The header banner on X is a wide 3:1 strip at 1500x500 pixels. Upload your image below and crop it to that ratio so the banner fills the space properly instead of being stretched or cropped by the site.
| Recommended size | 1500 x 500 pixels |
|---|---|
| Aspect ratio | 3:1 |
| Supported formats | JPG, PNG, GIF (non animated) |
| Maximum file size | 2 MB |
| Avatar overlap | Bottom left corner is covered by your profile picture |
| Mobile crop | Top and bottom edges may be trimmed - keep content centred |
The header is cropped differently on desktop and mobile, and your profile picture overlaps the lower left corner. Designing at exactly 1500x500 and keeping that corner clear is the only reliable way to avoid losing part of the image.
The header banner is 1500 x 500 pixels, a 3:1 ratio, with a maximum file size of 2 MB.
Your profile picture sits over the bottom left of the banner, and mobile trims the top and bottom slightly. Keep logos and text away from those areas.
Yes. The banner dimensions did not change with the rebrand from Twitter to X, so 1500 x 500 pixels remains correct.
No. The header must be a static image. Animated GIFs are not supported for banners.
