A study of vagina sizes was recently done by a team of Swiss researchers to determine the measurements of a “normal vulva”. The study was published in the British Journal of Obstetrics and Gynecology, and it was based on data relating to 657 women between the ages of 15 and 84. The data was obtained by measuring patients’ clitoris, perineum, labia majora and labia minora.
While the aim of the study was to determine what is “normal” and average, the study found that there range of shapes and sizes is so wide that it is pointless to try and determine the norm.
Based on the measurements, the average labia minora size was found to be around 4.3 cm, but lengths ranged from between 5 mm and 10 cm long, which reflected a huge variation of 9.5 cm. There was also a big difference between the participants’ labia majora. The average was 8 cm long, but they ranged from 1.2 cm to 18 cm. With regard to the clitoris, the average was close to 7 mm long but they ranged from 0.5 mm to 3.4 cm in length.
The study ultimately confirms that there is no single way to define a “normal vagina”, as the range of diversity in vulva shapes and sizes out there is huge.
