Words per minute

Words per minute, commonly abbreviated WPM, is a measure of words processed in a minute, often used as a measurement of typing speed or reading speed.

For the purpose of typing measurement, each word is standardized to be five characters or keystrokes long in English,[1] including spaces and punctuation. For example, the phrase "I run" counts as one word, but "rhinoceros" and "let's talk" both count as two.

Characters per minute (CPMn), a measure of characters processed in a minute, is normally WPM times five for English, so that 20 WPM is 100 CPM.

Alphanumeric entry

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.[2] 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.[3]

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.[4] 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.[3] 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.[5][6][7] As of 2005, 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, and 256 wpm (a record caught on video), achieved by Sean Wrona, on TypeRacer. Wrona also maintained 174 wpm on a 50-minute test taken on[8]


Stenotype keyboards enable the trained user to input text as fast as 225 wpm or faster at very high accuracy for an extended period of time, which is sufficient for real-time activities such as court reporting or closed captioning. While dropout rates are very high—in some cases, only 10%[9] or even less graduate—stenotype students are usually able to reach speeds of 100–120 wpm within six months, which is faster than most alphanumeric typists. Guinness World Records[10] gives 360 wpm with 97.23% accuracy as the highest achieved speed using a stenotype.

Numeric entry

The numeric entry or 10 key speed is a measure of one's ability to manipulate the numeric keypad found on most modern separate computer keyboards. It is used to measure speed for jobs such as data entry of number information on items such as remittance advice, bills, or checks, as deposited to lockboxes. It is measured in "Keystrokes per hour," or KPH. Many jobs require a certain KPH, often 8,000 or 10,000.


The average human being hand-writes at 31 words per minute for memorized text and 22 words per minute while copying.[11]

Using stenography (shorthand) methods, this rate increases greatly. Handwriting speeds of up to 350 wpm have been achieved in shorthand competitions.[12]

Reading and comprehension

Words per minute is a common metric for assessing reading speed and is often used in the context of remedial skills evaluation, as well as in the context of speed reading, where it is a controversial measure of reading performance.

A word in this context is the same as in the context of speech.

The average adult reads prose text at 250 to 300 words per minute. While proofreading materials, people are able to read at 200 wpm on paper, and 180 wpm on a monitor.[13] [Those numbers from Ziefle, 1998, are for studies that used monitors prior to 1992. See Noyes & Garland 2008 for a modern tech. view of equivalence]

Speech and listening

Audiobooks are recommended to be 150–160 words per minute, which is the range that people comfortably hear and vocalize words.[14]

Slide presentations tend to be closer to 100-125 wpm for a comfortable pace,[15] auctioneers can speak at about 250 wpm, and the fastest speaking policy debaters speak from 350[16] to over 500 words per minute.[17] Internet speech calculators show that various things influence words per minute including nervousness.

John Moschitta, Jr., was listed in Guinness World Records, for a time, as the world's fastest speaker, being able to talk at 586 wpm.[18] He has since been surpassed by Steve Woodmore, who achieved a rate of 637 wpm.[19]
