Document statistics displayed in this dialog box include the number of characters, words, sentences, and paragraphs in the document. They also include the average number of sentences per paragraph, of words per sentence, and of characters per word.

The readability of a document is often measured in terms of a grade level, and various algorithms can be used to estimate a document's ease of reading. The Readability Statistics dialog box includes the results of three such commonly accepted estimates. The readability estimates in Word consist of the following:

  • Passive sentences, or the percentage of sentences written in the passive voice. Active voice is considered to be more readable, so a high number of passive sentences means higher difficulty.
  • Flesch Reading Ease, or readability based on the average number of syllables per word and the average number of words per sentence. Standard writing averages 60 to 70 on a 100-point scale. The higher the score, the more people can readily understand the document.
  • Flesch-Kincaid Grade Level, or readability based on the average number of syllables per word and the average number of words per sentence. This score indicates a gradeschool level. For example, a score of 6 means that a sixth-grader can understand the document. Standard writing is approximately seventh- to eighth-grade level.
