How to Estimate YouTube Course Watch Time Before You Start
Before committing to a YouTube course, it helps to know how many hours you are signing up for. Whether it is a free coding bootcamp, a design masterclass, or a language course, knowing the total watch time helps you plan your schedule. Wipelist makes this calculation instant.
Step-by-Step Instructions
Find the course playlist URL
Locate the YouTube course or tutorial series you want to take. Navigate to the playlist page (the instructor usually links to it in their channel or video descriptions) and copy the URL from your browser's address bar.
Open Wipelist's Playlist Length Calculator
Go to wipelist.com/playlist-length. This tool is completely free and requires no account or YouTube login. Paste the course playlist URL into the input field.
Click Calculate and read the results
Wipelist calls the YouTube API to fetch the duration of every video in the playlist and adds them up. The result shows the total hours and minutes, plus the estimated duration at 1.25×, 1.5×, and 2× playback speeds.
Plan your learning schedule
Divide the total duration by your available daily study time to estimate how many days or weeks the course will take. For example, a 20-hour course watched at 1.5× playback (≈13 hours) spread over 1 hour of daily study would take about 2 weeks.

Does the calculator work for playlists with hundreds of videos?
Yes. Wipelist uses the YouTube API with pagination to fetch all videos regardless of playlist length. A 200-video course playlist takes only a few seconds to calculate.
Can I see which videos in the course are the longest?
The free calculator shows the total and per-speed estimates. Signed-in Wipelist users who have connected their YouTube account can see the full video list with individual durations.
What if some course videos are unavailable?
Unavailable videos are excluded from the calculation because their duration cannot be retrieved. The result shows only the videos that are currently watchable.
