Free Readability Tests using the Fry Graph and Raygor Estimate Graph



Our free Fry Graph and Raygor Graph Readability Tool uses a sample of your writing and processes it through two readability formulas, the Fry Graph and Raygor Estimate Graph. Our free readability tool will visually show you the grade level of your text and help you to decide if your readers can comprehend your materials. Additionally, our readability tool calculates the number of sentences, words, syllables, and characters in your sample.

(Note: We also have a separate readability text tool to calculate your text using 8 popular readability formulas located here: Free Readability Text Tools).

Directions: Paste in a sample of text and click "CHECK TEXT READABILITY." A sufficient sample size consists of 3-4 (100 word) sentences; approximately 300 - 500 words total. For larger texts, such as books, pull 1-2 sample sizes from each chapter. (Note: Our free readability assessment tool limits sample size to 2000 words. Sample sizes over 2000 words are automatically truncated.)

Paste sample of plain text here. Your sample should be between 300-600 words. We do not store or reuse your text in any way.

Our free Fry Graph and Raygor Graph Readability Tool will analyze your text and output the results based on these two readability formulas. Our tool will also help you determine the grade level for your text.

1. The Fry Graph will output a number from 1 to 15 and visually plot its coordinates on a graph between two parallel lines. The number between the two parallel lines represents the U.S. grade level. For example, a score of 8 indicates that the text is understood by an average student in 8th grade.

2. The Raygor Estimate Graph will output a number from 3 to 14 and visually plot its coordinates on a graph between two parallel lines. The number between the two parallel lines represents the U.S. grade level. For example, a score of 6 indicates that the text is understood by an average student in 6th grade. The Raygor Estimate Graph is very similar to the Fry Graph but uses a slightly different calculation.
