How Long Should an Explainer Video Be? The Perfect Length for More Views, Engagement & Conversions
The ideal explainer video length is usually 60–90 seconds. That is long enough to explain a problem, introduce a solution, communicate the key benefits, and deliver a clear call to action without asking viewers for more attention than necessary.
But there is no magic number.
A great explainer video is not successful because it is exactly 60 seconds long. It is successful because it delivers the right message in the right amount of time.
And that starts with the script.
At Pinch Media, we believe the biggest mistake companies make with explainer videos is deciding the runtime before deciding what actually needs to be said. The best explainer scripts don’t try to squeeze 10 pounds of information into a 2-pound video.
They figure out what matters most, say it brilliantly, and get out.
What is the ideal length for an explainer video?
For most companies, 60–90 seconds is the sweet spot for an explainer video.
Here’s a practical breakdown:
| Explainer Video Length | Best For |
| 15–30 seconds | Quick concepts, social ads, simple products, awareness |
| 30–60 seconds | Simple product explanations, landing pages, paid ads |
| 60–90 seconds | Most B2B and B2C explainer videos |
| 90–120 seconds | More complicated products, platforms, or services |
| 2–3+ minutes | Detailed education, onboarding, demonstrations, training |
The important thing is that complexity should determine length, not a predetermined runtime.
A simple app might need 45 seconds.
A complicated software platform might genuinely need 2 minutes.
Trying to make both videos exactly 90 seconds simply because “that’s the ideal length” misses the point.
How many words is a 60-second explainer video?
A typical conversational voiceover runs at roughly 130–160 words per minute.
That means a rough script guide looks like this:
- 30 seconds: 65–80 words
- 60 seconds: 130–160 words
- 90 seconds: 195–240 words
- 2 minutes: 260–320 words
These are guidelines, not laws.
A fast, energetic brand can comfortably move through more words than a thoughtful financial or healthcare explanation.
The voice, visuals, pauses, animation, and complexity of the message all affect the final runtime.
Why shorter explainer videos often work better
Attention is expensive.
Every additional second gives the viewer another opportunity to leave.
That doesn’t mean every explainer video should be 30 seconds long. It means every second needs a job.
A strong explainer video typically needs to accomplish a few things:
1. Hook the viewer
Give them a reason to keep watching.
2. Identify the problem
Show that you understand the challenge they’re experiencing.
3. Introduce the solution
Explain what your product, service, or platform actually does.
4. Explain the value
Focus on outcomes and benefits, not a laundry list of features.
5. Tell them what to do next
Finish with a simple, specific call to action.
That’s a lot to accomplish.
Which is exactly why the script matters so much.
The real question isn’t “How long should my explainer video be?”
The better question is:
“How long does it take to communicate this idea clearly?”
That’s a very different question.
If your message can be understood in 45 seconds, don’t stretch it to 90.
If your audience genuinely needs 2 minutes to understand your product, don’t butcher the explanation trying to hit an arbitrary 60-second target.
Clarity beats brevity.
And brevity beats filler.
The biggest explainer video mistake: writing too much
Many companies approach an explainer video like a presentation.
They want to include:
Every feature.
Every benefit.
Every differentiator.
Every statistic.
Every integration.
Every testimonial.
Every award.
Every reason their company is amazing.
Then they wonder why their 90-second video has a 300-word script.
The problem isn’t the animator.
It’s the script.
A good explainer video isn’t a complete company brochure set to animation.
It’s a story with a purpose.
The script should ruthlessly prioritize what the viewer actually needs to understand.
A great explainer script is a compression exercise
Think about it this way:
Your company might have 10 minutes worth of things to say.
Your audience may only give you 90 seconds.
The job of a great scriptwriter is to find the most compelling 90 seconds.
That requires more than simply cutting sentences.
It requires strategy.
What is the actual problem?
What does the viewer care about?
What makes your solution different?
What can be demonstrated visually?
What information is unnecessary?
What can be combined?
What can be removed completely?
That’s where experienced explainer video scripting makes a massive difference.
Should an explainer video be 60 seconds or 90 seconds?
Usually, 60 seconds is ideal when the message is simple.
Choose around 90 seconds when the audience needs more context.
For example, a simple consumer product may need only a quick demonstration and value proposition.
A sophisticated B2B software platform may need to explain the problem, introduce multiple capabilities, demonstrate the workflow, and establish the business value.
Trying to force both into the same runtime can hurt the message.
The goal isn’t to make the video shorter.
The goal is to make it impossible to shorten without losing something important.
What makes an explainer video script effective?
