The vaginal canal is on average about 9 to 10 centimeters (approximately 3.5 to 4 inches) long when not aroused, though it can vary widely among individuals, ranging anywhere from about 5 to 14 cm (2 to 5.7 inches). During sexual arousal, the vaginal canal lengthens and can nearly double in size to accommodate penetration. It is a highly flexible and elastic muscular canal that can stretch other times, such as childbirth, and change with age and hormonal status as well.

Average Length and Variability

• Average vaginal length generally measures around 9 to 10 cm.
• Ranges can vary widely from about 5 cm (2 inches) up to over 13-14 cm (5 to 5.7 inches).
• The vaginal canal is narrow at the opening (about 1.7 cm wide) and wider near the cervix (up to 4.5 cm wide).

Changes with Arousal and Life Stages

• The vagina can elongate during sexual arousal, often nearly doubling in length.
• Hormonal changes from puberty to menopause affect vaginal length and elasticity.
• Pregnancy and childbirth drastically increase vaginal canal size temporarily.

Additional Notes

• Vaginal depth varies from individual to individual and changes throughout the menstrual cycle, menstrual status, and sexual activity.
• The vaginal canal is muscular and adaptable to accommodate sexual intercourse and childbirth.
