How to Make a Twitter / X Header Image (1500×500)

The X profile banner is a flat 3:1 (1500×500) strip with two traps: the avatar overlaps the bottom-left, and mobile crops sides top and bottom. Design to those rules and the header finally looks intentional.

The short version

Follow the steps below with the free Crop Image tool — it runs entirely in your browser, needs no upload, account or watermark, and finishes in about a minute.

Step by step

1
Crop your art to 3:1

Use the custom ratio in the crop tool (3:1) or resize then trim.

2
Resize to 1500×500 exactly

Locked ratio in the resizer, one click.

3
Clear the avatar zone

Bottom-left belongs to your profile picture on most views — keep it quiet.

4
Keep it under 5 MB

JPEG at quality ~90 lands around 200–400 KB and renders instantly.

Pro tips & common mistakes

  • Place the tagline slightly right of centre — it never gets covered.
  • Test at 1500 px wide on a phone before committing.
  • Dark theme is the default app look — dark-friendly colours on mid-tone backgrounds survive both.
