Weight for 11 year Olds on the basis of Percentile:

A crucial factor to take into account when estimating the average weight of an 11-year-old is percentiles. Healthcare providers utilize percentiles to evaluate a child’s development in relation to their peers. The median weight for 11-year-olds is represented by the 50th percentile, which usually ranges from 70 to 100 pounds (32 to 45 kilograms). Yet, variables including heredity and way of life might affect a child’s weight. While percentiles can be a useful tool in promoting a child’s healthy growth, individual variances must be considered. Speaking with a pediatrician might offer tailored advice regarding a child’s development.

So, in terms of weight, an 11-year-old child is similar to these remarkable birds, but of course, they’re quite different in many other aspects!
