At approximately what gestational age is the fundal height at the level of the umbilicus?

• A. 18 weeks
• B. 22 weeks
• C. 24 weeks
• D. 20 weeks

Answer: (D)

Fundal height tracks gestational age once the uterus rises into the abdominal cavity. By roughly twenty weeks, the top of the uterus reaches the level of the umbilicus, so the fundal height is about 20 cm corresponding to about twenty weeks of gestation. After this point, the height tends to increase with advancing pregnancy, though exact measurements can vary with factors like maternal body habitus, amniotic fluid volume, fetal position, and whether there is multiple gestation.
