Coleman Liau Index

5.89 x (characters/words) - 0.3 x (sentences/words) - 15.8

Automated Readability Index (ARI)

4.71 x (characters/words) + 0.5 x (words/sentences) - 21.43

Coleman Liau and ARI rely on counting characters, words and sentence. The other indices consider number of syllables and complex words (polysyllabics - with 3 or more syllables) too. Opinions vary on which type are the most accurate. In order to count the exact number of syllables a dictionary lookup is needed as there are no hard and fast rules to how many syllables there are in a word.
