Estimated reading time is measured by dividing the total word count by average reading speed (Words Per Minute, or WPM). According to extensive cognitive reading studies (such as Brysbaert, 2019), silent reading speeds for standard adult non-fiction range between 200 and 250 WPM .
Keyword density measures the percentage frequency of a specific word or phrase relative to the total word count: Density = (Keyword Occurrences / Total Words) * 100% .
The Flesch Reading Ease metric evaluates text difficulty based on average sentence length (words per sentence) and average word length (syllables per word). Higher scores signify clearer, more accessible prose:
