Get Height Date Of Birth

Highlights. Birth weight and length are positively associated with later height from infancy to adulthood. Both genetic and individual-specific environmental factors influence the association between birth size and later height.

The average normal birth length is defined as the full-term length of a newborn measuring 19-20 inches or 49-50 centimeters. However, a length of around 18.5-20.9 inches or 47-53 centimeters is also considered as normal birth length [1].

The average length for a newborn is 19–20 inches (in) (48.2–50.8 centimeters [cm]) from the top of the head to the heel of the foot, but this can vary. Doctors also consider a range of 18.5–20.9 in (47–53 cm) to be typical. Male babies are also slightly longer than female babies, on average.

The average term infant's length at birth is between 19-21 inches. As would be expected, taller parents tend to produce longer neonates. At the end of their first month, most infants have increased their length by approximately 1 inch. Occasionally, a neonate may "shrink" during the first 2 weeks of age.

One simple way to predict how tall your child will be when they grow up is to take their height at age 2 if they're a boy or 18 months if they're a girl and double it. (Girls grow a little faster than boys.) This method has been around for a long time, but there isn't any scientific research about how accurate it is.

Here's a popular example: Add the mother's height to the father's height in either inches or centimeters. Add 5 inches (13 centimeters) for boys or subtract 5 inches (13 centimeters) for girls. Divide by 2.

Doubling a child's height at age 2 can provide an estimate of how tall that child will be in adulthood. (Boys are usually a little taller than that number and girls a little shorter.) That's because by 2 most children have reached the growth chart percentile they will stay on as they grow.
