What are YouTube chapters?
Chapters split your video's progress bar into named, clickable segments built from a simple list of times and titles in your description. They turn one long upload into a navigable outline: exactly what people expect from tutorials, reviews, interviews and recorded talks. The catch is that YouTube only shows them when your list passes a few strict rules, which is where most creators get stuck.
YouTube chapter requirements (the 3 rules)
For chapters to appear, your list must satisfy three conditions at the same
time: the first chapter has to begin at 00:00, you need at least
three chapters, and every chapter must run for ten seconds or more. Times must
also be in order from earliest to latest. Break any one of these and YouTube
silently disables the whole feature: no error, just no chapters. This maker
checks all three as you type and shows a red flag the moment a rule is broken.
Why your YouTube chapters aren't showing
If you pasted a list and no markers appeared, it is almost always one of these:
- A broken rule: the first line isn't 00:00, you have fewer than three chapters, or one is under ten seconds long.
- A formatting slip: a symbol or word before the time (
• 04:20,Step 1 04:20), a space inside the time (0: 12), brackets, or a period instead of a colon. - A link between chapters: a clickable URL sitting between two timestamps can disable the list.
- Processing time: new chapters can take up to 72 hours to show on the progress bar, so a valid list may simply need time.
- Channel restrictions: an active Copyright or Community Guidelines strike disables advanced features, including chapters.
Note the myth: there is no subscriber minimum, and even a channel with zero subscribers gets chapters when the formatting is correct.
Chapter rules and what breaks them
| Requirement | Rule | If you break it |
|---|---|---|
| First chapter | Must start at exactly 00:00 | No chapters appear at all |
| Number of chapters | At least three | The feature stays off |
| Chapter length | Each ten seconds or longer | Chapters are disabled |
| Order | Times ascending, earliest first | The list is ignored |
| Line format | Time first, no brackets or links | YouTube can't parse the line |
How to add chapters to a video
Build your list above until the errors panel is empty, then copy the YouTube description output and open your video in YouTube Studio. Paste the list anywhere in the description box, keeping each chapter on its own line, and save. Markers usually appear within a few minutes, but allow up to 72 hours before assuming something is wrong. Need to build the list first, or want it in Markdown, CSV or JSON too? Use the YouTube Timestamp Generator to format your times, then bring the list back here to validate the chapter rules.

Frequently asked questions
What are the rules for YouTube chapters?
Three rules must all be met: the first chapter must start at 00:00, there must be at least three chapters in total, and every chapter must last 10 seconds or more. If any rule is broken, YouTube quietly ignores the chapters. This maker flags each issue as you type.
Why are my chapters not showing up on my video?
Usually one of a few things: a first chapter that isn't 00:00, fewer than three chapters, a chapter under 10 seconds, or a formatting slip such as a symbol or word before the time. A clickable link sitting between chapters can also disable them. Clear the warnings panel here before you paste the list.
How long do chapters take to appear after I add them?
Often a minute or two, but YouTube says it can take up to 72 hours for newly added chapters to process and show on the progress bar. If the format is valid and the warnings panel is clear, give it some time before assuming it's broken.
Do I need a minimum number of subscribers for chapters?
No. There is no subscriber requirement for manual chapters: a channel with zero subscribers can use them, as long as the formatting is correct and the channel has no active strikes disabling advanced features.
How many chapters should a video have?
The minimum is three; there is no practical maximum. Match the count to your content: a short tutorial might have four or five clear sections, while a long stream could have a dozen. Favour meaningful sections over splitting hairs.
Do chapters work on YouTube Shorts?
No. Chapters are a feature of regular long-form videos shown on the progress bar. Shorts use a different vertical player without a chapter bar, so adding times to a Short's description will not create clickable sections.
Are YouTube chapters good for SEO?
They help indirectly. Clear chapter titles describe your content to both viewers and YouTube, can surface as key moments in Google search results, and tend to improve watch time because people find what they want. Write descriptive titles using the words your audience would search for.
