How fast do you really read?
Read one short passage at your natural pace, then answer five questions. Your speed only counts if you understood it — because reading faster than you comprehend isn't reading faster at all.
When you press start, a passage appears and the clock begins. Read it once, the way you normally would — no re-reading, no rushing. Press "I'm done" the moment you finish, then answer five questions about it. Comprehension below 60% withholds your percentile.
Passage
Five questions on what you just read. Answer from memory — the passage is gone on purpose.
Your reading speed
Percentiles are approximations against adult silent-reading norms (~N(238, 68) WPM) and reflect effective speed — raw pace scaled by comprehension. Speed varies with material difficulty and familiarity, so treat this as one honest data point, not a fixed trait.

What this measures — and what it doesn't

Measures
Effective reading speed
Words per minute on general prose, gated by whether you actually absorbed it. Raw speed alone is easy to fake; effective speed — pace weighted by comprehension — is the number that means something.
-
Method
Timed passage + 5 questions
An original ~240-word passage is timed from reveal to your "done" press. Five multiple-choice questions then test recall. Score below 60% and the percentile is withheld; read implausibly fast and the run is voided.

Result
Raw + effective WPM, percentile
You see raw pace, effective pace, comprehension, and — when earned — a percentile against approximate adult norms (~238 WPM average). The two speeds together tell you whether to push faster or slow down.

Limits
Honest limits
Speed depends heavily on the material — dense or unfamiliar text reads slower for everyone. This isn't a literacy or dyslexia assessment, and a single passage is a rough snapshot. It's a mirror for your own habits, not a verdict.

Before you begin
How is my reading speed measured?
You read a short original passage at your natural pace, then answer five comprehension questions. Your raw speed is the passage's word count divided by the time you spent reading, expressed in words per minute (WPM).
Why does comprehension affect my score?
Because reading faster than you understand isn't reading faster — it's skimming. If you score below 60% on the questions, the percentile is withheld. Your effective speed scales raw pace by comprehension, so fast-but-shallow reading is penalised in proportion.
What is a typical adult reading speed?
Silent reading of general prose averages around 238 words per minute for adults, with a wide spread. We place your effective speed against approximately N(238, 68), so ~238 WPM sits near the 50th percentile and ~300 WPM near the 80th.
Are speed-reading claims of 1,000+ WPM real?
Not with full comprehension of new material. Above roughly 400–500 WPM, comprehension of unfamiliar text drops sharply — what's marketed as speed reading is usually skimming, which has its place but isn't the same thing. This test is built to tell the difference.
