Flesch-Kincaid Readability Checker

Our free online checker helps you instantly measure how easy (or complex) your text really is. The Flesch‑Kincaid test includes two key scores:

  • Reading Ease: a number between 0–100. Higher means easier to read. Aiming for 60–70 means most adults can digest your message without effort.
  • Grade Level: represents the US school grade reading level required. A score of 8–10 means a 13–15‑year‑old can follow your text easily.

Your writing might be clear, but Flesch‑Kincaid gives you a reality check. Long sentences and polysyllabic words? They drag down your score and make your copy less inclusive.

Many studies show over 99% of marketing emails fail basic accessibility checks. If your writing is hard to read, you could be excluding large groups, people with dyslexia, non‑native speakers, those using screen‑readers, and even risking compliance issues.

That’s why tools like this are so helpful:

  • Paste your text into the checker.
  • See your Reading Ease and Grade Level scores at a glance.
  • Use instant feedback to simplify your writing—shorter sentences, clearer words, better structure.

Now, copy, paste, and discover whether your words are ready for everyone. And if you want more background, check out our full guide on Flesch‑Kincaid metrics and why they matter in marketing.
