How the Flesch Reading Ease Score is Calculated
Explanation of the Reading Ease Formula
The Flesch Reading Ease Score is calculated using the following formula:
Reading Ease Score = 206.835 – 1.015 × (total words ÷ total sentences) – 84.6 × (total syllables ÷ total words).
The average sentence length is calculated by dividing the total number of words in a text by the total number of sentences. Likewise, the average number of syllables per word is calculated by dividing the total number of syllables in a text by the total number of words.
