The digit ratio is the ratio of the lengths of different digits or fingers. The 2D:4D ratio is the most studied digit ratio and is calculated by dividing the length of the index finger of a given hand by the length of the ring finger of the same hand. A number of studies have shown a correlation between the 2D:4D digit ratio and various physical and behavioral traits
Ratio = index finger/ring finger. Use the right hand.
For me it is 360/360 = 1, typically female.
Anything above 1 (index finger longer than ring finger) is typically female and indicative of higher prenatal estrogen. Anything below 1 (ring finger longer than index) is typically seen in males and indicative of higher prenatal testosterone.
Women average a 0.98 ratio.
Men average a 0.95 ratio.
