Resize an Image for X (Twitter)
Header, posts and profile: the exact X (Twitter) dimensions so your images look sharp and frame correctly.
For X (Twitter), use 1500×500px for the header/banner, 1600×900px (16:9) for an in-post image, and 400×400px for the profile photo. Crop to each ratio first, then resize to the pixels so your image isn't awkwardly cropped in the timeline.
| Header / banner | 1500 × 500 px (3:1) |
|---|---|
| In-post image | 1600 × 900 px (16:9) |
| Profile photo | 400 × 400 px (square) |

Compress and post
Lightly compress so it uploads quickly without visible loss.

- Profile photos display as a circle, so centre the subject.
