Twitter / X Header Size (1500×500)
The X (Twitter) header is 1500×500 pixels — a wide 3:1 banner. Resize your header to the exact size below, and keep key content centered so it survives mobile cropping. It runs in your browser, so nothing is uploaded.
Mind the crop
The X header is a wide 3:1 strip, and it crops heavily on mobile — desktop shows the full 1500×500, but phones show roughly the center third. Keep logos and text inside a center safe zone of about 1250×400 so nothing important is cut off.
Also remember your profile picture overlaps the lower-left of the banner, and your name and bio can sit over the bottom edge. Design around those areas — decorative background at the edges, key content centered.
How to make an X header
- Keep your logo and key text in the center of the design, away from the edges and lower-left.
- Upload your image here — the target is already set to 1500×500.
- Untick 'Keep the original shape' if it is not already 3:1, then click Resize.
- Download your 1500×500 header and upload it to X.
X header — FAQ
What size is a Twitter / X header?
The X (Twitter) header photo is 1500×500 pixels, a 3:1 aspect ratio — much wider than it is tall. Upload at that exact size so it fills the banner space without stretching.
Does the X header get cropped?
Yes, heavily on mobile. The full 1500×500 shows on desktop, but mobile displays roughly the center portion. Keep logos and key text within the center — a safe zone of about 1250×400 — so nothing important is cut off.
Where does my profile picture sit on the X header?
Your profile picture overlaps the lower-left of the header, and the bottom of the banner is partly covered by your name and bio on some layouts. Avoid putting important content in the lower-left corner.
What format should an X header be?
Use JPG or PNG, under the platform's file-size limit. JPG is fine for photographic banners; use PNG if your header has sharp text or a logo that needs to stay crisp.
Is my image uploaded to a server?
No. This tool runs entirely inside your browser. Your image never leaves your device, so nothing is uploaded anywhere.
