Human Brain Weight: Facts, Size and Energy Use

Human brain weight facts, including male and female differences, whale comparison, and energy use of human brain weight in the human body.

Human brain weight is the mass of the adult brain, usually 1,300–1,400 grams in males and slightly lower in females. It makes up about 2% of body weight and controls all body functions.
Females generally have 100–150 grams less brain weight than males due to natural biological differences.
A large Swiss study found average brain weights of about 1,340 grams in males and 1,200 grams in females based on autopsy data.
Brain weight varies with age, sex, and body structure and does not determine intelligence.
The heaviest recorded human brain was about 2,850 grams (1899 case in the Netherlands).
Brain weight is highest in young adulthood and slowly decreases with aging.
Compared to other animals, the sperm whale has a much heavier brain (~7,800 grams) than humans.
The brain uses about 20% of the body’s oxygen, making it a highly energy-demanding organ.
Brain weight is an important factor in neurological and aging research.
