A Lexile® measure represents either an individual's reading ability (a Lexile reader measure) or the complexity of a text (a Lexile text measure). Lexile measures range from below 200L for early readers and text to above 1600L for advanced readers and materials. When used together, Lexile measures help a reader find books at an appropriate level of challenge, and determine how well that reader will likely comprehend a text. When a Lexile text measure matches a Lexile reader measure, this is called a "targeted" reading experience. The reader will likely encounter some level of difficulty with the text, but not enough to get frustrated. This is the best way to grow as a reader - with text that's not too hard but not too easy.
