How to Calculate YouTube Playlist Total Watch Time
YouTube shows how many videos are in a playlist but does not display the total watch time. Whether you are planning a study marathon, estimating how long an online course takes to finish, or simply curious, knowing the total duration is useful. This guide covers the manual approach and the fastest automated method.
Step-by-Step Instructions
Count videos and estimate manually
Open the playlist on YouTube. Note the total number of videos listed (e.g., '47 videos'). If you know the average video length for that playlist, multiply to get a rough estimate. For a playlist of 47 videos averaging 15 minutes each, that is roughly 11 hours and 45 minutes.
Use the YouTube Studio duration view
If you own the playlist, you can open YouTube Studio, navigate to 'Playlists', and in some regions YouTube shows a total duration. This is not always accurate and does not work for playlists you do not own.
Use Wipelist's free Playlist Length Calculator
Go to wipelist.com/playlist-length and paste the playlist URL. Wipelist fetches the duration of every video using the YouTube API and adds them up, giving you the exact total in hours, minutes, and seconds — including unavailable-video exclusions. It works for any public or unlisted YouTube or YouTube Music playlist.
Filter results by speed
Wipelist's calculator also shows how long the playlist takes at 1.25×, 1.5×, and 2× playback speed — useful when you want to finish a course faster.

Does Wipelist's playlist length calculator work for private playlists?
The free calculator works for public and unlisted playlists. To calculate the length of your own private playlists, sign up for a Wipelist account and connect your YouTube account.
Why does the total duration differ from what I expect?
Unavailable or deleted videos are excluded from the calculation because YouTube does not provide their duration. Live streams without a recorded duration may also be skipped.
Can I calculate a YouTube Music playlist length?
Yes. Wipelist supports both YouTube and YouTube Music playlist URLs. Paste the full playlist URL and the calculator handles the rest.
