How to see how long a YouTube playlist is

Updated · tested in Chrome

Short answer

YouTube shows how many videos a playlist has, not the total running time. Turn on “Playlist duration” in ytbud for YouTube: playlist pages and the playlist panel on watch pages show “Total 3:12:40 · 1:05:12 left”.

Add to Chrome — it’s free
Playlist duration, recorded on YouTube with ytbud.

Without an extension

Add up the durations under each thumbnail, or paste the playlist link into a playlist length calculator site.

With ytbud, step by step

  1. Add ytbud to Chrome and turn on Playlist duration in Tools → Buttons under the video.
  2. Open any playlist page, or a video playing from a playlist.
  3. The total and the time left appear next to the playlist title.

Good to know

Honest about long lists
YouTube loads up to 200 items at a time. Items not loaded yet show as “+N unknown” instead of being guessed.
Finish sooner
At 1.5× with “Real time left” on, you see the time remaining at your speed.

Questions

Does it count the videos I’ve already watched?

The time left counts from the video you’re on to the end of the list.
