What is a Readability Score?
TL;DR: A readability score measures how easy text is to understand, based on factors like sentence length, word complexity, and syllable count. Common scoring systems include Flesch-Kincaid, Gunning Fog, and Coleman-Liau.
The Flesch-Kincaid Grade Level indicates the US school grade needed to understand the text. A score of 8 means an 8th grader can understand it. Most web content should target grade 6-8 for maximum accessibility. Academic writing is typically grade 12-16.
