Reddit image sizes in 2026
Portrait 4:5 is the tallest shape the feed shows without cropping on phones. Keep the subject of a community banner away from the bottom-left, where the icon and name sit.
| Use | Size (px) | Ratio |
|---|---|---|
| Community banner | 1920 x 384 | 5:1 |
| Community banner (mobile) | 1600 x 480 | 10:3 |
| Community icon | 512 x 512 | 1:1 |
| Profile picture | 512 x 512 | 1:1 |
| Profile banner | 1600 x 480 | 10:3 |
| Post image (portrait) | 1080 x 1350 | 4:5 |
| Post image (square) | 1080 x 1080 | 1:1 |
| Post image (landscape) | 1920 x 1080 | 16:9 |
| Link thumbnail | 1200 x 628 | 1.91:1 |
A worked example
Take a typical iPhone photo, 4032 x 3024 (4:3):
- Community banner (1920 x 384): the full width is kept, the height is cut to 806 px, so about 73% of the height is lost before scaling to 1920 x 384.
- Community banner (mobile) (1600 x 480): the full width is kept, the height is cut to 1210 px, so about 60% of the height is lost before scaling to 1600 x 480.
- Community icon (512 x 512): the full height is kept, the width is cut to 3024 px, so about 25% of the width is lost before scaling to 512 x 512.
- Profile picture (512 x 512): the full height is kept, the width is cut to 3024 px, so about 25% of the width is lost before scaling to 512 x 512.
The resizer draws that cut on your own file before you export, so you can drag the frame to keep the subject in view.
What the tool is doing
It reads the pixel size of your file in the browser, draws it on a canvas, crops it to the shape you pick and re-encodes it at the exact export size. There is no upload request, and metadata such as EXIF location is not carried over.
Image shape and attention in the feed
Most Reddit browsing happens on phones, where a taller image takes more of the screen. A portrait 4:5 image is the tallest shape most feeds show without cropping, so it holds attention longer than a wide landscape one. The format gets the post noticed; the reactions it earns in the first hours decide how far it goes.
