Important Notes
X (formerly Twitter) header images (also called banner images) display at the top of your profile page. The recommended size is 1500x500 pixels with a 3:1 aspect ratio. The header displays differently on desktop and mobile - on desktop, the profile picture overlaps the bottom-left area. Keep critical content centered and away from the edges for the best cross-device display.

Frequently Asked Questions
What is the best X (Twitter) header size?
1500x500 pixels (3:1 aspect ratio) is the recommended size. This provides the best quality across desktop and mobile devices. Maximum file size is 2MB.
Why does my X header look cropped on mobile?
X says up to 60 pixels at the top and bottom of a 1500x500 header can be cropped, depending on the monitor size and browser. Keep all important content centered vertically and horizontally to ensure it remains visible on all devices.
Where does the profile picture overlap the header?
On desktop, the profile picture is positioned in the bottom-left area of the header image. Avoid placing important text, logos, or other content in this zone to prevent it from being hidden.
What file format is best for X headers?
Use JPG for photographic headers to keep file sizes small. Use PNG for graphics with text or logos that need sharp edges. X also accepts GIF but renders it as static (first frame only). Maximum file size is 2MB.
Can I use an animated GIF as my X header?
No, X does not support animated GIFs for header images. Headers must be static images in JPG, PNG, or static GIF format. The same applies to profile pictures.
Recent Updates
Cropping now uses X's own figure (up to 60px at the top and bottom, depending on screen and browser), and the animated GIF answer no longer says Premium profile pictures can be animated: X supports neither.
