What weight is preemie size?

Preemie size is a term used to describe newborns who are born prematurely. This size is usually determined by the baby's gestational age, which is the number of weeks between conception and birth. Preemie babies typically weigh between 1.5 and 7 pounds.

A 1.5lb baby may be born at 22 weeks, whereas a 7lb baby may just be a couple of weeks early. Micro-preemie is a term often used to describe a baby under 3lb. The smallest preemies can be as small as 8 inches long.
