Twitter / X banner best practices
Tested principles for creatives that perform.
- Design around the profile photo overlap. Your profile photo (a circle) sits in the bottom-left corner of your header, covering roughly 200×200 px. Keep the left third of your banner design free of critical visual information.
- Use a 3:1 landscape composition. The Twitter / X header is 1500×500 px - an unusual 3:1 aspect ratio. The 728×90 Leaderboard is the closest AI-generated format at 8:1; generate at this size, then scale to 1500×500 and crop.
- Strong subject on the right, clean background on the left. The right side of the header is unobstructed by the profile photo. Placing your key visual there - with a gradient or minimal background on the left - is the most reliable layout.
- Test on both light and dark Twitter themes. Twitter / X users can switch between light, dim, and dark themes. A header that looks great on white can be harsh or jarring on Twitter's dark blue background.
- Bold, simple design at screen-fitted size. Twitter displays your header at a reduced size on most viewports. Fine detail, small text, and complex patterns all become muddled - prioritise bold, graphic compositions.
- Update the header for campaigns and events. Twitter / X profiles are visited frequently by followers and prospective followers. A seasonal or campaign-specific banner signals that your account is active.
