Why Explainer Video Length Matters
The length of your explainer video shapes how many people actually watch the whole thing and whether they bother to act afterwards. You’ve got to strike a balance: enough time to get your message across, but not so much that you bore everyone halfway through.
Impact on Viewer Engagement
You need to grab attention in the first five seconds, or people just click away. Research suggests engagement stays pretty steady until you hit two minutes, so a 90-second video keeps people watching about as well as a 30-second one.
Those opening seconds really matter. At Educational Voice, we usually start with a question that hits a nerve for the target audience. For a tech client in Belfast, we kicked off with, “Spending hours on manual data entry?” That line pulled people in straight away.
After two minutes, engagement tends to fall off a cliff. If you need to go longer—say, six to twelve minutes—make sure every moment is genuinely useful. Focus your video on answering one main question or fixing one clear problem, not cramming in everything you do.
Relationship Between Length and Retention
Viewer retention tells you how much of your video people actually watch. Half of consumers reckon one minute is the sweet spot for explainer videos, and a third prefer one to two minutes.
Where you post the video makes a big difference. Website videos can run longer since visitors already care about your business. A product demo on your homepage might suit 90 seconds, but a LinkedIn ad should probably stay under a minute.
Michelle Connolly, founder of Educational Voice, says, “We track retention data for every client project in Northern Ireland and across the UK, and the pattern is clear: videos that front-load the main benefit in the first 15 seconds consistently outperform those that build up slowly.”
Video analytics show exactly where people lose interest. If most viewers drop off at 45 seconds, that part of your video needs a rethink. We use this info to tweak scripts and make sure your main message lands before people tune out.
Influence on Conversion Rates
Shorter videos usually lead to more people seeing your call to action. If viewers leave before that point, you’re basically wasting a chance to win them over.
The best explainer video length depends on where your audience finds it. For paid ads, 30 seconds works well. For your website, aim for 60 to 90 seconds. If you’re explaining something detailed, you can stretch to two, maybe two and a half minutes.
Think about what your video is for:
- Social media ads: 15-30 seconds
- Homepage explainers: 60-90 seconds
- Product demonstrations: 90-120 seconds
- Tutorial content: 2-5 minutes
We helped a UK e-commerce client boost conversion rates by 34% just by cutting their homepage video from three minutes to 75 seconds. The shorter version stuck to their main selling point and ditched the laundry list of features.
Try out different lengths and see what your audience actually responds to. Start with 90 seconds as a baseline, then tweak based on real-world results.
Ideal Explainer Video Length
Most explainer videos work best between 60 and 90 seconds. That’s usually enough time to get your point across without losing people’s attention.
Shorter 30-second versions fit well for social media, while the standard lengths let you balance giving information with keeping people interested.
Standard Durations: 30, 60, 90 Seconds
You’ll find three main length choices. A 30-second video is perfect for quick product launches or social ads where you need to get straight to the point.
60-second videos work well on your homepage. You can introduce a problem, show your solution, and wrap up with a call to action. This format suits most explainer videos focused on turning visitors into leads.
90-second videos give you space for more detail. You can mention extra benefits or show how your product solves a few problems. This length fits service pages, where people already want more information.
At Educational Voice, we make videos in all these lengths depending on what our clients need. We made a 90-second animation for a Belfast software company to explain three main features, and a 30-second promo for a retail client’s Instagram campaign.
Why 60-90 Seconds Is Most Common
Sixty to ninety seconds tends to work best because it matches how long people actually pay attention. Videos in this range hold viewers without overloading them.
You can fit about 150-225 words in that time, which is enough for your value proposition, main benefits, and a clear next step.
UK businesses find this length gets results. It lets you connect emotionally, show off your product’s value, and nudge people to act. Go too short and you might leave out something important. Go too long and you risk losing people before your call to action.
Michelle Connolly from Educational Voice puts it like this: “When clients ask how long their explainer video should be, I always start by asking what problem they’re solving and for whom. The answer usually points to 60-90 seconds because that’s the sweet spot where clarity meets completion rates.”
Balancing Clarity With Conciseness
Your video needs to be long enough to say what matters, but short enough that people stick around. Focus on one main idea and three or four supporting points, not every single feature.
