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 displays headers differently on desktop and mobile. Mobile may crop more from the top and bottom. 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. Animated GIFs can be used for profile pictures with X Premium.
