The Missing Feature on YouTube: Total Playlist Duration

YouTube is the world's largest repository of educational material, from complete computer science degree tracks to full-length audiobooks and masterclasses. Yet despite decades of platform updates, YouTube still only shows you the number of videos in a playlist—for example, "38 videos"—without disclosing the cumulative running time.

A 38-video playlist could consist of three-minute music clips (under 2 hours total) or two-hour university symposiums (over 76 hours total). Guessing can derail your entire study schedule. Here is how you can find the exact length down to the second.

Method 1: Using CheckPlaylistLength.com on Desktop (Mac & Windows)

Open YouTube: Navigate to YouTube.com and open the playlist you want to measure.
Copy the URL: Copy the URL directly from your browser's address bar (e.g., https://www.youtube.com/playlist?list=PL...) or click the Share button beneath the playlist title and click Copy.
Paste into the Calculator: Head to CheckPlaylistLength.com and paste your link into the primary search bar.
Click Calculate: Press Enter or click the Calculate button. Within seconds, you will receive the full duration, video count, shortest and longest videos, average video length, and watch time at 1.25x, 1.5x, 1.75x, and 2.0x speeds.

Pro Tip: You don't even need the pure playlist URL. You can paste any individual video link that is playing inside a playlist (links containing &list=...), and our system will automatically extract and analyze the entire playlist for you!

Method 2: How to Check Playlist Length on Mobile (iOS & Android)

Checking playlist lengths on your smartphone is just as seamless:

Launch the YouTube App on your iPhone, iPad, or Android phone.
Open the playlist you want to inspect.
Tap the Share icon (the curved arrow near the playlist thumbnail).
Tap Copy link from the share menu.
Open your mobile browser (Safari, Chrome, or Firefox), navigate to checkplaylistlength.com, paste the link, and tap Calculate.

What If a Playlist Contains Private or Deleted Videos?

Public YouTube playlists occasionally contain videos marked as "Private" or "Deleted by uploader." YouTube locks the metadata of private videos, meaning third-party tools cannot inspect their running times.

Our parser transparently flags how many public videos were analyzed versus hidden items, calculating the 100% accurate duration of all playable content so you aren't surprised by missing time.
