How Long Should a Product Launch Video Be? Length by Channel and Goal
Most product launch videos should run 20 to 60 seconds. Here is the right length for each channel, how to calculate yours from your script, and when longer is worth it.
September 2026
The honest answer is: as short as your message allows, and almost always shorter than your first draft. For most products that means 20 to 60 seconds, with 25 to 45 seconds as the range most launch videos should aim for. But the right length depends on where the video will be watched and what it has to do there.
Platform limits won't help you decide. Every major platform allows videos far longer than any launch video should be. Attention sets the length, not the upload form.
Recommended length by channel
| Where it plays | Recommended length | Why |
|---|---|---|
| Social feed teaser (X, LinkedIn) | 15 to 30 seconds | Viewers are scrolling. One hook, one visual, one call to action. |
| Launch post or Product Hunt gallery | 30 to 60 seconds | Viewers chose to look. Room for the problem, the product working, and proof. |
| Landing page hero | 30 to 90 seconds | Visitors are evaluating. The full story, often on loop or on click. |
| Demo video | 60 to 120 seconds | Proving one workflow end to end takes longer than announcing. |
| Walkthrough | 30 to 90 seconds per task | One task each; longer topics become a series. |
Calculate your length from your script
Instead of choosing a number and filling it, build the video from beats and let the total fall out. A beat is one moment with one job, and most beats need 3 to 5 seconds:
| Beat | Typical length |
|---|---|
| Hook: the problem | 3 to 5 seconds |
| Reveal: the name or definition | 2 to 4 seconds |
| Show: the product working (one or more) | 4 to 8 seconds each |
| Proof: one number | 3 to 4 seconds |
| Close: one call to action | 3 to 5 seconds |
Five or six beats at those lengths lands between 20 and 35 seconds. That is why so many good launch videos cluster around 25 seconds: it is simply what five or six well-sized ideas add up to.
Let the text set the minimum
Each beat has to stay on screen long enough for its text to be read. A reliable rule is about 15 characters per second, so a 45-character line needs 3 seconds and a 75-character line needs 5. If a beat's text needs more time than the beat has, the fix is almost always a shorter line, not a longer video.
Three real examples
Demogent's three launch templates show how length follows content. The SaaS launch for Relay runs 23 seconds across six beats. The AI product explainer for Kestrel runs 26.5 seconds, because an AI product needs an extra beat to say plainly what it does. The developer tool launch for Forge runs 29 seconds, the longest of the three, because eight of those seconds are a terminal running the product, and output needs time to be read. We break down all three in product launch video examples.
When longer is worth it
Extra seconds earn their place when they show the product doing something, and waste them when they add claims about it. Forge's eight-second terminal beat is justified because the output is the explanation. A second feature list, a team slide, or a longer logo animation is not.
- Worth the time: the product working, a real result appearing, a number with its mechanism explained.
- Not worth the time: additional features, testimonials read aloud, long intros, logo animations over two seconds, and repeating the call to action.
Make one video, cut three lengths
You don't have to choose a single length. Build the full 30 to 45 second version first, then cut it down: keep the hook, the most visual show beat, and the close for a 15-second social teaser. The long version goes on your landing page and in the launch post; the short one goes in feeds.
Demogent timelines run up to 60 seconds and clips snap to half seconds, so cutting a shorter version from a finished project is a matter of removing beats and letting the rest reflow. For the full process, read how to make a product launch video.

Frequently asked questions
What is the ideal length for a product launch video?
25 to 45 seconds for most products. Anything from 20 to 60 seconds can work if every beat earns its time.
Is 60 seconds too long for a launch video?
Not if the video shows the product working throughout. It is too long if the extra time goes to feature lists, intros, or repeated claims.
How long should a video be for social media?
15 to 30 seconds for a feed teaser. Cut it from your full launch video by keeping the hook, the most visual scene, and the close.
How long should a SaaS demo video be?
Around 60 seconds for a landing page demo. See our SaaS demo video guide for a second-by-second shot list.
