“How long should our video be?” is one of the first questions every brand asks us — and the honest answer is: it depends on where it’s going and what it’s for. There’s no single perfect video length. A TikTok ad and a corporate explainer have completely different jobs, audiences and attention spans. This guide gives you clear, practical rules of thumb for video length by platform and goal, so you can brief the right cut instead of guessing.
The golden rule: as long as it needs to be, no longer
Before any platform-specific numbers, internalise this: the right video length is the shortest one that does the job well. Every extra second is a chance for the viewer to drop off. If your message lands in 20 seconds, don’t pad it to 60. If it genuinely needs two minutes to be useful, don’t crush it into 30 and lose the substance.
People don’t abandon videos because they’re long; they abandon them because they’re boring or slow. A gripping two-minute video beats a dull 30-second one. So treat the ranges below as starting points, not laws — and always cut anything that isn’t earning its place.
Video length by platform
Each platform has its own norms and audience behaviour. Here’s where to aim.
TikTok
Short and punchy wins, though TikTok now supports longer videos too. For most brand content, aim for roughly 15–34 seconds, hooking viewers in the first second or two. Longer storytelling videos can work once you’ve built an audience that trusts you, but newcomers should keep it tight.
Instagram Reels
Similar to TikTok — short and snappy. Around 15–30 seconds is a reliable zone for strong completion rates. The first frame has to stop the scroll.
YouTube
This depends heavily on format. YouTube Shorts follow the short-form rules (under a minute). Standard YouTube videos can and should be longer when the content justifies it — explainers, tutorials and stories often run several minutes, because viewers arrive expecting depth. Watch time matters more than raw length here.
Facebook and LinkedIn
Feed videos should be brief — often around 30–60 seconds — since people scroll fast. On LinkedIn, professional and informative short videos tend to perform best for B2B audiences.
Paid ads
For social ad placements, shorter is usually safer — many high-performing video ads sit in the 15–30 second range, with the core message and brand front-loaded in the opening seconds in case people scroll on.
Video length by goal
Platform is only half the picture; what the video is trying to achieve matters just as much.
- Brand awareness / social ads: short and memorable — often 15–30 seconds. Make the point fast and brand it early.
- Product explainer / how-to: long enough to be genuinely clear, frequently around 1–2 minutes. Clarity beats brevity here.
- Testimonials / case studies: typically 1–2 minutes — enough to tell a credible story without dragging.
- Corporate / company profile: often around 1.5–2.5 minutes for the main cut, with shorter teaser edits for social.
- Event highlights: usually 1–2 minutes to capture energy without losing the viewer.
A smart move is to film once and cut multiple lengths — a longer hero video for your website plus several short clips for social. We plan this into our videography projects so one shoot feeds your whole channel mix instead of a single placement. You can see how that plays out across formats in our work.
What actually matters more than length
If you take one thing away: the hook matters more than the runtime. Most drop-off happens in the first few seconds. Whatever the video length, you have to earn attention immediately.
- Front-load the value. Lead with the most interesting thing, not a slow logo animation. Especially in ads, get your brand and message in early.
- Keep the pace up. Tight editing, no dead air. A faster cut holds attention regardless of total length.
- Design for sound-off. Most social video is watched on mute — captions and clear visuals carry the message.
- End with a clear next step. Tell viewers exactly what to do, however short the video.
The Singapore context
Singapore audiences are mobile-first and scroll fast across TikTok, Instagram and YouTube. Short-form dominates discovery, so for most local brands the bulk of your content should be on the shorter end, optimised for the feed and for sound-off viewing. Keep longer-form for your website, YouTube channel and situations where viewers have actively chosen to learn more — like an explainer they clicked on purpose. The strongest strategy pairs both: short clips to attract, longer videos to convince.
Frequently asked questions
What’s the ideal length for a social media video?
For most feed and short-form placements like TikTok and Reels, roughly 15–30 seconds works well, with a strong hook in the first second. Longer formats can perform once you’ve built a trusting audience, but shorter is the safer default for reach.
Can a marketing video be too long?
It can feel too long if it drags, but length itself isn’t the problem — engagement is. A compelling longer video beats a boring short one. The rule is to be as long as the content genuinely needs and not a second more.
Should ads be shorter than organic videos?
Usually, yes. For paid social, shorter cuts in the 15–30 second range tend to perform best, with the brand and key message front-loaded in case viewers scroll past. You’re paying for attention, so make every second count.
Do I need different lengths for different platforms?
Ideally, yes. The smart approach is to film once and edit multiple versions — a longer hero cut for your website or YouTube and several short clips for TikTok, Reels and ads — so one shoot covers every placement.
