Expert answer:
On average, the normal size of the uterus varies 50 cm³ and 90 cm³, and can reach the 160 cm³ and still be considered normal. The dimensions of the uterus in an adult woman may range from 6 and 9 cm length and the thickness is between 2 and 3 cm. Already the weight of the uterus varies between 25 and 90 g.
It is important to remember that the volume of uterus varies considerably according to the woman's age, number of children, state of pregnancy and hormonal stimulation.
At pregnancy, the normal size (volume) of the uterus increases significantly gestational age:
| Gestational Age (weeks) | Average Uterine Volume (cm³) |
| 6 | 150 |
| 7 | 175 |
| 8 | 200 |
| 9 | 225 |
| 10 | 293 |
| 11 | 300 |
| 12 | 420 |
| 13 | 488 |
| 14 | 525 |
The volume of the uterus is checked during the ultrasound examination performed by the gynecologist or obstetrician.
