Your header is the billboard at the top of your profile. Twitter needs 1500×500 pixels. Wrong dimensions get cropped or look stretched.

aspect ratio

Twitter uses a 3:1 aspect ratio for headers. 1500×500 gives you the full canvas without compression. Mobile users see a cropped center portion, so don't put logos or text at the edges.

Your header is the first thing visitors see on your profile. A stretched or pixelated banner makes your entire account look unprofessional. The right dimensions signal you know what you're doing.