Open with your core message in the first 10 seconds. Businesses in Northern Ireland sometimes try to cram too much into their first explainer, which just muddles things.
Here’s a rough breakdown for a 75-second video:
- Problem introduction: 8 seconds
- Solution reveal: 8 seconds
- Benefits explanation: 45 seconds
- Call to action: 14 seconds
Cut out fluff in your script. Say “We help businesses” instead of “We provide businesses with solutions that help them.” Let your visuals do some of the explaining, especially with animation.
Read your script out loud at a normal pace. If it sounds rushed, you’re squeezing in too much. Stick to what supports your main goal and lose the rest.
Choosing the Right Video Length by Purpose
The reason for your explainer video matters more than anything else when picking the right length. A 15-second teaser does a totally different job to a 3-minute training video. If you get the match wrong, people either get bored or don’t get enough info.
Brand Awareness and Teasers
Brand awareness videos should stick to 15 to 30 seconds. You’re fighting for attention in busy social feeds, so you want people to notice your brand—not learn your whole story.
At Educational Voice, we make brand awareness content for Belfast clients that focuses on one memorable idea. We recently made a 22-second company culture video showing a client’s team in action with three quick benefits as text overlays.
Keep these under 30 seconds for Instagram and LinkedIn. Use bold visuals in the first three seconds because that’s when most viewers decide whether to keep watching. Show your logo early so people remember who you are, even if they don’t stick around.
A teaser should leave people curious, not overwhelmed with details.
Product Demos and Feature Introductions
Product demos need 60 to 90 seconds on your homepage, but you can go up to 2 minutes on product pages where people are already interested. The main thing is, homepage visitors are just browsing, while product page visitors are actively checking you out.
We created a product demo for a Northern Ireland software company that ran 85 seconds. We started with the main problem, showed three key features in 50 seconds, and finished with a clear call to action. This length for detailed benefits let us show off the interface without losing people.
For new feature updates, keep videos at 45 to 60 seconds. Your current customers know your product, so just highlight what’s new and why it matters.
Use screen recordings for SaaS products and show real workflows your UK and Irish clients will recognise.
Training and Onboarding Content
Training videos work best at 2 to 5 minutes per topic. Break up complicated processes into separate videos instead of making one long tutorial. Each video should cover one task that a new user can finish right after watching.
At Educational Voice, we build onboarding content as a series of short videos. One client needed to explain their project management tool to new team members across Ireland, so we made six videos averaging 3 minutes each. That way, users can watch only what they need instead of slogging through a 20-minute overview.
Michelle Connolly says, “When we script training content for clients, we aim for one clear learning outcome per video with a maximum of four steps to complete that outcome.”
Use bullet points or numbered lists in your training videos to show progress. Add timestamps if your video is over 3 minutes so viewers can jump to what they need. Each training video should answer one question properly, not skim several topics.
Make a separate training video for each feature or process. That way, employees can revisit just what they need without hunting through a long video.
Platform-Specific Length Guidelines
Different platforms call for different video lengths. For Facebook and Instagram ads, stick to 15 seconds or less. YouTube pre-rolls work best at 6 to 15 seconds, and website explainer videos do well at 60 to 90 seconds.
Facebook and Instagram Ads
Your explainer video length for Facebook ads should never go over 15 seconds. People scroll fast, and you’ve only got about three seconds to grab their attention before they move on.
We always add subtitles to these ads at Educational Voice, since most viewers watch with the sound off. Your video has to show the main benefit without audio, using big text overlays that look good on a phone.
Michelle Connolly explains, “When producing 15-second ads for clients across Belfast and Northern Ireland, we front-load the value proposition in the first three seconds, then reinforce it with visual proof points before the call to action.”
Key elements for 15-second social ads:
- Hook within 3 seconds
- One clear benefit
- Mobile-friendly text size
- Strong call to action
- Works without sound
Design your animation for silent viewing from the start. Don’t just tack on captions at the end.
YouTube Pre-Roll and Unskippable Ads
YouTube pre-roll ads come in two main formats, and that shapes how long your video should be. Skippable ads let viewers skip after 5 seconds, but unskippable ads make everyone watch the whole thing.
