Readability Formulas Explained
We calculate six industry-standard readability metrics, each using different aspects of your text:
Flesch Reading Ease
The most widely used readability test, scoring from 0-100. Higher scores indicate easier reading. Developed by Rudolf Flesch in 1948, it considers sentence length and syllable count. Most popular content targets 60-70 (readable by 13-15 year olds). The formula is: 206.835 - 1.015(words/sentences) - 84.6(syllables/words).
Flesch-Kincaid Grade Level
Converts the Flesch Reading Ease into a US school grade level. A score of 8.0 means an eighth-grader can understand it. Used by the US military for technical manuals and by many government agencies for public communications.
Gunning Fog Index
Created by Robert Gunning in 1952, it estimates years of formal education needed. It focuses heavily on "complex words" (three or more syllables). For general audiences, aim for 7-8; newspapers typically score 11-12; academic texts score 15+.
SMOG Index
Simple Measure of Gobbledygook, developed by G. Harry McLaughlin in 1969. It's particularly reliable for healthcare and technical documents because it uses polysyllabic word counts. SMOG is often required for patient education materials in the US.
Coleman-Liau Index
Unlike other formulas, it uses letter counts rather than syllable counts, making it faster to compute and more consistent across different writing styles. It's ideal for automated processing of large text collections.
Automated Readability Index (ARI)
A character-based formula developed for real-time monitoring of typewriter output in the 1960s. It produces a grade level score and is particularly useful for technical documentation.
Understanding Your Scores
| Flesch Score | Grade Level | Typical Audience |
|---|---|---|
| 90-100 | 5th grade | Very easy to read. Easily understood by an average 11-year-old student |
| 80-89 | 6th grade | Easy to read. Conversational English for consumers |
| 70-79 | 7th grade | Fairly easy to read |
| 60-69 | 8-9th grade | Standard. Easily understood by 13-15 year-old students |
| 50-59 | 10-12th grade | Fairly difficult to read |
| 30-49 | College | Difficult to read |
| 0-29 | College graduate | Very difficult to read. Best understood by university graduates |
Tips for Improving Readability
- Shorten sentences — Aim for an average of 15-20 words per sentence
- Use simpler words — Replace multi-syllable words with shorter alternatives
- Vary sentence length — Mix short and medium sentences to maintain reader interest
- Use active voice — "The team completed the project" vs "The project was completed by the team"
- Break up paragraphs — Shorter paragraphs are easier to scan and digest
- Know your audience — Technical audiences can handle higher complexity than general consumers
