Correlation between ring finger length and athletic abilityFeatured science projectScience project video


This science fair project was conducted to find out if there is any correlation between the ring finger length of women and their athletic ability. The testing was done by comparing the ring finger lengths of athletic girls and non-athletic girls.


Most of the athletic girls will have ring fingers that are longer than their index fingers.

Finger length and athletic capabilities

It has long been observed that men tend to have a longer ring finger than index fingers, while women’s index fingersand ring fingers are usually of equal length. A larger ring-to-index finger ratio in men has been associated with more aggressive behavior and better athletic abilities. As for women, their ring-to-index finger ratios are instead  associated with verbal skills.

Researchers from King’s College, London have studied this phenomenon and it has been  discovered that women who have a longer ring fingers than index fingers, tend to be very successful in athletics and other sports. They were found to be especially good in running events as well as other sports that involved running, such as football, hockey and tennis.

The difference in finger length was initially believed to be determined by the levels of testosterone in the womb. However, later studies have shown that finger length is mostly determined by genetic inheritance, and not by hormone levels. in the womb