For skippable pre-roll, aim for 15 to 25 seconds. You need to hit your main message within the first 6 seconds, since that’s when viewers can skip. At our Belfast studio, we treat those opening 6 seconds as a stand-alone micro-message, then use the rest of the time to add detail for anyone who sticks around.
Unskippable ad formats on YouTube usually last 6 to 15 seconds. You get guaranteed eyes on your content, but remember, viewers can’t escape. Make those seconds count with something genuinely valuable right away.
Try out different lengths within these ranges and see what actually works for your audience and product.
Website and Landing Pages
Your homepage explainer video should last 60 to 90 seconds. People landing there already want to know about your business, so you can explain your main points, show what makes you different, and guide them to act—all without dragging things out.
On service or product pages, you can go up to 2 minutes. If someone’s clicked through to these pages on your UK or Irish site, they’re more engaged and ready for the details.
At Educational Voice, we split longer website videos into clear sections: a 5-second problem, a 10-second solution, 40 seconds breaking down benefits, and a 10-second call to action. This approach keeps things moving.
Website video length by page type:
| Page Type | Recommended Length | Why |
|---|---|---|
| Homepage | 60-90 seconds | Balance detail with broad appeal |
| Service pages | 90-120 seconds | Higher intent justifies depth |
| Product demos | 2-5 minutes | Functionality needs full explanation |
Put your video above the fold on landing pages so visitors see it right away.
Adapting Length Based on Audience Attention
Match your video length to how much the viewers already care. People who search for your content want a different pace than those who just stumble across it.
Chance Viewings vs Opt-In Audiences
Chance viewings need to grab attention straight away. If your explainer pops up as a pre-roll ad or in a social media feed, you’re dealing with uncommitted audiences who might leave in seconds. Stick to 30 to 60 seconds max in these cases.
At Educational Voice, we make different versions for Belfast and UK clients based on where the video will show up. A 30-second cut works for paid social ads, while a 90-second version fits website landing pages where visitors want more info.
Opt-in audiences give you more freedom. Training videos, webinars, and tutorials can go past two minutes because people have chosen to watch. They’ve signed up or clicked play on purpose.
“When clients in Belfast ask about video length, I always say, think about how committed the viewer is, then plan the duration,” says Michelle Connolly, founder of Educational Voice.
Chance viewing contexts:
- Pre-roll adverts (15-30 seconds)
- Social media feeds (30-45 seconds)
- Homepage hero videos (45-60 seconds)
Opt-in viewing contexts:
- Product tutorials (2-3 minutes)
- Training modules (3-5 minutes)
- Educational webinars (5+ minutes)
Match your video length to where people find you and how interested they already are.
Retaining Attention in the First 5 Seconds
The first 5 seconds decide if viewers stay or click away. You need to hook viewers right from the start, no matter how long the video is.
Try starting with a question that hits your audience’s pain point. For a Belfast software company, we started with “Spending hours on manual data entry?” instead of a boring intro. That problem was familiar, so people paid attention.
You can also show a situation your viewers know well. Highlight the frustration or the daily hassle they face. Northern Ireland businesses, in our experience, react well to real, relatable scenarios instead of stiff corporate talk.
Skip the logos and company history in those critical opening moments. Your brand matters, but only after you’ve earned their attention. Bring in credentials later, once you’ve shown you understand their needs.
Put value up front. If your explainer is 60 seconds, those first five seconds are the most important. Treat them like prime property.
Test your opening with people outside your company before you lock it in. If they can’t say why the video matters in five seconds, tweak your hook until it’s clear and grabs them.
Adjusting for Message Complexity
The complexity of what you’re saying decides how long your explainer video should be. A simple product feature might only need 30 seconds, but a technical B2B solution could need two minutes or more.
Simple Messages vs Detailed Explanations
Short videos work best for simple messages. If you’re launching a single feature or pushing one clear benefit, 30 to 60 seconds is usually enough.
Your animated explainer video should fit the amount of information your audience needs. Explaining a food delivery app’s new checkout takes much less time than walking through enterprise software.
At Educational Voice, we often tell Belfast clients that a 60-second video is perfect for basic product intros. You can lay out the problem, your solution, and a call to action without overloading viewers.
