What’s the normal head circumference limit for adults?
Head size is not purported to grow after age 18, thus measurements at age 18 are utilized. Multiple growth charts have been published by various sources; our center is developing a study to hopefully answer the question “What is a normal adult head size?” Historically our group has used an upper limit of normal for men as approximately 58.0 cm and for women as approximately 57.3 cm. Please email pten@ccf.org if you’d like a copy of the chart found in SMITH’S Recognizable Patterns of Human Malformation published by Nellhaus, G. (Pediatrics, 1968; 41:106).
