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 Frame Size: The Complete Guide to Dimensions & Uses

A smiling man wearing an apron holds a framed landscape photograph of a lake and hills in a well-lit workshop, with framing tools and frame samples visible in the background.

You’ve found a beautiful piece of A3 art, a spectacular photograph, or a poster that speaks to you. Now comes the crucial final step: finding its perfect home on your wall. But navigating the world of the a3 frame size can feel surprisingly complex. Do you measure in centimetres or inches? Will a mount enhance the image or overwhelm it? Choosing the right frame is an act of craftsmanship, and it’s easy to feel lost in the details when you want everything to be just right.

This guide is here to be your trusted professional partner. We will demystify the exact A3 dimensions in millimetres, centimetres, and inches, ensuring you can buy online or in-store with complete confidence. We’ll explore how to select the ideal style and material to complement your artwork, and help you decide if a mount will elevate your piece from lovely to truly stunning. Let’s find the perfect frame to act as the bridge between your art and your room, making your piece shine.

What Exactly is A3 Frame Size? The Essential Dimensions

Choosing the perfect frame begins with understanding its size. Put simply, an A3 frame is expertly crafted to hold a piece of A3 paper or a print of the same dimensions. This size is defined by the globally recognised ISO 216 international paper size standard, ensuring consistency whether you’re framing a professional photograph, a fine art print, or a treasured poster.

To help you visualise it, an A3 sheet is exactly twice the size of a standard A4 piece of office paper, making it a popular and impactful choice for wall art without overwhelming a room.

For a practical look at how to handle and place artwork into a frame, this video offers an excellent tutorial:

A3 Frame Dimensions in cm, mm, and inches

To ensure you have the precise measurements for your artwork, it’s helpful to know the dimensions in various units. An A3 print measures:

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

These are the exact dimensions your print should be to fit snugly and professionally within an A3 frame.

Artwork Size vs. Frame Size: A Crucial Distinction

One of the most important details to understand is that when you purchase an ‘A3 frame’, the measurement refers to the internal aperture—the ‘window’ that your A3 artwork will fit into perfectly. The overall external dimensions will always be larger, depending on the width of the frame’s border, often called the ‘moulding’ or ‘profile’. This is a crucial detail to consider when planning your gallery wall to ensure a perfect fit in your chosen space.

Portrait vs. Landscape Orientation for A3 Frames

The versatile a3 frame size is beautifully suited for displaying artwork in both portrait (vertical) and landscape (horizontal) orientations. Most high-quality frames, including those we craft, are supplied with flexible fittings on the backboard, allowing you to hang them either way with ease. We always recommend checking the orientation of your chosen artwork first to help you envision its perfect spot on your wall before making a final decision.

Common Uses for A3 Frames: What Fits Perfectly?

The A3 frame size is often considered the “Goldilocks” of framing—not too big, not too small, but just right. It’s a wonderfully versatile and popular mid-size option that makes a beautiful statement without overwhelming your space. Measuring 29.7 x 42 cm, it strikes the perfect balance between offering enough scale for visual impact and allowing the finer details of the artwork to be appreciated. For those interested in the precise standards behind these measurements, the University of Cambridge offers a technical overview of the A3 frame dimensions and the ISO 216 paper system.

Displaying Art Prints and Posters

A3 is the ideal canvas for the affordable art prints, limited edition graphics, and concert posters you love to collect. It’s large enough that the artwork commands attention and its details can be enjoyed from across the room. A single, beautifully framed A3 print can serve as a stunning focal point above a desk or console table, while also acting as the perfect centrepiece to build a dynamic gallery wall around.

Framing Larger Photographs and Collages

While smaller photos are charming, an A3 frame gives a truly special photograph the presence it deserves. This size is perfect for showcasing a spectacular landscape from your travels, a professional family portrait, or a cherished wedding photo. It also provides ample space to create a bespoke photo collage, weaving together multiple smaller moments into one impactful piece that tells a unique story.

Professional Use: Certificates, Diplomas, and Signage

Step into any professional office, and you’ll likely see A3 frames used to display important qualifications, diplomas, and industry awards. The generous size lends a sense of prestige and ensures the text is easily readable. This professional, polished look also makes the A3 frame size a superb choice for customer-facing signage in reception areas, cafes, and boutiques, clearly communicating information with a touch of class.

To Mount or Not to Mount? Elevating Your A3 Print

Once you’ve chosen your beautiful A3 print, the next decision is how to present it. While you can place it directly into an A3 frame, adding a picture mount is the secret to achieving a truly professional, gallery-quality finish. A mount, also known as a mat, does more than just fill space; it’s a crucial element that protects and enhances your artwork.

