Press start and type the displayed passage as accurately and quickly as you can, and the tool measures your words-per-minute and accuracy live.
WPM = (correct characters typed ÷ 5) ÷ minutes elapsed. Five characters count as one standard 'word', which is the industry-standard method.
Average is around 40 WPM. 60+ WPM is good, 80+ is fast, and professional typists often exceed 100 WPM. Accuracy above 95% matters as much as speed.
