How Long Should a YouTube Video Be?
As long as its format needs, and no longer. When we measured the 2,859 latest long-form videos of the most-subscribed YouTube channels, the median ran 12.3 minutes, but music channels ran 3.5 and education channels 39.9. Shorts can now run up to 3 minutes, yet 82% of big channels' Shorts still last a minute or less.
So there is no single right length to aim for. The popular "the average YouTube video is 11.7 minutes" figure is a measurement of all public videos at the end of 2018; our study traces where it came from. What you can plan around is what channels in your format actually post, and the few hard limits YouTube sets.
What the Biggest Channels in Each Format Post
Long-form videos on the biggest channels split into two camps rather than clustering around an average: 35 channels whose latest videos run a median under 5 minutes, mostly music, and 38 whose videos run over 20 minutes. Only 24 sit in between. Here is the median length by kind of channel, for every category with three or more channels on the list:
| Kind of channel | Channels | Median length of their latest videos |
|---|---|---|
| Music | 25 | 3.5 min |
| Comedy | 3 | 5.7 min |
| Entertainment | 42 | 20.2 min |
| Film | 4 | 24.5 min |
| Gaming | 7 | 26.2 min |
| People | 5 | 26.5 min |
| Education | 5 | 39.9 min |
Read the row closest to what you make. A lesson or explainer has room to run long, which is why education channels sit at the top and why course creators can publish 30-minute videos without apology. A song, a sketch or a recap runs short because the format does, not because viewers punish length.
The Length Rules YouTube Actually Sets
YouTube rewards no length for its own sake. Its description of how recommendations work talks about relevant, satisfying viewing, measured through what people watch, like and say in satisfaction surveys. Padding a video to hit a target length works against exactly that.
The limits that do exist, checked on YouTube Help on November 11, 2026:
- Shorts run up to 3 minutes. A square or vertical video up to three minutes is a Short. YouTube raised the cap to three minutes on October 15, 2024, and its three-minute Shorts page covers which uploads count.
- Mid-roll ads start at 8 minutes. On monetized videos 8 minutes or longer, you can place ads in the middle of the video.
- Chapters need three timestamps. The list must start at 00:00, have at least three timestamps, and each chapter must run at least 10 seconds.
- Uploads over 15 minutes need a verified account. After verification, the limit is 256 GB or 12 hours, whichever comes first.
How Long Should YouTube Shorts Be?
Most big channels don't use the extra time. Across the 574 latest Shorts we checked from the same channels, the median ran 40 seconds and half ran between about 25 and 58 seconds. Only 18% ran over a minute, and 13 of 574 over two. Education channels made the longest Shorts (a median 60.5 seconds) and comedy channels the shortest (28.5).
Treat 3 minutes as a ceiling. The fastest way to find a Short is to cut the strongest 30 to 60 seconds out of a long video you already made, which our guide to repurposing long-form video into Shorts walks through.
How Long Should My First YouTube Video Be?
Long enough to deliver what the title promises, and short enough that you finish it and publish. Pick the format first, look up its row in the table above, and script to that length rather than guessing: our free script length calculator turns a word count into minutes at your speaking pace. The 8-minute mid-roll line only matters once a channel is monetized, so it is no reason to stretch a first video.
A Length Check Before You Publish
- Name the format. Find the closest row in the table and note its median.
- Script to time. Count the words and convert them to minutes before you film.
- Cut what doesn't move the payoff. Every tangent, repeat and slow intro comes out; our post on retention editing shows how the audience retention graph points at them.
- Add chapters to long videos. Three or more timestamps, starting at 00:00.
- Place mid-rolls at natural breaks if the video runs 8 minutes or more and the channel is monetized.
- Cut a Short from the strongest 30 to 60 seconds.

The Bottom Line
There is no ideal YouTube length, only the length your format needs: a median 12.3 minutes on the biggest channels, from 3.5 for music to 39.9 for education, and 40 seconds for their Shorts. Plan around your format's peers and YouTube's few hard limits (3-minute Shorts, mid-rolls from 8 minutes), then cut until every minute earns its place.
