A YouTube intro should be 5 to 15 seconds long: enough to confirm the title's promise and say what the viewer will get, then start. If you use a branded intro (a logo animation or theme), keep it to 2 to 5 seconds and put it after the hook, not before. YouTube Studio's Intro metric reports how many viewers are still watching at 30 seconds, so everything before the main content should fit well inside that window.

Below: lengths in seconds and words, what the Intro metric means, examples of intros by video type, and how to fix one that loses people.
The short answer
Aim for a 5-15 second spoken hook (about 12-38 words at 150 words per minute), then start the content. A branded bumper, if you use one, should be 2-5 seconds and come after the hook. For Shorts, there's no intro: the first second is the hook. Judge it with YouTube Studio's Intro metric, the share of viewers still watching after 30 seconds.
Key takeaways
- Hook: 5-15 seconds, which is about 12-38 words at an average 150 wpm.
- Branded intro or logo sting: 2-5 seconds, after the hook, or none at all.
- YouTube's Intro metric = viewers still watching at 30 seconds; a flat line early is the goal.
- Repeat the title's promise in the first sentence; viewers leave when the opening doesn't match the click.
- Shorts and clips need no intro; start on the most interesting frame.
How long should a YouTube intro be?
A YouTube intro should be 5 to 15 seconds of spoken hook, plus at most 2 to 5 seconds of branding. The exact length depends on how much the viewer needs to hear before they trust the video will deliver:
| Video type | Hook length | Branded intro |
|---|---|---|
| Shorts and clips | 0-2 seconds (first line is the hook) | None |
| Tutorials and how-tos | 5-10 seconds | 0-3 seconds |
| Reviews and comparisons | 10-15 seconds | 0-3 seconds |
| Podcasts and interviews (video) | 15-30 seconds of best moment, then intro | 3-5 seconds |
| Long-form story or documentary | 15-30 seconds cold open | 3-5 seconds |
These are working ranges, not YouTube rules. YouTube doesn't set an intro length; it measures what viewers do, and the measure to watch is in the next section.
What does YouTube's Intro metric measure?
YouTube's Intro metric measures the percentage of viewers still watching after the first 30 seconds. It sits in YouTube Studio's key moments for audience retention report, alongside the retention chart. YouTube's help page explains that a flat line means viewers are watching that part from start to finish, and dips mean they're abandoning or skipping at that point; if your best moments come late, it suggests introducing them earlier.
| What you see in the first 30 seconds | What it usually means | What to change |
|---|---|---|
| Steep drop in the first 5 seconds | Opening doesn't match the title or thumbnail | Open with the promise, in the title's words |
| Steady slide through 10-30 seconds | Intro is too long or too slow | Cut greetings, channel plugs and recaps |
| Spike or skip at a fixed second | Viewers skip your branded intro | Shorten it to 2-3 seconds or remove it |
| Flat line after 15 seconds | The hook worked | Keep the format |
Compare your Intro percentage with your own other videos rather than a universal benchmark: it varies by niche, length and how viewers found the video.
How many words should a YouTube intro be?
A YouTube intro should be about 12 to 38 words for a 5-to-15-second hook. Most people speak around 150 words per minute on camera, or 2.5 words a second:
| Hook length | Words at 130 wpm (slow) | Words at 150 wpm (average) | Words at 170 wpm (fast) |
|---|---|---|---|
| 5 seconds | 11 | 13 | 14 |
| 10 seconds | 22 | 25 | 28 |
| 15 seconds | 33 | 38 | 43 |
| 30 seconds | 65 | 75 | 85 |
Write the hook, read it aloud and time it, or paste it into the free words to minutes calculator at your speaking rate. Average speaking rate has rates for different kinds of speech, and how many words per minute for a video script covers whole scripts.
What should a YouTube intro say?
A YouTube intro should say what the viewer gets, why it's worth watching to the end, and then get out of the way. A simple structure that fits 10 to 15 seconds:
- Confirm the click (1 sentence). Repeat the title's promise: "Here's how to remove background noise from a video in under a minute."
- Show proof (1 sentence or a 2-second shot). The before-and-after, the finished result, the number.
- Set up what's next (1 sentence). "Three methods, free first." Then start method one.
Leave out "Hey guys, welcome back", requests to subscribe, sponsor reads and recaps of last week's video in the first 30 seconds. Put them after the first payoff, or at the end. For more hook formulas, see how to write a hook for short videos; most of them work for long videos too.
What do good YouTube intros look like?
Good YouTube intros state the payoff in the first sentence and start the content by the 15-second mark. Three examples, each about 10 to 12 seconds read aloud:
| Video | Intro (spoken) | Words |
|---|---|---|
| Tutorial: "How to add subtitles to an MP4" | "Here's how to put subtitles into an MP4 so they show on every player. Two ways: a free app, and one command if you're comfortable with FFmpeg. Free way first." | 30 |
| Review: "Budget mic vs USB mic" | "I recorded the same sentence on a $25 mic and a $120 USB mic. You'll hear both in ten seconds, then where the extra money actually goes." | 27 |
| Podcast episode | A 15-second highlight from later in the episode, then: "That's from my talk with a bakery owner on pricing. Here's the full conversation." | 18 + clip |
Notice what's missing: no greeting, no channel name, no request to subscribe. They come later, once the viewer has a reason to care.
Should you have a branded intro on YouTube?
Only if it's short. A 2-to-5-second logo sting or theme can make a series recognisable, but viewers who already clicked don't need it, and a long animated intro is where many of them skip or leave. Put it after the hook so the first thing people see is the content they clicked for. If your Intro metric shows a dip right where the bumper plays, cut it to 2 seconds or drop it.
| Branded intro | Verdict |
|---|---|
| None | Fine for most channels |
| 2-3 second logo sting after the hook | Good for series and brands |
| 5 seconds with theme music | Acceptable for podcasts and shows with returning viewers |
| 10+ seconds of animation before any content | Avoid |
How do you fix an intro that loses viewers?
You fix an intro that loses viewers by cutting until the first useful thing happens within a few seconds:
- Open the video's retention chart and find where the first big drop ends.
- Trim everything before the first useful line with the free video trimmer (or in your editor) and re-upload future videos with the tighter opening. For a published video, YouTube Studio's editor can trim it without a new upload.
- Rewrite the first sentence to match the title word for word; check the title itself with the free YouTube title length checker so it isn't cut off.
- Add chapters so viewers who want a specific part can jump to it instead of leaving. The first chapter must start at 0:00; the free YouTube chapter timestamp generator formats the list for you.
Captions also help people stay through a slow first few seconds, especially on mobile with sound off. QuickVeed's auto subtitles transcribe a video and export SRT for YouTube. For the full picture on video length, see YouTube's video length limit.
For longer scripts, the words to minutes conversion chart turns any word count into speaking time.
Frequently asked questions
How long should a YouTube intro be in seconds?
A 5 to 15 second hook, plus no more than 2 to 5 seconds of branding.
Is a 30-second YouTube intro too long?
Usually, yes. YouTube's Intro metric measures how many viewers remain at 30 seconds, so the hook should be over well before that.
How many words is a 10-second intro?
About 25 words at an average 150 words per minute.
Do YouTube Shorts need an intro?
No. Start with the most interesting frame or line; the first second is the hook.
Where do I find the Intro metric?
In YouTube Studio, open a video's analytics and look at the key moments for audience retention report.
Should the intro come before or after the hook?
After. Show or say the payoff first, then play any branded intro.
