9:16. YouTube recommends 2160 × 3840 pixels, with a minimum height of 640. ThumbnailMaker downloads a Shorts cover at 1080 × 1920, or 2160 × 3840 in 4K.
On a vertical video, YouTube replaces a 16:9 custom thumbnail with an automatic 4:5 one on the home, Explore and Subscriptions pages. Make the cover vertical from the start.
In YouTube Studio on a computer: custom Shorts thumbnails can't be uploaded from the phone app, which only lets you pick a frame of the video.
The free thumbnail resizer turns any image into a 1080 × 1920 cover and the text editor writes on a Shorts frame, both with no account. Generating a cover takes a plan, from $12 a month; the brief from a link is free with an account.