Count your main points. If you have one key benefit and two extra features, 60 seconds is fine. If you need to cover four or five ideas, you’ll need a bit more time.
When Longer Videos Are Justified
Technical products, B2B services, and complex processes need longer explainer videos, usually two to three minutes. Your audience expects more detail when they’re making big decisions or learning a tricky system.
“When a Northern Ireland manufacturing client needs to explain a multi-step industrial process, we plan for 90 to 120 seconds. Rushing technical details just confuses people,” says Michelle Connolly, founder of Educational Voice.
Longer videos make sense when your message is more complicated. SaaS platforms with lots of features, medical devices showing procedures, or financial firms explaining steps all benefit from extra time.
People who are already interested will watch detailed content. Plan your script so every second counts and doesn’t just fill space.
Video Length and the Buyer’s Journey
Different stages in the buyer’s journey call for different video lengths. Awareness stage videos work best at 30 seconds or less, but consideration and decision stage content can go up to 2.5 minutes when people want the details.
Awareness Stage Videos
Keep awareness stage videos under 30 seconds. At this point, people are just realising they have a problem. They’re not ready for a deep dive.
These short videos are perfect for social media, where people scroll fast. A Belfast software company might use a 20-second animation to highlight a common business pain point without even naming their product. The aim is to spark curiosity, not sell.
“When we make awareness content for clients in Northern Ireland and the UK, we focus on one clear problem that hits home right away,” says Michelle Connolly, founder of Educational Voice. “These 15 to 30-second animations have to catch people in the first three seconds or they’re gone.”
Video marketing statistics show viewers drop off fast after two minutes, so keep it brief. Use bold text and lively visuals to hold attention.
Consideration and Decision Stage Videos
Consideration and decision stage videos can be longer because viewers are actively comparing options. At Educational Voice, we usually make 60 to 90-second videos for consideration and stretch to 2 or 2.5 minutes for decision stage content.
People at the consideration stage want to compare. They’ll watch a 90-second animation that explains your service and what sets it apart. A manufacturing company in Ireland might use this length to show their process advantages.
Decision stage viewers want all the details before buying. They’ll spend 2.5 minutes on feature breakdowns, case studies, and step-by-step walkthroughs. We recently made a 2-minute explainer for a Belfast fintech firm that covered their entire onboarding process.
The ideal explainer video length depends on how committed your viewers are. Break up longer videos with chapters or visual cues to keep people watching. Use real numbers, testimonials, and examples instead of vague claims.
Build your video marketing strategy with different versions for each stage of the buyer journey, then see which works best with your audience.
Video Format and Its Impact on Length
The format you pick changes how long your explainer video should be. Animated videos usually work best at 60-90 seconds, but live-action and hybrid videos can go longer if the product is complex.
Animated Explainer Videos
Animated explainer videos hit the sweet spot at 60 to 90 seconds for most business needs. That gives you enough time to explain what you do without losing people.
At Educational Voice, we create 2D animations for clients across Belfast and the UK. Ninety seconds lets you fit in about 225 words—enough for the problem, your solution, benefits, and a call to action.
The great thing about 2D vs 3D animation is that you control every detail. You can show ideas you can’t film in real life. You also save time since you don’t need lengthy setups.
For social media, trim your animated content down to 15-30 seconds. Instagram and LinkedIn users scroll fast, so you need to grab them instantly.
“When a Belfast retail client wanted to explain their loyalty programme, we made a 75-second 2D animation. It bumped their website conversion rate by 34% in just two months,” says Michelle Connolly, founder of Educational Voice.
If you’re new, keep your first animated explainer to 60-90 seconds. That gives you space to introduce your brand without dragging on.
Live-Action and Hybrid Formats
Live-action videos can run a bit longer than animation because people connect with real faces. You can go up to 2-3 minutes for detailed product demos or testimonials.
Animation vs live action comes with timing challenges. Live-action usually needs more setup and context, which adds to the runtime.
Hybrid formats mix live-action with animated graphics, giving you the best of both. Use animation to highlight features, but keep that human touch.
