desktop. Or to add a custom thumbnail to an existing Short, open YouTube Studio on desktop, go to the content tab, select Shorts, click the details, the pencil icon, next to the Short you want to edit. Under the thumbnail section,

same way you've previously been able to do for your long-form on desktop. And if frame, you can still do that on mobile. A few things for creators to keep in mind. While the aspect ratio for Shorts is 9x16, the sweet spot for Shorts
thumbnails across devices and presentations is closer to 3x2. So, keep anything important just away from the edges. Also, fully custom channels in the YouTube Partner Program. YouTube will be expanding access over
time though, so stay tuned for future updates. And yeah, there's no AB testing for Shorts thumbnails, at least for now, and it's desktop only, also at least for mobile, and you still want a fully custom thumbnail, you just have to go to

YouTube that the way Shorts look on the homepage, and maybe most importantly, on the home and Shorts tab of the channel page to brands is really important and there really should be a way to set a fully custom thumbnail. So, now there
questions in the comments and keep it real.
