YouTube playlist length calculator
Get a playlist's total run time from your video count and average length.
Enter your video count and average length to get the total watch time — handy for course and binge planning.
YouTube tells you how many videos are in a playlist, but never the combined run time — which is exactly what you need when you're deciding whether to start a course, a tutorial series or a long binge. This calculator fills that gap: enter the number of videos and their average length, and it returns the total time instantly, plus how long the playlist runs at 1.5× and 2× speed.
It works from an average because typing every single duration is tedious. If your videos vary a lot, take the length of a few representative videos, average them by eye, and you'll get a total that's accurate to within a few minutes — more than close enough for planning.
Who this is for
Viewers use it to budget their time before committing to a series — a 40-video playlist at 12 minutes each is eight hours, which is a very different decision from a two-hour crash course. Learners planning a study schedule can split the total across days. And creators building a course or a structured series can size each module and keep the pacing consistent.
For creators: make your playlists work harder
Playlists are one of the best tools you have for growing watch time, because they auto-play the next video and keep a session going. A well-ordered playlist can meaningfully lift the average session length on your channel, which the algorithm rewards with more reach. Model the earnings that watch time can produce with our YouTube money calculator.
If you want more eyes on a new series, real YouTube views from active accounts give the first videos in a playlist the early traction that helps the whole series get recommended.
Frequently asked questions
How do I find the total length of a YouTube playlist?
Multiply the number of videos by their average length. This tool does that instantly and also shows the time at 1.5× and 2× playback speed.
Why calculate a playlist's length?
It's useful for planning a course binge, a study session, or a road-trip watch list — and for creators sizing up how long a series or module runs.
Does YouTube show a playlist's total time?
Not directly. YouTube lists the video count but not the combined run time, so a quick calculation like this fills the gap.
How do I watch a long playlist faster?
Use YouTube's playback speed controls — this calculator shows the total at 1.5× and 2×, which can cut a 10-hour playlist down to 5 hours without missing the content.
