READABILITY INDICES

Fog                        : 11.0135
Flesch                     : 44.7292
Flesch-Kincaid             : 9.7054


The Fog index, developed by Robert Gunning, is a well known and simple formula for measuring readability. The index indicates the number of years of formal education a reader of average intelligence would need to read the text once and understand that piece of writing with its word sentence workload.

(words_per_sentence + percent_complex_words) * 0.4

  • 18 unreadable
  • 14 difficult
  • 12 ideal
  • 10 acceptable
  • 8 childish

    The Flesch reading ease score rates text on a 100 point scale. The higher the score, the easier it is to understand the text. A score of 60 to 70 is considered to be optimal.

    206.835 - (1.015 * words_per_sentence) - (84.6 * syllables_per_word)

    The Flesch-Kincaid grade level score rates text on U.S. grade school level. So a score of 8.0 means that the document can be understood by an eighth grader. A score of 7.0 to 8.0 is considered to be optimal.

    (11.8 * syllables_per_word) + (0.39 * words_per_sentence) - 15.59
