SMOG (Simple Measure of Gobbledygook) was created by G. Harry McLaughlin in 1969 and is the most widely used readability formula for health communication.
The score is the years of education needed to comprehend the text. SMOG 7 means a typical 7th grader should understand it.
Unlike Flesch-Kincaid, SMOG is calibrated for 100% comprehension rather than approximate understanding.
SMOG correlates strongly with comprehension among adults reading medical material. It is the recommended formula by the National Institutes of Health (NIH) for evaluating patient education materials.
The original formula expects exactly 30 sentences. This tool scales the polysyllable count proportionally when your text is longer or shorter.
For consumer health communication, aim for SMOG 6–8.
