Introduction
Researchers have long seen that men’s ring fingers are significantly larger in their symptoms.
With women, it’s usually the other way around: their indexes are usually larger. They called this
long difference between the index and ring fingers the "2D: 4D ratio".
2D means "second digit" - which is your symbol, and 4D means "fourth digit" - your ring finger.
So, if your point is 2.9 inches long and your ring finger is 3.1 inches long, there is a 2D: 4D
aspect ratio of 0.935 (2.9 / 3.1 = 0.935). A ring finger is considered to be longer compared to the
index finger as a "low 2D: 4D ratio."
