About Us

We built a focused tool to sum public playlist durations and help you plan watch time.

The YouTube Playlist Length Calculator helps students, creators, and viewers estimate how long a public YouTube playlist runs end to end. You paste a playlist or watch URL, optionally narrow the range, and get totals backed by the same duration data YouTube exposes through its API.

This site is independent and not affiliated with YouTube or Google. Trademarks belong to their respective owners.

What you can do here

Sum durations for all videos the API returns for a public playlist.
Compare wall-clock time at different playback speeds after you calculate.
Browse per-video lengths in a simple table with links to watch on YouTube.
