What is the recommended X header size?
The recommended size for an X header photo is 1500 × 500 px. That is a wide image with a 3:1 ratio, so a banner made for another size will need cropping.
Export the image at this size when you can. An image that is already the right size keeps its sharpness better than one that is scaled by X.
What gets cut off in the header?
The edges of a wide banner may be hidden on some screens, and the profile photo covers part of the lower left area. Keep text and important details in the centre of the image.
Preview the banner on a phone and a desktop before you publish, because the visible area can differ between them.
Do the header size rules change?
They can. X updates its image settings from time to time, so check the current size in the X help center before you upload a new header.
This page shows the recommended size only; it does not list every file limit or format rule.
How do I make a 1500 x 500 header?
Use any image editor that lets you set the canvas size, enter 1500 and 500 pixels, then place your design inside it. Export in a common format such as JPG or PNG.
Keep the file size reasonable. A very heavy image takes longer to upload and may be compressed.

Frequently asked questions
What is the X header size in pixels?
The recommended size is 1500 × 500 px. Check the X help center for the current rules before you upload.
Is this size guide free?
Yes. It has no sign-up and no daily limit.
Does the tool upload my image?
No. The size guide runs in your browser and does not send your files to a server.
Why does my header look blurry after upload?
It is often because the image was smaller than the recommended size and was enlarged. Start with an image at 1500 × 500 px.
Can I use a different ratio for my header?
You can, but X may crop the image. Use the recommended 3:1 ratio to keep control over what appears on screen.
