How to Check Your English Writing Readability
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.
Tips to Improve Your Readability Score
Here are practical strategies you can apply immediately to raise your readability score:
- Use shorter sentences: Break long sentences into two or three shorter ones. Aim for an average of 15-20 words per sentence.
- Choose simpler words: Use "use" instead of "utilize", "help" instead of "facilitate", and "buy" instead of "purchase". Our Syllable Counter can help you spot overly complex words.
- Avoid passive voice: "The team completed the project" is clearer than "The project was completed by the team." Passive voice adds extra words and reduces clarity.
- Keep one idea per sentence: If a sentence has multiple ideas, split it. For example, instead of "I went to the store and bought milk because we ran out and also needed bread," write "I went to the store because we ran out of milk. I also bought bread."
- Use bullet points and headings: They make text easier to scan and understand. Readers often skim online content, so visual breaks help them find the information they need.
You can also use our Paraphrasing Tool to rephrase difficult sentences into simpler alternatives. And our Text Case Converter helps you format headings and titles correctly, which also improves readability.
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.
