How to Add Chapters to YouTube Videos (and Why They Don't Show Up)

Chapters split a video into labelled sections on the progress bar, so viewers can jump straight to the part they came for. They make longer videos far easier to navigate, and they give viewers a quick outline of what a video covers before they commit to watching.

Adding them takes a few minutes, but the rules are strict: one small formatting slip and the chapters simply don't appear. This blog covers the exact rules, a step-by-step walkthrough, automatic chapters, and a checklist for fixing chapters that won't show.

The rules chapters must follow

According to YouTube's Help Center, manual chapters only appear when the timestamps in your description meet all of these:

1. The first timestamp starts at 00:00.
2. There are at least three timestamps, listed in ascending order.
3. Every chapter is at least 10 seconds long.

All three have to be true at once. A list that's perfect except for starting at 00:05 won't produce chapters.

How to add chapters, step by step

1. Open YouTube Studio and select Content in the left-hand menu.
2. Click the video you want to edit to open its Details page.
3. In the Description box, add your list of timestamps, one per line, each followed by a chapter title.
4. Click Save.

A description with chapters looks like this:

In this video I test the new camera for a full week of everyday shooting.

00:00 Introduction
00:42 What's in the box
02:15 First impressions
05:30 Battery life test
08:04 Low-light footage
11:20 Final verdict

You can place the list anywhere in the description, and the rest of your description stays exactly as it is.

Formatting that works

• Use minutes and seconds like 05:30 for most videos, or hours, minutes and seconds like 1:02:10 for videos over an hour.
• Put one timestamp per line, at the start of the line, followed by the chapter title.
• Keep the list in order. Each timestamp has to be later than the one before it.
• Leave at least 10 seconds between timestamps. A chapter that starts at 02:15 means the next one can't start before 02:25.

Automatic chapters

YouTube can also create chapters for you. When Allow automatic chapters is turned on, YouTube may generate chapters for a video that doesn't have its own. The setting is on by default for new uploads.

If you add your own timestamps to the description, those take priority. Automatic chapters are a helpful fallback, but manual chapters give you control over where each section starts and what it's called.

To turn automatic chapters off:

• For one video: open the video in YouTube Studio, go to the advanced settings on its Details page, and untick Allow automatic chapters.
• For all future uploads: go to Settings → Upload defaults → Advanced settings and change the option there.

The Help Center also notes that not every video is eligible for automatic chapters, and that the chapters feature isn't available when a channel has active strikes or when content may be inappropriate for some viewers.

Why your chapters aren't showing

If you've added timestamps and nothing appears on the progress bar, work through this table. It's almost always one of these.

Remember that all the rules apply together. Fixing one problem won't help if a second one is still there, so check the whole list rather than stopping at the first issue you find.

Writing chapter titles viewers actually use

Chapters only help if the titles tell people where to go. A few habits make a big difference:

• Describe what happens in the section, like "Battery life test", rather than "Part 3".
• Keep titles short so they fit on the progress bar, especially on mobile.
• Use the words viewers would search for. If people want the "low-light footage" section, call it that.
• Don't over-split. A chapter every 20 seconds makes the bar harder to use, not easier. Aim for the natural sections of the video.

Adding chapters to older videos

You don't need to limit chapters to new uploads. Older videos that still get steady views are often the best place to start, because the benefit reaches viewers straight away.

Pick your most-watched long videos, add a chapter list to each description, and save. It's one of the quickest improvements you can make to a back catalogue, and it doesn't require re-uploading anything.
