What is the Flesch-Kincaid Readability Score?
The Flesch-Kincaid readability test is a popular readability formula used to determine how easy or difficult a text is to read. It was developed by Rudolf Flesch in 1948 and later modified by J. Peter Kincaid in 1975. The formula uses the number of syllables, words, and sentences in a passage to compute a score that indicates the text’s complexity.
The Flesch-Kincaid score is used primarily to assess whether your writing is suitable for your target audience. For instance, simple writing for children will have a lower score, while more complex academic texts will have a higher score.
The score typically ranges from 0 to 100, where:
- 90-100: Very easy to read, suitable for children
- 60-80: Easily understood by an average 13- to 15-year-old student
- 0-30: Very difficult to read, suitable for university graduates
The Flesch-Kincaid Readability Calculator helps you determine this score by inputting the number of total words, sentences, and syllables in your text.
