The average person types between 38 and 55 words per minute (WPM), with professional typists averaging between 60 and 80 WPM. Some advanced typists can reach speeds above 120 WPM. Typing speed is typically measured in words per minute, with a standard word being five characters long. Practice and correct technique (like touch typing) can significantly improve typing speed. For a precise measurement of how fast one can type, it's best to take an online typing test that calculates words per minute and accuracy. Typically, a typing speed above 55 WPM is considered good for adults, while different jobs may require minimum speeds ranging from 50 to 80 WPM or more. If interested, there are many free online typing tests available to assess and improve typing speed with practice.
