Pick a duration, then start typing the passage below as accurately as you can.
Words per minute is calculated the standard way typing tests use: every 5 characters typed (including spaces) counts as one "word", regardless of the actual word lengths in the passage, since real words vary so much in length that raw word-counting would be inconsistent between passages.
Accuracy compares what you typed, character by character, against the source passage at the same position — so an inserted or deleted character will shift everything after it and count as a string of errors, just as it would when a person notices they've fallen out of sync with a passage.
The test starts timing on your first keystroke rather than the moment the page loads, so you can read the passage and settle in before the clock starts, and it ends automatically either when time runs out or when you finish typing the whole passage.
Every 5 characters typed (including spaces) counts as one word. Your total correct characters typed, divided by 5, divided by the minutes elapsed, gives words per minute — this is the standard method used by most typing tests.
The timer starts on your very first keystroke, not when the page loads, so you have time to read the passage first.
Each character you type is compared to the same position in the source passage. The percentage of characters that match is your accuracy score.
Average typing speed is roughly 40 WPM. Proficient typists often reach 60-80 WPM, and touch-typing professionals can exceed 100 WPM, usually with accuracy above 95%.
