Playlist Length Calculator

What this calculator does

It adds up video lengths and shows how long the whole set takes at normal and faster playback speeds. It is useful for YouTube playlists, online courses, lecture series and any binge you want to plan.

Two ways to use it

• Exact: paste each video's length, one per line, using minutes and seconds (12:30), hours (1:05:10) or just minutes (45).
• Quick: enter the number of videos and an average length when you do not have every length.

How the maths works

Total time = sum of all video lengths. Time at speed S = total ÷ S. Days to finish = time at your speed ÷ the minutes you can watch per day, rounded up. Watching at 1.5x turns a 10-hour playlist into about 6 hours and 40 minutes.

Is faster always better?

Faster playback saves time, but dense or unfamiliar material is easier to absorb at normal speed. Many learners use 1.25x to 1.5x for review and slow down for new concepts. Pausing to take notes adds time that this tool does not count.

For creators

Planning a series? Use the total to decide how many episodes viewers can finish in a week. Add chapters to long videos with the timestamp generator.

Frequently asked questions

Can it read a YouTube playlist link?

No. It works from the lengths you enter, which keeps it private and free of API limits. Copy the durations from the playlist, or use a count and an average.

What formats can I paste?

Minutes and seconds like 12:30, hours like 1:05:10, or a plain number for minutes.

Does it include breaks?

No. It counts only video time. Add time for notes and pauses yourself.