For screencast tutorials, especially for software, 3-5 minutes is fine. Viewers searching for these will stick around if you’re solving their problem.
Test different video lengths with your audience before you go big on production.
Best Practices to Maximise Engagement
If you want viewers to stick around for your explainer video, you need to plan each second from the opening frame to the final call to action. Good scripting, eye-catching visuals, and a clear CTA all work together to keep people watching and actually drive them to act.
Scripting for Conciseness
Every sentence in your script should deliver value. Don’t waste a moment. At Educational Voice, we stick to about 2.5 words per second when writing scripts. This approach helps us plan the perfect video length and saves you from frustrating re-recording sessions.
Start with one main message, then pick three or four supporting points at most. Businesses in Belfast and across the UK often want to showcase every single feature, but viewers remember more when you focus on specific benefits instead of listing every capability.
Write short, active sentences. Cut out adjectives and filler that just pad the word count. For example, instead of “Our innovative platform helps businesses effectively manage their complex workflows,” just say, “Our platform manages your workflows in three clicks.”
Read your script aloud at a normal pace. If you’re struggling to breathe or the words trip you up, it’s time to simplify. For a 60-second video, aim for about 150 words. It’s surprisingly tough, but it forces you to be sharp.
Using Visual Hooks
The first three seconds really decide if viewers stick around or just scroll on, especially on platforms where attention spans are tiny. Your visuals should show the viewer’s problem or use an unexpected image to spark curiosity right away.
We design different openings for different platforms. For Facebook and Instagram ads aimed at businesses in Northern Ireland and the wider UK, we use visuals that work even without sound. Bold text overlays and punchy motion graphics grab attention instantly.
“The hook isn’t just about being flashy or clever, it’s about showing your viewer that you understand their specific pain point within the first five seconds,” says Michelle Connolly, founder of Educational Voice.
Good visual hooks show the problem happening, highlight a surprising stat with animated numbers, or use a character that mirrors your audience. When we made an explainer for a Belfast fintech company, we started with an animated character drowning in paperwork—small business owners really related to that.
Don’t open with your logo or generic stock footage. You need to earn attention before you reveal who you are.
Optimising for Call to Action
Your CTA deserves a full ten seconds at the end of your video, with your brand logo clearly visible. This pause gives viewers time to absorb your message and figure out what to do next.
Keep your CTA specific and stick to one action. Instead of “Learn more” or “Visit our website,” try “Start your free trial” or “Book your demo today.” Too many options and people end up doing nothing.
Put your CTA in both the voiceover and on screen using clickable buttons or clear text. For videos on your website, we usually add annotation buttons that go straight to your landing page or contact form.
Test different CTAs depending on where your video appears in the buyer’s journey. Awareness-stage ads might say “See how it works,” while decision-stage videos on your service pages should use something like “Get started now” or “Request pricing.”
Before you call your video finished, make sure your CTA fits the next logical step in your sales process. The landing page should deliver exactly what your video promised.
Common Mistakes in Determining Explainer Video Length
Some businesses chop their videos down too much, worried about losing viewers. Others cram in way too much detail, ignoring the platform’s rules.
Assuming Shorter Is Always Better
You might think that cutting your explainer video down to 15 seconds will keep everyone watching. Actually, that can backfire. A video that’s too short can’t introduce your brand, explain your value, or build any real connection—especially if viewers don’t know you yet.
Brand recognition matters when you decide how long an explainer video should be. If you’re MailChimp, a 14-second announcement works because everyone already knows you. If you’re a Belfast startup with a new product, you need 60 to 90 seconds to introduce yourself and give people a reason to care.
We often have clients ask for 30-second videos when they actually need twice that. If you’re new, those extra seconds help you build trust and get your message across. Rush it, and people won’t even remember you.
“The biggest mistake we see from businesses across Northern Ireland is cutting videos short before they’ve actually communicated their core value proposition,” says Michelle Connolly, founder of Educational Voice. “Your animation should be long enough to do its job, not just short enough to avoid drop-off.”
Give your first explainer video enough time to work. Don’t just cut for the sake of it.
Overloading Videos With Information
Trying to squeeze every feature into your explainer video just makes it confusing. People won’t remember anything if you overload them.
