Paste one video length per line (like 5:32 or 1:02:15) and instantly get the total runtime for the whole playlist.
Paste one video length per line to calculate the total.
The Playlist Duration Calculator adds up a list of individual video lengths to find the total runtime of a full playlist. It's built for creators planning a playlist's total watch time, viewers deciding whether a playlist fits into a commute or workout, and anyone who's ever wanted to know how long a full course or series actually takes to watch without manually adding up dozens of individual timestamps. Paste one video length per line — in MM:SS, HH:MM:SS, or plain seconds, straight from YouTube or typed by hand — and the tool instantly totals them, along with the video count and average length per video. Formats can even be mixed within the same list, since each line is parsed independently.
MM:SS (like 5:32), HH:MM:SS (like 1:02:15), or a plain number of seconds — you can mix formats across lines.
Yes — paste one per line exactly as YouTube displays them (e.g. 12:04), and any extra text on the line is ignored as long as a time value is present.
This tool only does math on the lengths you paste in — it doesn't look anything up, so it works the same regardless of a video's visibility.
The total combined runtime, how many valid video lengths were counted, the average length per video, and the total in raw seconds — useful if you need the exact number for another calculation.
It's simply skipped and not counted toward the total or the video count, so a stray blank line or header text in your pasted list won't break the calculation.
Paste one video length per line and this youtube playlist watch time calculator will add up video lengths automatically into a total playlist runtime calculator result.
Yes — it accepts MM:SS, HH:MM:SS, or plain seconds in the same list, so you can paste lengths straight from YouTube without reformatting them.
