interior style, from contemporary to traditional.

  • Wood Frames: Natural wood finishes, like oak or walnut, introduce warmth and texture, perfect for neutral, rustic, or Scandinavian-inspired spaces.
  • Black or White Frames: The ultimate chameleons, these frames provide a clean, classic border that works with any colour scheme.
  • Metal Frames: Finishes like silver, gold, or brass add a touch of elegance and complement modern, industrial, or glamorous interiors.

When to Use a Mount to Elevate Your A3 Print

A mount, or mat, is the paper-board border that sits between the art and the frame. It serves two key purposes. Aesthetically, it provides visual ‘breathing room’ around your print, drawing the eye inward. Functionally, it separates the artwork from the glazing, protecting it from potential damage caused by condensation. A crisp white mount is a classic choice that lends any print a sophisticated, gallery-quality finish. Need help creating the perfect combination? Explore our bespoke framing options.

Glazing and Backing: Protecting Your A3 Print for Years

When you invest in a beautiful A3 print, the frame does more than just complement the artwork; it serves as its primary protector. The two most critical components for preservation are the glazing (the clear front sheet) and the backing board. While it can be tempting to opt for a budget frame, cheaper materials often contain acids and impurities that can cause irreversible damage to your art over time, from fading to yellowing.

Understanding these components is the key to ensuring your cherished print remains as vibrant as the day you bought it.

Choosing Your Glazing: Glass vs. Acrylic

The glazing is the clear barrier between your print and the world. The choice you make here impacts not only protection but also the final look, weight, and safety of your framed piece. Here’s a simple breakdown:

  • Standard Glass: Offers perfect, crystal-clear clarity and a satisfying weight that speaks to its quality. It’s scratch-resistant and easy to clean, making it a timeless choice for most settings.
  • Acrylic (Perspex): A lightweight and shatter-resistant alternative. This makes it the perfect option for an a3 picture frame that needs to be shipped, hung in a child’s room, or placed in a high-traffic area. Modern, high-quality acrylic offers excellent clarity with added safety.

For truly valuable or sentimental pieces, consider upgrading to UV-protective glazing. Available in both glass and acrylic, this special coating blocks up to 99% of harmful ultraviolet rays, the primary cause of fading. It’s a small investment for priceless peace of mind.

The Importance of an Acid-Free Backing Board

What rests behind your print is just as important as what’s in front. The backing board provides structural support, but its material composition is crucial. Many off-the-shelf frames use standard cardboard or MDF, which are full of acids. Over years, these acids migrate into your artwork, causing a damaging process called ‘acid burn’ that leads to permanent yellowing and brittleness.

A professional, high-quality a3 picture frame will always use an acid-free or conservation-grade backing board. This archival-quality material is chemically stable and acts as a protective barrier, ensuring your print remains pristine for decades. It is a non-negotiable feature for anyone serious about preserving their art. At First 4 Frames, all our frames are built with premium, acid-free materials to guarantee the longevity of your artwork.

Creative Ways to Display A3 Frames in Your Home

The beauty of the A3 size lies in its remarkable versatility. It’s large enough to make a significant visual impact on its own, yet compact enough to fit gracefully into almost any space, from a cosy reading nook to a spacious hallway. Moving beyond a single, isolated picture can transform your walls into a curated display of your personal style. Here are a few professional techniques to help you arrange your art with confidence and flair.

Create a Symmetrical Pair or Triptych

For a look that is both dramatic and perfectly ordered, consider hanging two or three matching A3 frames side-by-side. This approach works beautifully above a key piece of furniture like a sofa, bed, or console table, creating a strong horizontal line that draws the eye. Use this format to showcase a series of related art prints—such as botanical illustrations or architectural sketches—or even a single panoramic photograph split across the frames. The result is a high-impact, cohesive display that feels intentional and professionally styled.

Use A3 as the Anchor in a Gallery Wall

A sprawling gallery wall can quickly feel cluttered without a clear focal point. An a3 picture frame is the perfect piece to provide structure and prevent visual chaos. Start by placing your largest piece, the A3 frame, in a central or slightly off-centre position. From there, you can build outwards, arranging smaller frames (like A4 and A5), postcards, and other treasures around it. This creates a visual anchor, giving the entire arrangement a sense of purpose and balance that is pleasing to the eye.

