Short answer: As short as possible while still telling viewers they are in the right place. YouTube does not publish an ideal intro length, but its creator guidance has long said the first few seconds are critical and that your content, not a flashy intro, should come first. A practical rule is to confirm the title's promise within the first few seconds and keep any branded sequence brief, or put it after the hook.
Does YouTube recommend a specific intro length?
No. We could not find any official YouTube page that gives an ideal intro length in seconds. What YouTube has published is guidance about the opening:
- A 2011 YouTube Creator Playbook post on "the first 15 seconds" advised starting with "something that will immediately grab attention" and warned that "a flashy intro may look cool, but it's not the star of the video."
- A 2014 YouTube post on hooking viewers said "the first few seconds of any video are critical," and gave the example of a creator making clear within five seconds what the video was about.
- YouTube Studio's retention report includes an "intro" figure: the percentage of viewers still watching after the first 30 seconds.
None of these is a rule about intro length. They all point the same way, though: get to the point fast. Be wary of articles that quote an exact "ideal" intro length without a source.
What is the difference between a hook and an intro?
People use the words differently, so it helps to separate them:
- The hook is the opening lines or shots that confirm what the video is about and give a reason to keep watching.
- The intro is everything before the main content: the hook, plus any greeting, logo animation, channel plug or sponsor read.
The hook earns its time. The rest of the intro often does not, at least for new viewers who do not know you yet. So the better question is not "how long should my intro be?" but "how much of my intro is not the hook?" Our guide to hooks for the first 30 seconds covers how to write one.
Should you use a branded intro animation?
Only if it is short and does not delay the content. The 2011 YouTube post suggested letting viewers "see you, or your great content, first," and making branding entertaining or unique to each video. The 2014 post praised a channel whose intro "feels integrated into the content itself."
A practical approach is to place a brief logo sting after the hook, once viewers know the video is worth watching, rather than before it. If your retention graph shows a drop during the animation, cut it.
How long should the intro be for different kinds of video?
There is no fixed number, but the right amount depends on what the viewer came for:
- Tutorials and how-to videos: Viewers want the answer. Say what they will be able to do, then start.
- Stories and documentaries: A cold open that drops viewers into a key moment can work before any setup.
- Podcasts and interviews: A short clip of the best moment as a cold open, then straight into the conversation. See retention editing for podcasts.
- Shorts: No intro. The first frame is the hook. See short-form retention editing.
What should you cut from your intro?
- Greetings before the hook ("hey guys, welcome back").
- Explaining what you are about to explain.
- Subscribe or like requests before you have delivered anything.
- Channel news unrelated to the video.
- Long logo animations.
- Recaps of earlier videos that new viewers have not seen.
If a sponsor read has to go near the start, try placing it after the hook, so viewers already know why they are staying.
How do you test whether your intro is too long?
- Open the audience retention report for a recent video and check the intro figure: the share of viewers still watching after 30 seconds.
- Look at the shape of the graph in those first 30 seconds. A steep drop during a greeting or animation is a sign to cut it.
- Compare the video with typical retention for your 10 latest videos of similar length.
- Change one thing in the next video, such as cutting the logo or moving the hook earlier, and compare again.
Length is not the only thing to check. YouTube says a strong intro can mean the first 30 seconds matched what viewers expected from the title and thumbnail, and suggests changing the title and thumbnail to better reflect the video. Our guide to matching your hook to your title and thumbnail explains how.

Frequently asked questions
Is a 10-second intro too long?
It depends on what happens in those 10 seconds. Ten seconds of hook that confirms the video's promise is fine. Ten seconds of logo animation or greeting before anything useful is likely to cost you viewers, so check your retention graph.
Should I say hello at the start of my videos?
A quick greeting is fine if it comes with or after the hook. A long welcome before viewers know what they will get delays the reason they clicked.
Where should I put a sponsor read?
If you can, place it after the hook, once viewers know why they are staying. Putting it before any content asks new viewers to wait before they have been given a reason to.
Do branded intros help channel recognition?
They can, especially when they are short and part of the content. YouTube's own tips praised an intro that feels integrated into the content itself. A long, identical intro on every video mainly delays the content.
What does the intro figure in YouTube Studio mean?
It is the percentage of viewers still watching after the first 30 seconds of your video. YouTube says a strong figure can mean the opening matched what viewers expected from the title and thumbnail.
