The average head circumference for a one-year-old is typically around 46 to 48 centimeters (about 18 to 19 inches). The average chest circumference for a one-year-old usually ranges from 44 to 46 centimeters (approximately 17 to 18 inches). However, individual measurements can vary based on genetics and growth patterns. It's always best to consult a pediatrician for specific growth assessments.
