YouTube Shorts length and size in 2026: what makes a video a Short

A YouTube Short is any video on a standard channel that is vertical or square and at most three minutes long. There is no separate Shorts upload: YouTube decides from the aspect ratio and length. Everything else — file size, title and description limits — follows the normal YouTube rules.

What makes a video a Short

YouTube's help center defines it: videos uploaded to a standard channel on or after October 15, 2024 are Shorts if they have a "square or vertical aspect ratio up to three minutes in length". For Official Artist Channels the three-minute rule applies to uploads since December 8, 2025. Videos uploaded before those dates kept their old classification.

This works in both directions. A vertical clip you meant as a normal video becomes a Short if it's under three minutes; YouTube's advice is to use a wider 16:9 ratio for videos you don't want classified as Shorts.

File limits

Shorts use YouTube's general upload limits: up to 256 GB or 12 hours, whichever is less. In practice a Short is a few hundred megabytes at most. Export it as 1080×1920 H.264 MP4; the same file works on TikTok and Reels, as shown in our social media video specs overview.

The copyright rule for Shorts longer than one minute

When YouTube extended Shorts to three minutes, it added a rule that matters for anyone using music or clips: a Short over one minute with an "active copyright claim of any type" is blocked globally. It can't be played, recommended or monetized until the claim is resolved; YouTube says there are no penalties for the channel. Shorts under one minute aren't affected.

Title, description and tags

The description limit is counted in bytes. Plain English letters are one byte each, accented letters such as é or ő are two, and most emoji are four. A description in Hungarian, German or with a row of emoji hits the limit well before 5,000 visible characters. The character limits guide compares this with the other networks.

Hashtags on Shorts

YouTube's hashtag policy has two numbers worth knowing:

• Of the hashtags in your description, up to three that YouTube considers most engaging appear above the title.

• If a video has more than 60 hashtags, YouTube ignores every one of them.

YouTube also warns that hashtags not directly related to the video "may result in the removal of your video". A short list of specific tags does more than a long generic one. See hashtag limits by platform for how this compares with Instagram's 30 and Threads' tighter text limit.

Scheduling a Short

Through YouTube's API, a scheduled video is uploaded as private with a publishAt time. YouTube's rules for that field: it can only be set on a private video that has never been published, and a time in the past publishes the video immediately. Scheduling tools that publish at the chosen time from their own queue skip this field and upload at the scheduled moment instead; either way the Short goes public when you planned.

Shorts and monetization in 2027

YouTube announced on August 10, 2026 that from February 1, 2027, channels need 10 million qualified Shorts views in the last 90 days to share in Shorts ad and subscription revenue, and new Partner Program applicants need 8,000 watch hours in 365 days or 20 million Shorts views in 90 days. Existing members stay in the program. What Shorts pay per view today is in how much YouTube pays per view.

Before you schedule a Short

• Vertical or square, at most 3:00 — or under 1:00 if it contains third-party music or footage.

• 1080×1920 H.264 MP4.

• Title under 100 characters, description under 5,000 bytes.

• Two or three specific hashtags at the end of the description.

• Nothing important in the bottom sixth or the right edge, where YouTube's title and buttons sit — see safe zones.

When Uplonic publishes to YouTube, the title is trimmed to 100 characters and the description to 5,000 bytes — counted the way YouTube counts — and at most 15 hashtags are kept, so the description stays readable.
