Whether big or small, a man’s hands say a lot about him. Strong, calloused palms suggest that a man works with his hands, spends lots of time outside, or lifts weights. Bruised knuckles may be associated with fighters. And long, dexterous fingers on male hands seem to be common among concert pianists, surgeons, and artists. Or at least that’s what most people would assume. Whether or not those stereotypes about male hands hold true, a man’s hand size can, in fact, reveal a lot about his biology. Studies have proven that whether a man has small hands or big hands, male hand size gives away a ton of information about everything from a man’s athletic ability to his sex life and even penis size.
First, a clarification: When scientists study a man’s hands, they don’t focus much on whether they’re big, small, or average-sized. They’re looking at the proportions of his fingers.
A man’s index finger, compared to his ring finger, tells scientists how much testosterone he may have been exposed to in utero, which influences many behavioral, health, and anatomical outcomes throughout his life. Turns out, men who are overly concerned about the size of their hands should shift their attention to their fingers. Whether you’re a guy with small, large, or average-size man hands, the index and ring finger say a lot more about you than you may realize.
Male Hands Say Something About the Penis
The length of men’s fingers can predict how they treat women, approach sex, and perform at sports. But is the old wives’ tale about penis size being proportional to hand size true? You’re damn right it is. In a sense.
One study, published in the Asian Journal of Andrology, revealed that men with longer ring fingers had proportionally longer penises to match. After considering the age, weight, height, digit ratio, individual finger length, and body mass index (BMI) of 144 men, they found that height and the length of the gap between index and ring fingers were the factors that made a difference.
“Based on this evidence we suggest that the digit ratio can predict the adult penile size,” the study authors wrote. So if you want to confirm what you’re working with, look to your hands.
A Man’s Hands Might Have Something to Do With His Attractiveness
Men with long ring fingers may be more prone to promiscuity because they’re too damn attractive, studies have shown. While definitely not an excuse that’s going to excuse cheating, when researchers had 49 women assess the attractiveness of 49 men, they found that men with longer ring fingers ranked higher than their peers. There’s little beyond this as far as explanation or conjecture, but it’s still a fascinating correlation.
A Man’s Hand Size Predicts How He’ll Treat Women
Men with longer ring fingers are more likely to smile, laugh, compromise, compliment, and listen attentively to women, according to one study of 78 men and 77 women. The longer their ring fingers, the kinder and more attentive the men seemed to be around women. Men with longer index fingers, however, argued a lot with the women in their lives.
Longer Ring Fingers Mean More Sex and Fertility
The same study suggests that longer ring fingers may be linked to male fertility, a contention backed by preliminary research. Other studies indicate that men with longer ring fingers are four times more likely to partner with women who display outward signs of fertility, such as larger breasts and hips and smaller waists. Meanwhile, both men and women who have longer ring fingers may be predisposed to having multiple sex partners, Oxford University research suggests.
Hormones May Make Men and Women Have Different Finger Lengths
Men generally have longer ring fingers than index fingers, but for women it’s the opposite. There are two major factors that could be the cause. It could either be that people with longer fingers (which just happens to usually be men) are more likely to have longer ring fingers. Or exposure to different levels of sex hormones in utero could be the cause.
A new study of 3,802 men and 3,780 women disproves the first hypothesis by finding that there isn’t a correlation between total finger length and whether the index or ring finger is longer. Although this finding isn’t going to give you any insight into your personality or health or penis size, it does support just how important prenatal sex hormones are in determining finger size. And this goes on to influence a lot of other aspects of a man’s life.
A Man’s Ring Finger Hints at His Athletic Ability
Men with longer ring fingers have better hand strength, regardless of their age and body size, a team of father-son researchers found. Several studies echo the sentiment that longer ring fingers are linked with superior athleticism and overall strength.
Hand Size Has Something to Do With a Man’s Cancer Risk
There’s evidence that men with long index digits have a comparatively lower prostate cancer risk.
But a word to the wise: Anyone who advises you to compare the size of your hand to the size of your face wants you to hit yourself. Smack him in the balls.
