Basics
How long should an explainer video be? The right length for every use
The right explainer video length depends on where it plays and how much your viewers already know. Benchmarks for your website, ads, sales and training, plus word counts for your script.

Key takeaways
- For most explainer videos on a homepage or product page, 60 to 90 seconds is the right length.
- Ads and social clips work best at 6 to 30 seconds; training and onboarding videos can run several minutes.
- Spoken English runs at roughly 130 to 150 words per minute: 60 seconds holds about 130 to 150 words, 90 seconds about 200 to 220.
- The number of seconds matters less than whether every scene moves the story forward. A clear longer film beats a crammed short one.
"Keep it as short as possible" is the most common advice on explainer video length. It isn't wrong, but it doesn't help much. A 30-second film that only teases your offer loses prospects just as surely as a five-minute film that walks through every feature.
The right length comes from three questions: Where will the video play, how much do viewers already know, and how much do they need to understand afterward? This guide gives you benchmarks for the most common uses, converts length into script word counts, and shows how to tell when your film is too long.

The short answer: 60 to 90 seconds
For the classic explainer on your homepage or product page, 60 to 90 seconds is almost always right. That's enough for a complete little story: a situation your viewers recognize, your offer as the answer, two or three concrete examples of how it helps, and one clear next step.
Go shorter and things get tight once your offer needs any explaining. Go longer when viewers have already chosen to learn something, for example in training or after a sales call.

| Use | Recommended length | Why |
|---|---|---|
| Homepage, product page | 60–90 seconds | First contact: enough for problem, solution and an example |
| Campaign landing page | 45–75 seconds | One offer, one promise, one action |
| Paid ads (social, YouTube) | 6–30 seconds | Attention has to happen in seconds |
| Social post, story | 15–45 seconds | Vertical, often muted, quick impact |
| Sales follow-up | 1.5–3 minutes | Prospects want details and decision arguments |
| Product tour, software demo | 1–3 minutes | One complete workflow instead of every feature |
| Training, onboarding | 2–5 minutes per lesson | Viewers want to learn and apply something |
| Trade show, waiting-room screen | 30–90 seconds on a loop | Passers-by join at any moment |
| YouTube video, in-depth explainer | 7–20 minutes | Intentional search, chapters, depth over speed |
Treat these as starting points, not rules. A film can run longer if every scene is needed. It has to get shorter if scenes only repeat each other.
From seconds to words: how much script fits
The voice almost always sets the length of an explainer. Animation, music and pauses follow it. So planning the length really means planning the word count of your script.
Spoken English in explainer videos runs at roughly 130 to 150 words per minute, including short pauses between ideas. That gives you:

| Video length | Words of narration (English) |
|---|---|
| 30 seconds | about 65–75 |
| 60 seconds | about 130–150 |
| 90 seconds | about 200–220 |
| 2 minutes | about 260–300 |
| 5 minutes | about 650–750 |
Read your script out loud with a stopwatch. If you have to rush, cut sentences, not pauses. Our guide to writing an explainer video script shows how to write to exactly this length.
30, 60 or 90 seconds: short explainer videos compared
Most briefs land on one of three short lengths. Each one can carry a different amount of story, and knowing the difference saves you from writing a 90-second script for a 30-second slot.

