Why this size
Which crop ratio to use
A ratio is the shape of the frame: 1:1 is a square, 4:5 a slightly tall rectangle, 16:9 the widescreen shape of videos and slides. Locking the ratio keeps that shape while you move and resize the frame, so the result fits where you post it without the app cropping it again.
Cropping never re-scales what is inside the frame, so the part you keep is as sharp as the original. To make the result an exact size as well, crop here first, then resize it to the pixels or cm you need.
| Ratio | Shape | Use it for |
|---|---|---|
| 1:1 | Square | Instagram posts, profile photos |
| 4:5 | Tall | Instagram portrait posts |
| 3:4 · 2:3 | Tall | Portraits and photo prints |
| 3:2 | Wide | 4 x 6 prints, camera photos |
| 16:9 | Wide | YouTube thumbnails, slides |
| 9:16 | Tall | Stories, Reels, Shorts |

How we checked this page
Checked by the SizePort team on .
We test the tool with sample photos before it goes live and check that the sizes on this page match what it produces. Rules and platforms change, so if something here is out of date, tell us and we will correct it.
How the tool works
The tool keeps the pixels inside the frame you choose and removes the rest. Nothing is scaled, so the part you keep is as sharp as the original. Everything happens in your browser; your images are never uploaded.
