Frequently asked questions
What size should a YouTube thumbnail be?
YouTube recommends 3840x2160 pixels (16:9) for the best quality on large screens. If you upload from a phone, keep the file under 2 MB — our mobile-safe preset exports 1280x720 and compresses automatically.
Can I see how my thumbnail looks on mobile?
Yes. Switch to Mobile preview to see an approximate suggested-feed size, and enable safe zones to avoid the duration badge in the bottom-right corner.
Why does my text get cut off on mobile?
YouTube overlays the duration badge in the bottom-right corner and crops thumbnails differently across the app, the home feed and search results. Keep faces and text inside the safe zone shown in the preview, and avoid the bottom-right corner entirely.
How is this different from the thumbnail resizer?
The studio adds text, layouts, and preview modes. The resizer is a one-step tool when you only need to fit an image to YouTube dimensions.