| Length | Narration | Carries | Fits best |
|---|---|---|---|
| 30 seconds | about 65–75 words | One message and one next step | Ads, social feeds, teasers |
| 60 seconds | about 130–150 words | Situation, offer, one example, next step | Landing pages, simple offers, social |
| 90 seconds | about 200–220 words | The full arc including how-it-works and proof | Homepage, product page, sales |
30-second explainer videos
Thirty seconds holds one idea: a single benefit, a single moment, a single promise, then the next step. That's exactly right for paid ads and social feeds, where the clip has to work mid-scroll and often without sound, and for a teaser cut from a longer film. It's too short to explain how anything works. If your offer needs even two steps of explanation, a 30-second film will only tease it, and viewers who click through still arrive uninformed. Write it as its own piece, not as a compressed version of the long script: one scene, one line of large text, one action.
60-second explainer videos
A minute is the smallest complete explainer: the viewer's situation, your offer as the answer, one or two concrete examples of how it helps, and the next step. It suits campaign landing pages, offers that are simple once stated, and anywhere viewers decided to press play but won't forgive padding. The discipline is in what you leave out: at 130 to 150 words there is no room for a feature list and the how-it-works, so pick the one that moves your viewer. A 1-minute explainer video is also the most common ask in briefs, often simply because it sounds tidy; check against your script's word count before you commit to it.
90-second explainer videos
Ninety seconds is the homepage default for a reason: it's the shortest length that fits the whole story. You get the situation, the offer, two or three real steps of how it works, a piece of proof and the call to action, without the voice racing. Most of the films in our style gallery for real businesses run about this length. It's the right choice when your offer genuinely needs explaining, and the wrong one when a script that belongs at 60 seconds gets inflated to fill it. Past 90 seconds, be honest about which film you're making: either cut back, or commit to a longer format for viewers who have already chosen to learn more.
What determines the right length
How much your viewers already know
Someone seeing your offer for the first time needs a reason to keep listening before anything else. Someone who's already talked to your team wants details. A film for first-time visitors is shorter and focused on the problem. A film for prospects close to a decision can run longer and answer objections.
How complex your offer is
An office breakfast delivery service can be explained in 45 seconds. Software that connects workflows across three departments needs closer to 90 seconds or more. Rule of thumb: keep going until an outsider can say in one sentence what your offer does for them.
Where the video plays
On your website, visitors actively choose to hit play. In a social feed, you have to catch them mid-scroll. At a trade show, people walk in halfway through and leave again. Each place calls for a different length and structure.
What viewers should do next
If you want someone to book a demo, a short film that sparks curiosity is often enough. If someone has to complete a task themselves, like setting up software, the film needs to show every step and can be longer.
Signs your video is too long
- The opening takes more than ten seconds before it's clear what this is about.
- Two scenes say the same thing with different visuals.
- The film lists features instead of showing a workflow.
- The call to action comes after a long recap that adds nothing new.
- Test viewers can't say in one sentence what your offer does.
And the sign it's too short: test viewers get the slogan, but not how it works or what it means for them.
One video or several?
If your script grows past two minutes even though every scene matters, you probably have two films. A short one for the homepage sparks interest; a longer one for the product page or sales conversations delivers detail. With a shared style and the same characters, both versions come together cleanly. Length is also a cost lever, because most providers price per finished minute.
With Capri Video, an explainer runs up to two minutes and uses 2 credits; a short video uses 1. For several videos a month there's the Growth plan; longer lengths or language versions are a custom package.
FAQ
Is a shorter explainer video always better?
No. Shorter is only better if everything important stays clear. A 40-second film that leaves viewers unsure what you offer is wasted. Brevity comes from cutting what's secondary, not from talking faster.
How long should an explainer video for social media be?
For ads and feeds, 6 to 30 seconds works best. The first two seconds must make sense without sound, so captions and a strong first frame help.
How long should a training video be?
Two to five minutes per lesson. Split longer topics into several short videos that each cover one learning goal.
Is a 2-minute explainer video too long?
It depends on who is watching. For a first contact on a homepage, two minutes is usually more than the offer needs, and 60 to 90 seconds holds attention more reliably. For viewers who have already chosen to learn more, in a sales follow-up, a product tour or training, two minutes is a normal length. The real test is whether every scene still moves the story forward.
Does a longer explainer video cost more?
Usually, yes. Most freelancers and studios price per finished minute, because every extra second has to be written, designed, animated and narrated. Some lower the per-minute rate for longer films, since the concept and style are developed only once. Credit-based subscriptions work differently: at Capri Video, an explainer up to two minutes always uses 2 credits.
How long can an explainer video be on YouTube?
People searching for an explanation will stay for 7 to 20 minutes if the film is well structured: a strong opening, clear chapters and real depth instead of repetition.
How many words do I need for a 90-second video?
In English, about 200 to 220 words. Aim for the lower end so the voice and visuals have room to breathe.
Is a 30-second explainer video enough?
For one message, yes: an ad, a teaser, a single benefit worth remembering. For an offer that needs any explaining, 30 seconds forces you to skip the how-it-works, and 60 to 90 seconds serves you better.
What is the difference between a 60-second and a 90-second explainer video?
About 70 words of narration. A 60-second film covers the situation, your offer, one example and the next step. A 90-second film adds what most offers are missing at 60: the how-it-works in real steps and a piece of proof.
