These readability tests are used extensively in the field of education. The result translates to a U.S. grade level, making it easier for teachers, parents, librarians, and others to judge the readability level of various books and texts.  

Interpreting your result

Texts for a wide audience generally need an index less than 12. Texts requiring near-universal understanding generally need an index less than 8.

As a rough guide, US grade level 1 corresponds to ages 6 to 8. Reading level grade 8 corresponds to the typical reading level of a 14 year-old US child. Grade 12, the highest US secondary school grade before college, corresponds to the reading level of a 17 year-old.

In addition to the various reading grade level calcs, the Flesch Kincaid Reading Ease score is calculated as well:

  • 90.0–100.0 - easily understood by an average 11-year-old student
  • 60.0–70.0 - easily understood by 13- to 15-year-old students
  • 0.0-30.0 - best understood by university graduates