The right mount creates a visual ‘breathing space’ between the art and the frame, preventing the composition from feeling cramped. This clean border draws the viewer’s eye inward, focusing attention squarely on the print itself. It’s a simple addition that dramatically elevates the final look, making it a key consideration when selecting the perfect a3 frame size for your piece.

What is a Picture Mount and Why Use One?

A picture mount is a specially cut piece of acid-free cardboard that sits between your artwork and the frame’s glass. Its purpose is twofold: protection and presentation. By creating a small air gap, it prevents the print from making direct contact with the glass, which can cause damage from condensation over time. Aesthetically, it adds depth and structure, giving your print a polished, deliberate, and professional appearance.

How a Mount Affects Your Frame Size Choice

This is the most important rule to remember: if you use a mount with your A3 print, you will need a frame that is larger than A3. Forgetting this can lead to a frame that simply won’t fit.

Let’s use a practical example. An A3 print measures 297 x 420 mm, as defined by the ISO 216 international paper size standard. If you add a classic 50mm (5cm) mount border around it, the total mounted size becomes approximately 400 x 520 mm. This combination would then fit perfectly within a standard A2 frame (420 x 594 mm). Always measure your artwork and add the width of your desired mount border (times two) to determine the final dimensions you need. Getting this right is essential for your final a3 frame size calculation. Our bespoke framing service can create the perfect mount and frame combination, taking all the guesswork out of the process.

Choosing a Mount Colour and Style

The right mount colour can beautifully complement your artwork. Here are a few popular approaches:

  • Classic White: A crisp white or a softer off-white mount is a timeless choice that works with almost any artwork and interior style.
  • Complementary Colour: Selecting a mount colour that picks up on a subtle accent in your print can create a wonderfully cohesive and curated look.
  • Double Mounts: For added sophistication, a double mount uses two layers, with the inner layer providing a thin, contrasting border. This adds an incredible sense of depth to the finished piece.

Choosing the Right A3 Frame Style for Your Space

Once you’ve settled on the perfect a3 frame size for your print, the next step is a journey into style. A frame is much more than a simple border; it’s the crucial bridge connecting your artwork to your room’s décor. The right choice will elevate both the print and the space it inhabits. The material, colour, and profile width all play a vital role in creating a cohesive and beautiful final look that honours your art.

Frame Materials: Wood, Metal, and Modern Finishes

The material of your frame sets the foundational tone. Each offers a distinct personality to complement your art and interior style:

  • Wood Frames: Crafted from materials like oak or pine, wooden frames bring natural warmth and a timeless, traditional feel. They are perfect for classic art, family portraits, and rustic interiors.
  • Metal Frames: Typically made from sleek aluminium, these provide a sharp, contemporary look. Their minimalist appeal is ideal for modern photography, posters, and abstract art.
  • Polcore Frames: A fantastic and versatile alternative, Polcore is a modern composite material made from recycled polystyrene. It offers a smooth, clean finish and is available in a huge range of colours and styles, providing a premium look at an affordable price.

Matching Frame Colour to Your Artwork and Décor

Colour is your tool for creating harmony. The goal is to choose a shade that enhances the artwork without overpowering it. Consider these classic pairings:

  • Black or White: The ultimate versatile choice. A simple black or white frame allows the art to be the hero, suiting almost any print and décor style, from monochrome to vibrant colour.
  • Natural Wood Tones: These beautifully complement nature scenes, botanical prints, and art with a warm palette. The organic grain adds texture and depth.
  • Gold or Silver: For a touch of elegance, metallic frames are unmatched. They can elevate a formal certificate, a classical print, or a special photograph, adding a sophisticated finish.

Moulding Profile: From Simple & Modern to Ornate & Classic

The ‘moulding profile’ refers to the shape and width of the frame itself. This detail can dramatically alter the final impression. A thin, flat profile offers a clean, minimalist feel, perfect for a contemporary gallery wall where the art is the sole focus. Conversely, a wider or more ornate profile makes a bold, traditional statement. It draws the eye and can transform a simple print into a significant feature piece, adding a sense of grandeur and importance.

Considering the style of your art is paramount. A modern abstract piece will sing in a thin metal frame, while a classic watercolour may call for the warmth of oak. Whatever your vision, finding the perfect style for your a3 frame size is a rewarding final step in bringing your art to life. Browse our curated collections to find inspiration and the perfect frame for your space.

