What is the Twitter/X header size?

Twitter recommends 1500×500px for the header banner. On mobile, it displays at 500×200px — keeping key content in the left-center gives the best cross-device view.

What is the Twitter profile picture size?

Upload at 400×400px minimum. Twitter displays it at 200×200px on desktop and 48×48px on mobile — but the high-res upload stays sharp.

Does Twitter crop the header banner?

Yes. On mobile, the center 500px is shown. Place your logo or key text in the left-center area so it remains visible everywhere.

Will my Twitter header work on X.com?

Yes. X.com uses the same 1500×500px dimensions as Twitter. Resize once and use across both platforms. Resizing happens entirely in your browser, so the image never leaves your device. You can keep the aspect ratio or set exact dimensions depending on your needs.

Is this tool free to use?

Yes. There is no charge, no account, and no watermark on the output. Resizing happens entirely in your browser, so the image never leaves your device. You can keep the aspect ratio or set exact dimensions depending on your needs.
