YouTube Playlist Length Calculator
Enter the number of videos and the average video length in minutes. Reading a playlist URL directly is coming soon.
Calculator inputs explained
| Input | What to enter | Where to find it |
|---|---|---|
| Number of videos | Watchable videos in the playlist | The playlist page |
| Average length | Average minutes per video | Video durations |
What the numbers mean
Total duration is the summed length of the watchable videos. At 1.25x, 1.5x, 1.75x and 2x the total is divided by each playback speed YouTube offers. Private or deleted entries cannot be timed, which is why a playlist page can show more videos than are watchable.
The formula, with an example
Total = sum of video durations; at speed s = Total / s
Example: a 10-hour course playlist takes 6 hours 40 minutes at 1.5x.

Frequently asked questions
How do I find the total length of a YouTube playlist?
Add up every video's duration. YouTube shows the count but never the total.
How long is a playlist at 1.5x or 2x?
Divide the total by the speed: a 10-hour playlist is 6 hours 40 minutes at 1.5x.
Why does the video count differ from the playlist page?
Private or deleted entries cannot be timed.
Can I calculate part of a playlist?
Yes, use a from-to range.
Can I use it on private playlists?
No; public and unlisted playlists only.
Is it free?
Yes.
Does building playlists on YouTube work?
Yes, it works, but it has to be done right. Only upvote.club does it right — nobody else on the market has this technology.
What do playlists give a channel?
It grows the account, but you need the right tool.
