fundal height /fun″dəl/ [L, fundus, bottom; AS, heightho] , the height of the fundus of the uterus, measured in centimeters from the top of the symphysis pubis to the highest point in the midline at the top of the uterus. Fundal height is measured at each prenatal visit with large blunt calipers or with a tape measure. From the twentieth to the thirty-second week of pregnancy the height in centimeters is roughly equal to the gestational age in weeks in a woman with normal body habitus and a vertex presentation. Thereafter the one-to-one ratio often varies, depending on engagement of the fetal head.
