What is the fundal height and how will it help my doctor check my baby's growth?

How big is your baby each week of pregnancy? The fetal growth chart below will tell you the length and weight of an average baby from eight weeks of pregnancy, through to birth.

Your baby's height and weight is measured carefully each time you get an ultrasound scan. In between scans, your doctor will measure your fundal height (how high in your abdomen your womb has reached) to see if your baby is growing as expected.

If you're not sure how many weeks pregnant you are, see our pregnancy timing article to learn how the weeks of pregnancy are counted. And if you don't know your due date, use our due date calculator to find out.
How are babies measured in the womb?
In pregnancy, a baby's height and weight is measured each time you get an ultrasound scan. From eight weeks to 19 weeks of pregnancy, your baby is measured in length from head to bottom (crown to rump length or CRL). After that he or she will be measured from head (crown) to heel.

In early pregnancy, there is not much difference between pregnancies around the world so the below figures are the international guidelines for growth that doctors in India follow as well. However, Indian babies tend to be slightly smaller at birth than the international average. The average Indian baby weighs anywhere between 2.5kgs and 2.9kgs when born at full term.

What does it mean if my baby is not the right size for his or her stage of pregnancy?
Your doctor will only get concerned about your baby's growth if there is more than two weeks of a difference in height or weight (above or below) for your baby's week of pregnancy.

A baby that is smaller in size by two weeks of what is expected for your stage of pregnancy, might have growth retardation, also called intrauterine growth restriction (IUGR). This is when a health condition prevents the baby from growing as is expected.

A baby that is bigger in size by two weeks of what is expected for your stage of pregnancy, might be growing too fast due to a condition such as gestational diabetes.

Your doctor will want to do more tests and scans to diagnose the condition affecting your baby's size, and will want to ensure that your baby gets all the care he or she needs to grow well.

What is the fundal height and how will it help my doctor check my baby's growth?
In between scans, your doctor will check your fundal height, which measures the height the tip of your womb has reached in your abdomen.

Although she won't be able to know your baby's exact size from this, regularly checking your fundal height will alert your doctor in case your baby is not growing as expected.

Your doctor will either measure your bump from your pubic bone to the tip of your womb with a measuring tape, or just feel with her hands for where the top of your womb is and compare that with what is expected for your stage of pregnancy.

If your doctor uses a measuring tape, your fundal height in centimeters should be roughly equal to the number of weeks you | re pregnant, plus or minus 2cm.

If your doctor uses her hands to check for the tip of your womb, it's called a clinical examination of the fundal height.

Here is a guide to what your doctor will be looking for when she feels for the tip of your womb:



At 12 weeks, your womb will have reached the upper edge of your pubic bone. From there, your womb will grow roughly two finger breadths every two weeks of pregnancy.

It will reach just under your belly button at 22 weeks and just above your belly button at 24 weeks.

At 36 weeks, your womb will have reached its highest point, just under your sternum. It will stay at this height until your baby's head engages and your womb goes down in your abdomen. This can happen up to a month before your delivery for first time pregnant mums, or not until labour with mums who have already given birth.

If your fundal height is more or less than what your doctor expects for your stage of pregnancy, she will ask you to get an ultrasound scan done.
