Resize a Photo to A2 Without Cropping
A2 (16.54×23.39 inches) = 4,961 × 7,016 px at 300 DPI, or 2,480 × 3,508 px for a print viewed from a step away (150 DPI).
A2 is 420×594 mm, about 16.5×23.4 inches: a proper wall poster, four times the size of A4. At that scale both the shape and the resolution start to matter. Upload your photo below and we'll extend the scene to A2 and rebuild it at poster size.

Why A2 Cuts Things Off
A2 sits close to an 18×24 poster in size but not in shape. 18×24 is 3:4, the phone's own proportions, while A2 is 1:1.41, noticeably taller. So a phone photo that drops cleanly into 18×24 still loses about six percent of its width at A2, and a 2:3 camera photo loses about the same off its top and bottom. The other half is pixels: 300 DPI at A2 is 4,961×7,016, about 35 megapixels, which few phone photos come near. We deliver about 3,363×4,756, roughly 200 pixels per inch. That's well past what the eye resolves from a poster's normal viewing distance of two to three feet.
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 A2 shows up
- Wall posters and art prints for a living room or office
- Exhibition, classroom and conference posters
- Prints ordered from shops that sell in A sizes
- Frames sold as A2 or 42×59.4 cm
Pixels an A2 print needs
- Sharp in your hand (300 DPI)
- 4,961 × 7,016 px
- Sharp on a wall (150 DPI)
- 2,480 × 3,508 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.
A2 Questions
Will my photo be sharp enough for A2?
From where people stand to look at a poster, yes. An A2 is about 29 inches corner to corner, and from that distance the eye needs only around 120 pixels per inch; we deliver about 200. Pressed up close it won't look like a small print, and no upscaler changes that.
Is A2 the same as 18×24?
Nearly the same size, a different shape. 18×24 is 3:4 and A2 is 1:1.41, so a file made for one is trimmed by the other. Use the page for the size you are printing.
