7 Studies Explain What the Size of Man Hands Really Mean

Fingers point to a lot of clues about men's hormones, health, and behavior, research shows.

Men’s hands say a lot about their virility, cancer risk, athletic ability, attitudes toward women, and of course, penis size. (Scientifically speaking, of course). But it’s not about the size of your mitts. The length of the index and ring fingers also play into these calculations, and scientists suspect that this ratio may be a biomarker for how much testosterone fetuses are exposed to while developing in the womb. Simply put, a man’s digits say a lot about him. Here’s what your hands say about you:

Finger Length Predicts How You’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. And the longer their ring fingers were, the more kind and attentive they seemed to become. Men with longer index fingers, however, argued nonstop with the women in their lives. Perhaps that’s why we don’t put wedding bands on our index fingers…

Longer Ring Fingers Mean More Sex And More Fertility

The same data suggests that longer ring fingers may be linked to 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 as well as smaller waists. Meanwhile, both men and women who have longer ring fingers may be predisposed to having multiple sex partners, Oxford University research suggests.

Fingers Might Have to Do With Being Good Looking

Men with long ring fingers may be more prone to promiscuity because they’re too damn attractive, other studies show. It’s no excuse, but when researchers had 49 women assess the attractiveness of 49 men, they found that men with longer ring fingers ranked higher than their peers.

Fingers Show How Athletic You Really Are

Men with longer ring fingers have better hand strength, regardless of their age or body size, a team of father-son researchers found. Several studies echo the sentiment that longer ring fingers are predictive of superior athleticism and overall strength. However, shorter ring fingers are best for watching sports — which may be why the foam hands in the stadium highlight the pointer instead.

They Have Something to Do With Your Cancer Risk

It may seem like guys with long ring fingers have all the fun, but there’s evidence that they’re also predisposed to prostate cancer. Men with long index digits have a comparatively lower cancer risk. But don’t believe anyone who says that the size of your hand in relation to the size of your face has anything to do with cancer. That’s a prankster who wants you to hit yourself.

And, Yes, Your Fingers Say Something About Your Penis

The length of men’s fingers can predict how you treat women, approach sex, and perform at sports, but is the old wives tale about the man downstairs true according to science? You’re damn right it is. One study, published in the Asian Journal of Andrology, revealed that men with longer ring fingers had longer penises to match (no word on girth). 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 gap between index and ring fingers were the other factors that made a difference.

“Based on this evidence we suggest that the digit ratio can predict adult penile size,” study authors write. So if you’re not sure exactly what you’re working with, it’s really all in your hands.
