How long should a founder's short-form video be?

For most founder videos, 30 to 90 seconds is the sweet spot: long enough to make one clear point, short enough that people finish. The platforms now allow short-form videos of up to three minutes, so length is your choice rather than a technical limit. The real rule is that a video should be exactly as long as its single idea needs, and not a second longer.

What the limits are now

• YouTube Shorts: YouTube says square or vertical videos up to three minutes long are categorized as Shorts, for uploads from October 15, 2024.
• Instagram Reels: Instagram says reels must be three minutes or less to be recommended to people who don’t already follow you.
• LinkedIn and TikTok: both allow much longer videos, but short clips are still the norm in the feed.

What marketers say works

In Wyzowl’s 2026 survey, 71% of video marketers said videos between 30 seconds and 2 minutes work best. That’s a wide range, and it matches what we see with founder content: a single tight point lands in 30 to 60 seconds, a short story or explainer in 60 to 90, and a mini-tutorial can earn two minutes.

Length by format

These are starting points, not rules. If your explainer is clear at 40 seconds, stop at 40.

Why shorter usually wins

Attention drops from the very first second. Meta has reported that 65% of people who watched the first three seconds of a video kept watching for at least ten, and 45% for thirty. Every extra second has to earn its place.

Finishing matters to the platforms too. When Instagram’s Adam Mosseri explained how reels are ranked, whether someone will watch a reel all the way through was one of the main things he said the platform predicts. A tight 40-second video is far easier to finish than a loose two-minute one.

How to cut a video down

1. Cut the introduction. Start with the hook. Your name is already on the profile.
2. Cut the second example. One good example is enough.
3. Cut the recap. If you said it clearly once, don’t summarize it.
4. Cut the pauses. Tighten the gaps between sentences in the edit.
5. End on the point. Finish on the takeaway, not on “so yeah, that’s it.”

A good hook makes everything after it easier to keep tight: see how to write a hook for a founder video. Bullet-point prompts also stop you rambling: see whether founders should script their videos.

Keeping videos tight every week

The edit is where length is won or lost, and it’s the step founders skip when they’re busy. The DIY approach: a phone editing app, a rule that every video loses its first and last five seconds, and a second look the next morning before posting.

Dopameme handles this edit for founders, cutting each recording down to the version that holds attention and keeping every video to one idea. Whoever edits, the rule doesn’t change: one idea, no padding.

Bottom line

Aim for 30 to 90 seconds for most founder videos, and go up to two or three minutes only when the idea genuinely needs it. YouTube Shorts and Instagram Reels both allow up to three minutes, and most marketers say 30 seconds to 2 minutes works best. Cut the intro, the extra example and the recap, and end on the point.