Stylish Framing for Certificates and Diplomas

Your hard-earned achievements deserve more than a standard, off-the-shelf frame. Elevate your certificates, diplomas, and awards by presenting them with the sophistication they warrant. An A3 frame, complete with a custom-cut mount, transforms a simple document into a statement piece for your home office or study. Choose a premium frame style—a warm oak to match your desk or a sleek black for a modern aesthetic—to create a truly integrated and professional look.

Frequently Asked Questions About A3 Picture Frames

Can I put an A4 print in an A3 frame?

Yes, absolutely. An A3 frame is the perfect choice for showcasing an A4 print with a beautiful, professional-looking mount. The mount, or passe-partout, creates a border that draws the eye towards the artwork and prevents it from touching the glass. This is a classic gallery technique that gives your smaller artwork more presence and a truly spectacular finish on your wall, protecting it while enhancing its visual appeal.

What is the difference between an A3 poster frame and a picture frame?

While the terms are often used interchangeably, the main difference lies in the craftsmanship and materials. Poster frames are typically lighter, often made with plastic or MDF and perspex, designed for more temporary displays. A premium A3 picture frame is built for longevity, crafted from quality materials like solid wood with proper glass glazing. It provides a sturdier, more elegant home designed to protect and enhance fine art for years to come.

How do I measure my artwork correctly for an A3 frame?

For a perfect, hassle-free fit, precision is key. Lay your artwork on a clean, flat surface and use a steel ruler or firm tape measure to find its exact height and width. An official A3 paper size is 297 x 420mm (29.7 x 42cm). If your art matches these dimensions, it will fit snugly inside the frame without a mount. For any other size, measure carefully to ensure you choose the correct bespoke mount aperture.

Are black or white A3 frames more popular?

Both black and white frames are timelessly popular, each offering a distinct aesthetic. A black frame creates a bold, classic contrast that makes the colours within your artwork truly pop. A white frame provides a clean, contemporary feel, perfect for minimalist interiors or creating an airy, bright look. The best choice is the one that acts as the perfect bridge between your artwork and your room’s décor, so consider which will best complement your personal style.

Is it better to buy an A3 frame with or without a mount included?

This depends on the final look you wish to achieve. If your artwork is A3 size and you want a full-bleed, edge-to-edge presentation, a frame without a mount is ideal. However, including a mount adds a layer of professional sophistication, creates protective space between the art and the glass, and allows you to elegantly display a smaller piece within the frame. For a truly polished, gallery-worthy display, we almost always recommend using a mount.

How can I hang a heavy wooden A3 frame safely?

To hang a heavier wooden frame securely, we advise against using a single nail. The safest method is to fix two D-rings to the back of the frame, about one-third of the way down from the top on each side. Then, install two corresponding picture hooks or screws with appropriate wall plugs into your wall, making sure they are perfectly level. This two-point hanging system distributes the weight evenly and ensures your beautiful frame remains stable and secure.

A3 Photo Frames: The Complete Guide to Choosing the Perfect Frame

A person places a wooden frame over a landscape photo on a table, with two empty frames—one black, one white—resting upright nearby against a beige wall.

You’ve found the perfect piece of art—a stunning print, a cherished photograph, or a hard-earned certificate that deserves to be seen. But now comes the crucial next step: finding the perfect a3 photo frame to do it justice. This is where the questions often begin. Should you add a mount for that professional gallery look? Will a warm, classic oak or a sleek, modern metal best complement your interior? It’s easy to feel uncertain, worried that a poor choice could detract from the very piece you want to celebrate.

Embark on your framing journey with confidence. This guide is designed to be your trusted partner, demystifying every aspect of choosing an A3 frame. We will explore everything from precise dimensions and the transformative power of a mount, to selecting premium materials that act as the perfect bridge between your artwork and your décor. Discover how to protect and enhance your art, ensuring it becomes a spectacular focal point in your home for years to come.

What is an A3 Photo Frame? Dimensions & Common Uses Explained

Choosing the perfect frame begins with understanding the right size for your art. An a3 photo frame is designed to house artwork or photographs measuring A3 size, a popular and versatile choice for making a statement without overwhelming your space. It strikes a beautiful balance, offering significant visual impact while fitting comfortably on most walls, making it a favourite for both homes and professional settings.

