X (Twitter) header size at a glance

Where the avatar and the profile text land

1500 × 500 is the size X publishes for a profile header, and the 3:1 shape is unusually wide — wider than almost anything else you will export. It is displayed responsively, so on a narrow window the same image is scaled down and the top and bottom edges can be trimmed slightly to keep the ratio.

The complication is everything drawn over it. The circular avatar overlaps the bottom-left corner and, on mobile, the display name and handle sit directly beneath in a way that pushes the visible band upward. Treat the bottom-left quarter as unusable: a logo placed there is behind the profile picture on every view.

Because a header is only ever seen a few hundred pixels tall in practice, fine detail and small text do not survive. A single strong image, a flat colour field or a simple pattern reads better than a composition. Keep the export under the 2 MB cap — easy at this size for a JPEG, less so for a PNG photograph.

How to resize an image to 1500 × 500

  1. Drop your image on the panel above — or paste it, or drop several at once to do a batch.
  2. The width and height are already set to 1500 × 500, and the aspect lock is off so both numbers are honoured exactly.
  3. If your source is a different shape, crop it to 3:1 first — resizing a different ratio straight to these numbers stretches it.
  4. Pick an output format. JPEG for photographs, PNG for flat colour, text and anything needing transparency.
  5. Download. Nothing was uploaded at any point — the resize ran on your own machine, in this tab.

Questions

Why does my header look cropped on a phone?

The header is scaled to the window width and held at 3:1, so a narrower viewport shows a shorter band of it. Content near the top and bottom edges is the first to go.

Does the avatar overlap the header?

Yes, at the bottom left. Leave that corner clear or the profile picture sits on top of whatever you put there.
