Reading time is calculated by dividing the total number of words by the selected reading speed, then converting the result into minutes and seconds.

For example, 390 words at 130 wpm equals exactly 3 minutes. If the result is not a whole minute, the time is shown as a clean, easy-to-read combination such as 2 min 18 sec.

The average reading speed used here is 130 words per minute, which is a practical benchmark for most online reading experiences.

Choose Slow for more careful pacing, Average for general reading, or Fast for condensed content and quick comprehension.
