What 1:1 means
An aspect ratio of 1:1 means the width and the height are the same, so the picture is a square. A 1:1 picture has the same ratio at any size: 512 x 512, 1080 x 1080 and 2048 x 2048 pixels are all 1:1.
Pixel sizes for 1:1
| Size | Typical use |
|---|---|
| 256 x 256 | Small avatars and icons |
| 512 x 512 | App icons, profile pictures and thumbnails |
| 1080 x 1080 | Square social media posts |
| 1200 x 1200 | Product and listing images |
| 2048 x 2048 | Large product images that can be zoomed |
Sites and marketplaces have their own rules, so check the minimum and recommended size for the one you use.
How to crop to 1:1
- Open the image. The box is already square.
- Move and resize the box over the part you want to keep.
- Choose an output size, or keep the size of the box.
- Select Crop image and download.
If the picture is smaller than the size you choose
Choosing 2048 x 2048 for a 600 pixel box enlarges the picture, and enlarging cannot add detail. Pick an output size close to or below the size of the box for the sharpest result.
1:1 without cutting anything off
To keep the whole picture and add a coloured border instead, use crop to square with the background option.