I’ve watched loads of 90-second videos try to cover eight product features. You’re better off focusing on one main idea and a few key benefits. When you pile in too much, viewers can’t tell what matters. They leave without remembering a thing.
In real production, we’ll sometimes get a 250-word script for a 60-second video. That’s nearly three words per second, and it’s just too fast for anyone to follow. The standard rule is 2.5 words per second for a reason.
Focus always beats packing in everything. Highlight what makes you different. Save the deep dives for later, when people actually want more info.
Cut the extras and your explainer video length will work better.
Neglecting Platform Guidelines
Different platforms want different video lengths. Yet some businesses make one video and post it everywhere, expecting the same results.
A 90-second explainer might be perfect for your homepage. But as a Facebook ad, it’ll flop—15 seconds is the sweet spot there. Instagram ads need an even snappier hook, with just three seconds to get noticed. YouTube pre-rolls do best at six seconds, and LinkedIn prefers videos under 30 seconds for brand awareness.
Platform algorithms and user habits aren’t just suggestions. They decide if your content gets seen. Businesses in the UK and Ireland who ignore this end up wasting money on videos that never reach anyone.
I always suggest making several versions of your animation, not just one. Put your main 60-second explainer on your website, then edit shorter versions with platform-specific hooks for social media.
Match your explainer video length to the platform, and you’ll see better engagement everywhere.
Using Data to Refine Video Length
Your video analytics show exactly how people interact with your content. Testing different lengths and looking at real results helps you make better choices for your next production. By measuring completion rates and engagement, you can find the best duration for your audience and platform.
Interpreting Video Analytics
Analytics reveal where viewers drop off, which tells you if your video drags on too long or if certain sections lose their interest. The key numbers are completion rate, average watch time, and drop-off points.
Check your completion rate first. If less than half your viewers finish, your video might be too long. Look for the exact timestamp where most people leave. That’s your trouble spot.
We track these things for every animation at Educational Voice. When we made a 90-second explainer for a Belfast tech company, analytics showed 40% of viewers left at the 60-second mark. We cut the video to 75 seconds and reworked the content. Completion rate jumped to 68%.
Watch engagement metrics like click-throughs on your CTA. A shorter video with a high finish rate will usually beat a longer one that loses viewers. “Track your drop-off points within the first week of publishing, then adjust your next video accordingly rather than waiting months to gather data,” says Michelle Connolly, founder of Educational Voice.
Testing Different Durations for Results
Split testing video lengths across platforms gives you real proof of what works. Make two versions of the same explainer at different lengths and show them to the same audience side by side.
Test a 60-second version against a 90-second one on your homepage. Watch which one brings in more conversions over two weeks. The numbers will tell you if the extra 30 seconds help or hurt.
On social media, try 15-second and 30-second versions of the same message. Track view counts, engagement, and clicks. A Northern Ireland software company we worked with found their 15-second LinkedIn ads got three times more clicks than the 30-second ones, even though the longer video gave more detail.
Run your tests for at least two weeks to get enough data. Keep a simple table showing length, completion rate, and conversion rate. Use what you learn to shape your next project and tweak your explainer video length strategy based on real results, not just guesses.
Real-World Examples of Effective Explainer Video Durations
Explainer videos work best when the length matches the purpose. Companies get better engagement when video duration fits their goals and audience.
Short Explainer Video Case Studies
A 30-second explainer video works brilliantly for social media ads. For our Belfast clients, we often suggest 15 to 30 seconds for Instagram and Facebook. These short videos focus on one clear benefit and end with a strong call to action.
MailChimp does this well with their product announcement videos. They use their brand recognition to share new feature updates in under 20 seconds. No need for long intros because their audience already trusts them.
For Northern Ireland businesses running awareness campaigns, I always recommend keeping those first videos short. One retail client saw their click-through rates jump by 43% after switching from 90-second homepage videos to punchy 30-second ads.
The trick is to pack value into a short time without losing clarity.
In-Depth Explainer Video Success Stories
Software and SaaS companies often get better results with longer explainer videos—think two to five minutes. These longer formats give you room for proper feature demonstrations and walkthroughs so users can really understand your tool.
