Frequently Asked Questions
What is the exact Twitter header size?
1500×500 pixels (roughly 3:1). Bigger files are downscaled by X, so delivering exact size keeps text crisp.
Will my header be cropped on mobile?
Mobile crops the header to a narrower band. Keep names and logos in the central third to survive both layouts.
What file format does X accept?
JPG and PNG. JPG at quality 85% is plenty for a header and loads fastest.
