The Flesch-Kincaid Grade Level formula is: 0.39 * (Total Words / Total Sentences) + 11.8 * (Total Syllables / Total Words) - 15.59. The tool counts words, sentences, and syllables to plug into these equations.
What is a good Flesch Reading Ease score?
A score of 60-70 is considered easily understandable by 13-15-year-old students. For a general audience, aiming for a score above 60 is a good goal.
Does a higher grade level mean the writing is better?
Not necessarily. It just means the writing is more complex. The "best" grade level depends entirely on your target audience. For a broad audience, a lower grade level (around 8th grade) is often recommended.
