The honest answer is "as long as it needs to be and not a second longer" — but that's not useful when you're staring at a timeline. Here's a practical framework.
The sweet spot: 30–60 seconds
For vertical feeds — Shorts, Reels, TikTok — most clips that perform sit between 30 and 60 seconds. That's enough room for a hook in the first two seconds, one complete idea, and a payoff, without asking a scrolling viewer for a bigger commitment than they'll give a stranger.
When to go to 90 seconds
- The payoff genuinely needs the build-up — a story with a turn, a step-by-step explanation.
- Two speakers are going back and forth and cutting it shorter would lose the exchange.
- The content is strong enough that people will stay — a well-known guest, a genuinely surprising claim.
Past 90 seconds you're really posting a mini-episode, which is a different thing with different expectations.
When to go shorter — 15–25 seconds
A single punchy line, a one-sentence hot take, a quotable definition. If the whole value is one sentence, don't pad it to 45 seconds.
The real constraint isn't time, it's the hook-to-payoff ratio. If the first 10 seconds don't earn the next 30, no length will save the clip.
Trim to the moment, not the clock
Start by finding the complete thought (see how to clip a podcast episode), then tighten: move the start to the first strong sentence, cut dead air, end on the payoff. Whatever length that leaves you with is usually right. Cuts that land on natural silence, not mid-word, matter more than hitting a target duration.
How ClipSonic handles length
ClipSonic's highlight detection targets self-contained moments in the 20–90 second range and snaps the in/out points to silence, and you can retrim any suggestion. There's also a fixed-length mode if you want every clip cut to exactly 30, 45 or 60 seconds. More on the workflow: the AI podcast clipper and adding captions to podcast clips.
