How the speaking time calculator works

Speaking is much slower than reading. A silent reader manages around 240 words a minute; the same person reading aloud drops to roughly 150, and a speaker who wants to be understood by a room drops further still. That gap is why a script that looks short on the page runs long at the lectern, and why a five-minute lightning talk needs a surprisingly small number of words.

What the presets mean. Presentation at 130 wpm is the pace of a clear, deliberate talk with room for slides and audience reaction; most public-speaking coaches recommend somewhere between 120 and 150 for anything with an audience. Conversational at 150 is ordinary unscripted speech in English. Podcast at 160 reflects the slightly brisker pace of two people talking into microphones without an audience to pace themselves against. Voiceover and audiobook at 155 match the industry rule of thumb that a 60-second commercial script is about 150 to 160 words, and that an audiobook narrator covers about 9,300 words an hour. Radio news at 170 is the fastest professional pace that stays intelligible; Fast talker at 190 is for a rapid presenter or a first run-through you know you will slow down in performance.

Why sentence pauses matter. Words per minute alone assumes you never stop. In a real talk you pause at the end of most sentences, longer at the end of a section, and longer again for a laugh or a slide change. Half a second per sentence is a modest allowance and often adds ten to fifteen percent to the total; a full second is closer to what a measured keynote speaker actually does. The tool counts sentences by terminal punctuation, so leaving the pause at zero gives you the pure reading-rate figure, and adding one shows how much the delivery, not the words, is costing you.

The target check. Enter the slot you have been given and the readout shows how many words fit in it at your chosen pace and pauses, then how many you need to cut or how many you have to spare. Cutting is almost always the right direction: speakers routinely overrun, and a script that finishes a minute early never bothered anyone.

Measuring your own pace. The presets are averages and you are not average. Read a paragraph of this page aloud with a stopwatch, count the words with the word counter, and put the result in the custom box. Most people are surprised: nervous speakers speed up, and people who think they speak slowly are usually near 150.

Pace by other yardsticks. The table under the readout shows the same script at every preset so you can see the spread at a glance. A 1,000-word script is about 7 min 40 sec at presentation pace but under 5 min 20 sec for a fast talker, which is the difference between fitting a slot and being cut off.
