How Long Should a Business Video Be?

By Caz, Project Team Lead  ·  4 min read

"How long should our video be?" is one of the most common questions in any video production brief — and one of the easiest to answer badly. The honest answer is: it depends. But there are clear patterns for every type of business video, and understanding them will help you brief better, spend smarter, and get more out of every piece of content you commission.

50%

viewer retention rate is achieved by videos lasting 90 seconds or less — making this the proven optimal range for most business video content.

Ideal Video Length by Format

Homepage and Brand Videos — 60 to 90 Seconds

A homepage video has one job: convert a visitor into an enquiry. You have a few seconds to hook someone who is already interested but not yet committed. Sixty to ninety seconds gives you enough time to establish what you do, why it matters, and what to do next — without testing patience. Beyond two minutes on a homepage, completion rates fall sharply.

Explainer Videos — 60 to 90 Seconds

The sweet spot for explainer videos is 60–90 seconds. This is long enough to cover a product or service clearly, and short enough to maintain attention. If your content genuinely cannot fit into 90 seconds, consider breaking it into a short teaser and a longer follow-up piece rather than stretching a single video past the point of engagement.

Social Media Videos — 15 to 60 Seconds

Social media is a scrolling environment. You are competing with an enormous amount of content for a fraction of a second of attention. The first three seconds determine whether someone keeps watching. For most social platforms, 15–60 seconds is optimal — though LinkedIn B2B content can sustain up to 90 seconds if it opens with a strong hook.

Video Advertisements — 15 to 30 Seconds

For paid video ads — pre-roll, social feed, display — 15 to 30 seconds is the target. Skippable YouTube ads need to deliver the key message within the first five seconds in case the viewer skips. Non-skippable ads are usually capped at 15 seconds by the platform. For social feed ads, 15–20 seconds drives the best completion and conversion rates.

Testimonials and Case Studies — 60 Seconds to 3 Minutes

Testimonial and case study videos have more latitude because the viewer is already interested — they are in research mode, evaluating their options. A well-structured case study can sustain up to two or three minutes. But even here, discipline pays off: the tightest, most specific testimonials are almost always the most persuasive.

Training and Educational Content — As Long as It Needs to Be

Training videos follow different rules. Five to ten minutes is common, though breaking long content into shorter chapters improves engagement and completion rates.

The Overriding Rule: As Short as Possible

Whatever format you are producing, the guiding principle is the same: make the video exactly as long as it needs to be, and not a second longer. The most common mistake in business video production is padding — adding context that doesn't serve the viewer, or saying in two minutes what could be said in forty-five seconds.

If you are unsure how long your video should be, start by writing the script. The right length will usually become clear. Read our guide on how to write a great video script for a step-by-step walkthrough.
