A uterine fibroid measuring 2.5 x 2.4 x 2.3 centimeters is about the size of a large grape, according to Fibroids. Most doctors use comparisons to foods or other objects to help patients visualize better.
Doctors measure uterine fibroids in terms of centimeters, but this can be confusing for patients who use standard measurements. Using the longest measurement of 2.5 cm, this fibroid is just under 1 inch long. Doctors may also try to describe the fibroid in terms of how large it makes the uterus and comparing that to how large the uterus is at various stages of pregnancy, as stated by the Office on Women's Health.
