Shorts are vertical, so their thumbnails are vertical too. Here are the exact numbers and how they differ from a standard YouTube video.
YouTube Shorts thumbnails are 1080 × 1920 pixels with a 9:16 vertical aspect ratio. This is the size YouTube recommends for custom thumbnails on Shorts, and it matches the portrait shape of the Shorts feed — where the vast majority of Shorts are watched on a phone, held upright. A 1080×1920 image fills that feed edge to edge with nothing cut off.
It's a common mistake to assume a Shorts thumbnail uses the same dimensions as a regular YouTube video. It doesn't. Standard YouTube video thumbnails are 1280 × 720 pixels at a 16:9 horizontal aspect ratio. Shorts are vertical, so their thumbnails are vertical too — almost twice as tall as they are wide. If you upload a horizontal 1280×720 image as a Shorts thumbnail, YouTube crops the left and right edges, and your subject can easily end up sliced in half. Starting from the correct 1080×1920 canvas avoids that entirely.
Three thumbnail sizes you'll meet on YouTube, side by side.
| Thumbnail type | Dimensions | Aspect ratio | Where it appears |
|---|---|---|---|
| Shorts Vertical |
1080 × 1920 px | 9:16 (portrait) | Shorts feed on mobile / desktop |
| Standard video Horizontal |
1280 × 720 px | 16:9 (landscape) | Watch page, search, related, home |
| Channel avatar | 800 × 800 px | 1:1 (square) | Channel page, comments |
The reason for two different sizes is the reason for two different viewing contexts. Regular videos are watched on watch pages, in search results and next to related videos — all horizontal layouts, so the 1280×720 / 16:9 thumbnail fits. Shorts are watched in a full-screen, swipe-up vertical feed, so the thumbnail has to be 1080×1920 / 9:16 to fill the screen. One channel can use both sizes: every long-form video gets a 1280×720 thumbnail, and every Short gets a 1080×1920 one.
YouTube's hard requirements vs. what actually looks good on a phone.
YouTube's documented minimum for any custom thumbnail is 640×360 pixels, but for Shorts that floor is not worth using. A 640×360 image stretched across a 1080-wide phone screen looks visibly soft, and the platform will upscale it. Always export at the full 1080×1920. Keep the file under 2 MB — YouTube rejects anything larger — and prefer PNG when your thumbnail has crisp text or a logo, since JPG compression blurs edges.

Why everyone suddenly cares about the Shorts thumbnail size.
For a long time, Shorts did not really have custom thumbnails at all — YouTube picked a frame from the video for you, and that was the thumbnail. That changed in late 2024, when YouTube began rolling out the ability to upload a real, custom vertical thumbnail for Shorts in YouTube Studio. Once creators could finally control the image, the exact YouTube Shorts thumbnail size — 1080×1920, 9:16 — became something worth knowing, and searches for it climbed sharply.
That shift is the whole reason this page exists. If you can upload a custom thumbnail, you want it to be the right shape. Reusing a regular 1280×720 thumbnail means handing YouTube a horizontal image and trusting its auto-crop; making a purpose-built 1080×1920 cover means you decide exactly what stays in frame. The tool above does the cropping for you and adds room for a title, which matters because a Shorts thumbnail with bold, readable text consistently out-clicks a plain frame.
A few design notes that pair well with the 1080×1920 canvas: keep the most important subject and any text in the center vertical third of the image, where nothing overlaps the UI; use large, high-contrast type (the mask slider in the tool darkens the photo behind your text so it stays legible); and avoid putting critical detail near the very top or bottom, where channel names and action buttons sit. Export as PNG when there's text, keep it under 2 MB, and you have a Shorts thumbnail at the exact size YouTube wants.
