to be honest there is no average to this.It all really depends on the persons brain size and capacity.
The size of an average 11-year-old girl's brain is approximately 1,200-1,400 cubic centimeters. At this age, the brain is still developing and growing, with significant changes in structure and function occurring during childhood and adolescence.

The average weight of a 4-year-old's brain is approximately 1,000 to 1,200 grams (about 2.2 to 2.6 pounds). By this age, a child's brain has reached about 80-90% of its adult size, reflecting significant growth and development. Factors such as genetics and nutrition can influence individual variations in brain weight.
The average weight of a twelve-year-old's brain typically ranges from about 1,200 to 1,400 grams (approximately 2.6 to 3.1 pounds). However, individual brain weight can vary based on factors such as genetics, health, and development. By this age, the brain is nearing its adult size, but it continues to undergo important changes in structure and function.
The average weight of a ten-year-old child's brain is typically around 1,200 to 1,400 grams (about 2.6 to 3.1 pounds). By this age, the brain has reached approximately 90-95% of its adult size. Individual weights can vary based on factors like genetics and overall health.
The average height for a 12 year old is 4'11" or 5'0".
