How Long Should a Business Video Be?

Short answer

Short-form social (TikTok, Reels, YouTube Shorts): 15–60 seconds. YouTube long-form: 7–15 minutes for most business topics. Website homepage or product explainer: 60–90 seconds. Always lead with the value — cut anything that doesn't serve the viewer.

Ideal video lengths by platform

Platform	Best length	Why
TikTok	15–60 seconds	Algorithm favours high completion rate; shorter = higher completion
Instagram Reels	15–30 seconds	Sweet spot for reach; Reels over 60s lose reach
YouTube Shorts	Under 60 seconds	Must be under 60s to qualify as a Short
YouTube (long-form)	7–15 minutes	Long enough to be substantive; sweet spot for watch time
Website homepage	60–90 seconds	Visitor attention span; decision-making context
Website product demo	2–3 minutes	Enough to explain features and build confidence
Email video	Under 2 minutes	Most email readers won't commit to longer

The real rule: length should match content

The actual rule isn't "keep it under X minutes" — it's don't pad, and don't cut too early.

If you genuinely need 12 minutes to cover the topic thoroughly, a 12-minute video will outperform a rushed 5-minute version. But if you're filling 12 minutes when 5 would do, viewers will leave at minute 5 and tank your ranking.

Watch time (what percentage of the video viewers watch) matters more to YouTube's algorithm than the total length of the video.

How to find the right length for your content

Script it out first. If the script runs long, cut sections — not seconds. Don't speed up your delivery. A video that feels rushed is worse than a longer one that feels natural.

After posting, check your YouTube Analytics "Audience retention" graph. The point where viewers start dropping off is where you're losing them — trim or restructure that section in future videos.
