X image sizes
- Post image: 1600×900 pixels (16:9). A single image shows uncropped at this ratio; multi-image grids crop further.
- Header: 1500×500 pixels (3:1). The bottom left is covered by your profile picture, and phones may trim the top and bottom, so keep the key part centered.
- Profile picture: 400×400 pixels, shown as a circle.
These reflect the sizes as of late 2026; the platform may change them.
How to fit your image
If your image has a different ratio, Fill crops the edges and Fit pads it with a solid color or a blurred background. For the 3:1 header a normal photo becomes a thin strip when filled, so Fit with a blurred background often looks better.
