How It Works

How to Calculate Words Per Minute

WPM measures the speed of reading or typing.

Formula

WPM = Total Words / Minutes

Benchmarks

  • Average reading speed: 200–250 WPM
  • Fast reader: 300+ WPM
  • Average typing speed: 40–50 WPM
  • Professional typist: 70+ WPM

    • Worked Example

    A student reads 500 words in 2.5 minutes.

    word_count = 500minutes = 2.5
    1. 01WPM = 500 / 2.5 = 200
    2. 02Words per hour = 200 x 60 = 12,000
    3. 03Seconds per word = (2.5 x 60) / 500 = 0.30

    Frequently Asked Questions

    What is a good reading speed?

    Average adults read 200–250 WPM. Speed readers can reach 400–700 WPM, though comprehension may decrease at higher speeds.

    How can I improve my WPM?

    Practice regularly, reduce subvocalization (reading aloud in your head), use a pointer or finger to guide your eyes, and expand your peripheral vision.

    Does reading speed affect comprehension?

    Generally, very fast reading reduces comprehension. The optimal speed balances pace with understanding, typically 250–350 WPM for most people.
