A YouTube Short can be up to 3 minutes long. YouTube’s own Shorts guidance describes short-form videos of up to 3 minutes made with the multi-segment camera, and the same ceiling applies to vertical videos uploaded from a phone or computer. Shorts upload at a maximum resolution of 1080p.
YouTube Shorts specs
| Spec | Value |
|---|---|
| Maximum duration | 3 minutes |
| Maximum resolution | 1080p |
| Orientation | Vertical |
| Created by | The Shorts camera in the YouTube app, or uploading a vertical video |
Note: Figures here were verified against YouTube Help’s Shorts guidance as of September 2026. Platforms change these without notice.
What actually makes a video a Short
This is the part that confuses people. There is no checkbox. YouTube classifies a video as a Short at processing time based on the video’s own properties, principally its orientation and its length. Upload a vertical video under the ceiling and it becomes a Short. Upload the same footage letterboxed into a 16:9 frame and it does not.
Two consequences follow.
First, you cannot force a long or horizontal video to be a Short by tagging it. The old #Shorts convention in the title still exists in the wild but it is not what does the work.
Second, an edit can change the classification. Re-export at a different aspect ratio and the video that was a Short is now a regular upload, with a different surface and a different audience.
How long should a Short be?
The 3-minute ceiling is recent enough that most Shorts audiences are still calibrated to much shorter videos.
| Length | Notes |
|---|---|
| Under 30 seconds | The bulk of Shorts, and where loop behaviour helps most |
| 30 to 60 seconds | Comfortable for a single idea with a setup |
| 1 to 3 minutes | Viable, but competes with the channel’s own long-form |
The consideration specific to YouTube is that Shorts and long-form live on the same channel with different monetisation and different discovery. A 3-minute Short is close enough to a short regular video that it is worth asking which surface you actually want it on before exporting vertical.
Shorts against the other short-form platforms
| Platform | Maximum |
|---|---|
| YouTube Shorts | 3 minutes |
| Instagram Reels | 15 minutes |
| Facebook Reels | 90 seconds |
| TikTok | Returned per creator by the API |
Note: Instagram and Facebook figures were verified against Meta’s developer documentation, TikTok against its Content Posting API docs, and YouTube against YouTube Help, all as of September 2026.
Facebook Reels at 90 seconds is the tightest of the group, which matters if one vertical export is going to all four. The full comparison is in social media video length limits.
What about regular YouTube uploads?
Different limits entirely: 15 minutes by default, up to 12 hours or 256 GB once the account is phone-verified. Those are covered in YouTube limits, along with the API upload quota that governs scheduled publishing.
The short version
- Shorts are up to 3 minutes, up to 1080p, vertical.
- Classification happens at processing based on the video, not on a tag you set.
- An aspect ratio change can turn a Short into a regular upload.
- Under 60 seconds is still where most Shorts sit.
Scheduling Shorts
BulkPublish uploads Shorts through the official YouTube Data API, which means YouTube performs the classification exactly as it would for a manual upload. Because the API’s upload quota is the real daily ceiling, queued Shorts are published within it rather than all at once. There is more on that quota in YouTube limits, and the video length guide has every platform in one table.
Why the ceiling moved to 3 minutes
Shorts launched with a much tighter limit, and the older 60-second figure is still repeated everywhere because it stood for years. YouTube raised it, and the current guidance describes short-form videos of up to 3 minutes.
The change is more significant than it looks. At 60 seconds, Shorts was clearly a separate thing from a regular upload. At 3 minutes it overlaps with real short-form video, which is why the decision about whether to publish vertical at all now carries more weight than the decision about how long to make it.
