Speech length calculator

Turn words into a spoken length

The speech length calculator estimates how long a draft takes to say, or how many words fit a slot, at a pace you set. Paste a script, or press Enter a word count instead and type a number. The pace slider runs from 90 to 180 words per minute and starts at 130. The speech length calculator then shows a clock for that word count and a table for 1, 3, 5, 10, 15, and 20 minutes at the same pace.

At the default 130, the table's five-minute row is about 650 words. At 110 it is about 550. At 150 it is about 750. The speech length calculator recomputes the table when you move the slider, even if the script box is empty. The clock follows the script or the typed count, whichever mode you are in. Empty script mode shows 0:00 and 0 words. The table still shows the slot budgets.

Press Paste a script instead to return from the number field. The speech length calculator does not try to remember a half-written script across that toggle in a clever way: the script text stays in the box, and the count field stays at its number. The mode decides which one drives the clock.

The arithmetic, with no extra buffer

Seconds = words ÷ words per minute × 60. Words for a slot = minutes × words per minute, rounded. The speech length calculator does not add a hidden pause percentage. If you need 10 percent for laughter or a demo, shorten the word budget yourself. A five-minute slot you will interrupt is not a 650-word script at 130. Write fewer words, or set the pace slider to the rate you measured with pauses included.

A word matches letters and digits, apostrophes inside contractions included. The speech length calculator counts "don't" as one word. It counts a pasted heading you will not say. Delete labels, citations, and slide numbers before you trust the clock.

90 words per minute on the slider is a slow ceremonial pace. 180 is a fast narration. The speech length calculator will accept both. Neither is a recommendation for every room. 130 is the start because it is a common conversational planning rate, not because every speaker owes the room that number.

Worked budgets

One minute at 130 is 130 words. Three minutes is 390. Five is 650. Ten is 1,300. Fifteen is 1,950. Twenty is 2,600. The speech length calculator rounds from the slider, so a pace of 125 will not match those round 130 figures. Read the table on the page after you move the slider. Do not memorize the 130 column and ignore the control.

A 90-second toast is 1.5 × 130 = 195 words at the default. The speech length calculator's shortest table row is one minute, so use the clock for 195 words rather than forcing the toast into the one-minute row. Type 195 in word-count mode. The clock should read about 1:30.

A 10-minute briefing at 110 words per minute is about 1,100 words. At 150 it is about 1,500. The speech length calculator makes that spread obvious so you do not copy a word target from a blog that assumed a different pace. If your measured rate is 142, set the slider there and use that row. The published "650 words for five minutes" line is only true near 130.

An elevator pitch near 30 seconds is about 65 to 70 words at 130. The speech length calculator will show roughly 0:30 for 65 words. The pitch builder's own note of 70 to 90 words is the same neighborhood and runs longer if you keep every prompt. Check the keeper in this speech length calculator before you memorize it.

Script mode versus a bare count

Use script mode when the sentences exist. The speech length calculator is then counting your draft, not a dream word count. Use count mode when you are still deciding the slot and you do not have prose. A number with no sentences cannot tell you that a paragraph is unspeakable. It can only tell you the budget.

If script mode and your editor disagree by a few words, trust a quick read of what the speech length calculator highlighted by count, then check contractions and hyphenated forms. Do not spend ten minutes reconciling tools. The live read will move the result more than a two-word argument.

Switching modes does not upload anything. The speech length calculator stays in the tab. Refresh clears both the script and returns the controls to their defaults.

Where the estimate misleads

The speech length calculator assumes you keep talking at one pace. It misses planned pauses, a walk to a demo, laughter, and questions. A keynote with two pauses of 1.5 seconds is trivially close. A talk that stops for a three-minute exercise is not a speech length calculator problem. Subtract the exercise from the slot, then size the spoken part.

Reading the draft silently and calling that the length will make you late. The silent-reading figure lives on the speech timer, at 238 words per minute, for exactly this warning. The speech length calculator is the spoken estimate. Use it as spoken.

A memorized script often runs faster than a first read, until a blank hits and it runs slower. The speech length calculator cannot see that. After you have a number, say the draft once against a clock. If you were 20 seconds under, you have room. If you were 20 seconds over, cut. Do not average the calculator and your hope.

Very short texts are noisy. A 12-word opener at 130 is about 6 seconds. The speech length calculator will say so. Do not treat a six-second estimate as a precision instrument for comedy timing.

Pair it with a real read

When the speech length calculator says the budget fits, stop collecting word counts. Move to the speech timer if you want the long-or-short sentence against a specific target, or stand up and speak. When it says the draft is heavy, cut a section and paste again. Changing the slider to 170 to "make it fit" is how you plan a rush.

The readability checker is the next stop if the words fit the clock but the sentences are written for the page. A 650-word script of 40-word sentences will not survive 130 words per minute just because the speech length calculator approved the count.

For a toast, a pitch, or an outline, draft there, then return to the speech length calculator with the words you will actually say. Placeholders in brackets still count. Fill them or delete them before the final clock.

Budgets at 130, and why your editor disagrees

The speech length calculator turns words into minutes at the pace on the slider, which runs from 90 to 180 and starts at 130. It does not add a hidden pause buffer. If you want air, reserve it yourself by aiming short. At 130 words per minute the table slots are about 130, 390, 650, 1300, 1950, and 2600 words for one, three, five, ten, fifteen, and twenty minutes. Five minutes is the 650-word row. At 110, five minutes is nearer 550 words. At 150, nearer 750. The speech length calculator rounds the word budgets to whole words.

Paste the spoken draft, or switch to a word count when you do not have the text. A word is letters and digits, with apostrophes inside contractions, so "don't" is one word. The speech length calculator will also count a heading you do not plan to say. Delete labels before you trust the clock. A document that counts differently is using a different word rule. Believe this page for the estimate you will speak, and cut the labels.

The speech length calculator does not upload the script and does not know your pauses. Pair it with one aloud read. If the read runs long, cut words and check again. Do not add a percentage "for pauses" on top of a formula that already refused to invent one.
