Lexiles are the current measure of readability often the text and the reading ability of the person. For the first time, this measure claims a correlation between the two.
Readability formulas are based on word familiarity (semantic) measures by word frequency an/or word length and sentence complexity (synthatic) sentence length. It is smeant to predict text comprehensibility and reading difficulty.
Readability formulas are based on sentence length, syllabication, and word counts. they are typically done by computers with some formulas with more details than others.
