Free Readability Score Calculator
This readability checker analyzes your text using the Flesch-Kincaid readability formula and gives you an instant grade level, reading ease score, estimated reading time, and word count. Whether you are writing blog posts, marketing copy, academic papers, or business emails, checking readability helps ensure your audience actually understands your message.
The tool calculates your Flesch Reading Ease score (0-100 scale where higher is easier to read) and Flesch-Kincaid Grade Level (the US school grade needed to comprehend the text). It also shows average words per sentence and syllable count, two key factors that affect how readable your writing is.
How to Check Readability
- Paste your text into the input area above (or click "Try Example" to see how it works).
- Click "Analyze" to get your Flesch-Kincaid grade level, reading ease score, word count, and estimated reading time.
- Edit your text to shorten sentences or simplify words, then re-analyze to see your improved score.
Why Readability Matters
- Better SEO: Google favors content that matches user reading levels. Pages written at grade 7-8 tend to rank higher for general queries.
- Higher engagement: Readers stay longer on pages they can easily understand. A 1-grade-level improvement in readability can increase time-on-page by 15%.
- More conversions: Clear writing converts better. Landing pages and emails with readability scores of 60+ consistently outperform complex alternatives.
- Complete privacy: Your text never leaves your browser. Everything is calculated client-side, safe for confidential documents.
Readability Score Ranges
Flesch Reading Ease: 90-100 = very easy (5th grade), 80-90 = easy (6th grade), 70-80 = fairly easy (7th grade), 60-70 = standard (8th-9th grade), 50-60 = fairly difficult (10th-12th grade), 30-50 = difficult (college), 0-30 = very difficult (graduate).
Target scores by content type: Social media: grade 5-6. Blog posts: grade 6-8. Business emails: grade 7-9. Technical docs: grade 10-12. Academic papers: grade 12+.

This keeps the workflow fast, reduces mistakes, and helps them deliver on time.
