How to Check Your English Writing Readability

By ClearWrite Team | June 25, 2026

If you are learning English and want to write clearly, checking your readability score is one of the most useful habits you can develop. Readability scores tell you how easy or difficult your text is to read. Whether you are writing emails, blog posts, or academic assignments, understanding readability helps you communicate more effectively with your audience.

What Is a Readability Score?

A readability score is a number that estimates how easy a piece of text is to read. The most common system is the Flesch Reading Ease score. It ranges from 0 to 100. A higher score means easier reading. For example, a children's book might score 90-100, while a legal document could score under 30.

The score is calculated using two simple things: your average sentence length and the average number of syllables per word. Shorter sentences and simpler words give you a higher score. For instance, "The cat sat on the mat" has short words and a simple structure and would score very high. In contrast, "The feline positioned itself upon the rectangular floor covering" uses longer words and would score much lower. Other formulas like the Gunning Fog Index and Coleman-Liau Index also help. Our ClearWrite Readability Checker uses multiple formulas to give you a complete picture.

What Score Should You Aim For?

For non-native English speakers writing for a general audience, aim for a score between 60 and 70. This is considered "Standard" or "Plain English." Most popular news websites score around 60-65, which means they are accessible to a wide audience. Technical documentation often targets 50-60.

If you are writing for social media or a casual blog, a score of 70-80 works well. This range uses shorter sentences and simpler vocabulary, making your content easy to digest quickly. For professional or academic writing, 40-55 may be appropriate, but try to keep it as clear as possible. Remember that a score of 30 or below is typical for academic papers or legal contracts and may be challenging for general readers to follow.

Why This Matters for English Learners

When you write in English as a non-native speaker, your readers may also be non-native speakers. Using clear, readable English helps everyone understand your message. It is not about dumbing down your writing — it is about communicating effectively. Clear writing shows respect for your reader's time and attention.

Readability also affects how your content performs online. Search engines prefer content that is easy to read. Clear, well-structured text tends to rank higher in search results. Additionally, readers are more likely to share and engage with content they can understand quickly.
