The Average Reading Speed by Age — and How to Improve Yours

The Adult Baseline

The most widely cited figure for adult reading speed is 200–250 words per minute (WPM) for average readers of fiction and non-fiction. A 2019 meta-analysis by Marc Brysbaert, published in the Journal of Memory and Language, analysed 190 studies covering over 18,000 participants and found a mean reading rate of 238 WPM for adults reading non-fiction silently.

For easier material (popular fiction, news articles), the same readers averaged slightly faster — around 260 WPM. For denser academic text, the figure drops to 150–180 WPM. Reading speed is not a fixed property of a person; it varies with the difficulty, familiarity, and genre of the material.

Reading Speed by Age Group

These figures from Carver (1992) and the National Reading Panel (2000) represent silent reading speeds for grade-appropriate material at adequate comprehension. Reading speed for oral reading (reading aloud) is consistently lower — typically 150–180 WPM — because pronunciation imposes a physical speed limit that silent reading does not have.

What Determines Reading Speed

Reading speed is the product of several interacting factors, not a single skill:

Eye movement efficiency

Skilled readers do not read one letter or one word at a time. Their eyes make saccades — rapid jumps between fixation points — and can take in approximately 7–8 characters to the right and 3–4 to the left of the fixation point in a single glance. Between saccades, the eye pauses for 150–250 milliseconds. Reading speed is essentially the rate of saccades × the words captured per fixation.

Poor readers make more frequent fixations, longer pauses, and more regressions (backward eye movements to re-read). Trained readers make fewer, longer saccades and almost no regressions.

Vocabulary and background knowledge

Encountering an unfamiliar word forces the reading process to slow dramatically — the reader must decode the word phonologically, look for contextual clues, and infer meaning. Readers with larger vocabularies encounter fewer unfamiliar words and maintain faster speeds. Background knowledge of the topic has a similar effect: familiar concepts are recognised faster than novel ones.

Subvocalisation

Many readers subvocalise — they "hear" the words in their heads as they read. This is sometimes called the "inner voice" of reading. Subvocalisation limits reading speed because the inner voice can only process text at roughly the speed of speech (130–180 WPM). Some speed reading techniques target subvocalisation reduction, though this has trade-offs for comprehension.

Working memory

Reading comprehension requires holding earlier parts of a sentence in working memory while processing the later parts. Readers with higher working memory capacity can handle longer, more complex sentences at higher speeds without losing comprehension. Age-related decline in working memory is one reason older adults sometimes read more slowly despite having larger vocabularies.

Reading Speed vs. Comprehension

There is a well-documented inverse relationship between reading speed and comprehension. Reading faster generally means understanding less — at least at the margins. The key research finding, from Rayner et al. (2016) in Psychological Science in the Public Interest, is that "speed and comprehension trade off." Readers who push their speed substantially above their natural rate sacrifice comprehension.

The practical implication: the goal of reading development should be to raise both speed and comprehension together through practice and vocabulary building, not to maximise speed at the expense of understanding. A reader who processes 300 WPM with 90% comprehension is more productive than one who processes 600 WPM with 50% comprehension.

How to Improve Your Reading Speed

Evidence-based approaches to improving reading speed:

• Read more. Volume of reading is the strongest predictor of reading speed improvement over time. Simply reading more exposes you to more vocabulary, more sentence structures, and more domain knowledge — all of which reduce friction while reading.
• Expand your vocabulary deliberately. Vocabulary study directly removes the bottlenecks caused by unfamiliar words. Reading in your target field — the one where you want to be faster — is the most efficient vocabulary-building approach.
• Reduce regressions. Consciously trying to avoid re-reading sentences forces your reading system to process more effectively on the first pass. Using a pointer (finger or pen moving along the line) can help by giving the eyes an anchor that prevents regressions.
• Vary your reading pace by purpose. Skimming (for overview), scanning (for specific information), and intensive reading (for full comprehension) are different modes. Expert readers shift between them deliberately, rather than reading everything at the same pace.
