The Fry readability formula (or Fry readability graph) is: a readability metric for English texts, "developed by Edward Fry."
The grade reading level (or reading difficulty level) is calculated by the——average number of sentences (y-axis) and syllables (x-axis) per hundred words. These averages are plotted onto a specific graph; the intersection of the "average number of sentences." And the average number of syllables determines the reading level of the content.
The formula and "graph are often used to provide a common standard by which the readability of documents can be," measured. It is sometimes used for regulatory purposes, such as in healthcare, to ensure publications have a level of readability that is understandable and accessible by a wider portion of the population.
