Speaking Time Calculator โ Words Per Minute, Script Length, and Delivery Guide
Speaking time = word count รท speaking speed (WPM). The average conversational speaking rate is 130โ150 words per minute. TED Talks are deliberately paced at about 130 WPM to give ideas room to land. Audiobooks run at 150โ160 WPM, and rapid presentations can reach 180โ200 WPM. Knowing your script's speaking time before rehearsal helps you calibrate content volume and avoid running over time.
Speaking speed by context:
Slow / deliberate: 100 WPM / TED Talk: 130 WPM
Standard presentation: 150 WPM / Fast delivery: 180 WPM / Rapid debate: 200+ WPM
Script word count by speech length (at 150 WPM):
1 min: 150 words / 3 min: 450 words / 5 min: 750 words
10 min: 1,500 words / 20 min: 3,000 words / 30 min: 4,500 words
Under pressure, most speakers naturally slow down โ aim to script at 80โ90% of your target time. Factor in pauses for emphasis, slide transitions, and audience reaction. A useful rule of thumb: multiply your calculated speaking time by 1.1 for in-person talks to account for natural pacing variation.
Frequently Asked Questions
A: For professional settings, 140โ160 WPM is appropriate โ fast enough to seem confident, slow enough to be clearly understood. Avoid speaking above 160 WPM in formal contexts; it signals nerves and makes complex content harder to follow. Slow down deliberately when introducing key data points or conclusions.
A: Wedding speeches typically run 3โ5 minutes (450โ750 words at 150 WPM). Anything over 7 minutes risks losing the audience's attention. Aim for 500โ600 words for a polished, well-received speech that covers key moments without overstaying the welcome.
A: Almost always. Live delivery is typically 10โ20% longer than rehearsal due to pauses, audience interaction, and nerves slowing you down. If your rehearsal runs exactly on time, you'll likely run over. Script to about 85% of the allotted time for a comfortable buffer.
