Auditory reading: hearing out the read words. This is a faster process. Visual reading: understanding the meaning of the word, rather than sounding or hearing. This is the fastest process.

What is the best reading speed?

A normal rate for learning is 100-200 wpm, and for comprehension it is 200-400 wpm. Speed reading is normally done at a rate of around 400-700 wpm. Anything above 500-600 wpm means sacrificing comprehension, although this varies from person to person.

What is considered a fast reading speed?

High school or college students who need to memorize or learn the material they're reading typically go through 100 to 200 words in a minute. Anything above 400 wpm is fast reading, while a reading time of 700 wpm falls under speed reading.
