What is the average length of a full-term newborn?

The average length of a full-term newborn is approximately 20 inches (50 cm). This length is considered typical as it falls within the range of normal sizes for newborns, which generally spans from about 18 to 22 inches (45 to 56 cm).

Understanding this average is important for healthcare providers as it helps in monitoring the growth and development of newborns. A length of 20 inches indicates that the infant is likely within a healthy growth percentile.

Newborn measurements can be influenced by various factors including genetics, maternal health, and gestational age, but 20 inches is the midpoint of the typical range and serves as a reliable reference point in neonatal care.
