X header size
The X header is 1500×500. The profile photo is 400×400 and overlaps the lower left. The in-feed photo we export is 1600×900.
The header on an X profile is 1500×500 pixels, a 3:1 strip. The profile photo is 400×400 and is drawn as a circle that covers the lower-left of that strip. X’s own customization help is the reference for both; the display also changes with the window.
Two practical consequences, which the overlay marks:
- About 60 pixels can disappear from the top and the bottom depending on the screen. That is 12% of 500. Do not put a logo on the top edge and assume it survives.
- The avatar is not a small badge. In the full-resolution file it covers a disc whose center sits near the bottom edge, left of center. A wordmark in that corner will be under the photo on every profile view.
| Asset | Pixels | Watch for |
|---|---|---|
| Header | 1500×500 | Vertical crop, avatar overlap |
| Profile | 400×400 | Circle |
| In-feed photo | 1600×900 | 16:9 |
The post image
1600×900 is a 16:9 photo at a size that stays sharp when X shows it large. You will also see 1280×720 in 2026 roundups. Same ratio, fewer pixels. Either is the right shape. This tool exports 1600×900 so you are not upscaling a 720p still for a timeline that can show more.
A very tall or very wide original will be cropped to 16:9, not stretched. Set the focal point on the subject before you export, or the default center crop will keep the middle and drop the sides.
Profile photos
400×400 is the working size. The corners are outside the circle, same as Instagram and LinkedIn. A mark that touches the corner of the square will be clipped. Export PNG if the avatar is a logo on a plain field; export JPG for a photograph.
One photo, header and post
The header and the post do not share a crop, and they should not. The header is a short strip with a hole in the lower left. The post is a 16:9 frame with no hole. Drop the photo once, preview the header, place the focal point, then preview the post. Each preset keeps its own frame, so fixing the post does not shove the header back to center.
Download both. The names will be photo_x-header_1500x500.jpg and photo_x-post_1600x900.jpg.
