YouTube Playlist Length - Duration Display

Tracking since Apr 16, 2026.

Changelog

• Apr 16, 2026
  description

  A Lightweight extension that displays the length of the YouTube playlist you are viewing or watching. It works on both the Playlist viewing page, and the watching page, blending in with YouTube's existing stats.
  
  The display can be customized to your preference - these options are accessible from the extension's popup (as shown in the video above). Please leave your feedback and suggestions for any extra options you would like!
  
  For playlists longer than 100 videos, you will need to scroll to the final video on the Playlist view page for a full calculation. Unfortunately this will not work on the watch page as YouTube only loads up to 400 videos.
  
  Hover on the length displayed to view how many videos have been counted.
  
  If you like the extension please submit a review!
  
  Future plans:
  - More complex displays, showing progress through playlist in a more visual way etc.
  - More options (leave suggestions in your reviews!)
  - Display on the YouTube mini player.
  
  Known Bugs:
  - The duration display sometimes 'flashes' a few times when going into playlist view.
  
  Please report any issues via my email listed below in the Details section!
