YouTube Shorts thumbnails: size, safe area and design tips
Most Shorts are discovered by swiping, but covers still matter on your channel page, in search and in the Shorts shelf. A clean, consistent cover makes your Shorts look intentional.
Shorts cover size
Shorts are vertical, so covers are 9:16 — design at 1080×1920. Different surfaces crop the cover differently, so keep the important content in the centre.
How to set a Shorts cover
YouTube lets you choose a frame from the Short as its cover in the mobile app, and options keep evolving. A common approach is to put your designed cover as the first frame of the Short so it can be selected.
Design tips for Shorts covers
- Centre the subject; keep text in the middle third.
- Use one or two words, very large.
- Use the same layout across a series so your Shorts grid looks unified.
- High contrast — Shorts covers are often viewed tiny in a grid.
