The Ideal Length for TikToks, Reels & Shorts (and Why)
Shorter isn't always better — and longer isn't always worse. Here's how to think about video length in a way that actually maximizes reach.
"How long should my video be?" has a frustrating-but-true answer: exactly as long as it stays interesting, and not a second more. But there are useful patterns underneath that, so let's get specific.
What the platforms actually reward
All three platforms optimize for watch time and completion rate, not raw length. A short clip that's fully watched and rewatched sends a stronger signal than a long one people bail on. So length is a means, not the goal — the goal is holding attention end to end.
Sensible ranges
- ▸Quick hooks, punchlines, hot takes: 7–15 seconds — high completion, very shareable.
- ▸Tips, stories, mini-explainers: 20–40 seconds — long enough to deliver value.
- ▸Deeper storytelling: 45–60s+ — only if every second earns its place.
If your retention graph flatlines near the end, your video is the right length. If it nosedives partway, you're too long — cut to where the energy drops.
