Why are there older age graphic novels mixed in with picture books? Lexile measure difficulty of reading. Some books get Lexile codes—two-letter designations that appear before the Lexile measure—to give more information about the book relating to its developmental appropriateness, reading difficulty, and common or intended use. Readola uses the base level and does not separate via code letters.
