X (Twitter) size guide

Twitter (X) Header Size: 1500x500 (2026)

The Twitter (X) header size is 1500x500 pixels at a 3:1 aspect ratio. One catch: your profile picture and bio overlay the bottom of the header on mobile, so keep anything important in the top 350 pixels.

X (Twitter) design tips that matter

Knowing the pixel sizes is half the battle. Here's what separates designs that get engagement from designs that don't.

Design for the top 350 pixels

Mobile users see most of the top of the banner. The bottom 150 pixels are usually behind your profile picture and bio.

Avoid stock cliches

Mountains and laptops are everywhere on X. A bold typographic banner with your tagline reads as more authentic.

Refresh for launches

If you're shipping a product or speaking at an event, swap your banner the week of. It's free real estate everyone sees when they land on your profile.

PNG over JPG for graphics

X compresses JPG aggressively for banners. PNG preserves text sharpness better.
