Poster size guide
We print A5, A4, A3, A2 and A1 - sizes available vary by design. Here is how the sizes compare and where each one works best.
Visual comparison
Relative footprint of each A-size (drawn to scale).
A5
148 × 210 mm
A4
210 × 297 mm
A3
297 × 420 mm
A2
420 × 594 mm
A1
594 × 841 mm
Larger prints need higher-resolution files. Upload the original image rather than a compressed copy or screenshot for the sharpest A2 and A1 prints.
| Size | Millimetres | Inches | Best for |
|---|---|---|---|
| A5 | 148 × 210 mm | 5.8 × 8.3 in | Desk, shelf, small frame gallery |
| A4 | 210 × 297 mm | 8.3 × 11.7 in | Bedside, cluster of 3 – 5 prints |
| A3 | 297 × 420 mm | 11.7 × 16.5 in | Above a desk, kitchen, hallway |
| A2 | 420 × 594 mm | 16.5 × 23.4 in | Sofa, bed, statement print |
| A1 | 594 × 841 mm | 23.4 × 33.1 in | Feature wall, large lounge, classroom |
Framing tip: every poster ships at true A-sizes, so any standard IKEA, Amazon or high-street frame in A5, A4, A3, A2 or A1 fits without trimming.
Common questions
What size poster should I get for above a sofa?
A2 is our most-picked size for above a standard 3-seater sofa. If your sofa is oversized or the wall is very tall, A1 will hold the space better.
How big is A3 in inches?
A3 is 11.7 × 16.5 inches (297 × 420 mm). It is a great everyday size that looks substantial without dominating a room.
Can I get a custom size?
Yes - message our studio on WhatsApp with the dimensions you need and we will quote a bespoke price.
Will my phone photo print at A1?
It depends on the photo, not the phone. Most recent phone photos print well up to A2 or A3; A1 needs a genuinely high-resolution file. Upload the original (not a message copy or screenshot) and the editor's image-quality check will confirm the best size before you order.
