Frequently asked questions
Quick answers about the shorts cover maker tool.
What size is a Shorts thumbnail?
1080 × 1920 (9:16). YouTube crops it to a 3:4-ish tile in the channel grid, so keep the title in the middle.
Can I upload a custom Shorts thumbnail?
Yes, in YouTube Studio on desktop, or by choosing a frame in the app; the downloaded cover works for both.
