What is the QuestionWell Readability Score?
QRS estimates the U.S. school grade level needed to read an English text. It combines sentence length and vocabulary difficulty to help you judge whether your writing fits your audience.

QRS = 0.5 × sentence length grade + 0.5 × vocabulary difficulty grade
How should I use the result?
Readability evaluators offer a starting point. Your readers’ background knowledge, the subject, and the way you organize information also affect how easy a text is to understand.
