What Is a Readability Score and Why Does It Matter?

A readability score tells you how easy it is for someone to read and understand your text. It’s calculated using several formulas like Flesch Reading Ease, Gunning Fog Index, SMOG, and others. The higher the score, the easier your content is to understand.

Tools like the Grammarly readability score are popular among writers because they offer instant feedback based on sentence length, word complexity, and paragraph structure. The readability score Grammarly assigns helps writers spot issues and improve flow.

But the question is: how accurate is the Grammarly readability score scale, and are there better tools?

Grammarly Readability Score Scale Explained

When using Grammarly, you’ll notice a readability score out of 100. This score is part of Grammarly's overall content evaluation, and it reflects how understandable your writing is to an average reader.

0-30: Very difficult to read
31-50: Difficult
51-70: Fairly easy
71-90: Easy
