As I’ve been curious about my writing’s readability, I’ve run some strictly layman readability tests. The results of the tests indicate I’m hitting my targets. Below are averaged scores from my trilogy and two other books.
Flesch - reading ease formula, 60 – 70 is acceptable
Range: 69.03 – 76, Average: 72.42 Score: Fairly Easy
Flesh-Kincaid - grade-level indicator
Range: 5.29 – 6.65, Average: 5.912 Score: Sixth Grade
FOG - complexity, lower number is better, 6 – 7 is ideal
Range: 6.7 – 8.7, Average: 7.46 Score: Fairly Easy
SMOG - grade-level indicator
Range: 6.09 – 7.89, Average: 7.46 Score: Eighth Grade
ARI - per word understandability, also grade-level indicator
Range: 4.41 – 5.56, Average: 5.03 score: Sixth Grade
Summary:
Based on the findings and the my familiarity with the contents of my books, I’d recommend the minimum age of the reader to be thirteen years old.
Other than the age restriction the books are rated to be just a little more difficult to understand than writing by Mark Twain.
