What WPM Actually Measures (and Why Accuracy Wins)
"Words per minute" sounds like a simple count, and the way most sites compute it is simple — but the definition of a "word" and what counts toward it changes the number a lot, and it's worth knowing exactly what you're looking at.
A "word" is five characters, not a word
Typed text varies wildly in word length, so almost every typing test — including this one — counts five keystrokes as one "word" for scoring purposes, regardless of where spaces actually fall. Type "cat" and a space, that's 4 characters, 0.8 "words". This is why WPM numbers are comparable across completely different passages: it's really a characters-per-minute measurement wearing a familiar unit.
Raw WPM vs net WPM
Raw WPM counts every keystroke you made, including ones that were wrong. Net WPM counts only the characters that ended up correct in the final text. If you type "recieve" and backspace to fix it to "receive", every keystroke you made — right and wrong — counts toward raw WPM, but only the correct final result counts toward net.
Net WPM is the number that matters, and it's the one this site records. Raw WPM rewards fast, careless typing that gets fixed after the fact; net WPM only rewards what actually ended up on the page. A run where you type 120 wpm raw but backspace constantly can easily net out slower than a clean 70 wpm run with almost no corrections.
Why accuracy dominates at speed
Every wrong character costs you twice: once to type it wrong, once to fix it (a backspace, then the correct key again). At 40 wpm, dropping from 98% to 90% accuracy doesn't cost you 8% of your speed — it costs noticeably more, because each error is 2-3 extra keystrokes you wouldn't have needed, plus the half-second of hesitation most people have right after a mistake. Past a certain point, the fastest way to type faster isn't moving your fingers quicker — it's making fewer mistakes so you never have to stop and fix one.
Consistency: the metric nobody talks about
A wpm figure is one number for an entire run, but typing speed within a run is rarely flat — most people speed up on easy stretches and slow down on hard ones. Consistency measures how much your speed varies moment to moment. Two runs with the same average wpm can feel completely different: one smooth throughout, the other a burst-and-stall pattern. High consistency at a slightly lower average is usually a sign of better underlying technique than a spiky run with a higher peak.
Why every run on this site is server-verified
Because wpm is easy to fake — paste text, or just type a fabricated number — every result here is computed from a full keystroke log, replayed on the server rather than trusted from the browser. That's the only way a class leaderboard, a duel, or a tournament round means anything: everyone's number was produced the same honest way.
