YouTube Playlist Length Calculator - Calculate YouTube playlist duration instantly.

I built this tool because I often use YouTube playlists for learning, and I always wanted a quick way to know the total duration of a playlist before watching it. Surprisingly, YouTube doesn’t provide an easy way to calculate this. So I created YouTube Playlist Length, where users can paste any playlist URL and instantly get the total duration, number of videos, average length, and more. During development, I had to solve several challenges: YouTube Data API quota limits – I optimized request batching to reduce API usage while keeping the tool fast. Handling large playlists – Some playlists contain hundreds of videos, so I implemented retry logic and stable pagination handling. Improving mobile experience – Many users check playlists on the go, so I refined the mobile UI for better usability. In the future, I plan to add features like exporting results, visual duration charts, and playlist comparison tools. Any feedback or suggestions are welcome!
