How is WPM (words per minute) calculated?
WPM (words per minute) is calculated using a standardised formula where one "word" equals 5 characters — regardless of actual word length. This prevents long words from being penalised and short words from being rewarded.
Gross = (300 ÷ 5) ÷ 1 = 60 WPM Net = 60 − 2 = 58 WPM
The 5-character standard was established by typewriter manufacturers in the early 20th century and has been used universally ever since. It means typing "I am a cat" (10 characters including spaces) counts as 2 words, while "internationalisation" (20 characters) counts as 4 words.
| Characters typed | Time | Errors | Net WPM |
|---|---|---|---|
| 200 | 1 min | 0 | 40 WPM |
| 300 | 1 min | 5 | 55 WPM |
| 400 | 1 min | 10 | 70 WPM |
| 500 | 1 min | 5 | 95 WPM |
| 600 | 1 min | 0 | 120 WPM |
Spaces count as characters in the standard formula. The Typing Speed test uses the standard 5-character definition so your score is directly comparable to any other WPM test.

Quick Answer
WPM = (total characters typed ÷ 5) ÷ minutes elapsed. The "÷5" standardises word length — a "word" is defined as 5 characters regardless of actual word length, so long words don't penalise your score.
