Readability Score
Checker

Analyze your text to see how easy it is to read. Our tool uses the standard Flesch Reading Ease formula to grade your content, helping you optimize for user experience and search engines.

Why does it matter? Complex writing can cause users to bounce. Google prefers "helpful content" that is highly accessible. Aiming for an 8th-grade reading level (Score: 60-70) maximizes your audience retention.

How the Readability Score is Calculated

This tool utilizes the industry-standard Flesch Reading Ease formula to determine the complexity of your writing.

The Flesch Formula

The formula weights the average sentence length and average syllables per word. Texts with very long sentences and multi-syllable words receive lower scores (harder to read).

206.835 - 1.015(Total Words / Total Sentences) - 84.6(Total Syllables / Total Words)

Pro Tip: To improve your score instantly, break long sentences into two, and swap out complex words for simpler synonyms.

Understanding the Score

The score typically falls between 0 and 100. A higher score indicates material that is easier to read.

  • 90 - 100: Very Easy (5th Grade)
  • 80 - 89: Easy (6th Grade)
  • 60 - 70: Standard / Ideal (8th/9th Grade)
  • 30 - 50: Difficult (College Level)
  • 0 - 29: Very Confusing (College Graduate)

Frequently Asked Questions

What is a good readability score?

For general web content, blogs, and marketing copy, you should aim for a score between 60 and 70. This equates to an 8th or 9th-grade reading level, which is easily understood by the vast majority of adults.

Does readability affect SEO?

Yes. While readability isn't a direct ranking factor, it heavily influences User Experience (UX). Hard-to-read content leads to high bounce rates and low time-on-page, which signals to Google that your content isn't helpful.

How can I improve my readability score?

The fastest way to increase your score is to shorten your sentences. Aim for 15-20 words per sentence max. Secondly, replace complex, multi-syllable jargon with simpler synonyms (e.g., use "use" instead of "utilize").
