1. What is the Gunning Fog Index?

The Gunning Fog Index is a readability test designed to estimate the years of formal education needed to understand a text on first reading. It's commonly used in education, publishing, and communications to ensure content matches the audience's reading level.

2. How Does the Calculator Work?

The calculator uses the Gunning Fog formula:

\[ \text{Gunning Fog} = 0.4 \times \left( \frac{\text{words}}{\text{sentences}} + 100 \times \frac{\text{complex words}}{\text{words}} \right) \]

Where:

\( \text{words} \) — Total number of words in the text
\( \text{sentences} \) — Total number of sentences
\( \text{complex words} \) — Words with three or more syllables (excluding proper nouns, familiar jargon, or compound words)

Interpretation: The result represents the approximate grade level needed to understand the text. For example, a score of 12 means a high school senior could understand it.

3. Importance of Readability Scores

Details: Readability scores help writers tailor content to their audience, improve comprehension, and meet accessibility standards. They're used in education, healthcare, legal documents, and web content.

4. Using the Calculator

Tips: Count words, sentences, and complex words (3+ syllables) in your text. Complex words exclude proper nouns, familiar jargon, or compound words. All values must be positive numbers.
