How to Add YouTube Chapters With Timestamps Easily

9 min read

Last updated November 12, 2026

YouTube chapters split a video into named parts on the progress bar. You add them by typing timestamps in the video description, starting with 0 seconds.

YouTube then turns that list into clickable sections. Viewers can jump straight to the part they need, and your video becomes easier to search.

This guide shows the exact rules and the steps on desktop and phone. It also covers the small mistakes that hide chapters.

Key Takeaways

Chapters come from timestamps you type in the description.
The first timestamp must start at zero.
You need at least three chapters, listed from first to last.
Each chapter must last at least 10 seconds.
Your own chapters replace the automatic ones.

What YouTube Chapters Are and Why They Help

A chapter is a labeled slice of your video. Each slice shows as a small gap on the red progress bar.

When a viewer hovers over the bar or drags it on a phone, the chapter name appears. That preview tells them what comes next.

Chapters help in three simple ways.

Viewers stay longer. People who can skip to the part they want are less likely to leave.
Your video is easier to scan. A list of topics in the description works like a table of contents.
Search can show key moments. Clear chapter names give search engines more context about each part.

Chapters matter most on longer videos. Tutorials, reviews, podcasts and lessons gain the most because viewers often look for one answer.

A one-minute clip rarely needs them. In fact, very short videos cannot meet the 10-second rule for three parts in a useful way.

The Four Rules YouTube Checks

YouTube lists its chapter rules on the official Video Chapters help page. Your timestamps must pass every one of them.

Rule	What it means for you
Start at zero	The first line must use the very first second of the video
At least three	You need a minimum of three timestamps
In order	Times must go from the start of the video to the end
10 seconds or longer	No chapter can be shorter than 10 seconds

If even one rule fails, YouTube ignores the whole list. The timestamps stay clickable in the description, but the progress bar shows no sections.

10 secondsThe shortest length YouTube allows for any single chapter, per the official YouTube chapters rules.

Write each timestamp at the start of its own line. Put the chapter name right after it, with a space between them.

How to Add Chapters Step by Step

You can add chapters before you publish or long after. The steps are almost the same on a computer and a phone.

On a computer

Sign in to YouTube Studio and open Content from the left menu.
Click the video you want to edit.
Find the description box on the Details page.
Type your timestamps, each on a new line with a chapter name.
Click Save in the top corner.
Open the video and drag the progress bar to check the sections.

On a phone

Open the YouTube Studio app and tap Content.
Tap the video, then tap the pencil icon to edit.
Tap the description and add your timestamp lines.
Tap Save and give YouTube a few minutes to update.

Here is a simple example you can copy and change. Each line starts with the time and ends with a short name.

0:00 Intro
0:42 What you need
2:15 Step one, set up
5:30 Step two, test it
8:05 Common mistakes
10:20 Final tips

Quick tip. Watch your final edit with a notepad open. Write down the time each new topic starts, then round to the nearest second.

Videos longer than one hour need hours in the first number. Write them the same way, with the hour before the minutes.

How to Name Each Chapter

Good chapter names are short, clear and specific. Two to six words is a good target for most videos.

Think about what a viewer would type into search. A name like “Cleaning the filter” beats “Part three” every time.

Names that work

Say the topic, not the order, such as “Best budget pick”.
Use words your viewers already use.
Keep each name different from the others.
Match the name to what actually happens on screen.

Names to avoid

Vague labels like “More stuff” or “Next”.
Long sentences that get cut off on phones.
Keyword lists that repeat the same phrase.
Teasers that promise something the part never shows.

That last point matters for more than style. The YouTube spam policy bans misleading titles, thumbnails and descriptions that do not deliver.

Your chapter list sits inside the description, so it follows the same rules. Honest names build trust and keep viewers watching.

Automatic Chapters and When to Turn Them Off

YouTube can also create chapters for you. New uploads usually have the setting “Allow automatic chapters” switched on by default.

Automatic chapters save time, but they guess. The names may be too general, and the breaks may land in odd places.

Your own timestamps always win. According to the YouTube help page, manual chapters override automatic ones as soon as you save them.

To switch the feature off for one video, open it in Studio and click Show more. Then untick “Allow automatic chapters” and save.

You can also change the default for future uploads. Go to Settings, then Upload defaults, then Advanced settings.

Good to know. Not every video qualifies for automatic chapters. Channels with active strikes and some sensitive videos do not get them.

Why Your Chapters Do Not Show

Most chapter problems come from one small mistake. Work through this list before you assume something is broken.

Problem	Likely cause	Fix
No sections at all	First time is not zero	Start the list at the very first second
Only some times are links	A chapter is under 10 seconds	Merge it with the next part
List ignored	Fewer than three timestamps	Add at least one more chapter
Wrong order	A later time sits above an earlier one	Sort the lines from start to end
Old chapters remain	Change not saved yet	Save, then refresh the watch page

Formatting can trip you up too. Keep each timestamp at the start of a line, and avoid extra symbols in front of it.

If the list is right, give it a little time. Changes can take a few minutes to appear on the watch page and in the app.

Make Chapters From Your Script in Seconds

Working out times by hand gets slow on long videos. A script gives you a faster shortcut.

Most people speak at roughly 150 words per minute. So the number of words in each part of a script hints at how long that part runs.

The free Postlume YouTube chapters generator uses that idea. Paste your script or outline, add the video length, and it spreads the times for you.

It also follows the rules above. The list always starts at zero, keeps at least three parts and drops any part under 10 seconds.

Need the script first? The Postlume script generator plans each part with timing. Then the description generator writes the text around your chapters.

Check before you publish. Times from any tool are estimates. Always compare them with your final edit and adjust a few seconds where needed.

Where Chapters Fit in Your Description

YouTube shows only the first lines of a description before viewers tap “more”. The official tips for video descriptions suggest using those lines to describe the video.

So place your chapter list after a short summary. That way the opening still explains the video, and chapters sit one tap away.

A simple order works well for most creators.
