If I recall correctly, there used to be a feature of YouTube which showed the total length of all the videos in a playlist, combined. This was very useful as it enabled you to see the length of a game play-through, etc. A Google search suggests this feature has been removed and no immediate solution presents itself, but is there a way to view the total length without having to add it up manually?

    2020 update YouTube Playlist Analyzer as per the developer's note, ..."is no longer maintained by the developer". Alternatives (as extensions for Google Chrome) can be found in this answer – marikamitsos Jan 29 at 20:44

I made an app to do exactly that, hosted on Heroku: YouTube Playlist Length. You can also find the app repository here.

Note: it can find the total length of a playlist that has up to 500 videos. If it has more than 500 videos, it shows the total length of the first 500 videos.

since RedDragon's web tool returneed me an "Internal Server Error" and apparently is not maintained I made a quick few-liner that returns duration, which you can paste into devtools:

var minutes = [... document.querySelectorAll("ytd-thumbnail-overlay-time-status-renderer > span")]
.reduce((acc, dur) => {
    dur = dur.textContent.trim().split(':');
    return acc + parseInt(dur[0]) * 60 + parseInt(dur[1]);
}, 0) / 60;
alert(Math.floor(minutes / 60) + " hours " + minutes % 60 + " minutes.");

or instead of pasting code into devtools you can install and use a userscript I just made, which runs the code above when you press alt + shift + u on a playlist page.
