Fundal height, which is the distance between the pubic bone and the top of the uterus, is a crucial measurement used to monitor fetal growth and development during pregnancy. It is measured in centimeters and is typically taken during routine prenatal checkups. The measurement is taken by placing a measuring tape from the top of the pubic bone to the top of the uterus, which can be felt through the abdomen. The fundal height measurement allows healthcare providers to assess the progress of the pregnancy and ensure that the fetus is growing within normal parameters. It should be noted that fundal height measurement is not an exact science, and it can vary slightly depending on the position of the fetus and the skill of the healthcare professional performing the measurement.
Where is Fundal Measured?
Uterine Fundus
The uterine fundus is the rounded, upper portion of the uterus. It is located at the junction of the body and the cervix. The fundus is the thickest part of the uterus and is where the fallopian tubes enter.
Where is Fundal Measured?
The fundal height is measured from the top of the pubic bone to the top of the uterus. It is typically measured in centimeters (cm). Fundal height is used to estimate the gestational age of a pregnancy.
The fundal height can be measured in a number of ways, including:
- Abdominal palpation
- Transvaginal ultrasound
- Abdominal ultrasound

Maternal Abdomen
Fundal height, the distance from the top of the uterus to the pubic bone, is a key measurement during pregnancy. It is used to estimate the baby’s age, position, and growth. Fundal height should be measured regularly throughout pregnancy, usually at every prenatal appointment.
Procedure
To measure fundal height, the healthcare provider will use a measuring tape and gently feel the top of the uterus through the mother’s abdomen.
Variations
Fundal height can vary depending on several factors, including:
- Baby’s size
- Baby’s position
- Amount of amniotic fluid
- Maternal weight and body shape
Table of Average Fundal Height Measurements
| Weeks Gestation | Average Fundal Height (cm) |
|---|---|
| 12 | 10-12 |
| 16 | 16-18 |
| 20 | 20-22 |
| 24 | 24-26 |

Note that these are just average measurements, and variations are common.
Measuring Fundal Height with a Measuring Tape
Fundal height, also known as uterine height, is a measurement that tracks the growth of the uterus during pregnancy. It is an important measurement for monitoring fetal development and identifying potential complications.
To measure fundal height using a measuring tape, follow these steps:
- Place the woman in a supine position, with her bladder empty.
- Locate the symphysis pubis, the bony ridge at the front of the pelvis.
- Place the end of the measuring tape at the symphysis pubis.
- Stretch the tape along the midline of the abdomen, over the uterus.
- Measure the distance from the symphysis pubis to the top of the fundus (the top of the uterus).
| Week of Pregnancy | Average Fundal Height (cm) |

| 16 | 17-19 |
| 20 | 23-25 |
| 24 | 27-29 |
| 28 | 31-33 |
