What is the expected fundal height at 20 weeks gestation?

At 20 weeks gestation, the expected fundal height is approximately at the level of the umbilicus. This measurement indicates that the uterus has grown significantly to accommodate the developing fetus. At this stage, the fundus, which is the top part of the uterus, rises to the level of the umbilicus as a result of the growth in size and position as the pregnancy progresses.

This measurement is typically used during prenatal visits to assess fetal growth and development. Fundal height is generally expected to correspond with gestational age by about 20 weeks, meaning that the height in centimeters from the pubic bone to the top of the uterus typically equals the number of weeks of gestation, plus or minus 2 centimeters. Thus, at 20 weeks, reaching the umbilicus is an accurate expectation and is indicative of normal fetal development and uterine growth.