To help you visualise the scale and potential of this size, here is a helpful overview:

A3 Frame Dimensions: Getting It Right

Precision is key in craftsmanship. The A3 size is part of the internationally recognised ISO 216 standard, which ensures consistency worldwide. These dimensions refer to the size of the paper or print the frame is built to hold:

  • In millimetres: 297 x 420 mm
  • In centimetres: 29.7 x 42 cm
  • In inches: Approximately 11.7 x 16.5 inches

It’s important to remember that these measurements are for the artwork itself. The visible area, or ‘aperture’, may be slightly smaller due to the frame’s lip holding the artwork in place. The external dimensions of the frame will be larger, depending on the width of the bespoke moulding you choose.

Popular Uses for A3 Picture Frames

The A3 size is wonderfully adaptable, making it a superb choice for a variety of displays. Its generous proportions provide the perfect canvas for showcasing meaningful pieces with professional flair. Common uses include:

  • Fine Art & Posters: Displaying beautiful giclée prints or favourite posters, creating a spectacular focal point in a living room or hallway.
  • Professional Certificates: Framing diplomas, awards, and accreditations for a polished and impressive office display.
  • Large-Format Photography: Giving treasured family portraits or stunning landscape shots the presence they deserve.
  • Children’s Artwork: Elevating a child’s creative masterpieces into cherished pieces of bespoke art for your home.

Choosing Your Material: A Guide to A3 Frame Styles & Durability

The material of your frame is more than just a border; it’s the bridge between your room’s décor and the artwork itself. It performs the heavy lifting, setting the tone and ensuring your piece is protected for years to come. Choosing the right material is key to creating a spectacular display, influencing both the aesthetic feel and the long-term durability of your chosen a3 photo frame.

Classic Wood A3 Frames

For a touch of natural warmth and timeless elegance, nothing compares to wood. A wooden a3 photo frame is exceptionally versatile, seamlessly fitting into traditional, rustic, and even minimalist Scandinavian interiors. We source premium woods like solid oak, celebrated for its beautiful grain and texture, and versatile pine, which can be finished to suit any style. Choose from a natural finish to showcase the wood itself, a rich stain for a classic look, or a painted finish in black or white for a clean, modern edge. Wood is the perfect partner for fine art prints, treasured family photographs, and serene nature photography.

Modern Metal A3 Frames

If your style leans towards the contemporary, a metal frame is an impeccable choice. Sleek aluminium frames offer a clean, minimalist aesthetic that is perfect for modern homes, professional office spaces, and industrial-inspired décor. Their characteristically slim profiles ensure that the focus remains entirely on the artwork, providing a sharp, unobtrusive border. This modern simplicity makes them an excellent choice for showcasing bold posters, crisp graphic art, and important certificates where the content needs to command attention.

Glazing Options: Acrylic vs. Glass

The ‘glass’ that protects your artwork, known as glazing, is a crucial component for both clarity and preservation. The two primary options each have distinct benefits:

  • Standard Glass: Offers exceptional clarity and a traditional, high-quality feel. However, it is heavier and can be prone to breakage.
  • Acrylic (Perspex): A lightweight and shatter-resistant alternative that is often safer for shipping and high-traffic areas. Premium acrylic offers clarity comparable to glass.

For irreplaceable or valuable prints, we strongly recommend opting for glazing with UV protection. This specialist coating filters out damaging ultraviolet light, preventing fading and preserving the vibrancy of your art for a lifetime. For a deeper understanding of how different components work together, the Image Permanence Institute provides a comprehensive guide to preservation framing materials.

To Mount or Not to Mount? Elevating Your A3 Artwork

When you choose a frame, one of the most impactful decisions you can make is whether to include a picture mount. A mount, sometimes called a mat, is the elegant cardboard border that sits between your artwork and the frame itself. It’s far more than just a decorative touch; it serves a dual purpose that is crucial for both the presentation and preservation of your piece.

First, a mount provides essential protection. By creating a small air gap, it prevents your print from touching the glazing. This is vital for avoiding potential damage from condensation, mould, or the photograph permanently sticking to the glass over time. Secondly, it offers visual ‘breathing room’. This clean space separates the art from the frame, eliminating distractions and drawing the viewer’s eye directly to the image. This simple addition is the secret to achieving a professional, gallery-quality look in your own home.

When to Use a Mount with Your A3 Print

A mount is a versatile tool, but it truly shines in specific situations. Consider adding a mount to your a3 photo frame if you are displaying:

  • Fine Art Prints and Photographs: A mount is highly recommended to protect the print and enhance its artistic merit.
  • Certificates and Awards: It lends an air of sophistication and importance to official documents.
  • Smaller Images: A mount is the perfect way to elegantly fit a smaller picture (like an A4 print) into a larger A3 frame, creating a beautiful, balanced display.

