Enter a width and height to get the aspect ratio, or pick a ratio to calculate the missing side, and see which standard print sizes fit your image without cropping.
Divide width and height by their greatest common divisor. A 4,000 × 3,000 photo shares a divisor of 1,000, so its ratio is 4:3. A 1,920 × 1,080 image divides by 120 and gives 16:9.
To resize to a ratio, multiply the side you know by the other term and divide by its own: at 16:9, a width of 1,920 needs a height of 1,920 × 9 ÷ 16 = 1,080.
Print sizes come in a handful of ratios. A photo prints without cropping when its ratio matches the print's; otherwise part of it is trimmed off the long side.
| Aspect ratio | Print sizes |
|---|---|
| 2:3 | 4 × 6 in, 8 × 12 in, 12 × 18 in, 20 × 30 in, 24 × 36 in, 40 × 60 in |
| 5:7 | 5 × 7 in |
| 1:1 | 8 × 8 in, 12 × 12 in |
| 4:5 | 8 × 10 in, 16 × 20 in |
| 1:1.41 | A4, A3, A2, A1, A0 |
| 11:14 | 11 × 14 in |
| 3:4 | 12 × 16 in, 18 × 24 in, 30 × 40 in |
Most phones shoot 4:3 (12 × 16, 18 × 24 and 30 × 40 fit exactly). Most DSLR and mirrorless cameras shoot 3:2, the ratio of 4 × 6, 8 × 12, 12 × 18 and 20 × 30 prints. Instagram portraits are 4:5, a perfect match for 8 × 10 and 16 × 20.
No. The ratio only decides the shape and how much gets cropped. How large a photo prints sharply depends on its pixels, which the DPI checker shows for every size.
FAQ
Quick answers about ratios, crops and print sizes.
8 × 10 is 4:5. It matches Instagram portrait photos exactly; a 4:3 phone photo loses about 6% top and bottom.
