How much should a girl weigh and 11 years old?

There is no single ideal weight for an 11-year-old girl. The "average" weight for an 11-year-old girl is usually defined as that of a girl at the 50th percentile on the growth chart. However, this does not account for variation between different body types, genetics, and other individual factors. Healthy weights of 11 year old females can have a large range with girls who are 4ft9in at the 50th percentile weighing around 71lb and 5ft3in girls also at the 50th percentile weighing almost 100lb.

Generally, a healthy weight for an 11-year-old girl is:

- Between 75 and 140 pounds, depending on factors such as height, build, and ethnicity;

- BMI between the 5th and 85th percentiles.

It is important to remember that every girl is different and their unique growth pattern should be considered. Parents should consult with a pediatrician or health professional to assess their child's individual needs and ensure they are within a healthy weight range.
