Promotional Video Length: How Long It Should Be

November 2, 2026 11 Min Read

Most promotional videos work best between 15 seconds and 3 minutes. Where you land in that range depends on where the video will play and what you want the viewer to do next. For awareness on social media, aim for 15 to 60 seconds. For a homepage or landing page explainer, 60 to 90 seconds is a sensible target. Move toward 2 or 3 minutes only when the story needs it and the viewer already has a reason to stay.

This guide gives you the ranges, the platform limits that are fixed by the platforms themselves, and a way to decide for your own video. It also shows how to cut a video to length once you know the target.

Purpose should pick the length: short for awareness, medium for explanation, longer only for audiences ready to learn or buy.
Shorter is not always better. In one Google study, the 15-second cut drove recall, while longer cuts lifted brand favorability.
Plan one master edit, then trim versions for each placement instead of making one video fit everywhere.

The short answer: length by goal

The most useful way to choose a length is to start with the job the video has to do. A video that introduces your business to strangers has a different job from one that walks a warm lead through a product.

One Wistia guide defines a promotional video as one that usually runs 30 seconds to 3 minutes, built to create interest and prompt an action. Another channel guide from Vidyard puts the general promotional range at 15 to 60 seconds, following the familiar digital ad and TV spot format that most B2B companies adopt. The two ranges overlap, and the gap between them is explained by placement: the shorter figure assumes paid or feed placement, and the longer one assumes the viewer chose to press play.

Wistia’s length guidance by goal lines up like this:

Goal	Suggested length	Typical use
Brand awareness, social engagement	Under 1 minute	Teasers, ads, feed clips
Education and explanation	1 to 5 minutes	Product explainers, how-it-works videos
Conversion or nurturing	5 to 30 minutes	Demos, webinars, longer case studies
Retention or training	30 minutes or more	Onboarding, courses

A promotional video sits mostly in the first two rows. If your video runs past five minutes, it has probably stopped being a promo and become a demo or a training piece, which is fine, but it should be planned that way.

What the engagement data says

Wistia’s 2026 State of Video Report data, summarized in its length guide, says videos under one minute average 52% engagement. Customer testimonials come in at 46% and product videos at 50%. Those figures come from viewing on Wistia-hosted videos, so treat them as a benchmark for comparison, not a promise for your channel. What they do show is the pattern most marketers see: the shorter the video, the higher the share of it people watch.

Length by platform

Social platforms add a second layer. Each has a ceiling, and each audience behaves differently. Hootsuite’s June 2026 guide says most social videos fall between 15 and 60 seconds, with the exact figure depending on the platform and format. The same guide gives these recommendations for the two channels most promotional teams ask about:

Placement	Recommended length
LinkedIn organic video	30 to 60 seconds
LinkedIn video ads	15 to 30 seconds
YouTube bumper ads	6 seconds or less
YouTube non-skippable in-stream ads	7 to 15 seconds
YouTube skippable in-stream ads	12 seconds to 3 minutes, with 30 to 60 seconds as the sweet spot

So is a 3-minute video too long for LinkedIn? For a paid ad, yes. For a product story you post to people who already follow your company, it can work if the first few seconds carry the point and the captions make it watchable on mute. For cold reach, stay at 30 to 60 seconds.

How long is a short video?

The question of how many minutes a short video should be has a changing answer. YouTube Help states that square or vertical videos uploaded on or after October 15, 2024 can qualify as YouTube Shorts at up to 3 minutes, subject to its eligibility rules. YouTube’s creator guidance adds that Shorts are capped at 3 minutes, should capture attention in the first few seconds, and are optimized for vertical 9:16 viewing.

That 3-minute ceiling is a ceiling, not a target. For a promo on Shorts, Reels or TikTok, 15 to 30 seconds is a safer plan. If you are formatting for these feeds, our guide to adapting edits for short and vertical formats covers framing, and what formats engage best on TikTok, Instagram and YouTube shows how the three differ. For exact dimensions, see social media video sizes for every platform.

Length by ad format

When you pay for placement, the format often decides for you. Google Ads’ help page on non-skippable in-stream ads states that these ads support bumper videos up to 6 seconds and standard non-skippable videos of 7 to 15 seconds. On connected TV, non-skippable ads can run 16 to 30 seconds.

Skippable ads are more flexible. Google’s reservation guidance says skippable in-stream ads have no length limit, but videos under 3 minutes typically perform better. The same page lists Shorts reservation ads at 6 to 60 seconds and bumper ads at 6 seconds.

The practical logic is straightforward:

Non-skippable ads must deliver the message in a short, fixed window. Write for the window: one idea, the brand on screen early, one clear next step.
Skippable ads reward a strong opening. The viewer decides in the first moments, so the hook matters more than the total running time.
Bumpers are for recognition, not explanation. Think one image, one line, one logo.

What should decide your length

A range is a starting point. Four factors move your video up or down inside it.

