The Fry Sight Readability Formula
This formula analyzes the frequency of sight words, syllable complexity, and sentence length to measure text difficulty. The formula analyzes familiar sight words and unfamiliar hard words. Unfamiliar words are those that have two or more syllables and are not part of the Fry sight words list. These words are more challenging for readers to decode and understand, thus increasing the text's complexity.

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.
