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.
Tips to Improve Readability
- Shorten sentences: Aim for an average of 15–20 words per sentence. Break long sentences into two.
- Use simpler words: Replace multi-syllable words with shorter alternatives ("use" instead of "utilise").
- Write in active voice: "The dog bit the man" reads easier than "The man was bitten by the dog."
- Avoid jargon: Technical terms lower readability. Define them or use plain language equivalents.
- Use subheadings and lists: Breaking content into sections improves perceived readability.