Audience and screen

The IAB’s Multiscreen Video Best Practices report tested 10- and 30-second ads across desktop, smartphone and tablet. It found that 10-second ads can maximize impact among Millennials, while 30-second ads can have an advantage on lower-funnel metrics among consumers aged 35 to 54. The report is from 2016, so use it for the principle, not the exact figures: the right length depends on who is watching and on what screen, not simply on making the video as short as possible. Hospitality businesses weighing these trade-offs can read about marketing for short-term rental operators, where the same questions of audience and campaign goal shape what gets produced.

Message complexity

A flash sale fits in 10 seconds. A service with three steps and a price comparison needs 60 to 90 seconds. If you cannot state the offer in one sentence, shorten the message before you shorten the video.

Funnel stage

People who have never heard of you need a brief, memorable introduction. People who have visited your pricing page will sit through a longer walk-through. Match the length to how much the viewer already knows.

Brand familiarity

Unknown brands have a particular problem: they need enough time to be understood. One of the pages ranking for this topic suggests a video ad for a new business should be at least 15 seconds to drive measurable action. We would treat that as a reasonable rule of thumb, not a law.

When shorter is not better

It is tempting to read all of this as “cut everything to 15 seconds.” The evidence is more interesting than that. A Google study from September 2015 tested three lengths of a Honey Maid ad in the U.S. The 30-second version had a view-through rate 30% higher than the 15-second version. Yet the 15-second cut was the only one to drive significant ad recall across all three tested lengths. The study also found longer cuts lifted brand favorability.

The takeaway is that length trades one outcome for another. A short cut can be remembered more; a longer cut can make people like the brand more. If you are trying to persuade people with a more complex story, a longer cut earns its time. If you are trying to be recalled in a crowded feed, keep it tight.

For long-form, Wistia’s 2026 data in its length guide says videos of 5 to 30 minutes average a 9% click-through rate, while engagement drops 11% once a video exceeds 30 minutes. Longer videos can convert, but only for viewers who chose to watch them.

Our perspective

Most people fail at video length for a practical reason, not a creative one: they cannot easily make a second version. They finish one edit, post it everywhere, and accept whatever happens.

We built Kudoflix around the opposite habit. Because the editor runs in the browser, with nothing to install, you can open a finished project, duplicate it, and cut a 15-second teaser, a 30-second ad and a 60-second feed version in one sitting. The timeline, keyframes, text options and templates are all there, so each cut can be reframed and retitled rather than just chopped.

Our view is that the best promotional length is the one you tested. Plan a master edit that tells the whole story, then make the short versions on purpose. Put the hook and the offer first, keep the logo and call to action in every cut, and let the platform tell you which length your audience prefers.

That workflow should not need a powerful computer or a training course. We designed our cloud processing so that families, small shops, clubs and educators can do it on ordinary devices, and so that the second and third version cost minutes, not days.

Once you have a target, trimming is a process. Here is a workflow that works for most small-business promos.

Write the one-sentence message. If the video is for a bakery, it might be: “Fresh bread every morning, order by 9 p.m. for pickup.” Everything on screen should support that sentence.
Set a time budget per beat. For a 30-second video, a sample budget is 3 seconds for the hook, 15 for the product or service in use, 6 for proof such as a customer line or a result, and 6 for the offer and next step.
Cut the opening first. Remove logo animations and slow fades from the start. The brand can appear in the first few seconds without a long intro.
Trim each clip to its useful moment. Most footage has a second or two of settling at the start and end of each shot. Cutting these alone often saves 10 to 15% of running time.
Add captions. Many people watch feeds without sound, and captions let you shorten spoken narration.
Export a version for each placement. Keep 16:9 for your website and YouTube, and make 9:16 for Shorts, Reels and TikTok.

Common mistakes

One length for every platform. A 90-second brand film is a good website video and a poor bumper ad.
A slow start. Whatever the total length, the opening seconds decide whether the rest is seen.
Too many messages. Each extra point adds time and lowers the odds any single point sticks.
No next step. A promo exists to prompt an action, so end with one: visit, call, book, order.

FAQ

For most businesses, 30 to 60 seconds is the safe middle. Use 15 to 30 seconds for ads and feed posts, and up to 90 seconds for a homepage or landing page video. Stretch toward 3 minutes only when the story is complex and the viewer chose to watch.

How many minutes should a short video be?

On YouTube, Shorts can now be up to 3 minutes for qualifying square or vertical uploads. That is the maximum, not a recommendation. For a promotional short, 15 to 30 seconds usually holds attention best, so use extra time only if every second adds something.

Is a 3-minute video too long for LinkedIn?

For an ad, usually yes: Hootsuite recommends 15 to 30 seconds for LinkedIn ads and 30 to 60 seconds for organic video. For a story posted to existing followers, 3 minutes can work if the opening is strong and captions are on. Test it against a 60-second cut.

What is the best length for a YouTube ad?

It depends on the format. Bumper ads are 6 seconds, non-skippable in-stream ads run 7 to 15 seconds, and skippable ads can be longer, though Google says those under 3 minutes typically perform better. A 30 to 60 second skippable ad is a common starting point.

Should I make a different version for every platform?

Yes, if you can. The platforms use different shapes, caps and viewing habits, so one cut rarely fits all. Make a master edit first, then trim shorter versions and reframe them for vertical and horizontal screens.
