📖What is it?

Speaking pace varies by style and context. TED Talks are delivered at approx 150 WPM -- fast enough to maintain energy, slow enough for comprehension. Podcast hosts average 140-160 WPM in natural conversation. This calculator converts word count to delivery time with a configurable pause buffer.

🎯How to use

Enter your script word count, select your speaking pace, and add a pause percentage (15% is typical for presentations with slide transitions and emphasis pauses). The output shows total time with and without the pause buffer.

💡Example scenario

A 1,500-word conference talk at 150 WPM runs exactly 10 minutes in pure speech. With 15% pause buffer = 11.5 minutes -- comfortably within a 15-minute slot. A 7,500-word keynote at 130 WPM + 20% buffer = 69.2 minutes (approx 1 hour 9 minutes).

🏆Pro tip

Industry slide rules: 1 slide per 2-3 minutes (detailed technical), 1 slide per 1 minute (fast-paced pitch). For a strict 10-minute slot at 150 WPM, allow approx 1,300 words of scripted content after reserving 15% for pauses. Record a rehearsal to calibrate your actual pace -- most speakers are faster under pressure.
