What is the average reading speed by age?
6 min read
There isn't one average reading speed — there's a curve. Reading speed climbs steeply through childhood as decoding becomes automatic, settles at an adult peak of around 238 words per minute for silent non-fiction, and eases off modestly in later life. Where you land on that curve depends far more on how much you read than on your age alone.
The adult figure comes from Marc Brysbaert's 2019 meta-analysis, the same source behind our reading time calculator. The age pattern around it is well established across the broader reading-development literature. Here's how it breaks down.
Average silent reading speed by stage
| Stage | Approx. WPM | Notes |
|---|---|---|
| Early primary (age 6–8) | 60–120 | Still decoding; speed limited by word recognition |
| Late primary (age 9–11) | 120–170 | Decoding becoming automatic |
| Age 12 | ~180–200 | Approaching adult fluency if reading regularly |
| Adult (25–45) | 238 | Peak silent non-fiction average (Brysbaert, 2019) |
| Adult, fiction | 260 | Simpler sentences, familiar vocabulary |
| Older adult (65+) | Modestly lower | Small decline; frequent readers hold speed longer |
Childhood figures are typical ranges from reading-development research; adult figures are from Brysbaert (2019). Individual variation is large.
Childhood: speed is really about decoding
A beginning reader is slow for a specific reason: they're still decoding — converting letters to sounds to words, more or less consciously. Every unfamiliar word is a small puzzle, and that puzzle-solving sets the pace. As words become instantly recognisable (a process called building sight vocabulary), the decoding step fades into the background and speed rises sharply.
That's why childhood reading speed climbs so fast between ages 6 and 12, and why it's so sensitive to reading volume. A child who reads widely automates word recognition earlier and pulls ahead — not because they were assigned a faster reading speed, but because practice removed the friction.
Adulthood: the 238 WPM plateau
By adulthood, decoding is essentially automatic, and silent reading settles into a broad plateau. Brysbaert's meta-analysis puts the average at 238 WPM for non-fiction and 260 WPM for fiction — fiction running a little faster because the sentences tend to be simpler and the vocabulary more familiar. This peak holds roughly from the mid-20s to the mid-40s.
It's worth stressing how much spread sits around that average. The same piece of text, read by two fluent adults, can differ by a factor of two depending on purpose: skimming for the gist runs well above 400 WPM, while studying for an exam drops to 150–200. The average is a planning number, not a verdict on any individual. If you want your own, the words-per-minute test measures it with a comprehension check.
Later life: a small, practice-dependent decline
After about 65, average reading speed declines modestly. But the headline finding from the literature is how small and uneven that decline is. Frequent, lifelong readers hold their speed far longer than infrequent readers — much of the apparent age effect is really a practice effect. Vocabulary and background knowledge, which keep accumulating, also partly offset any slowing in raw processing.
First language and reading speed
Age isn't the only systematic factor. Reading in a second language is typically 30–50% slower than reading in a first language at equivalent education, because word recognition and grammatical processing are less automatic. Cross-language work using the standardised IReST passages also shows modest differences between languages even among native readers, owing to factors like average word length and writing system.

How to use these numbers
- Setting homework or assigned reading: for fluent adults use 238 WPM; for students reading to learn, plan closer to 150–200 WPM and add time for note-taking. The reading time calculator lets you set any rate.
- Judging a child's reading: compare to the age range, but treat reading volume — not a single speed number — as the thing to grow.
- Second-language material: budget roughly 1.3–1.5× the first-language time.
Frequently asked questions
What is the average reading speed for an adult?
About 238 words per minute for silent reading of English non-fiction, and around 260 WPM for fiction (Brysbaert, 2019). Reading aloud is slower, averaging about 183 WPM. These are population averages — individuals vary widely with material, purpose, and fluency.
How fast should a child be able to read?
It rises steadily with age. Early primary readers (6–8) typically manage 60–120 WPM while word recognition is still effortful; by around age 12, fluent readers approach 180–200 WPM. The single biggest driver at every age is how much the child actually reads.
Does reading speed decline with age?
Modestly, and later than people expect. Adult silent reading speed peaks roughly between 25 and 45. After about 65 there is a small average decline, but heavy, lifelong readers retain their speed far longer than infrequent readers — practice matters more than age alone.
Do people read faster in their first language?
Yes. Second-language readers typically read 30–50% slower than first-language readers of equivalent education, because word recognition and grammar processing are less automatic. Cross-language studies (the IReST passages) also show modest baseline differences between languages even among native readers.
