How it works
- 1Drop your banner image in — a wide photo or a design export both work.
- 2It is scaled and center-cropped to exactly 1500 × 500 pixels, the 3:1 shape the header uses.
- 3Keep the lower-left corner clear before you upload: your profile picture sits over it on every layout.
Frequently asked questions
- Why does my header look different on my phone?
- Because the 3:1 shape has to fit screens of very different widths. On a narrow display the app keeps the height and trims the sides, so content near the left and right edges disappears. Anything that must always be visible belongs near the centre.
- Where exactly does the profile picture sit?
- Over the lower-left area of the header, overlapping it by roughly half the avatar's height. It is the most reliable way to lose a logo — placing branding bottom-left works in the file you exported and is covered on the live profile.
- Can I use a photograph rather than a designed banner?
- Yes, but 3:1 is an extreme ratio. A photo cropped to it keeps only a horizontal slice, so images with a clear horizon or a repeating texture work far better than ones with a single subject. Crop deliberately before compressing rather than letting the centre crop decide for you.
- Does X re-compress the header?
- Yes, like every image on the platform. Uploading at the display size means the re-compression is the only processing your banner goes through, instead of a resize and a re-compression stacked together — noticeably better on gradients and flat colour, which is where banner artefacts usually show.
About this tool
The header is the widest image on a profile and the one most often mangled, because 3:1 is a shape almost nothing is shot in. Filling 1500 × 500 with a normal photograph keeps a narrow horizontal slice of it, so the crop deserves a deliberate decision rather than whatever the centre happens to catch.
Two parts of the frame are unreliable. The lower-left corner is covered by your profile picture on every layout, which is exactly where people tend to put a logo. The left and right edges are trimmed on narrow screens, since the app preserves the height and cuts the width. Between them, the safe region is a band across the centre — plan the design around it and the header survives every device.
Uploading at the display size also improves what the platform's own compression does to your image. X re-encodes everything it receives; handing it a file already at 1500 × 500 means that re-encode is the only processing applied, rather than a resize and a re-encode together. The resize and compression here run entirely in your browser, so the banner is never uploaded to this site and your original is untouched.
