YouTube Shorts Size and Aspect Ratio: 1080×1920 (9:16)

Short answer

Make YouTube Shorts 1080×1920 pixels, a 9:16 vertical frame. YouTube also accepts square (1:1) videos as Shorts, but a video wider than square, such as 16:9, is uploaded as a regular video instead.

SettingUse this
Resolution1080×1920 pixels
Aspect ratio9:16 (vertical)
Also accepted as a Short1:1 (square), or anything taller than square
Not a Short16:9 or any frame wider than it is tall
LengthUp to 3 minutes
FormatMP4 with H.264 video and AAC audio is the safe choice

1080×1920 fills a phone screen with no black bars, and it is the same size TikTok and Instagram Reels recommend, so one export works everywhere.

What happens with a horizontal video

YouTube only treats square or vertical videos as Shorts. Upload a 16:9 clip and it becomes a regular video, even if it is 20 seconds long. If you filmed horizontally, crop it to 9:16 in your editor before uploading, keeping the subject in the middle of the frame.

Does resolution matter?

YouTube accepts lower resolutions, but 1080×1920 looks sharp on every phone and gives YouTube a good source to compress. Filming in 4K vertical is fine too; just keep the 9:16 shape. Avoid exporting at 720×1280 if you can, because text and faces get soft after compression.

Leave room for the buttons

The Shorts player puts the title, channel name and buttons over the bottom and right side of your video. Keep text and faces away from those edges so nothing important is covered.

Check a file before you upload
