Hard words in these categories are easy: Proper Nouns [ ? ]Count hard words based on syllable count (most common). A hard word is 3 or more syllables. X
OR Characters [ ? ]Count hard words based on character count (least common). A hard word has 3 or more syllables and over 9 characters. X
[ ? ]Make all Proper Nouns easy words. Ex: "Baltimore" (hard word → easy word) | Ex: "Johnathan McDonald" (hard words → easy words). We underline these words in pink or green dots. X
Inflected Words [ ? ]Words that became hard words through inflections are easy again. Ex: "happily" (hard word) → "happy" (easy word) | Ex: "sentences" (hard word) → "sentence" (easy word). We underline these words in pink or green dots. X
Dale-Chall Words [ ? ]Any hard word found on Dale-Chall's 3000 word list is considered easy. We underline these words in pink or green dots. X
Common Sight Words [ ? ]Any hard word found on Edward Fry's 1000 common Sight Words list is considered easy. We underline these words in pink or green dots. X

Average Reading Level Consensus Calc
The Average Readability Consensus Calc analyzes your writing and calculates the number of sentences, words, syllables, and characters. Our program plugs these calculations into 8 popular readability formulas. These readability formulas (see below) will let you know the reading difficulty and grade level of your text and help you find out if your audience can read your writing.
The Automated Readability Index
The Automated Readability Index (ARI) is a popular readability formula that measures the ease of English text. It was developed by researchers in the United States Air Force as a tool to gauge the readability of technical manuals and learning materials. ARI computes a readability score based on the average number of characters per word and the average number of words per sentence. It estimates the grade level needed to understand the text.
The Flesch Reading Ease Formula
The Flesch Reading Ease Formula is one of the pioneering readability formulas that is still widely used today. The formula scores words with 1-2 syllables as easy to read, while words with 3+ syllables are more challenging.
The Gunning Fog Index
The Gunning Fog Index measures the readability of English text. The formula calculates a grade level based on the average sentence length and the amount of complex words. Gunning Fog is widely used to score digital content, articles, documents, and classroom textbooks.
The Flesch-Kincaid Grade Level
The Flesch-Kincaid Grade Level is a readability formula that measures the difficulty of English text. It computes both sentence length and word diversity to score the text's readability. It counts long sentences and complex words to show a higher difficulty level. It is a useful tool to judge the readability of texts, namely in educational and publishing contexts.
The Coleman-Liau Index
The Coleman-Liau Index is a readability formula that measures the difficulty of English text. It estimates the grade level needed to understand the text. The Coleman-Liau focuses on the average number of letters and sentences, rather than syllables or complex words. It assumes longer words and longer sentences make the text more difficult to read.
The SMOG Index
The SMOG Index, also known as the Simple Measure of Gobbledygook, is a readability formula designed to estimate the reading level needed to read and understand a text. SMOG is useful for evaluating longer texts, such as articles, reports, or books. The Index is reliable because it focuses on polysyllabic words, which indicate complex vocabulary and sentences.
Linsear Write
Linsear Write scores the difficulty of English text. The U.S. Air Force first developed the formula to calculate the reading ease of technical manuals. Like many useful readability formulas, Linsear Write calculates the U.S. grade level of a text based on sentence length and 3+-syllable words.
FORCAST Readability Formula
FORCAST scores the difficulty of specialized or advanced texts, such as technical materials, documents, manuals, and procedural writings. Unlike other readability formulas that score narrative texts, the FORCAST formula focuses on one-syllable words in a text, which is more relevant for non-narrative texts. FORCAST is ideal for texts above a 6th grade reading level.

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.
