Course builders can put the shortest lessons first by measuring each lesson, ranking the playlist from shortest to longest and checking the order before learners see it. You can do it by hand on paper or in a spreadsheet, or with a tool that sorts a YouTube playlist for you.

What you need before you start

Organizing a learning playlist by shortest lessons first takes only a few things.

A playlist you own. Reordering a playlist in place only works on one that belongs to your account. For a playlist someone else made, you can copy the lessons into your own first or work from a written list.
The length of each lesson. YouTube shows the length on each thumbnail. You need it to rank the lessons.
A reason for going short first. It might be to fit a free half hour or to build momentum at the start of a course. Know which, because it decides what you do with the long lessons.
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. You only need one if you want a tool to do the sorting. Set it up once before you start, following the tool's own instructions.

Set aside a short block before you work on a course module. Sorting while you are already teaching or reviewing 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 organize. Make sure you can see every lesson before you choose how to reorder it.
List every lesson with its length. Write the title and the time shown on the thumbnail. Do not reorder yet.
Mark lessons that must stay in order. Many courses build on earlier lessons. If lesson two needs lesson one, keep those two together.
Rank the rest from shortest to longest. Put the shortest lesson at the top.
Decide what happens to the longest lessons. You can leave them at the end or give them a longer free block.
Check the order before you commit. Read the new list once from top to bottom and look for lessons that now sit in a confusing place.
Apply the order. Reorder the playlist by hand, or use a tool that does it for you.
Start from the top. Begin with the first lesson and move down the list.
Keep short notes as you go. Short lessons pass quickly, so a line or two per lesson helps the ideas stick.
Review after the first few sessions. If the order is not working for your learners, change it.

Tools that can do it

You do not need software for this. Here are options to consider, and the table above shows how each one orders the lessons.

Paper list or sticky note. You write each title and length and rank them by hand. This needs nothing to install and works away from a screen.

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 each app's 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]

YTSort shows the before and after order so you can check it before applying. ^[1] It sorts the full playlist, not just the lessons loaded on screen. ^[1] It can sort only lessons within a length range and move the rest to the end. ^[1] It shows total, average, shortest and longest lesson length for the playlist. ^[1]

YTSort is free. ^[1] You can get it through a bookmark, a browser script, or a Chrome Web Store extension. ^[1] The extension needs Chrome or Edge. ^[1]

Common mistakes to avoid

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

Trusting the order without a look. Read the new order once before you share it with learners. A quick check catches lessons that ended up in an odd spot.

Forgetting the longest lessons. Moving them to the end is fine, but give them a set time or they may never be watched.

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

Changing the order of a live course without telling learners. A new order changes what learners see first. Tell them where to start after you make the change.

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

Frequently asked questions

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

List each lesson with its length, then rank them from shortest to longest. Apply that order to the playlist by hand, or use a tool that sorts for you. YTSort is one such tool, and it reorders a YouTube playlist you own by lesson length, shortest or longest first. ^[1] Check the result before your learners see it.

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 from top to bottom before you publish. Look for lessons that now sit in a confusing spot, especially ones that build on earlier lessons.

Which browsers work with YTSort?

The extension needs Chrome or Edge. ^[1] You can also run YTSort from a bookmark. ^[1]

Should course builders always put the shortest lessons first?

Not always. If a course builds lesson by lesson, keep dependent lessons in their original order. Shortest first can suit a free half hour or a quick start. For longer courses, review the order after a few sessions and change it if your learners need something different.

Is YTSort free to use?
