Sources & methodology

ReadMinutes uses reading-speed values drawn from peer-reviewed research where available, and named industry conventions for measurements (like audiobook narration pace) where research is sparse. This page lists every source behind a number on the site, so you can verify our defaults rather than trust them.

Silent reading — 238 WPM (non-fiction), 260 WPM (fiction)

Brysbaert, M. (2019). How many words do we read per minute? A review and meta-analysis of reading rate. Journal of Memory and Language, 109, 104047.

The standard modern reference for adult silent reading rate. Brysbaert pooled studies of English silent reading and reported a mean of 238 WPM for non-fiction prose and 260 WPM for fiction. These are the defaults the homepage calculator and every reading-time page use.

Reading aloud — 183 WPM (English)

Brysbaert, M. (2019). Same paper. The oral reading rate for English adults is reported at approximately 183 WPM, derived from a separate set of studies pooled in the same meta-analysis. Independently corroborated by Trauzettel-Klosinski & Dietz (2012), who reported ~184 WPM oral reading on the IReST standardized passages.

Speed-reading and the 400 WPM ceiling

Rayner, K., Schotter, E. R., Masson, M. E. J., Potter, M. C., & Treiman, R. (2016). So much to read, so little time: How do we read, and can speed reading help? Psychological Science in the Public Interest, 17(1), 4–34.

The most-cited modern review of speed-reading claims. The authors find that comprehension drops sharply above ~400 WPM regardless of training, and that most claimed “speed reading” gains are skimming rather than full reading. Our words-per-minute test uses this paper's threshold for the “speed reader” bucket.

International reading speeds (cross-language)

Trauzettel-Klosinski, S., & Dietz, K. (2012). Standardized assessment of reading performance: The new International Reading Speed Texts IReST. Investigative Ophthalmology & Visual Science, 53(9), 5452–5461.

Reports reading speeds in 17 languages on the IReST standardized passages. English silent reading on IReST is ~228 WPM and oral reading ~184 WPM. We don't use the IReST values directly, but they independently corroborate the Brysbaert numbers.

Screen reading vs print

Mangen, A., Walgermo, B. R., & Brønnick, K. (2013). Reading linear texts on paper versus computer screen: Effects on reading comprehension. International Journal of Educational Research, 58, 61–68.

Noyes, J. M., & Garland, K. J. (2008). Computer- vs. paper-based tasks: Are they equivalent? Ergonomics, 51(9), 1352–1375.

Together, these studies (and the broader literature reviewed by Noyes & Garland) consistently show that reading from screens is approximately 20–30% slower than reading from print, with modest comprehension cost. The WPM test page references this effect when explaining why your screen reading speed will run lower than your book reading speed.

Audiobook narration pace — 130 / 150 / 170 WPM

Industry convention, not peer-reviewed research.

The narration-speed presets in the audiobook length calculator reflect:

• Audible / ACX narrator guidelines, which recommend 150–160 WPM for standard audiobook narration.
• Audio Publishers Association industry data, which clusters professional audiobook pace around 150 WPM, with dramatic narration as low as 130 WPM and information-dense narration up to 170 WPM.

These are conventions, not measurements. The calculator lets you override with any custom WPM.

Speech-pace presets — 120 / 130 / 155 / 170 WPM

Industry convention, not peer-reviewed research.

The speech presets in the speech time calculator reflect:

• Toastmasters International guidance, which suggests 125–150 WPM for typical public speaking.
• Carmine Gallo's analysis of TED talks (Talk Like TED, 2014), which found an average of ~163 WPM among popular TED speakers; we use 155 WPM as a slightly conservative TED preset.
• National Center for Voice and Speech data on conversational versus presentation speech rates.

Again — conventions, not measurements. Set any custom WPM if your audience or material calls for a different pace.

A note on individual variation

All the WPM numbers on this site are population averages. Individual reading speeds vary substantially with age, fluency, material, and purpose:

• Children build to ~180–200 WPM by age 12 if they are fluent.
• Adult silent reading speed peaks between ages 25 and 45.
• Second-language readers run 30–50% slower than first-language readers of equivalent education.
• Reading speed declines modestly after age 65, but heavy readers maintain their speed much longer than infrequent readers.

If you want to know your own speed, take the reading speed test — it uses a 478-word passage with one comprehension check.
