 FOG index (25 Nov 2003 at 18:39)
The Fog index, developed by Robert Gunning, is a well known and simple formula for measuring readability. The index indicates the number of years of formal education a reader of average intelligence would need to read the text once and understand that piece of writing with its word sentence workload.
18 unreadable
14 difficult
12 ideal
10 acceptable
8 childish
The Flesch readability index, usually between 0 and 100, indicates how difficult the text is to read. Some examples for random material for various publications are:
Comics95
Consumer ads82
Sports Illustrated65
Time57
New York Times39
Auto Insurance Policy10
IRS Code-6


Analysis of sample chapter from my novel:
FOG:185.31
FLESCH:-388.50
KINCAID:178.25


In other words, you can understand my novel if you have 185 years of formal education. In other words, my novel rules!!

Word count: 41600

tom, did you score them yourself based on a rubric or did you use some sort of program to analyse it?

I used a program. I'd hate to count all those words and syllables by hand!
