Following which gestational age is fundal height recommended to equal weeks gestation in centimeters?

Fundal height is a key measurement used in prenatal care to assess fetal growth and development. This measurement is taken as the distance from the top of the pubic bone to the top of the uterus (fundus). The guideline that fundal height corresponds with gestational age in centimeters typically begins around 20 weeks.

At this stage of pregnancy, the uterus has grown sufficiently to reach the level of the umbilicus, making it a reliable point to align fundal height with the number of weeks gestation. As the pregnancy progresses, the fundal height will continue to approximate the gestational age, typically within a range of 1-2 centimeters, as the fetus grows in size.

Thus, measuring fundal height starting from 20 weeks is an important milestone in prenatal assessments, helping healthcare providers monitor the growth of the fetus and identify potential complications early on.
