Depending on the method of reading used, an average college student reads at a speed between 250 to 700 words per minute. Students who follow what they've traditionally learned in grade school and pronounce each word they read use the "sub-vocalization" method and read at about 250 words per minute.
Students who hear the words that they read are somewhat faster; they use "auditory reading." Those students read at approximately 450 words per minute.
Finally, visual readers are the fastest readers. They comprehend meaning by seeing words in a text. Those readers do not need to hear or pronounce words. They can read at 700 words per minute.
