The fundal height, which is the distance from the pubic symphysis to the top of the uterus (fundus), is an important measurement during pregnancy. It is generally estimated that the fundal height in centimeters typically correlates closely with the gestational age in weeks, particularly after the 20-week mark.

In this case, if the fundal height is noted to be 6 cm above the umbilicus, it is crucial to first determine the approximate height of the umbilicus in relation to the gestational age. During a standard pregnancy, the top of the fundus is usually located at the level of the umbilicus around 20 weeks of gestation. Since the fundal height is 6 cm above the umbilicus, this indicates that the gestational age is greater than 20 weeks.

To further estimate, at approximately 24 weeks, the fundus is about 4 cm above the umbilicus. By the time gestation reaches 26 weeks, the fundus would typically be about 6 cm above the umbilicus. Thus, a fundal height of 6 cm above the umbilicus suggests an estimated gestational age of about 26 weeks.

This relationship between fundal height
