Lazy Load Code Generator
Generate image markup that loads late and never shifts layout.
Build a 1500 by 500 header that survives the crop.
Header, with the covered areas shaded
The Twitter Header Maker builds a 1500 by 500 header with both hazards drawn: the profile picture that overlaps the bottom left, and the shorter band mobile crops to. Designing without those overlays is why so many headers have their text cut in half.
The header on X is 1500 by 500 pixels, and two things eat into it: the profile picture overlaps the bottom left, and mobile crops the top and bottom to a shorter band. Designing without accounting for both is why so many headers have their text cut in half.
Both are drawn as overlays here, so you can see exactly what survives. Beyond that it is a straightforward canvas: a background photo, gradient or colour, text with the outline and shadow options that keep it readable, and a logo. The download is at full resolution and sized so it does not get re-compressed on upload.
The profile picture corner and the mobile crop band, both drawn so the safe area is obvious.
Exactly 1500 by 500, so nothing is resized on the way in.
Outline and shadow controls that keep type legible over a photographic background.
A photo, a gradient or a flat colour, each with the same overlays applied.
Downloaded at the native size rather than scaled up from a preview.
A photo, a gradient, or a flat colour at 1500 by 500.
One marks the profile picture corner, one the band mobile crops away.
Keep both inside the safe band and clear of the profile picture.
Save at 1500 by 500 and upload it as your header.
1500 by 500 pixels, a 3:1 ratio. Uploading at that size avoids any resizing on the way in.
Bottom left, roughly 200 pixels across in the 1500-wide image, extending above the bottom edge. Keep that corner clear.
Mobile shows a shorter band than desktop, trimming the top and bottom. The safe-area overlay marks the part that survives everywhere.
JPEG for photographic headers, PNG when there is flat colour or text with hard edges. Both are accepted; the size limit is generous.
