Frequently Asked Questions

What is a good Flesch-Kincaid Reading Ease score?

Scores of 60–70 are considered standard (readable by 13–15 year olds). Scores above 70 are easy (plain English). Scores below 30 are very difficult (academic/technical writing). For general web content, aim for 60+.

What is the Gunning Fog Index?

The Gunning Fog Index estimates the years of formal education needed to understand the text on a first reading. A score of 12 means a high school graduate can understand it; a score of 6 is accessible to most readers.
