Typing speed is measured in words per minute (WPM), where one word equals five characters including spaces. The average computer user types 35-45 WPM, while proficient typists reach 60-80 WPM, and competitive typists exceed 120 WPM. To measure accurately, use standardized tests like Monkeytype (which offers customizable duration and text type) or 10FastFingers (which includes special characters). Improvement strategies: learn proper touch typing with all ten fingers, practice daily for 15-20 minutes, focus on accuracy before speed (aiming for 98%+ accuracy), use typing test sentences that cover all letters, and gradually increase difficulty by adding punctuation, numbers, and capitalization. Mechanical keyboards with tactile switches can improve typing accuracy by 5-10%.