Conversely, for full-bleed posters or bold graphic prints where you want the image to have a direct, punchy impact right to the edge, it’s often best to frame without a mount.

Choosing the Right Mount Colour and Size

The colour and size of your mount act as the bridge between your art and your decor. While bespoke options are endless, a few classic choices work beautifully for most pieces:

  • Off-White or Cream: These are timeless, safe choices that complement both traditional and contemporary artwork without competing with it.
  • Crisp White: For a clean, modern, and high-contrast look, a pure white mount is an excellent option, especially for black and white photography.
  • Darker Mounts: A black or charcoal mount can create a dramatic, moody effect, making the colours in your artwork appear more vibrant.

As a rule of thumb, standard mount borders are typically between 50mm and 80mm wide, providing a substantial and well-proportioned border for your A3 print.

Styling and Hanging Your A3 Frame Like a Pro

You’ve chosen the perfect print and a beautiful, bespoke frame to match. Now for the exciting part: bringing it all together in your home. A well-placed frame does more than just hold a picture; it acts as a bridge between your artwork and your room’s decor, creating a focal point that pulls the entire space together. An a3 photo frame is a wonderfully versatile size, large enough to make a statement yet adaptable enough to suit any room.

With a little planning, you can display your new art with the confidence of a professional curator. Here are our expert tips for styling and hanging your frame for maximum impact.

Matching Frames to Your Interior Style

The key to a cohesive look is choosing a frame that complements your existing decor. Think of the frame as the final piece of the puzzle. Our premium frames are designed to suit a range of popular aesthetics:

  • Minimalist: For a clean, contemporary feel, opt for a thin frame in black, white, or brushed silver. The simplicity of the frame allows the artwork to take centre stage.
  • Traditional: Warm, natural oak or a more ornate wooden frame adds a touch of classic elegance. These styles work beautifully in period homes or rooms with traditional furnishings.
  • Bohemian/Eclectic: Don’t be afraid to mix and match! A collection of different frame styles, colours, and finishes creates a relaxed, personal, and artfully curated vibe.
  • Industrial: A simple, bold black metal frame offers a strong, graphic look that pairs perfectly with exposed brick, concrete, and raw materials.

Creating a Breathtaking Gallery Wall

The A3 size is the perfect anchor for a stunning gallery wall. It provides a strong central element to build around, ensuring your display feels balanced rather than cluttered. Whether you’re filling a large empty wall or creating a feature above a sofa, here are a few ideas:

  • The Hero Piece: Use a single a3 photo frame as the focal point of your collection. Surround it with a mix of smaller A4, A5, and square frames to create a dynamic, asymmetrical layout.
  • Symmetrical Grid: For a powerful, high-impact statement, hang a grid of three or four identical A3 frames. This works especially well with a series of related prints, like architectural drawings or botanical illustrations.
  • Pro Tip: Before you pick up a hammer, map out your arrangement on the floor. Cut paper templates to the size of your frames and tape them to the wall to perfect your spacing and layout.

Beyond Off-the-Shelf: When to Choose a Bespoke A3 Frame

Ready-made frames offer a quick and convenient solution, but for artwork or photographs that truly matter, they often fall short. Mass-produced frames can have limitations in material quality, protective properties, and the overall finish, which can detract from the beauty of your piece. Bespoke framing is the ultimate step up, transforming a simple picture into a beautifully presented and protected work of art.

While ‘A3’ is a standard paper size, your artwork is anything but standard. Opting for a custom-made a3 photo frame is an investment in preserving your memories and showcasing your art with the professional craftsmanship it deserves. It’s about creating a perfect partnership between the image and its enclosure, ensuring it captivates attention for years to come.

Frequently Asked Questions

What are the exact dimensions of an A3 photo frame in cm and inches?

An A3 photo frame is designed to hold artwork that is 29.7 x 42 cm, or 11.7 x 16.5 inches. These are the internal dimensions of the frame, ensuring your A3 print fits perfectly. The external, overall dimensions of the frame will be larger and vary depending on the width of the beautiful frame moulding you choose. Always check the artwork size specification when purchasing to guarantee a perfect fit for your piece.

Will my A3 size paper fit perfectly into a standard A3 frame?

