What Are the Normal Uterine Dimensions?

The size of a normal uterus varies within a certain range. For example, in adult women, the uterus is approximately 7–8 cm in length, 4–5 cm in width at its fundus, and 2–3 cm in thickness, weighing about 40–50 g. Its lower end connects to the vagina. Exact measurements depend on individual factors. Generally, the normal uterine longitudinal diameter measures 5.5–7.5 cm, the anteroposterior diameter 3–4 cm, and the transverse diameter 4.5–5.5 cm; the cervical length is typically 2.5–3 cm.
