X (Twitter) header size: resize to 1500×500
Updated Nothing is uploaded
The X (formerly Twitter) header is 1500 × 500 px — a 3:1 banner — and up to 5 MB. Resize any image to fit, see which strip stays visible, and make a matching 400 × 400 profile picture.
Top and bottom ~70 px can be cropped; the profile picture overlaps the lower left.
How to resize
- Pick the X header size you need (the most common one is selected).
- Choose your image — it's resized instantly in your browser.
- Fill (crop) to cover the frame and drag to choose what's kept, or Fit (no crop) to keep the whole image with a colour or blurred background.
- Download and upload it straight to the platform.
