Fog index

Apparently the Fog Index is a measure of clarity in writing – writing with a high fog index will be difficult to understand; with a score of 50 meaning your writing is unreadable. Clear writing has a fog index of between nine and 12.

To calculate: Take an extract of 100 words, don’t count proper nouns and hyphenated words are one word.


Fog index = (X+Y) x 0.4

X = average number of words per sentence
Y = words with three or more syllables unless they are plural or in a particular tense like ‘achieving’.


Who the hell worked that out?

Fog index of 100-word extract below = (3+33) x 0.4 = 14.4 If I remove a few of the "etc" (4 syllable word) then I can get it really clear:

"and and and. and and and. etc etc etc. and the the. etc etc. and pig twat fog loon. etc etc. and and and. and and and. etc etc etc. and the the. etc etc. and pig twat fog loon. etc etc. and and and. and and and. etc etc etc. and the the. etc etc. and pig twat fog loon. etc etc. and and and. and and and. etc etc etc. and the the. etc etc. and pig twat fog loon. etc etc. and and and. and and and. etc etc etc. and the the. etc etc. and pig."
