A word count turns into a time once you pick a rate. Silent reading of non-fiction averages 238 words a minute in Brysbaert’s 2019 meta-analysis, so a thousand words is about four minutes; read aloud at 130 it is nearer eight. The same count also sizes a slide deck, a page count, or your own measured rate.
How to estimate reading time
The single rate hides real variation. Brysbaert found roughly 238 words a minute for non-fiction and about 260 for fiction, with individuals spread widely around both. Dense technical material with code or equations runs far slower, because readers stop and re-read rather than moving linearly. Speed-reading claims of a thousand words a minute do not survive comprehension testing: what is being measured there is skimming, which is a useful skill and a different one. As a practical matter, the "5 min read" label on an article is doing something other than informing you precisely: it is setting an expectation, and rounding to the nearest minute is entirely adequate for that.
Spoken delivery is a different measurement and roughly half the speed. A prepared script read aloud runs near 130 words a minute, conversation nearer 150, and a nervous speaker will go faster than either — 20 to 30 words a minute above the rehearsed rate is normal, which is how a talk that timed perfectly at home finishes four minutes early. None of the figures here include pauses, slide changes or laughter, so add about a fifth for anything performed in front of people.
A slide deck is timed by what you will say, not by how many slides you have. The slide count only becomes a number once you decide how many spoken words each carries: about 110 for an ordinary slide, far fewer for a title and far more for a results table. Rehearse to roughly ninety percent of your slot, and if you overrun, cut a section instead of speaking faster: the speed-up saves less time than you expect and loses the room.
Measuring your own rate is the honest way to use all of this. Time yourself over at least three passages: difficulty and familiarity move a single reading a long way. Note that typing speed in "wpm" is not the same unit. Typing tests define a word as five characters, so the two numbers are not comparable despite sharing a name.

- Putting a read time on an article
- Checking a speech against the slot you have been given
- Sizing a slide deck to a conference session
- Measuring your own reading or speaking rate with a stopwatch
- Turning a word count into a page count
Questions
About 238 words a minute for adult silent reading of non-fiction, and around 260 for fiction. Individuals vary widely.
About four minutes at the default rate; five if the material is technical.
About seven and a half minutes at 130 words a minute, before you add anything for pauses.
Around 650 at a comfortable pace. Write fewer rather than more; nobody has ever complained that a talk finished early.
Fifteen to twenty light ones, or ten dense ones. Count the words you will say rather than the slides themselves.
One to two minutes on average, with enormous variation: a title slide is seconds and a results table is five minutes.
If your slot includes it, yes. A twenty-minute slot with questions is about fifteen minutes of content.
No. Add roughly a fifth for slide changes, demonstrations and audience reaction.
Almost certainly. Nerves push most speakers 20 to 30 words a minute above their rehearsed rate.
120 to 140 for a presentation. Below 100 sounds laboured; above 160 is hard to follow.
Reading faster is; reading at a thousand words a minute with full comprehension is not. Those claims measure skimming.
No. Typing tests use a standardised five-character word, so the two numbers are not comparable despite the shared unit.
At least three. Difficulty and familiarity move a single result a long way.
Four double spaced or two single spaced, at 12 point with normal margins. The standard manuscript page is 250 words.
Because a page count from words assumes solid prose. Headings, images, tables, block quotes and the space around them take room that no word count can see.
It sets expectations before someone commits. Rounding to the nearest minute is fine for that.
