Head makes up about what percent of the body in newborns?

Explanation:
Newborns have a disproportionately large head compared to their body. The head typically accounts for about a quarter of the infant’s total body weight. This reflects rapid brain growth and the relatively smaller trunk and limbs at birth. So the best estimate is roughly 25%. A proportion as high as 30% would overstate the head size for most newborns, while 15% or 10% would be too small to reflect the actual head-to-body proportion.
