Frequently Asked Questions
What is the Flesch Reading Ease formula and scoring scale?
The formula is Score = 206.835 - 1.015(Total Words / Total Sentences) - 84.6(Total Syllables / Total Words). Scores between 90 and 100 represent very easy reading (5th grade), 60 to 70 represent standard plain English (8th-9th grade), and scores below 30 indicate dense academic or legal prose.
What is a worked example calculation?
A 30-word passage divided across 2 sentences contains 15 words per sentence. With 45 total syllables (1.5 syllables per word), the formula evaluates: 206.835 - 1.015(15) - 84.6(1.5) = 206.835 - 15.23 - 126.90 = 64.71, indicating standard conversational reading ease.
How are syllables counted in English words?
The algorithm identifies vowel phoneme clusters (a, e, i, o, u, y) while discounting silent trailing vowel patterns such as word-ending silent "e" or inflectional "es" and "ed" endings.
Is my written manuscript uploaded to a remote processing server?
No. All regex text parsing, sentence boundary identification, and score calculations run strictly inside local browser memory.
