Understanding Readability Scores
Readability formulas measure the complexity of your text based on factors like word length and sentence structure. Here's what the scores mean:
Flesch Reading Ease
Scores range from 0 to 100. Higher scores indicate easier reading.
- 90-100: Very Easy (5th grade)
- 60-70: Standard (8th-9th grade)
- 0-30: Very Difficult (College graduate)
Flesch-Kincaid Grade Level
Estimates the U.S. school grade level required to understand the text. For example, a score of 8 means an 8th grader can understand it. Aim for 7-9 for general web content.
Gunning Fog Index
Estimates the years of formal education needed to understand the text on the first reading. A score of 12 requires the reading level of a U.S. high school senior.
Tips for Better Readability
