The tool implements two proven readability formulas. The Flesch Reading Ease formula: 206.835 - 1.015 × (Total Words / Total Sentences) - 84.6 × (Total Syllables / Total Words). The Flesch-Kincaid Grade Level formula: 0.39 × (Total Words / Total Sentences) + 11.8 × (Total Syllables / Total Words) - 15.59. These calculations provide a reliable measure of text complexity, empowering writers to improve clarity.
What is a good readability score?
For most online content, a Flesch Reading Ease score of 60-70 is great. This means your text is easily understood by the average reader (around an 8th-grade level).
Is a higher grade level better?
Not always. Simpler is often better. A high grade level means your text is complex, which can alienate readers. Aim for a grade level that matches your target audience.
Is my text private?
