How to use it
Using the speaking time calculator
- 01
Count the script
Run your draft through the word counter for an exact figure.
- 02
Set your pace
Time yourself reading one paragraph aloud and compute your true wpm.
- 03
Trim to the slot
Cut until the estimate sits under your time limit with buffer for pauses.
Good to know
Speaking is not reading
Listeners cannot rewind. Effective speakers deliver 120–140 wpm versus the 238 wpm people read silently; less than half the throughput. A script sized for a reading session will blow a speaking slot by nearly double.
The rehearsal correction
Paper estimates start the process; a stopwatch finishes it. Record yourself reading 200 words, note the seconds, and derive your personal wpm; nerves typically push first-timers 10–15% faster than practice.
Budgeting real events
A 20-minute conference slot is really 17 minutes after walking on stage and switching slides. Aim your word count at the reduced window, leaving silence available for laughs and emphasis instead of racing the clock.
How it's calculated
The math behind this calculator
Duration = word count ÷ speaking pace (wpm)Spoken delivery runs slower than reading: presentations land near 130 words per minute against 238 for silent reading, because pauses, emphasis and audience reactions all take real seconds. Divide words by your pace to get minutes, then humanize the result into hours, minutes and seconds.
Assumptions & limitations
- Default pace of 130 wpm fits conversational presentations.
- Fast broadcasters approach 160–170 wpm; solemn readings drop below 110.
- Slides, applause and Q&A time are not included.
Worked example
A 2,000-word conference talk runs about fifteen and a half minutes at a typical 130 wpm delivery.
FAQ
Frequently asked questions
- How many words is a 5-minute speech?
- At the default 130 wpm, about 650 words. Nervous-fast speakers might need 800; deliberate keynote pacing closer to 550.
- Should pauses count?
- Indirectly yes; the 130 wpm default already assumes natural pausing. Add extra time manually only for planned silences like slide transitions or dramatic beats.
- Does accent or language change pace?
- Syllable rate varies more than word rate: Spanish and Japanese pack more syllables per second, so calibrate within the actual language you will speak.
- How accurate is this for voiceover work?
- Professional narration runs 150–160 wpm with clean diction; set the pace accordingly and expect commercial reads to run longer with direction stops.
