The ratio between the length of the index finger and the ring finger of men's hands is associated with penis length, a study shows. Researchers found that men with a lower ratio, or a shorter length of the index finger compared to the ring finger, tended to have a longer penile length.

i dont think there is any correlation i have big hands, big shoe size 12 and a big nose and i have a micro size penis

Both are way out for me. My hand length is almost 8 ins. Tip of longest finger to where it touches palm is almost 7 ins. At its best it was 5.5 ins erect but now 5 ins is the best I can reach.

Girls I know say that if u have a guy bend his middle finger down as far as he can and mark that spot and extend the finger and measure from the tip of middle finger to the spot that will tell u his penis length. As far as circumfrence idk if they've developed a way to tell yet lol
