Healthy Weight for 18-Year-Olds (5'5") - CDC Guidelines

According to the Centers for Disease Control and Prevention (CDC), the average weight for an 18-year-old girl who is 5ft5 is 126.4 pounds. However, it is important to note that this is just an average, and there is a wide range of healthy weights for girls of this age and height. Some girls may weigh more or less than the average, and this does not necessarily mean that they are unhealthy.
