There are several factors that determine penis size, and while some of the top web searches right now are “penis size and country”, or variations thereof, what people may be searching for is evidence that different races have larger penises than others.
Do Certain Races of Men Have Larger Penises?
It’s unknown exactly where this claim originated, but it is a myth. A study published in 2014 revealed that while groups of men measured in Africa, for example, were slightly larger on average, factors like small sample sizes and inconsistent measurement techniques meant there was no conclusive evidence to show differences in average penis size from race to race.
It’s been long debated whether a link exists between race and penis size, but science simply hasn’t confirmed one. The study’s author emphasized that for this question to be answered properly, research must be done methodically — with large enough populations, controlled variables such as height and body weight, and standardized measurement procedures. So far, such a thorough and globally representative study hasn’t been conducted.
What Actually Determines Penis Size?
Penis size is influenced by a combination of genetics, hormones, and developmental factors. Testosterone plays a key role during puberty, as do certain growth factors and receptors that regulate tissue development. Nutrition and overall health can also make small differences, but they’re usually minor compared to what’s inherited genetically.
Interestingly, environmental and psychological factors can affect perceived size, such as stress, body composition, or temperature — all of which can make short-term differences but don’t alter true anatomical length. So while race doesn’t determine penis size, biology does — and most variation falls well within the average range.
How Big Is Big Enough?
Are you out of luck if you don’t have a big penis? Probably not. In a study conducted in 2015, 75 female participants were asked what size of penis they prefer. They were given 3D-printed models representing 33 different dimensions ranging in size from 4 to 8.5 inches (10–21.6 cm) long and 2.5 to 7 inches (5–17.8 cm) in circumference.
Interestingly, the subjects’ preferred size depended slightly on whether the penis belonged to a long-term partner or a one-night stand. For long-term partners, those surveyed chose a penis length of 6.3 inches (16 cm) and a girth of 4.8 inches (12.2 cm). For one-time partners, they chose a slightly larger penis — 6.4 inches (16.3 cm) long and 5 inches (12.7 cm) in circumference.
So, if you’re in the ballpark of 5.3 to 6 inches, you’re not only statistically average but also within an attractive range according to most studies. In other words, size matters far less than confidence, compatibility, and connection.
