Methods used
Reading Ease uses 206.835 − 1.015 × words/sentences − 84.6 × syllables/words. Grade Level uses 0.39 × words/sentences + 11.8 × syllables/words − 15.59.
Heuristic limitation
Syllables are estimated algorithmically, so proper names and unusual words can be miscounted. Readability formulas measure surface difficulty, not factual quality, accessibility or comprehension.
