YouTube thumbnail size and channel banner guide

YouTube's current English help recommends a 3840 × 2160 custom thumbnail in 16:9. Channel art is a separate 2560 × 1440 asset with a much narrower cross-device safe area.

Shorts and high-resolution exports

YouTube does not handle Shorts thumbnails like long-form video thumbnails: creators select a frame for a Short rather than upload the same custom thumbnail file in all surfaces. Check the current mobile publishing flow before designing a separate asset.

A 3840 × 2160 canvas uses substantially more memory than 1280 × 720. Start with a sharp source, export one high-resolution thumbnail at a time on constrained devices, and compress only after checking text edges and faces.

2

Frame them independently

Use a tight subject crop for the thumbnail and a wider center-safe composition for channel art.

Check file size and upload preview

If the upload is too large, compress a copy and verify it again before publishing.

Is 1280 × 720 wrong?

It is still 16:9 and may work, but YouTube's current English help recommends 3840 × 2160. Some localized help pages can lag, which is why this guide shows its check date.

Can I use the channel banner as a thumbnail?

No. They use different composition rules. Banner content must survive narrow cross-device cropping, while a thumbnail fills a 16:9 video card.
