Will my photo fit the print size?
Most cameras shoot in a 3 : 2 ratio, but A4 and the other A paper sizes are 1 : 1.41, and frames such as 10 × 8 in are 5 : 4. When the ratios differ, you either crop the edges of the photo to fill the paper or leave a white border. Choose your photo and a print size and this checker shows exactly what is lost, lets you move the crop, and shows the white border you get if you print the whole image. Your photo is not uploaded anywhere. The table shows how much of each common photo ratio is cropped away on popular sizes. See also the print size calculator and the paper size guide.
| Photo ratio | Lost on A4 | Lost on 10 × 8 in | Lost on 12 × 8 in | Lost on 16 × 12 in |
|---|---|---|---|---|
| 3 : 2 (DSLR, mirrorless) | 5.7% | 16.7% | 0.0% | 11.1% |
| 4 : 3 (Micro Four Thirds, phones) | 5.7% | 6.3% | 11.1% | 0.0% |
| 5 : 4 (large format) | 11.6% | 0.0% | 16.7% | 6.3% |
| 16 : 9 (video frame) | 20.5% | 29.7% | 15.6% | 25.0% |
| 1 : 1 (square) | 29.3% | 20.0% | 33.3% | 25.0% |
Photo ratio questions
Why is my photo cropped when I print it on A4?
A 3 : 2 photo is wider than A4, which is 1 : 1.41. To fill the whole sheet about 6% of the photo is cropped from the long side. You can instead print the whole photo with a thin white border.
What print size matches a 3 : 2 photo exactly?
6 × 4 in, 12 × 8 in, 18 × 12 in and 24 × 16 in are all 3 : 2, so a full frame camera photo prints on them with no crop.
Which frame sizes suit a 4 : 3 photo?
16 × 12 in and 12 × 9 in are 4 : 3. For 10 × 8 in frames (5 : 4) a 4 : 3 photo loses only a few percent.
Should I crop before sending my photo to print?
It is best to choose the crop yourself so the main subject stays in the frame. If you send me the full file I will ask which part you want kept, and I leave a safe margin because some mounts cover the edges.