Yes, absolutely. A standard A3 frame is crafted with precise internal measurements to house an A3 print snugly and securely. This ensures a professional, gap-free presentation that lets your artwork shine. When you choose a high-quality a3 photo frame, you can be confident that it has been made to the exact specifications required to display your A3 document or art print perfectly, right to the edge.

Can I put a smaller photo, like an A4 print, into an A3 frame?

Certainly! Using a smaller print in a larger frame is a classic and highly effective display technique. By placing a picture mount (a cardboard border) inside the A3 frame, you can elegantly showcase an A4 print. This creates a beautiful visual space around the artwork, drawing the eye to the image and giving it a premium, gallery-style appearance that truly elevates the piece within your space.

What is the difference between a picture frame and a poster frame?

The primary difference lies in the quality of craftsmanship and materials. A picture frame is typically built for longevity, using premium materials like solid wood and high-quality glass or acrylic glazing to protect and enhance fine art. Poster frames are often more lightweight and budget-conscious, sometimes using plastic or MDF. They are perfectly suitable for prints where archival protection is less of a priority, while a picture frame is an investment in preserving your art.

How do I clean the acrylic or glass on my A3 frame without scratching it?

For beautiful, clear results, always use a soft, clean microfibre cloth to gently wipe away dust. For more stubborn marks like fingerprints, lightly dampen the cloth with water. It is crucial to avoid using paper towels or abrasive fabrics, as these can cause fine scratches. We also advise against using harsh, ammonia-based chemical cleaners, which can damage the surface of high-quality acrylic glazing over time.

Is it better to choose an A3 frame with or without a mount?

This is a wonderful creative choice that depends on your desired aesthetic. Framing without a mount creates a bold, ‘full-bleed’ look where your artwork fills the entire frame. Including a mount provides a classic, sophisticated border that draws the viewer’s eye inward. A mount also serves a practical purpose, separating your artwork from the glazing to aid in its preservation. The perfect choice is the one that best complements your art and your decor.

A3 Frames: The Complete Guide to Dimensions, Styles, and Uses

There’s a special kind of magic in finding the perfect piece of art. But turning that beautiful A3 print into a spectacular wall feature can feel surprisingly complex. Questions start to surface: What are the exact A3 dimensions in centimetres? Will it need a mount? And how do you choose a frame that elevates your art rather than making it look cheap? It can feel like a daunting task, leaving you worried about making the wrong choice for your cherished print.

Fear not. Choosing the right frame is an art in itself—it’s the bridge between your artwork and your décor. That’s why we’ve created this complete guide to a3 frames. We believe in making professional framing simple and accessible. In this guide, we will demystify everything from precise measurements and the role of a mount, to selecting a premium style that truly honours the piece within. Prepare to move from uncertainty to inspiration, ready to confidently select a beautiful frame that provides the perfect finishing touch for your home.

What is an A3 Frame? Understanding the Standard Dimensions

When choosing the perfect frame, understanding the size is the first step on your creative journey. The A3 size is one of the most popular and versatile choices for displaying everything from fine art prints to treasured photographs. As part of the globally recognised ISO 216 series, its Standard Dimensions make it a familiar and accessible option. It strikes a beautiful balance—large enough to make a statement on its own, yet modest enough to work splendidly as part of a gallery wall.

It’s important to remember that when we talk about an A3 frame, we are referring to the size of the artwork, poster, or photo it is designed to hold. The outer dimensions of the frame itself will be larger, depending on the width of the moulding you select. This versatile size is perfect for showcasing art in either a vertical (portrait) or horizontal (landscape) orientation, giving you complete creative control.

To see how these dimensions translate into a finished piece, the video below provides a fantastic hands-on look:

A3 Frame Dimensions in Detail

For perfect clarity when measuring your artwork, here are the exact dimensions of an A3 print. Ensuring your piece matches these measurements guarantees a flawless fit within any standard A3 frame.

  • Millimetres: 297 x 420 mm
  • Centimetres: 29.7 x 42 cm
  • Inches: 11.7 x 16.5 inches

The Role of a Mount: Enhancing Your A3 Artwork

A picture mount (also known as a mat or passe-partout) is the elegant cardboard border that sits between your artwork and the frame. It serves a dual purpose: it creates a professional visual separation that draws the eye inward and prevents your print from touching the glass, protecting it over time. Using a mount is a hallmark of premium, bespoke framing. For instance, our a3 frames can be beautifully paired with a mount to showcase a smaller A4 print, instantly elevating it with a sophisticated, gallery-quality finish that truly honours the art within.

