How to Find the Reading Level of Books

Finding the reading level of a book is crucial for both educators and readers who want to ensure that the material is appropriate for their needs. Whether you’re a student looking for a book that matches your reading level or a teacher trying to assign texts that challenge but do not overwhelm your students, understanding how to determine a book’s reading level can be incredibly helpful. Here’s a detailed guide on how to find the reading level of books.

Using Lexile Measures

Lexile is a reading metric that provides a quantitative measure of text complexity. It’s a number that indicates the difficulty of a text and is often used by educators and librarians to match readers with appropriate books.

Here’s how you can find a book’s Lexile measure:

  1. Check the book’s back cover or inside flap. Many publishers include the Lexile measure on these pages.
  2. Visit the Lexile website and search for the book by title. If the book is not listed, you can use the Lexile Analyzer to estimate the measure.
  3. Use a Lexile decoder to find books that match your Lexile measure. The Lexile website offers a vast database of books and their corresponding Lexile measures.

Using the Flesch-Kincaid Reading Ease Formula

Another method to determine a book’s reading level is by using the Flesch-Kincaid Reading Ease formula. This formula calculates the readability of a text based on the average sentence length and the average number of words per sentence.

Here’s how to calculate the Flesch-Kincaid Reading Ease score:

  1. Count the number of sentences in the text.
  2. Count the number of words in the text.
  3. Count the number of syllables in the text.
  4. Apply the following formula: 206.835 – (1.015 ASL) – (84.6 ASW), where ASL is the average sentence length and ASW is the average number of syllables per word.

Here’s a table showing the Flesch-Kincaid Reading Ease scores and their corresponding reading levels:

Reading Ease Score Reading Level
90-100 Easy
60-70 Fairly Easy
30-50 Standard
0-30 Difficult

Using the Dale-Chall Readability Formula

The Dale-Chall Readability Formula is another tool that can help you determine a book’s reading level. This formula uses a list of 3,000 commonly used words and assigns a readability score based on the number of words in the text that are not on the list.

Here’s how to calculate the Dale-Chall Readability score:

  1. Count the number of words in the text that are not on the Dale-Chall list.
  2. Apply the following formula: 0.39 (number of non-list words) + 11.8 (number of list words) + 15.59.

Here’s a table showing the Dale-Chall Readability scores and their corresponding reading levels:

Readability Score Reading Level
0-5.9 Grade 1-2
6.0-6.9 Grade 3-4
7.0-8.9 Grade 5-6
9.0-10.9
