Flesch Reading Ease is a metric that measures the readability of a text based on two factors:

  • Sentence length determined by the average number of words in a sentence.
  • Word length determined by the average number of syllables in a word.

Since it's based on the American Education system, school levels and age ranges may be inaccurate for non-English languages. However, it's still possible to compare the relative readability of two topics written in the same language.

If a metric value is zero, make sure that the project language matches the content language and check the punctuation.
