Lexile Rating of Books

*Warning: Don't forget that the "Grade Interest Level" should also be considered when finding a book that is appropriate. Reading Level and Grade Interest Level can vary widely!



Need to determine a reading level for your book? First try your book title on this site to see if you can come up with a Lexile rating:


The Lexile Framework for Reading

The Lexile Framework measures both reader ability and text difficulty on the same scale, called the Lexile scale. However, there are many factors that affect the relationship between a reader and text, including content, age appropriateness, reader interests, suitability of the text and text difficulty. The Lexile measure of a book -- a measure of text difficulty -- is a good starting point in the book-selection process, with other factors then being considered.


The Lexile Analyzer, developed by MetaMetrics, analyzes text to produce a Lexile measure. You must first register as an educator and then you can type in or upload a scanned txt document and it will give you a lexile level.  You can check the lexile chart on the site to get a grade level equivalent if you want.


Now that you have a Lexile rating, check the chart available on this site to see what the average grade level is for your particular book:


INFOhio Lexile Readability Levels

By checking an article’s Lexile rating, a teacher, librarian, or student can determine the level of reading difficulty and use this information to help select the appropriate resources. The Lexile Scale ranges from 200L for beginning readers to over 1700L for advanced texts. While the Lexile Scale lists the average grade level for a particular range, this may not reflect a student’s actual reading ability or comprehension level.


Here are two other Grade Band samples, one from EBSCO and one from Lexile.com. The Lexile chart includes the new "Stretch Bands" designed for the Common Core State Standards.
