Lexical Density Test

The Lexical Density Test is another readability test that is designed to measure the degree of reading difficulty that a text presents. The Lexical (content) density is calculated by the following formula: Lexical Density = (number of different words) (total number of words) 100.

The lexical density of a text is an attempt to measure the proportion of the content (lexical) words over the total words. Texts with a lower density are more easily understood.

A score of 60-70% indicates a text that is lexically dense. A score of 40-50% is indicative of text that is not considered to be dense.
