Speech Time Calculator
Convert a word count into speaking time — or a time slot into a word budget — for speeches, presentations and voice-overs.
Conversation runs 150–180 wpm, but good public speaking is deliberately slower — 120–150 wpm — because pauses, emphasis and audience reaction eat time. TED coaches target ~130 wpm. For voice-over and audiobooks, 150–160 wpm is standard. Always rehearse aloud with a timer: written sentences that look short can speak long, and nerves speed most people up by 10–20%.

About Speech Time Calculator
"How many words is a 5-minute speech?" — about 650 at presentation pace, and this calculator gives you the precise number both ways. In words-to-time mode it converts a drafted script into realistic speaking time at your chosen pace; in time-slot mode it converts the minutes you've been given into a word budget before you write a single line. The paces are the ones professionals actually use: 110 wpm for ceremonial delivery (toasts, eulogies), 130 wpm for presentations (the TED-coach target), 150 wpm conversational, 170 wpm for fast, energetic delivery. Speakers who draft to a word budget and rehearse with a timer are the ones who never get played off the stage.

Frequently asked questions
How many words is a 5-minute / 10-minute / 20-minute speech?+
At a 130-wpm presentation pace: 5 minutes ≈ 650 words, 10 minutes ≈ 1,300, 20 minutes ≈ 2,600. At conversational 150 wpm add about 15% to each. Draft roughly 10% under your slot — Q&A overruns, laughs and applause, a sip of water, and the pause before your key point all consume time the script doesn't show.
What's the ideal speaking pace for a presentation?+
120–150 wpm. Slower than conversation on purpose: a live audience can't rewind, so pauses do the work punctuation does in print. Famous baselines: most TED talks land near 130 wpm; audiobook narration standardizes around 150–160. Below 110 wpm feels labored; above 170, comprehension drops and you sound nervous even if you aren't.
Why does my speech run long even when the word count fits?+
Because scripts omit the non-verbal runtime: slide transitions, audience reaction, rhetorical pauses, and the deep breath before each section. Those typically add 10–20% to pure reading time. Nerves cut the other way — most people speed up under pressure — which is why the only trustworthy number is a full out-loud rehearsal with a timer, ideally standing.
How long should a best-man toast or wedding speech be?+
Two to four minutes — 220 to 520 words at the slow ceremonial pace of 110–130 wpm that suits toasts. Anything past five minutes loses the room, especially before dinner. Write three short beats (story, sincere line, raise the glass), time it aloud twice, and cut the weakest 20%: short and rehearsed beats long and improvised every time.
