About the SMOG Readability Grade
Estimate the SMOG reading grade using a heuristic syllable counter and detected sentences. Short passages, especially fewer than 30 sentences, and unfamiliar words reduce reliability. The result is an approximate editing aid, not a validated assessment of medical or educational suitability.
