What is the average weight of a newborn baby?

A normal full term baby (born after 37 weeks) weighs approximately 3.5 kgs or 7 ½ pounds. This average does not take into account a number of issues.

Firstly it does not consider your family history or ethnicity or how much you or your partner may have weighed at birth.

You may be small or tall you may have a family history of small or large babies.

Your baby may come early or late, which can have an effect in the baby’s size.

Or you may have some medical condition which predisposes your baby to be smaller or larger than average such as diabetes. The midwife who is looking after you will observe the size of your uterus and your baby’s growth. Sometimes a growth scan (ultrasound) may be used to help estimate the weight of the baby if this information is needed.
