Quick answer

Use a 16:9 image with clear contrast, readable text, and a centered subject so the thumbnail remains understandable when displayed small.

YouTube thumbnails need strong composition at small preview sizes, so readable text and subject placement matter as much as raw dimensions.

Focused on a specific platform placement.

Connects platform guidance to the browser editor.

Helps avoid awkward crops and oversized uploads.

Placement

YouTube thumbnails need strong composition at small preview sizes, so readable text and subject placement matter as much as raw dimensions.

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.
