Frequently Asked Questions
What is the Flesch-Kincaid score?▼
Developed by Rudolf Flesch in the 1940s and later revised with J. Peter Kincaid for the US Navy, the Flesch Reading Ease score (0–100) measures how easy a text is to read based on average sentence length and average syllables per word. Higher = easier. The Flesch-Kincaid Grade Level translates the same formula into a US school grade equivalent (e.g., 8.0 means a typical 8th grader can understand it).
What readability score should I aim for?▼
It depends on your audience. General web content and blogs: aim for 60–70 (plain English). Marketing and landing pages: 70–80 (easy to scan). Technical documentation: 40–60 is acceptable. Academic papers: 20–40. The key insight: even expert audiences prefer clearer writing. Studies show that people read simpler text faster and remember it better, regardless of their education level. Plain language isn't dumbing down — it's respecting your reader's time.
