The SMOG Readability Calculator helps people check how easy a piece of writing is to read. It gives a score that shows what reading age or school level someone would need to understand the text.

How it works

The tool looks at the number of long words (those with three or more syllables) and the length of sentences. It then gives a reading grade or age. The higher the grade, the harder the text is to read.

Why it matters

Health information is only useful if people can understand it. Many leaflets, websites, and forms are written in complicated language that can be hard for some people to follow. This can lead to misunderstandings and make health inequalities worse.
Using the SMOG calculator helps writers check if their information is clear and suitable for everyone. Making health materials easier to read helps more people understand their care, make informed choices, and stay healthy.
