Newborn Weight Standards

Newborns are also divided into full-term infants and pre-term infants. Under normal circumstances, the weight of full-term infants is generally between 2,500 grams and 4,000 grams, and the standard weight is between 3,000 grams and 3,500 grams. The weight of preterm infants is relatively lighter than the normal standard weight, about two kilograms.
