What WPM Actually Measures — and What Counts as Good
Words per minute is a keystroke count wearing a friendlier name. Because real words vary in length, typing tests standardise a "word" as exactly five keystrokes, spaces and punctuation included. Typing 300 characters in a minute is 60 WPM regardless of whether those characters formed short words or long ones. That is why a WPM score from one test can be compared against another.
This page reports two numbers because they answer different questions. Raw WPM is everything you typed divided by five — your mechanical hand speed. Net WPM counts only the characters that were correct, which is your usable output. The gap between them is the cost of your mistakes, and it is usually the most informative figure on the screen. A raw score of 80 with a net score of 62 says your hands are fast and your accuracy is throwing away almost a quarter of the work.
One point that trips people up: net WPM here is gross speed adjusted for correct characters, not the older penalty formula some exams use, where each error subtracts a full word from the total. The penalty method produces harsher numbers on the same typing. If you are preparing for a specific certification, check which formula it uses before comparing scores.
If you want to practise rather than measure, the typing test page leads on live error highlighting instead of the score. And if your results look inexplicably low, test the hardware before blaming yourself — a dead or chattering key produces exactly the same symptom as bad technique. The keyboard tester checks every key in under a minute.
