What is Twitter/X Header format?

Twitter/X profile header banners display at 1500x500 pixels in a 3:1 landscape aspect ratio. The header banner is the large background image at the top of your Twitter/X profile page. It's one of the first things people see when visiting your profile, and a correctly sized banner looks professional and polished. Twitter crops images that aren't 1500x500, so resizing beforehand ensures nothing gets cut off.

How to resize for Twitter/X profile headers

  1. Upload your image — JPG, PNG, or WebP format.
  2. Choose "Fit + Black Bars" to preserve the full image, or "Stretch to Fill" for full 1500x500 coverage.
  3. Download and upload as your Twitter/X profile header.
