Barbara Blackburn
United States
American Barbara Blackburn achieved a sustained typing speed of 212 WPM (words per minute) using the Dvorak keyboard layout, a Guinness World Record. That translates to roughly 17.6 accurate keystrokes per second. Blackburn used the Dvorak layout rather than the standard QWERTY, as Dvorak places the most frequently used keys on the home row, minimizing finger travel. Considering that most professional typists average 80 to 100 WPM, her speed was more than double the professional norm.
