Frequently Asked Questions
What is a good Flesch-Kincaid readability score?
Scores range from 0 (very hard) to 100 (very easy). 90–100: very easy, suitable for children. 70–90: easy, plain English for consumers. 60–70: standard, readable by most adults. 50–60: fairly difficult. 30–50: difficult, college level. Below 30: very difficult, professional/academic text. Most web content should aim for 60–70.
How is the Flesch-Kincaid score calculated?
The Flesch Reading Ease formula: 206.835 − (1.015 × average words per sentence) − (84.6 × average syllables per word). A higher score means shorter sentences and simpler words — easier to read. The formula was developed by Rudolf Flesch in 1948 and is the most widely used readability metric in English.
How do I improve my readability score?
The three most effective improvements: (1) Break long sentences into shorter ones — aim for 15–20 words per sentence. (2) Replace complex words with simpler synonyms — "use" instead of "utilise". (3) Use active voice instead of passive. Also: vary sentence length, use subheadings, and add bullet points to reduce wall-of-text paragraphs.
