How much is a 12-year old supposed to weigh?
Asked by anonymous on May 29, 2009 in Family & Pregnancy

This is a 12-year old girl who is 5’0” tall.


At 5'0", the healthy weight range for a 12-year old girl spans from around 80 to 110 pounds.  The range is wide because kids grow at different rates and will ultimately achieve a variety of adult heights.  In general, the "healthy weight range" for a child is between the 5th and 95th percentile on his/her growth chart. The pediatrician uses the growth chart to monitor your child's growth over time.  The child's growth curve is more important than where she is at any one point.  Ask the pediatrician to interpret the pattern of your child's growth for you.  Read about pediatric growth charts at
