Disabled World states that the average weight for an 11-year-old girl is 81.5 pounds. The average height for girls in this age group is 56.7 inches.

Kids Health asserts that girls and boys this age must make healthy food choices that contribute to their growth. A balanced diet for preteens includes protein, whole grains, low-fat dairy, fruits and vegetables. Children this age require 10 to 11 hours of sleep each night, according to Kids Health.

Preteen girls can begin puberty and develop hair in the pubic area and under the arms. The Global Post states that it is also normal for an 11-year-old girl to be enamored with a male celebrity or to want to emulate a female celebrity.
