Fundal height
Fundal height is the distance in centimetres measured from the top of your pubic bone to the top of your uterus (the fundus). Your midwife or obstetrician measures it with a tape measure at antenatal visits from around 20 weeks onward. As a rough guide, the fundal height in centimetres usually matches your gestational week, give or take two centimetres. It is a quick, inexpensive way to track whether your uterus is growing as expected. If the measurement is consistently small or large for your dates, your doctor will likely order an ultrasound to investigate further.
What This Means for You
Understanding Fundal height is an important part of your second/third trimester journey. During pregnancy, your care team will use this term regularly. Being familiar with it means you can ask better questions and feel more confident at your antenatal appointments.

Fundal height can be affected by your body shape, the position of the baby, and whether you have excess amniotic fluid, so it is used as a trend indicator rather than a standalone diagnostic tool. Polycystic ovary syndrome and multiple pregnancies can also affect readings.
