How to use the SMOG calculator
You can use this calculator to check the readability level of your own documents or texts from a website.
It uses a version of the SMOG formula, which gives a score as a "readability level" rather than the American school grade level of the original SMOG test which was created by Harry McLaughlin in 1969. To obtain the most accurate score on longer documents use a sample of at least 100 words from three different places in your document.
For guidance in interpreting the readability score, download the free Readability leaflet: http://www.learningandwork.org.uk/resource/readability/
(SMOG stands for Simplified Measure of Gobbledygook!)
