Crop Image for Twitter Header
3:1 ratio, 1500×500 - crop is ratio-locked for you, free and entirely in your browser.
X (Twitter) headers display at a wide 3:1 aspect ratio, officially 1500×500 pixels. The header is also partially covered by your circular profile photo in the lower left, so composition matters as much as ratio. Cropping to an exact 3:1 here means the upload preview matches what followers actually see.

Frequently asked questions
Why does my header look different on my phone versus desktop?
The site crops the header slightly differently per device and screen width. Keep essential elements in the middle 60% of the 3:1 frame and nothing critical near the edges.
What area should I keep clear for the profile picture?
The avatar overlaps the bottom-left corner of the header - roughly the leftmost 15% and bottom 40% on desktop. Avoid placing logos or text in that zone.
