List every video in the playlist with its length, rank them from shortest to longest to fit your study windows, and apply that order to the playlist. You can do it by hand on paper or in a spreadsheet.

What you need before you start

Planning study playlists by video 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 videos into your own first or work from a written list.
The length of each video. YouTube shows it on each thumbnail. You need it to plan which videos fit which study block.
A study schedule with time blocks. Certification candidates often have uneven free time between work and exam dates. Know how long each block is, because it decides which videos go where.
A reason for planning by length. It might be to fit a 20-minute commute or to save the longest lectures for weekend sessions. Know which, because it decides what you do with the long videos.
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 watching 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 plan. Make sure you can access the playlist before choosing a way to order videos by length.
List every video with its length. Write the title and the time shown on the thumbnail. Do not sort yet.
Mark videos that must stay in order. Some certification courses build on earlier lessons. If module two needs module one, keep those two together.
Group videos by study window. Put short videos into weekday slots and long videos into weekend or evening slots where you have more time.
Rank the rest from shortest to longest. Put the shortest at the top of each group.
Decide what happens to the very long videos. 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 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.
Study from the top. Start with the first video for that block and move down the list.
Keep notes as you go. Short videos pass quickly, so a line or two per video helps the ideas stick for exam day.
Review after the first few sessions. If the order is not helping you prepare, 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 study 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 Chrome or Edge add-on needs those browsers, and the script version works in any browser, including Firefox, with Tampermonkey, Violentmonkey or Greasemonkey installed. ^[1]

YTSort sorts the full playlist, not just the videos loaded on screen. ^[1] It can also sort only videos within a length range and move the rest to the end, which helps if you want to study short clips on a weekday and long lectures on a weekend. ^[1] It shows total, average, shortest and longest video duration for the playlist, so you can see how the playlist breaks down across your study blocks. ^[1] It exports position, title, duration and URL of every video to a CSV file, which you can open in a spreadsheet to plan around your schedule. ^[1]

Common mistakes to avoid

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

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

Forgetting the long videos. 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 videos into your own playlist or keep a written list.

Studying without notes. Short videos go by fast, so notes can help you keep track of what you covered for exam review.

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

Frequently asked questions

How to plan a YouTube study playlist by video length for certification prep?

List each video with its length, group them by study window, rank from shortest to longest within each group, then apply that order to the playlist by hand or with a tool. Check each tool's current details before choosing how to sort your playlist.

How to sort a YouTube playlist from shortest to longest for exam study?

List each video with its length, rank them from shortest to longest, then apply that order by hand in the playlist. If your course builds module by module, keep dependent lessons in order rather than sorting every video purely by length.

Can YTSort show the new playlist order 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 studying.

Which browsers work with YTSort?

The Chrome or Edge add-on needs those browsers. The script version 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]

Should certification candidates always study the shortest videos first?

Not always. If a course builds module by module, keep dependent lessons in order. Shortest first can suit a short weekday study block. For long certification courses, review the order after a few sessions and change it if it is not helping you prepare.

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