Ready-Made vs. Bespoke A3 Frames: Which is Right for You?

Once you’ve chosen your beautiful A3 print, the next crucial step is selecting the perfect frame. This often leads to a key decision: should you opt for a readily available off-the-shelf frame or invest in a bespoke creation? The answer depends entirely on your artwork, your budget, and the final look you want to achieve. Let’s explore both paths to help you make a confident choice for your space.

The Pros and Cons of Off-the-Shelf Frames

Ready-made frames are a popular choice, primarily for their convenience and affordability. You can find them in countless high street shops, often for under £20, making them a great option for framing simple posters, certificates, or children’s drawings. They are perfect for temporary displays or when you need a quick and easy solution for a standard a3 frame size.

However, this convenience comes with trade-offs. The range of styles, colours, and materials is often limited, and the quality can be inconsistent. Most standard frames use basic materials that lack the protective qualities needed for fine art, such as UV-filtering glass or acid-free mounts. This can leave your artwork vulnerable to fading and long-term damage from sunlight and acidic materials.

When to Invest in a Bespoke A3 Frame

A bespoke frame is more than just a border; it’s a vital part of the artwork’s presentation and preservation. It acts as the perfect bridge between your art and your room’s décor. Investing in a custom frame is the best choice when:

  • You are framing something valuable: For limited edition prints, original art, or irreplaceable photographs, a bespoke frame provides essential, conservation-grade protection to preserve its value and condition.
  • You want a perfect design match: With custom framing, you can select the precise moulding, colour, and mount to create a seamless, professional finish that perfectly complements both the artwork and your interior design.
  • Preservation is a priority: We use premium materials like acid-free conservation mount boards to prevent discolouration and UV-protective glazing to shield your art from 99% of harmful light.

Ultimately, a bespoke frame is an investment in the life and beauty of your art, ensuring your piece is not only displayed beautifully but is also protected for decades. If you have a special piece that deserves the finest presentation, professional craftsmanship is the answer. Get a quote for a bespoke A3 frame for your artwork.

Frequently Asked Questions About A3 Frames

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

An A3 frame is expertly crafted to hold a print measuring exactly 29.7 x 42 cm. While these are the internal dimensions your artwork will fit into, the frame’s overall external size will be larger. This depends on the width of the beautiful, handcrafted moulding you select. When you purchase an A3 frame, you can be confident the aperture is perfectly sized to provide a snug and secure home for your cherished piece.

Will an A3 print fit in a 30×40 cm frame?

An A3 print can technically fit inside a 30×40 cm frame, but it is not a perfect match. Since A3 paper measures 29.7 x 42 cm, the frame is slightly wider but 2 cm shorter. This means the top and bottom of your artwork will be cropped. This can work if the main subject is centred, but for a flawless presentation, we always recommend a frame specifically made for the A3 format or using a custom mount.

Is A3 a good size for a gallery wall?

Absolutely! A3 is a spectacular and versatile size for creating a gallery wall. It strikes the perfect balance, offering enough presence to act as a central focal point without overwhelming the other pieces. You can use a single A3 print as the anchor for your collection, surrounded by smaller A4 and A5 frames. Its scale allows it to shine on its own or harmonise beautifully within a larger, curated display, bringing your entire wall to life.

How much bigger should my frame be if I want to add a mount to my A3 print?

To give your A3 print a professional, gallery-quality finish, we suggest adding a mount with a border of 5-8 cm on all sides. For a classic 5 cm border, you would need a frame with an internal aperture of approximately 40 x 52 cm. This essential breathing room prevents the artwork from feeling cramped and beautifully draws the viewer’s eye inward, enhancing the visual impact of the art and completing its story.

Can I buy just an A3 frame for a picture I already own?

Yes, of course. We believe every piece of art deserves a perfect home, which is why we offer our premium frames for sale individually. If you have a treasured A3 print or photograph, selecting one of our standalone frames is a wonderful way to elevate it. Choosing the right a3 frame size and style is a key step, and our bespoke craftsmanship ensures your existing picture will be protected and displayed with the elegance it deserves.

What is the difference between an A3 and A4 frame?

The primary difference between an A3 and A4 frame is simply size. An A4 frame is designed to hold paper measuring 21 x 29.7 cm, which is standard for letters and certificates. An A3 frame holds paper that is exactly double that size, at 29.7 x 42 cm. This makes A4 ideal for smaller photos and documents, while the more substantial A3 format is perfect for art prints, posters, and photographs you wish to turn into a true statement piece.