A strong explainer script should sound less like a corporate brochure and more like a smart person explaining something to another smart person.
That means:
Lead with the problem.
People don’t inherently care about your product. They care about solving their problem.
Use simple language.
If a seven-word sentence can replace a 22-word corporate sentence, use the seven words.
Focus on outcomes.
“Automated workflow management” is a feature.
“Your team gets hours back every week” is a benefit.
Write for the ear.
A sentence that looks impressive on paper can sound terrible when spoken aloud.
Build visual opportunities into the writing.
The best explainer scripts don’t simply describe what is happening. They create moments that animation, motion graphics, live action, or visual storytelling can make more memorable.
How Pinch Media creates the right-length explainer video
At Pinch Media, we don’t start by asking:
“How many seconds do you want?”
We start with:
“What does your audience need to know?”
From there, we build the script around the story.
We identify the core message, eliminate unnecessary information, structure the narrative, and make sure every line earns its place.
Then we determine the appropriate runtime.
That might result in a 45-second video.
It might be 75 seconds.
It might be two minutes.
The right length is the length that makes the story work.
Because the secret to a great explainer video isn’t really animation.
It isn’t voiceover.
It isn’t even production.
It’s the writing.
A brilliant script makes everything downstream better: the storyboard, the visuals, the animation, the voiceover, the pacing, and ultimately the viewer’s understanding of your product.
How long should a B2B explainer video be?
For most B2B companies, 60–120 seconds is a practical range, depending on the complexity of the offering.
A straightforward service can often be explained in under 90 seconds.
A complex SaaS platform, technical product, or enterprise solution may justify a longer video.
The key is to avoid trying to explain the entire business.
An explainer video should have one primary job.
For example:
- Explain the product
- Introduce a new service
- Demonstrate a process
- Explain a complicated concept
- Drive a demo request
- Increase product understanding
- Support a sales presentation
One video can accomplish multiple things, but one primary objective keeps the script focused.
How long should an explainer video be for a website?
For a website homepage or product page, 60–90 seconds is often a strong target.
Visitors are typically scanning a page, trying to understand what a company does, and deciding whether it is worth exploring further.
A concise explainer can quickly answer the questions that matter most:
What is this?
Who is it for?
What problem does it solve?
Why should I care?
What should I do next?
That’s powerful real estate for a video.
How long should an explainer video be for social media?
Social content is a different animal.
A social explainer often works better when it gets to the point immediately, with versions ranging from 15–60 seconds depending on the platform, audience, and objective.
The first few seconds become especially important.
Don’t spend 10 seconds introducing your company before explaining why anyone should care.
Start with the interesting part.
Can an explainer video be too short?
Absolutely.
A 20-second video that leaves the viewer confused isn’t better than a 90-second video that makes the product instantly understandable.
Shorter is not automatically better.
Clearer is better.
A good explainer creates the feeling that the video moved quickly because the information was easy to understand, not because someone was racing through a voiceover at 200 words per minute.
Can an explainer video be too long?
Also yes.
Once the key message is understood, additional information can quickly become diminishing returns.
If the viewer already understands the problem, solution, and value proposition, another 45 seconds of product features may do more harm than good.
That’s where editing becomes storytelling.
Sometimes the smartest line in an explainer script is the one you delete.
Explainer Video Length FAQ
Is 60 seconds too short for an explainer video?
No. A 60-second explainer can communicate a surprisingly sophisticated message when the script is focused and the visuals do real storytelling.
Is 90 seconds too long for an explainer video?
Not necessarily. Ninety seconds is a common and useful length for products or services that require a little more context.
What is the best length for a B2B explainer video?
For many B2B companies, 60–120 seconds is a practical range. More complex products may require longer.
How many words should a 90-second explainer video have?
Approximately 195–240 spoken words, depending on voiceover pace and delivery.
What is more important: video length or script quality?
Script quality.
A perfectly timed bad script is still a bad video.
A well-written script creates clarity, pace, personality, and a strong foundation for the visual storytelling.
What is the best way to determine explainer video length?
Write the strongest possible script first, then determine the runtime based on how much information is genuinely required to communicate the idea clearly.
The Bottom Line
Most explainer videos should be around 60–90 seconds.
But the best explainer video isn’t the one that hits an arbitrary runtime.
It’s the one that makes the viewer understand your product, remember the message, and know what to do next.
And that starts long before animation begins.
It starts with the words.
At Pinch Media, we specialize in turning complicated ideas into smart, concise, engaging scripts that give explainer videos exactly the amount of time they need, and not a second more.
Because when the script is right, everything else gets easier.
