X (Twitter) header and post sizes

The X profile header is wide and short, commonly prepared around 1500 × 500 pixels (a 3:1 ratio). RealResizer’s X preset locks that exact shape so your header banner is framed correctly across mobile and desktop.

In-stream images on X are displayed in a wide 16:9 frame (often 1600 × 900), and your profile photo is a square. The same tool can switch between these, so you can prepare a consistent header, post, and avatar without leaving the editor.

How to resize an image for X (Twitter)

  • Upload or drag and drop an image into the tool.
  • Choose the X header, post, or profile preset to match your destination.
  • Adjust the crop to frame the most important part of the image.
  • Cut and preview the result across devices.
  • Export in your preferred format.

Cropping considerations for X

Banners are almost fully covered on mobile, so keep text and logos within the central safe area rather than the far edges. For post images, a wide 16:9 crop reads well in the feed and avoids the awkward auto-cropping that happens when the platform resizes your image.