The Best Uses for A3 Picture Frames in Your Home or Office

Once you understand the dimensions, the real creative journey begins. The A3 size (297 x 420 mm) hits a perfect sweet spot—it’s substantial enough to make a statement yet versatile enough to fit beautifully into any room, from a bustling office to a tranquil living space. Its adaptability is its greatest strength, offering a spectacular canvas for your most cherished memories, art, and achievements. Let’s explore how you can use a3 frames to elevate your décor.

Displaying Art Prints and Posters

The A3 format is the classic choice for artists and designers for good reason. It’s the perfect size for displaying concert posters, limited edition art prints, and bold graphic designs. An A3 frame allows the artwork’s finer details to shine without overwhelming your wall. Whether you’re showcasing a single, powerful statement piece above a desk or arranging a symmetrical series of prints along a hallway, this size provides the ideal balance and impact.

Framing Professional Certificates and Diplomas

Your academic degrees, professional awards, and certificates represent significant milestones. An A3 frame offers an elegant and professional way to display these important documents, protecting them for years to come. A premium frame does more than just showcase your hard-earned achievements; it preserves them. Using archival-quality materials is crucial, because as preservation experts advise, Quality Matters when protecting important documents from environmental damage. We recommend simple, classic styles like a slim black or natural oak frame to lend a timeless, distinguished look.

Creating a Striking Gallery Wall

A gallery wall is a beautiful way to tell a personal story, and a3 frames often play a leading role. Use them as the ‘hero’ pieces to anchor your layout, building a collection of smaller A4 and A5 frames around them for a dynamic, eclectic feel. Alternatively, for a clean and contemporary aesthetic, a symmetrical grid of identical A3 frames creates a powerful, organised display. This approach is perfect for a themed collection of photography or a series of matching art prints.

How to Choose the Perfect A3 Frame Style and Material

Selecting the perfect frame is about more than just protecting your print; it’s about creating a beautiful bridge between your artwork and your room’s decor. For A3 prints, a versatile size defined by the ISO 216 international standard, the right frame enhances the art and harmonises with your space. Think of the frame as the final, crucial touch that pulls everything together. Our passion is helping you find that perfect match, so here are a few simple tips to guide your decision.

Classic Wooden Frames: Timeless and Versatile

Wooden a3 frames bring a natural warmth and classic appeal that suits almost any interior. Crafted from premium, sustainable wood, they add a touch of timeless craftsmanship. Each finish offers a different personality:

  • Oak Frames: The gentle, warm tones of natural oak are perfect for bringing a touch of nature indoors. They beautifully complement traditional, rustic, or bohemian decor.
  • Black Frames: A classic for a reason. Black provides a bold, modern contrast that makes the colours in your artwork truly pop. It’s a spectacular choice for creating a focal point.
  • White Frames: For a clean, minimalist aesthetic, a white frame is unbeatable. It offers a fresh, airy feel that works wonderfully in Scandinavian-inspired or contemporary spaces.

Modern Metal Frames: Sleek and Contemporary

For a clean, contemporary edge, metal is an excellent choice. Aluminium frames typically have a very thin, elegant profile, ensuring the focus remains squarely on your artwork. This minimalist style is ideal for:

  • Photography and posters
  • Architectural prints and line drawings
  • Modern and industrial-style interiors

Available in various finishes like matte black, brushed silver, or subtle gold, metal frames offer a sophisticated and durable way to display your favourite pieces.

Matching Frame to Artwork: Simple Rules to Follow

Feeling unsure? Follow these simple principles to find the perfect pairing every time:

  • Complement the Style: Match the frame to the artwork’s era or mood. A modern abstract print shines in a sleek metal frame, while a classic watercolour feels at home in oak.
  • Balance the Composition: If your artwork is busy and vibrant, choose a simple, understated frame that won’t compete for attention.
  • Consider the Colour Palette: Look at the dominant colours in both the art and the room where it will hang. Choose a frame that either picks up on a subtle accent colour or provides a complementary contrast.

Ultimately, the goal is to select a frame that makes you fall in love with your artwork all over again. Ready to find your perfect match? Explore our curated collection of beautiful frames.

Quality Matters: What to Look for in a Well-Made A3 Frame

An A3 frame does more than just hang your picture on the wall; it acts as the bridge between your art and your room, protecting and enhancing the piece within. While a low price tag can be tempting, investing in a well-made frame ensures your artwork remains beautiful for years to come. Understanding the components of quality craftsmanship empowers you to choose wisely, turning a simple print into a lasting display.

