How to Add Chapters to a YouTube Video (Step-by-Step)

Chapters break a long video into labeled sections viewers can jump to. They take two minutes to add, they are free, and they make your video feel more professional instantly. Here is exactly how to add them and the rules that trip most people up.

The fastest way: timestamps in the description

YouTube generates chapters automatically from a list of timestamps in your video description. You do not need any special tool — just the right format:

1. Open YouTube Studio, pick your video, and go to Details.
2. In the Description box, add a list of timestamps, one per line.
3. Make the first timestamp 00:00 with a label like 'Intro'.
4. Add a short title after each timestamp, for example '02:15 The main mistake'.
5. Save. Chapters appear on the progress bar within a minute or two.

A correct chapter list looks like this:

• 00:00 Intro
• 01:10 Why this matters
• 04:30 Step-by-step walkthrough
• 09:45 Common mistakes
• 12:20 Recap

The rules YouTube requires

Chapters silently fail if you break any of these, so check them first when yours do not show up:

• The first timestamp must be 00:00.
• You need at least three timestamps in ascending order.
• Each chapter must be at least 10 seconds long.
• Use the format mm:ss (or hh:mm:ss for videos over an hour).

If a chapter is too short or the order is off, YouTube ignores the whole list rather than showing partial chapters.

Skip the manual typing

Counting timestamps by hand is tedious, especially on longer videos. Our free YouTube chapters generator formats a clean, valid chapter list you can paste straight into the description, and the YouTube description generator builds the rest of the description around it.

Why chapters are worth the two minutes

Chapters raise the odds a viewer finds the exact part they came for, which protects watch time — the metric YouTube cares about most. See watch time vs views for why that matters, and pair chapters with a strong description using our description SEO guide.
