Readability Score Checker

What is Readability Score Checker

The Readability Score Checker analyzes your text using three established readability formulas. The Flesch Reading Ease score (0–100) measures how easy your writing is to read — higher scores mean simpler text. The Flesch-Kincaid Grade Level maps the same analysis to a US school grade (e.g., grade 8 means an 8th-grader can read it comfortably). The Gunning Fog index estimates the years of formal education a reader needs to understand the text, with emphasis on sentence length and multisyllabic words.

How to use

1. Paste or type your text into the input area.
2. Read the Flesch Reading Ease score (0–100) — aim for 60–70 for general-audience content.
3. Check the grade level to see the minimum schooling a reader needs.
4. Review the Gunning Fog index as a second readability estimate.
5. Shorten sentences and replace complex words to raise your score.

When to use it

Writing patient-facing medication instructions and worried they read too dense? Paste your draft and you might see 41 on the Flesch scale (Difficult, college level). Break the long paragraphs into shorter sentences and swap 'administration of the prescribed dosage' for 'taking your medicine', and you can watch the score climb to 68 (Standard, 9th grade), so a much wider audience can actually follow it.
