Speaking Time Calculator

How to use the speaking time calculator

1. Paste your script, or enter a word count — or switch to Time → words and set the slot you have to fill.
2. Pick a speaking speed, or measure your own with the built-in test.
3. Add a pause allowance if the talk has slides or questions, and read the result at all three speeds.

What a speaking time calculator does

A speaking time calculator estimates how long spoken content will take, from the number of words and the speaker's rate in words per minute. The formula is simply word count divided by rate — 1,400 words at 140 words per minute is 10 minutes.

It runs both ways here. Paste a script to find how long it takes to deliver, or set a target duration to find how many words will fill it, which is the more common problem when the slot is fixed and the script is not.

Because the rate carries the whole estimate, it is a control rather than an assumption: three presets, a slider for any rate between 70 and 220, and a test that measures your own speaking speed by timing you reading a passage aloud.

How long will my speech take?

Speaking time is the word count divided by your speaking rate: 1,400 words at 140 words per minute is ten minutes. The division is the easy part, and the rate is where the estimate actually lives — the same script can run three minutes longer or shorter depending on who delivers it.

The table below gives each word count at all three preset speeds, so a script can be checked against a time limit without guessing which rate applies.

Speech word count by duration

Working the other way — from a time slot to a script length — is the more common problem, because the slot is usually fixed and the script is not.

How many words for a 5-minute speech?

At an average speaking pace of 140 words per minute, a five-minute speech is about 700 words. Delivered slowly it is closer to 550, and at a fast conversational pace nearer 850.

Write to the slower end of that range. A five-minute slot with 850 words of script leaves no room for a pause, a question or a slide that will not advance, and running over is far more noticeable to an audience than finishing early.

How many words for a 10-minute presentation?

About 1,400 words at an average pace — roughly 1,100 if you speak deliberately, and up to 1,700 at pace. For a presentation with slides, the lower figure is the safer target, because every slide transition costs a few seconds that the word count does not see.

Longer formats scale the same way: a 20-minute talk is around 2,800 words and a 45-minute conference session around 6,300, which is why almost nobody speaks from a full script at that length.

Words to minutes

To convert a word count into minutes, divide by the speaking rate. These are the counts people most often arrive with, at an average pace:

• 500 words is about 3m 34s.
• 750 words is about 5m 21s.
• 1,000 words is about 7m 09s.
• 1,500 words is about 10m 43s.
• 2,000 words is about 14m 17s.
• 3,000 words is about 21m 26s.

Typical speaking speeds

The three presets are a slow, average and fast spread rather than a claim about any one speaker. Real rates depend on the material and the room, and these are the ranges worth aiming at:

Accounting for pauses

A word count cannot see silence, and silence is a large part of a good talk. Slide changes, a beat before a key sentence, laughter, a question from the floor and the moment you lose your place all add time that no calculation predicts.

The pause allowance adds a percentage to the result for exactly this. Ten per cent is a reasonable default for a rehearsed talk with slides — it turns a 7m 09s script into 7m 51s — and fifteen to twenty is more realistic for anything with audience interaction.

If the slot is hard, rehearse aloud with a timer rather than trusting any figure on this page. Nerves make most speakers faster than they rehearse, which is the one direction the arithmetic cannot warn you about.

Is speaking time the same as reading time?

No, and the gap is large. Silent reading runs at roughly 200 to 260 words per minute for an adult reading ordinary prose — comfortably faster than anyone speaks. A script that takes four minutes to read takes about seven to say aloud.

That difference is why a talk timed by reading it silently almost always overruns, and why rehearsing in your head is not rehearsing.

Common uses

• Checking whether a conference talk fits its slot before the rehearsal.
• Working out how many words a five- or ten-minute speech needs.
• Timing a podcast or video script before recording it.
• Keeping a school or business presentation inside its time limit.

Frequently asked questions

How long does it take to speak 1,000 words?

About 7m 09s at an average pace of 140 words per minute. Slowly it is nearer 9m 05s, and at a fast conversational pace about 5m 53s.

How many words are in a 5-minute speech?

Roughly 700 words at an average pace, or between 550 and 850 depending on delivery. Aim at the lower end if the five minutes is a hard limit.

How many words are in a 10-minute speech?

About 1,400 words at 140 words per minute, and around 1,100 if you speak deliberately. Subtract a little more for every slide you plan to change.

How many words should a 15-minute presentation be?

Around 2,100 words of script at an average pace. Most 15-minute presentations are not fully scripted, so it is more useful as a ceiling than a target.

What is a normal speaking speed in words per minute?

Conversational English runs at about 140 to 160 words per minute, and prepared presentations at 130 to 150. Formal delivery is slower than most people expect, which is why rehearsing at a comfortable pace and delivering faster is such a common way to finish early.

Is speaking time the same as reading time?

No. Silent reading is roughly 200 to 260 words per minute, well above any speaking pace, so a script read silently takes far less time than the same script delivered aloud. Timing a talk by reading it in your head will always underestimate it.

How do I calculate speaking time?

Divide the word count by your speaking rate in words per minute. 1,400 words at 140 words per minute is 10 minutes. Add 10 to 15 per cent if the talk has slides, questions or anywhere you intend to pause.

Does pausing affect speaking time?

Considerably. Slide changes, emphasis, laughter and questions are invisible to a word count and can add a fifth to the running time of an interactive talk. The pause allowance here adds a percentage so the estimate reflects that.

Can I use a custom words-per-minute rate?

Yes — the slider takes any rate from 70 to 220, and there is a built-in test that measures your own. Read the sample passage aloud, stop the timer, and the tool works out your rate from the words you read and the time you took.

Can I paste an entire speech or script?

Yes. Paste the text and the words are counted for you; there is no length limit, and a word count can be typed instead if you have one already.

Why did my rehearsal take longer than the estimate?

Almost always pauses, and occasionally a section you delivered more slowly than you wrote it. The calculation covers words only, so raise the pause allowance until the estimate matches your timed run-through, then use that figure for the next draft.

Is my text uploaded or stored?

No. The word count and the arithmetic run in your browser, nothing is sent to a server, and nothing is kept when you leave the page. The speaking-speed test times you rather than listening — no microphone is used or requested.
