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).

A3

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 |

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?
Usually yes. Photos from iPhones and modern Android phones taken in good light print sharply at A2 and comfortably at A1. Upload the original file rather than a compressed message copy.