“When a UK fintech client needed to explain their new compliance software, we created a 3.5-minute explainer that walked through actual user scenarios, and their demo requests increased by 67% within the first month,” says Michelle Connolly, founder of Educational Voice.
Ahrefs puts out detailed product tutorials that run from three to seven minutes. Their audience wants this depth because they’re past the intro stage and need more info before buying.
Aim your longer videos at users who are ready to consider or decide. We’ve seen that service page videos can go past two minutes if visitors have already clicked through from your homepage—they’re genuinely interested and want details.
Frequently Asked Questions
Businesses often ask the same things when they’re planning explainer videos. Timing and length come up a lot.
Research suggests that videos between 60 and 90 seconds usually work best. Still, your chosen platform and how tricky the topic is can shift those numbers.
What is the optimal length for an explainer video to make sure you keep your audience engaged?
Most explainer videos land in the 60 to 90-second range. That gives you enough time to explain what you offer, and people tend to stick around for it.
Wistia looked at over a billion video plays and found engagement stays steady up to two minutes. After that, most viewers drop off pretty sharply.
You don’t have to hit exactly 90 seconds, but it’s a good benchmark to aim for.
At Educational Voice, we’ve made hundreds of explainer videos for businesses in Belfast and across Northern Ireland. We always match the animation length to the complexity of what needs explaining, not just an arbitrary time limit.
Michelle Connolly, who founded Educational Voice, puts it this way: “When a Belfast fintech client wanted to explain their mobile banking app, we made a 75-second animation. Their website conversions jumped by 34%. That length let us tackle three main pain points without losing attention.”
For general awareness or homepage videos, stick to 60 to 90 seconds. You’ll see higher completion rates that way.
How does video duration affect retention rates?
Shorter videos usually get watched all the way through more often, which boosts your return on investment. A 30-second video gets more people to your call-to-action than something that drags on for three minutes.
Surveys show half of viewers prefer 1-minute explainer videos, and about a third like videos between one and two minutes. Only a small chunk want videos under a minute. So, most viewers will watch a full minute if it actually gives them something worthwhile.
The type of video matters too. Pre-roll ads on YouTube need to grab attention in five seconds, or people just skip them. Product demos on your website can run a bit longer because visitors already want to know more.
We track completion rates for our Belfast clients at Educational Voice and usually see 80% or better on videos under 90 seconds. Once videos go past two minutes, retention often drops to 50% or less—unless the content really grabs people.
Think about where your video will live before you settle on a length. Platform and audience intent both play a part in how long people stick around.
Can the complexity of the topic dictate the length of an explainer video?
If your topic is complex, you might need a longer video, but only if that extra time helps the viewer understand. Padding a video just because the subject feels tricky doesn’t help anyone.
Training videos and tutorials are different because viewers actually want to learn. These can stretch past two minutes since the audience has already committed to understanding the material. Tutorial videos can take as long as needed to walk through the steps.
We worked with a UK healthcare provider to explain a new patient portal. We had to cover security, registration, and booking appointments. The animation ran for 2 minutes and 15 seconds, broken into clear chapters, because patients needed all the info before using the system.
For complex B2B products or services, you might need 2 to 2.5 minutes if you need to go deeper. That lets you cover technical details while keeping the story clear.
If your topic is really complex, break it into chapters or a series of shorter videos. One long video can test anyone’s patience.
What are the best practices for deciding video length on social media platforms?
Every social platform has its own quirks, so you’ll want to adapt your video length. Instagram and TikTok like videos under 60 seconds. YouTube viewers are usually fine with longer stuff.
On social media, the first 3 to 5 seconds decide if people keep watching or just scroll. Your animation needs to grab attention straight away, maybe with a question or a bold visual. The total length matters less than those first few seconds.
Facebook videos work best between 60 and 90 seconds. That gives you time to tell a story, but you don’t lose people who are scrolling quickly. LinkedIn audiences, especially for B2B content, will stick with videos up to two minutes if they see professional value.
We often adapt explainer videos for our Belfast clients to fit different platforms. A 90-second hero video for your website might become a 30-second teaser for Instagram or a 15-second highlight for TikTok. Each version keeps your core message but fits the platform.
