Resize a Photo to A4 Without Cropping
A4 (8.27×11.69 inches) = 2,480 × 3,508 px at 300 DPI, or 1,240 × 1,754 px for a print viewed from a step away (150 DPI).
A4 is 210×297 mm, the standard sheet almost everywhere outside North America, and no camera shoots its shape. Upload your photo below and we'll extend the scene to fill an A4 page instead of cropping it or leaving white bands.

Why A4 Cuts Things Off
Every A size is 1:√2, about 1:1.41, so the sheet keeps its shape when it's folded in half: two A4s make an A3, two A5s make an A4. That's neat for paper and awkward for photos, because 1:1.41 falls between a phone photo's 3:4 and a camera's 2:3 and matches neither. Filling A4 with a phone photo trims about six percent off the sides; a camera photo loses about the same off the top and bottom. It also isn't US Letter: A4 is narrower and taller, so a file made for an American printer is slightly the wrong shape here, and the reverse.
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 A4 shows up
- Full-page prints for buyers outside the US and Canada
- Printable wall art sold as A-size downloads
- Frames sold in centimetre sizes, where 21×30 cm is A4 in all but name
- Photos placed into A4 documents, reports and portfolios
Pixels an A4 print needs
- Sharp in your hand (300 DPI)
- 2,480 × 3,508 px
- Sharp on a wall (150 DPI)
- 1,240 × 1,754 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.
A4 Questions
What is A4 in pixels?
2,480×3,508 pixels at 300 DPI, the usual target for a sharp print. At 150 DPI, fine for a poster seen from a step away, it is 1,240×1,754.
If I make an A4 file, will it fit A3 too?
The shape, yes: every A size has the same proportions, so an A4 image scales to A3 or A2 without any cropping. For a sharp A3 it needs more pixels, which the A3 page builds in.
