About the Speed Reading Trainer
This speed reading trainer uses rapid serial visual presentation (RSVP): instead of moving your eyes along lines of text, words flash one at a time — or in chunks of two or three — in the same spot on the screen. Paste an article, a chapter or your own notes, choose a speed in words per minute (WPM), and press play. The highlighted focus letter keeps your eyes anchored, and short pauses at commas and full stops give your brain time to wrap up each phrase.
Use it to practise reading at a steady pace, to push your comfortable speed up in small steps, or to get through emails and notes without distraction. The calculator below shows how long a text will take at your chosen speed compared with the average adult silent reading rate of about 238 WPM for non-fiction.
A word of honesty: research on speed reading finds a trade-off between speed and comprehension. RSVP removes eye movements but also removes the ability to glance back, so understanding usually drops at very high speeds. Aim for the fastest pace at which you can still summarise what you read.
With the default inputs, the reading time at this speed is 12s. Change any value above to recalculate instantly.
How to use the speed reading trainer
- 1Paste the text you want to read into the box.
- 2Pick a starting speed about 50 WPM above your normal pace.
- 3Press Play (or the space bar) and keep your eyes on the highlighted letter.
- 4Pause, step back or slow down whenever you lose the meaning.
- 5Raise the speed by 25–50 WPM once you can summarise each passage comfortably.
Formula and method
The text is split on spaces into words and grouped into flashes of one, two or three words. Each flash is displayed for 60,000 ÷ WPM milliseconds per word, so at 300 WPM a single word shows for 200 ms. With punctuation pauses on, a flash ending in a full stop, question mark or exclamation mark stays up for one extra beat and a flash ending in a comma, semicolon or colon for half a beat.
Reading time is the total number of beats multiplied by the flash time. Because pauses add time, the effective speed is slightly lower than the speed you set. The comparison uses 238 WPM, the average silent reading rate for English non-fiction found in Brysbaert’s 2019 meta-analysis of 190 studies.

Worked examples
Sample paragraph at 300 WPM
The 55-word sample has 4 sentence endings (1 extra beat each) and 3 commas or colons (half a beat each), so 55 + 5.5 = 60.5 beats × 200 ms = 12.1 seconds. That is an effective 273 WPM, against about 13.9 seconds at the average 238 WPM.
Two-word chunks at 400 WPM
55 words in pairs make 28 flashes, each shown for 60,000 × 2 ÷ 400 = 300 ms. Two flashes end a sentence (one extra beat each) and two end in a comma or colon (half a beat each), so 28 + 3 = 31 beats × 300 ms = 9.3 seconds.
500 WPM without pauses
Without pauses, 55 words × 120 ms = 6.6 seconds — exactly 500 WPM, and about 7.3 seconds quicker than reading at the average rate.
Frequently asked questions
What is RSVP speed reading?+
Rapid serial visual presentation shows text one word (or a few words) at a time in a fixed position, so your eyes do not have to move along the line. Apps such as Spritz popularised it; this trainer works the same way in your browser with any text you paste.
What is a good reading speed?+
A 2019 meta-analysis by Marc Brysbaert put the average adult silent reading speed at about 238 words per minute for English non-fiction and 260 for fiction. The same review found most adults read non-fiction at 175–300 WPM and fiction at 200–320 WPM, so a speed in that band is normal.
Does speed reading actually work?+
You can learn to read somewhat faster, especially by skimming wisely and practising, but research reviews (such as Rayner and colleagues, 2016) find a trade-off: as speed rises well above normal rates, comprehension falls. Very high claims like 1,000+ WPM with full understanding are not supported.
What speed should I start at?+
Start near your normal reading speed — around 250–300 WPM — and increase by 25–50 WPM once you can comfortably retell what you read. If you notice you are just seeing words without meaning, drop back down.
Why are there pauses at punctuation?+
Readers naturally linger at the end of phrases and sentences to integrate meaning. Adding a beat after full stops and half a beat after commas makes RSVP feel more natural and generally helps comprehension, at the cost of a slightly lower effective speed.
Should I show one word or several words at a time?+
One word with a focus letter is easiest to follow at moderate speeds. Two- or three-word chunks show short phrases at once, which can feel more natural and reduces flicker at higher speeds. Try both and keep whichever you understand better.
