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

Bespoke framing is the ultimate step up, transforming a simple picture into a beautifully presented and protected work of art.

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.
