Understanding Readability Scores

Readability scores measure how easy your text is to read based on sentence length, word length, and syllable count. Lower scores mean harder text; higher scores mean easier text.

Flesch Reading Ease is the most widely used readability formula. A score of 60–70 is considered ideal for general audiences. Most newspapers aim for 50–60; web content should target 60–80.

Gunning Fog Index estimates the years of formal education needed to understand your text. A score of 12 means a Year 12 student can understand it; aim for 8–12 for most audiences.

Automated Readability Index (ARI) uses character count instead of syllables, making it useful for technical and digital content.
