The anatomy of the vagina: what is considered “normal”?
The vagina is an elastic organ, designed to adapt , expand, and contract depending on different circumstances, such as the use of tampons, sexual intercourse, or childbirth. Its average length at rest is between 7 and 10 cm , but it can expand significantly with arousal or during childbirth, up to double its size.

Therefore, there is no “ideal” or “correct” size. Every woman is unique, and her body responds differently.
