The math
Most people speak at about 2.5 words per second in a clear, energetic short-form delivery.
- 30 seconds: about 70–80 words
- 45 seconds: about 105–115 words
- 60 seconds: about 140–150 words
Leave room for pauses, on-screen moments with no talking, and your CTA.
Budget by part
For a 45-second video:
- Hook: 0–3 s (about 8 words)
- Tension: 3–15 s (about 30 words)
- Payoff: 15–40 s (about 60 words)
- CTA: 40–45 s (about 12 words)
Trimming
If you're over:
- Cut the tension first. People often over-explain the problem.
- Replace spoken words with visuals (lesson 5).
- Make it two videos. A long payoff with several steps might be a series.
Shorter usually wins. A tight 30 seconds that people finish beats a baggy 60 that they don't.
Try it
Count your words, pick your target length, and trim to fit. Mark each part (hook, tension, payoff, CTA) with its timing, which you'll reuse in the storyboard.
