What Are the Average Measurements of a Normal Uterus?

A normal uterus measures around 7.5 centimeters in length, 5 centimeters wide and 2.5 centimeters in thickness, according to Radiopaedia.org. Measurements may vary depending on the number of pregnancies and may shrink after menopause, reports The Institute for Female Alternative Medicine.

Pregnancies cause the normal size of the uterus to increase, while menopause causes the normal size to shrink to near pre-pregnancy size, explains The Institute for Female Alternative Medicine. During menopause, many physicians may recommend hormone replacement therapy, which could greatly affect certain diseases such as fibroids, which can add to the size of the uterus, according to the Hysterectomy Alternatives and Aftereffects Foundation.

The uterus is an organ that is part of the female reproductive tract, explains Radiopaedia.org. It lies in the lesser pelvis and is hollow, thick-walled and muscular. The shape of a uterus is described as an inverted pear. The uterus is divided into two parts: the body and the cervix.
