Reading speed benchmarks

Average adult: 200–250 WPM (words per minute) at 60% comprehension
Good reader: 300–400 WPM
Speed reader: 500–800 WPM (comprehension typically decreases)
Audiobooks: typically 150–160 WPM (natural speech rate)

RSVP (Rapid Serial Visual Presentation)

RSVP displays words one at a time in a fixed position, eliminating the need for saccades (eye movements). This can increase reading speed, but research shows comprehension and retention are lower compared to traditional reading, especially for complex material.

Subvocalization

Most people "hear" words internally while reading (subvocalization), which limits speed to speech rate (~150–300 WPM). Reducing subvocalization is the core goal of speed reading training - though fully eliminating it tends to harm comprehension of dense text.

How to use this tool

Paste or type your text into the input area and set your starting WPM to just above your comfortable reading speed.
Increase your WPM by about 25 per session (roughly once a week), and only advance when comprehension feels solid.
Adjust the chunk size (words displayed at once) - beginners start with 1 word; experienced readers may find 2–3 words at a time faster overall.
After each session, quiz yourself on the material to verify comprehension. If recall drops significantly, reduce WPM and focus on solidifying at the current level.

Research caveats

A 2016 review by Rayner, Schotter, Masson, Potter, and Treiman published in Psychological Science examined speed reading training and found that:

RSVP and other speed reading techniques generally reduce comprehension compared to normal reading at equivalent speeds.
Claims of 1,000+ WPM reading with normal comprehension are not supported by controlled research.
Peripheral vision does not allow meaningful word recognition, so "taking in a whole page" techniques do not work as described.

Speed reading training is most useful for increasing reading rate modestly (from 200 to 300 WPM) while maintaining comprehension. Above 400–500 WPM, comprehension typically degrades.

Eye movement types

Saccades: rapid jumps between fixation points. The eye does not read continuously - it jumps 6–9 letters at a time and lands on the next fixation point.
Fixations: the pauses between saccades where actual word recognition occurs. Average fixation duration is 200–250 ms.
Regressions: backward saccades (right-to-left in English) that occur when a word was misidentified or the reader needs to re-read for comprehension. Skilled readers regress less often, but complete elimination of regressions causes comprehension to suffer.
