Readability Analysis
Please enter at least 5 words to evaluate readability scores.
Flesch Reading Ease
Scores between 60 and 70 indicate plain English understandable by 13-15 year olds. Higher scores (80-100) are very easy, while lower scores (0-30) reflect dense technical writing.
Gunning Fog Index
Estimates the years of formal education needed to understand text on the first reading. Ideal target for general web copy and blogs is usually between 7 and 10.
Automated Readability Index (ARI)
ARI calculates a character-to-word ratio alongside sentence lengths rather than syllables, providing an independent verification of document readability.
