Why A0 Cuts Things Off
Every A size is defined from A0: one square metre at 1:1.41, halved to make A1, halved again for A2. At 300 DPI an A0 would be 9,933×14,043 pixels, around 140 megapixels, which no phone and almost no camera produces. Seen from a metre or two, about 100 pixels per inch is enough. We deliver about 3,364×4,756, roughly 102 per inch: right for a poster read from a few steps away, soft if someone presses their nose to it. That's the honest limit at A0, for any photo.
Instead of trimming your photo down to the shape, we generate more of the scene around it until it fits — and sharpen the whole image in the same pass.
Where A0 shows up
- Scientific and academic conference posters
- Trade-show and shop-window displays
- Site plans and technical drawings
- Memorial and celebration boards for large venues
Pixels an A0 print needs
- Sharp in your hand (300 DPI)
- 9,933 × 14,043 px
- Sharp on a wall (150 DPI)
- 4,967 × 7,022 px
A smaller photo still prints, just softer. Check yours against every size on the print size chart. Changing the DPI setting alone doesn’t add pixels: how to convert an image to 300 DPI.
