How to sort a lecture playlist by length for study playlist planners in 2026

Q: Which browsers work with YTSort?

The add-on needs Chrome or Edge. The script works in any browser, including Firefox, once you add a script manager such as Tampermonkey, Violentmonkey or Greasemonkey, a small add-on that runs scripts for you. It can also be run from a bookmark.

Find the length of each lecture, order the playlist from shortest to longest, and start at the top. You can do it by hand on paper or in a spreadsheet.

What you need before you start

Sorting a lecture playlist by length takes only a few things.

A playlist you own. Reordering a playlist in place only works on one that belongs to your account. For someone else's playlist, you can copy the lectures into your own first or work from a written list.
The length of each lecture. YouTube shows it on each thumbnail. You need it to rank the lectures.
A reason for going short first. It might be to fit a free half hour between classes or to start with the shorter recap lectures. Know which, because it decides what you do with the long ones.
A place to keep the order. The playlist itself, a paper list or a spreadsheet all work. What matters is that the order lives in one place.
A web browser. Only needed if you want a tool to do the sorting. Add the tool to your browser once, before you start, following its own instructions.

Set aside a short block before you begin a study session. Sorting while you are already revising tends to break your flow.

Step by step

These steps work with any tool, including a pen and a sheet of paper.

Open the playlist you want to sort. Make sure you can access the playlist before choosing a way to put shorter lectures first.
List every lecture with its length. Write the title and the time shown on the thumbnail. Do not sort yet.
Mark lectures that must stay in order. Some courses build on earlier lectures. If lecture two needs lecture one, keep those two together.
Rank the rest from shortest to longest. Put the shortest at the top.
Decide what happens to the very long lectures. You can leave them at the end or schedule them for a longer study block.
Check the order before you commit. Read the new list once from top to bottom and look for lectures that now sit in a confusing place.
Apply the order. Reorder the playlist by hand, or use a tool that does it for you.
Watch from the top. Start with the first lecture and move down the list.
Keep notes as you go. Short lectures pass quickly, so a line or two per lecture helps the ideas stick.
Review after the first few sessions. If the order is not helping you learn, change it.

Tools that can do it

You do not need software for this. Here are options to consider.

Paper list or sticky note. You write each title and length and rank them by hand. Nothing is published here about price or limits because it depends on what you already own.

A spreadsheet. A column for the title, a column for length and a sort on the length column gives you a shortest-first list. Check how it behaves on your phone if you plan to use it away from your desk. Facts about specific spreadsheet apps are not provided here, so check their own pages for limits and cost.

YTSort. YTSort is made by the team that publishes this site. YTSort is one option. Reorders a YouTube playlist you own by video length, shortest or longest first. ^[1]

You can get YTSort through a bookmark, a browser script, or a Chrome Web Store extension. ^[1] The extension needs Chrome or Edge, and the script version works in any browser, including Firefox, with Tampermonkey, Violentmonkey or Greasemonkey installed. ^[1] After sorting, it reads the playlist back from YouTube and re-applies any moves that did not stick. ^[1] It sorts the full playlist, not just the lectures loaded on screen. ^[1]

Common mistakes to avoid

Sorting a course that builds lecture by lecture. If later lectures rely on earlier ones, a pure shortest-first order can leave you confused. Keep dependent lectures together.

Trusting the order without a look. Read the new order once before you start. A quick check catches lectures that ended up in an odd spot.

Forgetting the long lectures. Moving them to the end is fine, but give them a day to be watched or they never get done.

Trying to reorder a playlist that is not yours. Check who owns it first. If it is not yours, copy the lectures into your own playlist or keep a written list.

Watching without notes. Short lectures go by fast, so notes can help you keep track of what you watched.

Never reviewing the order. If the order is not working for your study time, change the approach instead of sticking with it.

Things to check before you choose

Before you pick a way to sort, check a few details on the tool's own page. Confirm that the playlist you plan to sort belongs to the account you will use. If a course keeps lectures in a fixed order, check that the tool can leave those in place. When a paper list or spreadsheet is your choice, check how your own files handle lengths in minutes. For a browser tool, check that it works with the browser you use. YTSort's extension needs Chrome or Edge, and its script version works in other browsers once a userscript add-on is installed. ^[1]

Frequently asked questions

How to put the shortest lectures first in a YouTube playlist?

List each lecture with its length, rank them from shortest to longest, then apply that order to the playlist by hand. If some lectures build on earlier ones, keep those in order rather than splitting them.

Can the new playlist order be checked before it is applied?

With YTSort, yes. It shows the before and after order so you can check it before applying. ^[1] With a paper list or spreadsheet, you see the order as you write it, so read it through once before you start watching.

Which browsers work with YTSort?

The add-on needs Chrome or Edge. ^[1] The script works in any browser, including Firefox, once you add a script manager such as Tampermonkey, Violentmonkey or Greasemonkey, a small add-on that runs scripts for you. ^[1] It can also be run from a bookmark. ^[1]

Can YTSort sort only lectures within a certain length?

Yes. YTSort can sort only lectures within a length range you set and move the rest to the end. ^[1] It also shows the total, average, shortest and longest lecture duration for the playlist, ^[1] and it can export the position, title, duration and URL of every lecture to a CSV file. ^[1]

Should study playlist planners always watch the shortest lectures first?

Not always. If a course builds lecture by lecture, keep dependent lectures in order. Shortest first can suit a free half hour between classes. For long courses, review the order after a few sessions and change it if needed.

YTSort is free; all install options include the same features. ^[1]