The Moulding: Solid Wood vs. MDF

The moulding is the main structure of the frame, and its material is a key indicator of quality. Mass-produced frames often use MDF (Medium-Density Fibreboard) or Polcore, which are budget-friendly options. However, for superior durability and a truly premium feel, nothing compares to solid wood. Each wooden frame boasts a unique grain, offering a natural warmth and character that synthetic materials simply cannot replicate. It’s an investment in strength and timeless style.

Glazing: Protecting Your Print with Glass or Acrylic

Glazing is the clear, protective layer that shields your artwork from dust, moisture, and fading. Your main choices are:

  • Glass: Offers exceptional clarity and a traditional, weighty feel. It’s scratch-resistant and perfect for pieces that won’t be moved often.
  • Acrylic (Perspex): A lighter and shatter-resistant alternative, making it safer for high-traffic areas or children’s rooms. High-quality acrylic can also offer superior UV protection to prevent your print’s colours from fading over time.

Ready-Made vs. Bespoke Framing

Ready-made A3 frames are a convenient and cost-effective solution for standard-sized prints and posters. They offer a quick way to get your art on the wall. However, for a truly perfect finish or to protect a valuable piece of fine art, bespoke framing is the ultimate choice. A custom-made frame is crafted with higher-quality materials and precision-cut to fit your artwork exactly, eliminating unsightly gaps and ensuring archival-level protection. For a piece you truly treasure, a bespoke frame is an investment in its future. Get a quote for a custom A3 frame from our experts.

As we’ve explored, the perfect frame is more than just a border; it’s the bridge between your artwork and your decor.

The key is that quality craftsmanship makes all the difference, ensuring your cherished prints and photographs are beautifully preserved for years to come.

Frequently Asked Questions About A3 Frames

What are the exact dimensions of an A3 frame in cm and inches?

An A3 frame is crafted to perfectly house an A3 print, which measures exactly 29.7 x 42 cm or 11.7 x 16.5 inches. It’s important to note these are the internal dimensions for the artwork itself. The frame’s external size will be slightly larger, depending on the width of the beautiful moulding you select. Always measure your artwork first to ensure a professional, seamless fit for your treasured piece before purchasing.

Can I put an A4 picture into an A3 frame?

Absolutely! Placing a smaller A4 picture (21 x 29.7 cm) inside a larger A3 frame is a spectacular way to achieve a professional, gallery-style presentation. This is done by using a picture mount, which creates a crisp, clean border around your artwork. This technique gives the piece space to breathe, draws the eye inward, and adds a touch of bespoke elegance to your wall display, truly elevating the final look.

Is A3 a good size for framing a photograph?

Yes, A3 is a fantastic and highly versatile size for framing photographs. It’s large enough to make a significant impact and showcase the fine details of your image, yet not so large that it overwhelms a room. This size works beautifully as a standalone feature piece or as the centrepiece of a growing gallery wall. Whether it’s a family portrait or a stunning landscape, an A3 frame provides the perfect canvas to display your memories.

What is a picture mount and do I need one for my A3 frame?

A picture mount is a high-quality cardboard border that sits between your artwork and the frame’s glass. It serves two key purposes: it creates a visual separation that enhances the artwork, and it protects your print by preventing it from touching the glass. While you don’t need a mount if your artwork is already A3 size, we highly recommend one for adding a premium, professional finish or for framing smaller images within your A3 frame.

How do I hang an A3 frame securely on the wall?

For most A3 frames, a single, correctly installed picture hook is sufficient for plasterboard walls. Always check that the hook is rated to hold at least double the weight of your frame for safety. Use a spirit level for perfect alignment. For heavier frames or solid masonry walls, we recommend using a wall plug and screw for a more robust and secure fitting, ensuring your beautiful artwork remains perfectly displayed for years to come.

Which is bigger, an A3 frame or an A2 frame?

An A2 frame is bigger than an A3 frame. The ‘A’ paper sizing system can seem counter-intuitive: as the number gets smaller, the paper size gets larger. An A2 sheet of paper (42 x 59.4 cm) is exactly double the size of an A3 sheet. Consequently, an A2 frame is designed for a much larger, statement piece of art, while an A3 frame offers a more adaptable and popular size for most homes.
