How Long Should an Explainer Video Be, and What Does Each Length Suit?

Ask ten studios how long an explainer should run and you will hear “about a minute” from most of them. That is a sensible default, but it is not the full answer. How long should an explainer video be depends on where it will play, how much the viewer already knows, and the single action you want them to take. A 60-second video that works beautifully on a product page can be far too slow as a feed ad, and far too thin as a training module.

This guide breaks down what each length suits, how to plan the script for it, and how to get several lengths from one project. It is the same thinking we use when scoping explainer video production at Omebly.

Quick answer: For a website or product page, 60 to 90 seconds is usually right. For social and paid ads, 15 to 30 seconds works better. For sales follow-ups, onboarding and training, 90 seconds to 3 minutes is fine, because the viewer has already chosen to learn. Pick the length from where the video plays, then write to fit it.

Why there is no single right explainer video length

An explainer is judged on one thing: did the viewer understand enough to take the next step? Length is simply a budget of attention, and that budget changes with context.

• Cold viewers (someone scrolling a feed) give you a few seconds before deciding whether to stay. You need a hook immediately and very little detail.
• Warm viewers (someone who clicked through to your product page) are curious. They will give you a minute if the first few seconds show you understand their problem.
• Committed viewers (a new customer in onboarding, or staff in training) actively want the information. They will watch several minutes, as long as every minute is useful.

So rather than asking “what is the ideal explainer video length?”, ask “who is watching, where, and what do they already know?”

How long should an explainer video be? Lengths and what each suits

Length	Voice-over words (approx.)	Best for	What fits in it
6–15 seconds	0–35	Feed ads, Stories, bumper ads, retargeting	One hook, one benefit, one call to action
15–30 seconds	35–70	Social ads, landing page hero loops, app store previews	Problem, solution, one proof point, call to action
60 seconds	130–150	Homepage, product page, pitch deck opener	Problem, solution, how it works in three steps, call to action
90 seconds	190–220	Detailed product or service, B2B products with a longer buying cycle	The 60-second structure plus a short use case or objection answered
2–3 minutes	260–420	Sales follow-ups, demo pages, onboarding	A walkthrough of a feature or workflow
3 minutes plus	Varies	Training and internal processes	Step-by-step instruction, often split into chapters

Word counts assume a calm voice-over at roughly 130–150 words a minute. Hindi and Arabic reads can run a little longer or shorter for the same meaning, so always time a read-aloud in each language you need.

15 seconds and under: for the feed

Short explainers are really ads. They do not explain everything; they make someone curious enough to tap. If you are buying video ads on Google, note that formats have their own length rules: Google’s video ad formats guide sets bumper ads at six seconds maximum, for example. Write for sound-off viewing, with the message carried by on-screen text.

30 seconds: the workhorse

Thirty seconds is long enough to name the problem, show your product as the answer and give one reason to believe it. It suits paid social, landing page hero sections and app previews. It is also the most common cut-down of a longer website video.

60 to 90 seconds: the website explainer

This is the classic length for a homepage or product page. The viewer has chosen to press play, so you can show how the product works in two or three steps. Go towards 90 seconds only if your product genuinely needs it, for instance software with a workflow buyers have not seen before, or a service with several stages.

2 minutes and longer: when the viewer already wants detail

Longer videos work in sales follow-up emails, on demo pages, inside onboarding and for training. Here the job shifts from persuading to teaching. Split long content into chapters or a short series so viewers can find the part they need.

How to choose the right length for your explainer

Work through these steps before anyone writes a script.

1. List every place the video will appear. Homepage, product page, Meta ads, sales emails, trade-show screen. Each place has its own natural length.
2. Pick the main placement. Usually the website. That sets the length of the master version.
3. Write the one-sentence goal. “After watching, [audience] will understand [one message] and will [one action].” If you cannot fit it into one sentence, you probably need two videos.
4. Count the steps you need to show. Three steps fit comfortably in 60 seconds. Five or six steps push you towards 90 seconds or a short series.
5. Plan the cut-downs now. Mark which lines of the script survive in a 30-second and a 15-second version. It is far cheaper to plan this at script stage than to re-edit later.
6. Read the script aloud with a stopwatch. If it runs long, cut words, not pauses. Rushed narration is the most common reason explainers feel cheap.

One project, several lengths

You rarely need just one length. A typical set looks like this:

• Master version: 60 to 90 seconds, landscape 16:9, for the website and sales emails.
• Ad cut-down: 15 to 30 seconds, square or vertical, for paid social.
• Teaser: 6 to 10 seconds, vertical, for Stories and retargeting.

The trick is to design the master with cut-downs in mind. Keep the hook, the core benefit and the call to action as self-contained scenes, so an editor can lift them out cleanly. Frame key visuals so they still read when cropped to 9:16. Captions should be burned in on the social versions, because many people watch with the sound off; the W3C’s guidance on captions explains why they help every viewer, not only those with hearing loss.

If your main goal is paid social rather than your website, it may be better to start from ad creative instead of an explainer. Our motion graphics ads work is built around short hooks and several variations to test.

Signs your explainer is too long (or too short)

Too long

• The script opens with your company history or your logo.
• You list features instead of showing one benefit at a time.
• The narrator sounds rushed because the word count is too high for the length.
• Retention reports show a steep drop in the first quarter of the video.
• Stakeholders added “just one more point” in each review round.

Too short

• Viewers reach the end still unsure what the product does.
• The call to action appears before the viewer has seen why they should care.
• Sales teams keep pausing the video to explain what it skipped.
• A 15-second cut is being used on a page where people expected detail.

Mistakes to avoid when deciding explainer length

1. Choosing length before the goal. “We want a two-minute video” is a budget, not a brief. Start from the audience and the action.
2. Cramming several products into one video. One message per video. A short overview plus separate feature videos is clearer.
3. Forgetting language versions. If you need Hindi or Arabic as well as English, time each read, since one long script multiplied across languages adds up.
4. Leaving ad cut-downs to the end. Scenes designed for 16:9 often crop badly to vertical.
5. Ignoring where it sits on the page. A video buried at the bottom of a page gets fewer plays whatever its length. Place it near the top, with a clear thumbnail.

Explainer length checklist

• Every placement listed, with its natural length
• Main placement chosen and master length set
• One audience, one message and one action written down
• Steps counted (three for 60 seconds is comfortable)
• Script word count matches the target length
• Read aloud and timed in each language
• 30-second and 15-second lines marked in the script
• Key visuals framed to survive a vertical crop
• Captions planned for sound-off viewing
• Retention reports checked after launch

Not sure whether your story needs flat 2D animation or a 3D product shot? Our comparison of explainer videos vs 3D product animation covers that choice.

How Omebly can help

Our explainer video service starts with exactly this conversation: where the video will play, who will watch it and what they should do next. From there we write and time the script, build the storyboard, design custom illustration in your brand, and animate in 2D, or in 3D where the story needs it. Professional voice-over in English, Hindi, Arabic and other languages, captions and cut-downs for web, ads and social are part of the plan from the start, not an afterthought. Explainers sit within our wider animation design service, and start from $900 for a 30-second video, with a fixed written quote after a free consultation.

We work with brands in Kolkata, Downtown Dubai and further afield, on calls in your time zone. Tell us what your video needs to explain through the contact page or on WhatsApp at +91 70444 33991.

Decide where your explainer will play first, and the right length usually decides itself.
