After 20 weeks gestation, fundal height in centimeters roughly equals gestational age in weeks. For a 24-week pregnancy, the fundal height should be approximately:

Explanation:
The main idea is that after about 20 weeks, fundal height in centimeters roughly matches the gestational age in weeks. This happens because the uterus expands about 1 cm per week, so at 24 weeks the distance from the pubic symphysis to the top of the uterus is typically around 24 cm. Slight variations can occur with fetal position, amniotic fluid volume, or maternal body habitus, but 24 cm is the expected estimate at 24 weeks. The other numbers would align with earlier or later gestational ages (20 cm with around 20 weeks, 28 cm with around 28 weeks, 32 cm with around 32 weeks) and are not the best estimate for a 24-week pregnancy.
