YouTube Playlist Length Calculator
Get the total runtime of any public playlist — and how long it takes at 1.25×, 1.5× or 2× speed.
A channel ID (UC…) works too: it calculates every video that channel has published.

How it works
- 01
Paste the playlist
A playlist URL, a bare PL… identifier, or a UC… channel ID to measure an entire channel.
- 02
Pick a speed
The runtime recalculates instantly. At 1.5× a twelve-hour course becomes eight.
- 03
Set a daily pace
Enter how many minutes a day you can give it and you get a finish date instead of an abstract total.
What people use it for
Before starting a course
A tutorial series that looks like an afternoon often turns out to be twenty hours. Better to know before episode one.
Sizing a channel
Paste a channel ID and you get the total runtime of everything it has ever published — useful when studying a competitor's output.
Planning a watch schedule
The daily pace turns a total into a date, which is the number you actually plan around.
Frequently asked questions
Does it work on private playlists?+
No. The playlist has to be public or unlisted — a private playlist is invisible to everyone but its owner, and no tool can read it.
Why is the video count lower than what YouTube shows?+
Because private and deleted videos stay in a playlist as placeholders. YouTube counts them in the total; they have no duration, so we cannot. We show them separately rather than silently producing a runtime that is too short.
Is there a limit on playlist size?+
We read up to 500 videos. Beyond that the result is marked as partial rather than presented as complete. That covers essentially every course, series or album playlist.
Can I calculate the length of an entire channel?+
Yes — paste the channel ID (the UC… string) instead of a playlist. Every channel has a hidden playlist containing all of its uploads, and that is what gets measured.
Why does a mix playlist return nothing?+
Mixes (identifiers starting with RD) are generated on the fly for each viewer and have no fixed contents. There is no stable list to measure.
Does the speed setting change the actual videos?+
No, it only divides the runtime. YouTube offers 0.25× to 2× in its own player; the calculator mirrors the useful range so you can plan around how you actually watch.
