How much does an ordinary 12 year old girl weigh?

There is no "ordinary" weight for a 12-year-old girl, as children develop at different rates. According to the Centers for Disease Control and Prevention (CDC), the average weight for a 12-year-old girl is between 75 and 140 pounds (34 and 64 kilograms). However, some girls may weigh more or less than this range and still be considered healthy. It is important to note that weight is just one factor in assessing a child's health and should not be used alone to determine if a child is overweight or underweight. Other factors, such as body mass index (BMI), body composition, and growth patterns, should also be considered. If you are concerned about your child's weight, talk to your child's doctor.
