YouTube playlist duration guide

How to Calculate YouTube Playlist Length

YouTube does not always show the total runtime of a playlist in a way that helps you plan. YT Slice calculates the total length of a playlist and can also measure only a selected range of videos.

Quick Answer

To calculate YouTube playlist length, copy the playlist URL, paste it into YT Slice, and choose whether to calculate the full playlist or a custom range. The result shows total watch time, average video length, and playback speed estimates.

Open the calculator

Steps

  1. 1. Copy the playlist URL. Use a public YouTube playlist link that contains a playlist ID after list=.
  2. 2. Paste it into YT Slice. The calculator fetches the playlist videos and reads each video duration.
  3. 3. Choose a range if needed. Leave the full playlist option on, or enter start and end video numbers.
  4. 4. Check the watch time. Review the total duration and compare times at common playback speeds.

When a Range Calculator Helps

Range selection is useful for long playlists, online courses, study plans, and playlists where you have already watched the first set of videos. Instead of calculating the whole playlist again, you can measure only videos 20 to 45 or any other section.
