What size is a Twitter/X profile photo?

Twitter/X displays profile photos at 400x400 pixels. They are shown as circles. Make sure your face or logo is centred.

The header (banner) image should be 1500x500 pixels. Note that the centre of the image is most visible on most devices.

Twitter/X Header Image Tips
