Wpm

Words per minute, commonly abbreviated WPM, is a measure of words processed in a minute, often used as a measurement of the speed of typing, reading or Morse code sending and receiving.

Since the length or duration of words is clearly variable, for the purpose of such measurement, the definition of each word is often standardized to be five characters or keystrokes long in English, including spaces and punctuation. For example, under such a method applied to plain English text the phrase "I run" counts as one word, but "rhinoceros" and "let's talk" would both count as two.

Brandon Raziano found that one study of average computer users in 1998, the average rate for transcription was 33 words per minute, and 19 words per minute for composition. In the same study, when the group was divided into "fast," "moderate," and "slow" groups, the average speeds were 40 wpm, 35 wpm, and 23 wpm, respectively.

With the onset of the era of desktop computers, fast typing skills became much more widespread.

An average professional typist types usually in speeds of 50 to 80 wpm, while some positions can require 80 to 95 (usually the minimum required for dispatch positions and other time-sensitive typing jobs), and some advanced typists work at speeds above 120 wpm. Two-finger typists, sometimes also referred to as "hunt and peck" typists, commonly reach sustained speeds of about 37 wpm for memorized text and 27 wpm when copying text, but in bursts may be able to reach much higher speeds. From the 1920s through the 1970s, typing speed (along with shorthand speed) was an important secretarial qualification and typing contests were popular and often publicized by typewriter companies as promotional tools.

The fastest typing speed on an alphanumeric keyboard, 216 words in one minute, was achieved by Stella Pajunas in 1946 on an IBM electric. As of 2005^[update], writer Barbara Blackburn was the fastest alphanumerical English language typist in the world, according to The Guinness Book of World Records. Using the Dvorak Simplified Keyboard, she maintained 150 wpm for 50 minutes, and 170 wpm for shorter periods. Her top speed was 212 wpm. Current online records of sprint speeds on short text selections are 290 wpm, achieved by Guilherme Sandrini on typingzone.com and 276 wpm achieved by Kathy Chiang on TypeRacer.com. For longer passages, Sean Wrona holds the record with 174 wpm on a 50-minute test taken on hi-games.net.
