Measuring a baby's growth in pregnancy

I am often asked how midwives are able to tell a baby's growth during pregnancy without doing an ultrasound. Sometimes an ultrasound can be helpful if a midwife has concerns about a baby's growth, but in most cases, a midwife or doctor is experienced in feeling and measuring the baby to gauge growth.

We are trained in what to look and feel for and how to make sense of this to determine not only a baby’s size, but also its position and to feel for its movements.

Midwives and doctors measure the growth of a baby using a tape measure and by feeling (palpating) the baby. They measure from the top of your uterus to the top of your pubic bone, and this measurement should be within 2cm of the number of weeks pregnant that you are.

If your midwife or doctor has any concerns, they may recommend an ultrasound scan.

A baby’s steady growth during pregnancy is a reassuring sign of the baby’s health and well-being.
