Wondering what the normal size of the uterus is

Patient's question:

B: 4.7cm4.7cm2.9cm, endometrium about 0.3cm
Is it considered a small uterus?
Also, my menstrual cycle has been irregular. Thank you, expert

Doctor's answer:

Hello: Normal uterine measurements (cm) for women at different developmental stages:
Longitudinal diameter Anteroposterior diameter Transverse diameter
Prepubertal stage 2.0-3.3 0.5-1.0 0.5-1.0
Pubertal stage 7 4 4
Menopausal stage 3.5-6.5 1.2-1.8 2-1.8
a. The reference values for a normal adult uterus are: longitudinal diameter 5.5-7.5 cm, anteroposterior diameter 3.0-4.0 cm, transverse diameter 4.5-5.5 cm, and cervical length 2.5-3.0 cm;
b. During puberty, the uterine body is approximately the same length as the cervix. In the fertile period, the uterine body is about twice as long as the cervix, and in the elderly stage, it becomes 1:1 again.
