Reading Time Calculator
Estimate how long a text takes to read silently, read aloud, or skim from its word count, plus a handy page-count and reading-speed reference.
Comment utiliser cette calculatrice
- 1Enter the number of words in the text.
- 2Optionally adjust the reading speed to match yours — the default is the adult average.
- 3Read the estimated time for silent reading, reading aloud, and skimming.
- 4Use the page estimates to gauge length in printed or manuscript pages.
Comment ça marche
Reading time
time (minutes) = word count ÷ reading speed average silent reading ≈ 238 words per minute reading aloud ≈ 150 wpm, skimming ≈ 450 wpm book page ≈ 500 words; double-spaced page ≈ 250 words
Estimating reading time is simple division: the number of words divided by a reading speed in words per minute. The only real question is which speed to use, and that depends on both the reader and the mode. Large studies put the average adult's silent reading speed at around 238 words per minute for general prose, dropping for dense or technical text and rising for light, familiar material. Reading aloud is far slower — a comfortable speaking pace is about 150 words per minute — while practised skimming can exceed 400. The '5 min read' badges on articles are just this calculation applied at an assumed average speed, which is why they are a rough guide rather than a promise.
Exemple détaillé
A 1,000-word article takes about 1,000 ÷ 238 ≈ 4 minutes to read silently at average speed. Read aloud at 150 words per minute, the same text runs closer to 6 minutes 40 seconds — the reason a script that looks short on the page can fill a surprisingly long slot when spoken.

How fast people actually read
Reading speed is more variable than most people assume. A large analysis of reading studies found that adults read general, non-technical prose silently at an average of about 238 words per minute, with most falling somewhere between 175 and 300. That figure drops sharply for difficult material: legal, scientific, or unfamiliar text can slow a reader to half their normal pace, because comprehension, not eye movement, becomes the bottleneck.
The claims made for speed reading — thousands of words per minute — do not survive careful testing. Beyond roughly 500 to 600 words per minute, comprehension falls off steeply, because the eyes and brain simply cannot process meaning any faster; what looks like ultra-fast reading is really skimming, trading understanding for speed. A realistic ceiling for genuine reading with good comprehension is a few hundred words per minute, which is why the default here sits near the measured average rather than an aspirational figure.
Why reading aloud takes so much longer
Silent reading and reading aloud are governed by different limits. When you read silently, the pace is set by how fast you can absorb meaning, and skilled readers can take in words faster than they could ever say them. When you read aloud, the pace is set by the mechanics of speech — forming each word clearly enough to be understood — which caps a comfortable delivery at around 150 words per minute, and slower still for a formal presentation.
This gap matters whenever text is meant to be spoken. Speechwriters, podcasters, and video scriptwriters estimate length from a speaking rate, not a reading rate, or they badly underestimate how long their material runs. A rule of thumb is that a page of double-spaced script is about two minutes of speech. The calculator's 'reading aloud' figure uses a speaking pace precisely so that a script's true spoken length is clear before it is ever delivered.
Turning word counts into pages and read-time badges
Word count is the honest measure of a text's length, but people often think in pages, which are slippery. A page depends entirely on formatting — font size, margins, spacing. As rough conversions, a typical printed book page holds around 500 words, while a standard double-spaced manuscript page (the format publishers and students use) holds about 250. The calculator reports both so you can translate a word count into whichever kind of page you have in mind.
The familiar 'read time' estimate on articles and blogs is this same arithmetic, usually computed at an assumed average speed and rounded to whole minutes. It exists because readers value knowing whether something is a quick skim or a long commitment before they start. Treat it as an order-of-magnitude guide: your own speed, the density of the writing, and whether you stop to take notes can all move the real time well away from the label.
Questions fréquentes
How long does it take to read 1,000 words?
At the average adult silent-reading speed of about 238 words per minute, roughly 4 minutes. Read aloud at a speaking pace of 150 words per minute it takes closer to 6 minutes 40 seconds, and a fast skim can cover it in about 2 minutes.
What is the average reading speed?
For general silent reading, studies put the adult average at around 238 words per minute, with most people between 175 and 300. Dense or technical material is slower, because understanding rather than eye movement sets the pace. Reading aloud is much slower, near 150 wpm.
Is speed reading real?
Only up to a point. Beyond about 500–600 words per minute, comprehension drops sharply, because the brain can't extract meaning any faster. What is marketed as reading thousands of words per minute is really skimming — useful for finding key points, but not full reading with good understanding.
How do I estimate speech length from a script?
Use a speaking pace, not a reading pace. At a comfortable 150 words per minute, a 1,500-word script runs about 10 minutes. A rule of thumb is that one double-spaced page is roughly two minutes of speech. Slow down for formal presentations, where clarity matters more than pace.
