A3 Snap Frames: High Impact Poster Display
Perfect for promotions, menus, and notices. Displaysense offers a premium range of A3 snap frames designed for businesses that need to make an impact. The A3 size strikes the perfect balance—large enough to catch attention, yet compact enough to fit in corridors and smaller wall spaces.
Our A3 poster frames feature a simple front-loading mechanism, allowing you to change your A3 paper size inserts in seconds without removing the frame from the wall. Whether you need a black A3 snap frame for a modern café or a classic silver frame for office signage, our collection offers professional quality at competitive prices.
Easy Poster Change
Update in seconds. The four spring-loaded sides of the A3 snap frame clip open by hand. Simply lift the edges, remove the cover, and swap your poster without tools.
Durable Aluminium
Built for business. Constructed from anodised aluminium, our frames are rust-resistant and sturdy. They maintain their professional look even in busy retail or hospitality environments.
Protective Cover
Crystal clear view. Each frame includes a UV-stable anti-glare PVC cover sheet. This protects your A3 picture frames content from fading in sunlight and keeps prints free from dust and moisture.
Perfect A3 Fit
Standard sizing. Designed specifically for A3 paper size (297 x 420 mm). Whether you print in-house or use professional signage, your posters will fit perfectly without needing to be trimmed.
Versatile Mounting
Flexible installation. Pre-drilled holes are hidden beneath the snap profile for a neat finish. All frames can be mounted in either Portrait or Landscape orientation to suit your design.
Secure Options
Tamper resistant. For public areas like lifts or restrooms, we offer lockable A3 frames that require a special Allen key to open, preventing unauthorised access to your posters.

Frequently Asked Questions
What is A3 paper size in cm?
A3 paper size is 29.7 x 42.0 cm (or 297 x 420 mm). This is exactly double the size of A4. Our frames are designed to fit this standard international ISO 216 size perfectly.
What are A3 poster frames used for?
A3 poster frames are ideal for medium-sized signage that needs to be noticed. Common uses include restaurant menus, promotional offers in retail windows, health and safety notices, and event posters in corridors.
Can I use them as A3 picture frames?
Yes. The sleek aluminium profile makes them excellent modern A3 picture frames for photos, art prints, or certificates. They are easier to use than traditional glass frames as you can swap the image without taking the frame off the wall.
How much of the poster is covered by the frame?
The frame profile (usually 25mm wide) overlaps the edge of your poster by approximately 10mm on each side. This overlap is necessary to hold the poster and cover sheet securely in place.
Are these frames suitable for outdoor use?
Standard frames are for indoor use. For outdoor signage, you must choose our Waterproof A3 Snap Frames. These feature a rubber gasket seal inside the frame to prevent water from damaging your poster.
What is the difference between A3 and A2?
A3 (297 x 420mm) is smaller than A2 (420 x 594mm). An A2 poster is exactly double the size of an A3 poster. A3 is great for close-up viewing, while A2 is better for viewing from a slight distance.
Do you include fixings?
Yes. All our frames come with a set of wall plugs and screws. The fixing holes are hidden underneath the snap frame profile, so the screws are invisible once the frame is snapped shut.
Do you sell replacement covers?
Yes. Over time, covers can become scratched or lost. We sell replacement A3 PVC cover sheets separately so you can refresh your frames without buying new units.
What colours are available?
While Silver is the most popular choice for a professional look, we also stock Black, White, Red, Blue, Green, and even wood-effect finishes to match your specific branding or interior decor.
Can I buy in bulk?
Yes. We offer significant discounts for bulk purchases of A3 snap frames. This is perfect for schools, hospitals, or retail chains outfitting multiple locations.
