is a formula plus graph to score text readability. The grade levels on the graph range from 1 to 12: 1 is the easiest and 12 is the most difficult. The formula assumes long sentences and words with more syllables make the text hard. The formula can be a helpful tool for educators and publishers to match texts for distinct grade levels or reading skills.

Name | Fry Readability Graph |
Purpose | Assesses the readability of texts for a wide range of grade levels, from 1st grade through college. |
Developed By | linguist Edward Fry |
Main Components | - Average Sentence Length:Counts the number of words in sentences to determine complexity.
- Number of Syllables:Counts syllables in a 100-word sample to measure vocabulary difficulty.
|
Method | - Select three 100-word passages from the text.
- Calculate the average sentence length and the number of syllables in each sample.
- Plot these two values on the Fry Readability Graph to determine the grade level.
|
Grade Level Interpretation | The graph provides a readability score corresponding to U.S. grade levels, from 1st grade to college. |
Uses | - Widely used in education to evaluate textbooks, instructional materials, and other reading content.
- Helpful for teachers, writers, and publishers to match text complexity with the intended audience’s reading level.
|
Benefits | - Simple and quick to apply, requiring only sentence length and syllable count.
- Effective for a broad range of grade levels, making it versatile for educational content.
- Graph-based approach provides a visual interpretation of readability.
|
Example | In a 100-word sample with an average sentence length of 8 words and 120 syllables, these values are plotted on the Fry Graph, resulting in a readability level of approximately 5th grade. |
Our
Readability Scoring System will analyze English-language text and score the "reading ease" or "reading difficulty" of your text based on popular readability formulas. You'll find out the type of readers who are most likely to understand your text, including their grade level and age.
1. GET STARTED Paste your text into the text area or upload a .txt, .pdf, MS-Word, or html file from your computer. For other documents, copy the text to your device's clipboard, then paste into the text area.
2. FOR BEST RESULTS Make sure your text is spell-checked beforehand. Misspellings can alter results. Each sentence should end with a punctuation mark, otherwise run-on sentences can alter results. Abbreviated words should be correctly abbreviated (Mr. or Mrs. not Mr or Mrs). A clean, properly-formatted and grammatically-correct text will yield the best results.
3. SELECT A FORMULA If you don't know which readability formula is best suited for your text, then use our
Average Reading Level Consensus Calc. It will automatically select (9) popular formulas suited for all types of text. For a word-based formula, most writers prefer the Dale-Chall Formula because it can score any type of text. For a graph-based formula, the Fry Graph is widely-used. Otherwise, experiment with different formulas.
4. FINE-TUNE OUR SYSTEM Open the "System Settings" (below the formulas) and change default settings to fine-tune how the scoring system processes your text. Click on any [ ? ] to get more information about the option.
5. READY, SET, GO! When you're ready, hit the "Calculate Text Readability" button. Our system will analyze and score your text and output the information on a new page.
6. WORD STATS ONLY If you need a fast way to see "Word Statistics" for your text, import your text and click on the "Text Statistics" tab. The app will process your text and output important stats, such as syllable count, average sentence length, number of abbreviations, proper nouns, passive voice, etc.
