Photo Crop Calculator
Photos are 3:2 or 4:3, but many print sizes are not. Pick a size and drag the frame to see exactly what stays in the print.
Will my photo print sharp?
Drop in a photo and we read its pixel size on your device. Nothing is uploaded. You get the largest size that prints sharp, and a verdict for every size we make.

What gets cropped at each size?
Photos are 3:2 or 4:3, but a 8x10 is 4:5 and A4 is 1:1.41. Pick a size and drag the frame to see what stays in the print.
What size for my wall?
Measure the wall and the furniture under it. We work out a size that looks right and where to hang it. Or start from a print size and see how it looks on three typical walls.
How the crop tool works
Every print size has a shape. Most photos are a different shape, so something has to go. This shows you what.
Draws the print shape
It lays the outline of the size you chose over your photo and fills it edge to edge, the way we print by default.
You choose what stays
Drag the photo to move it inside the frame and zoom to tighten the crop. The faded area is what will not print.
Checks it stays sharp
It counts the pixels left inside the frame and tells you whether that area still prints sharp at the size you picked.
Which sizes crop your photo, and by how much
Based on a normal 3:2 camera or phone photo. 4:3 phone photos crop about 11 percent less into A sizes and more into 4R.
| Print size | Cut from a 3:2 photo | How much | Also fits |
|---|---|---|---|
| 4R, 6R, S8R, S12R(3:2) | Nothing | Full photo | 12x18, 16x24, 20x30, 24x36 |
| 5R (5x7)(5:7) | About 7% of the long side | Small trim | Postcard 4x8 crops 11% of the short side |
| A4, A3, A2(1:1.41) | About 6% of the long side | Small trim | A5, A1, A0 |
| 8R (8x10)(4:5) | About 17% of the long side | Noticeable | 16x20 |
| 6x8, 12x16(4:3) | About 11% of the long side | Small trim | Fits 4:3 phone photos with no crop |
| 8x8, 12x12(1:1) | A third of the long side | Heavy | Square prints and coasters |
Common questions
Before you order
Yes. Our editor fills the paper by default, the same rule this tool uses, and lets you drag the photo to set the crop. Set it the same way and the print will match what you saw here.
Yes. Ask for fit instead of fill and we print the full photo with white bands on two sides, or choose a size with the same shape as your photo from the table above.
For a ready-made frame with a mat, keep anything important 5 mm inside the edge. For a frame without a mat, 2 to 3 mm is enough.
Zooming in throws pixels away. Zoom out, or choose a smaller print size, or send us the file and we will check it by eye.
