Understanding Readability Metrics

Flesch Reading Ease Score

This score indicates how easy a text is to read. Higher scores (90-100) indicate very easy-to-read text suitable for 11-year-old students, while lower scores (0-30) indicate very difficult text best understood by university graduates.

• 90-100: Very easy to read, easily understood by an average 11-year-old student
• 80-89: Easy to read
• 70-79: Fairly easy to read
• 60-69: Plain English, easily understood by 13-15-year-old students
• 50-59: Fairly difficult to read
• 30-49: Difficult to read, best understood by college graduates
• 0-29: Very difficult to read, best understood by university graduates

Flesch-Kincaid Grade Level

This score estimates the US school grade level needed to understand the text. A score of 8.0 means an eighth-grader can understand the text. General public documents should aim for a grade level of 7-8.

SMOG Index

The SMOG index (Simple Measure of Gobbledygook) estimates the years of education needed to understand a text. It's particularly accurate for health materials and texts that require 100% comprehension.

Gunning Fog Index

This index estimates the years of formal education needed to understand the text on first reading. A score of 12 indicates the reading level of a high school senior. Popular magazines aim for a fog index of about 12, while technical documents often have scores of 15-20.

Coleman-Liau Index

This index relies on characters instead of syllables, making it ideal for computational analysis. Like other readability formulas, it approximates the U.S. grade level thought necessary to comprehend the text.

Automated Readability Index (ARI)

The ARI assesses the grade level needed to comprehend a text. Unlike other indices, it relies on character count rather than syllables, making it suitable for real-time readability assessment.

Tips for Improving Your Text

• Vary sentence length: Mix short and medium sentences for better rhythm and readability
• Break up long paragraphs: 3-5 sentences per paragraph is ideal for online reading
• Use keywords naturally: Keyword density should typically be 1-2% for main keywords
• Simplify complex words: Shorter words often communicate more effectively
• Structure content wisely: Most readers only retain the beginning and end of content
