Newborn baby weights can vary depending on a variety of factors, but the average weight of a newborn, male or female, is between 5 pounds 8 ounces and 8 pounds 13 ounces. However, baby girls are often smaller than boys at birth, but only slightly.
The optimal size for a newborn is around 4,000 grams, or roughly 8.8 pounds, according to Dr. Kramer. The average baby in the study was found to be smaller than optimal. In 1990, the average birth weight was 3,441 grams, and in 2005 it fell to 3,389 grams, according to the study.
