Helps avoid awkward crops and oversized uploads.

Placement

X header images are wide banners, so composition and safe margins matter more than maximum file size alone.

Do not edit the only copy of your image. Keep the original before using this page.
Do not judge the result by file size alone. Open the downloaded image and check important details.
Do not place faces, logos, or text at the outer edge. Platform previews can crop differently across devices.

Prepare a profile image, post, banner, thumbnail, listing, or cover image before uploading to the platform.
Make one version for the exact placement instead of reusing a random crop from another network.
Preview the image after upload when the platform provides a preview screen.
