YouTube Shorts size and length

Current Shorts spec table

Which uploads qualify as Shorts?

For standard YouTube channels, videos uploaded on or after October 15, 2024 are categorized as Shorts when they are square or vertical and no longer than three minutes. Older uploads keep their previous classification. Official Artist Channels and channels linked to a music Content Owner use a later cutoff: December 8, 2025.

These dates matter when you compare an old upload with a new one. Two files with the same shape and duration can be classified differently because they were uploaded under different rules.

The over-one-minute copyright caveat

YouTube says a Short longer than one minute with an active third-party copyright claim of any type will be blocked globally. It will not be playable, recommended, or eligible for monetization. YouTube says the block itself does not add a channel penalty, but the video is unavailable until the claim is resolved or the content changes.

That is not a loophole or a fair-use decision. A copyright claim and the underlying legal rights are separate issues. If a Short uses third-party material, check the rights and current platform policy before upload.

A clean export checklist

1. Set the canvas to 1080 × 1920. Keep the project vertical from the first edit.
2. Use the source frame rate. Avoid inventing extra frames during export.
3. Keep important text away from edges. Preview the final file in a phone-shaped viewport.
4. Remove baked-in black bars. Let YouTube fit the vertical or square file.
5. Listen once on a phone speaker. Speech should remain understandable at low volume.
6. Watch the exported file, not only the editor timeline. Check the first frame, last frame, captions, and audio sync.
7. Confirm the duration. Keep it at or below three minutes if it must be a Short.

Common format mistakes

Adding black bars to make a horizontal clip vertical

A better approach is to reframe the subject for a vertical canvas or use intentional design space. YouTube's upload guidance says not to add black bars to vertical video because its player handles the display.

Assuming every Short must be exactly 60 seconds

The current maximum is three minutes for eligible uploads, not 60 seconds. That does not mean every idea should use all three minutes. Stop when the promise is delivered.

Treating 1080 × 1920 as the only eligible shape

It is the cleanest full-screen production canvas, but YouTube's classification rule also includes square video. Keep the eligibility rule separate from the design recommendation.

The bottom line

Export at 1080 × 1920 for a conventional full-screen Short, keep the file square or vertical and no longer than three minutes, and preview the real export on a phone. If the Short is longer than one minute, resolve any active third-party copyright claim before expecting it to be playable.
