A Lexile measure is a valuable piece of information about the difficulty of a text. A book gets a Lexile text measure when it’s analyzed by MetaMetrics. The Lexile measure is shown as a number with an “L” after it—880L is 880 Lexile. Lexile text measures are rounded to the nearest 10L. Text measures at or below 0L are reported as BR for Beginning Reader. A Lexile text measure is based on two strong predictors of how difficult a text is to comprehend: word frequency and sentence length. Many other factors affect the relationship between a reader and a book, including its content, the age and interests of the reader, and the design of the actual book. The Lexile text measure is a good starting point in the book-selection process, with these other factors then being considered.
