Book Finder For Reading Levels

Finding appropriately challenging books for children to read can be, well, a challenge. Because reading levels are measured in different ways, you’ll find that the same book may be classified for different grade levels and reading abilities.

Let’s look at how two books are leveled by different reading assessment systems: Diary of a Wimpy Kid and Harry Potter and the Sorcerer’s Stone. (Jump below for the full comparison chart.)

According to Lexile scores, Diary of a Wimpy Kid is classified at 950L as a book appropriate for students reading at a mid-4th grade level. Despite being 102-pages longer, Harry Potter and the Sorcerer’s Stone’s 880L Lexile score suggests that kids at a late-3rd grade reading level could successfully read the book.

That doesn’t seem like too much of a difference, but what about another rating system?

Well, the Fountas-Pinnell Guided Reading Level assessment – which uses ten separate text characteristics to determine reading level instead of two criteria like the Lexile system – classifies the 1st Harry Potter book as an appropriate reading challenge for children reading at a late-5th grade level. Diary of a Wimpy Kid, on the other hand, is rated for early 5th-grade reading levels.
