Normal or Average Penis Size?
What is the normal penis size? What is average penis size? These are common questions that many guys have. So, lets take a look. One global study of 15,000 men found that the average flaccid penis is 3.6 inches long and has a girth of 3.66 inches. In the same study the average erect length was 5.16 inches, and the average erect girth was 4.59 inches. Many guys want to know if they have an average penis or if their penis is on the small side. So, Let’s take an in-depth at look at what is considered a normal penis size.
Average measurements were:
Flaccid Length: 3.6 in
Flaccid Girth: 3.66 in
Erect Length: 5.16 in
Erect Girth: 4.59 in
Another study of American men had similar results. Average self-reported erect length was 5.6 inches and girth was 4.8 inches. However, self-reported sizes can be unreliable (duh!). So, let’s look at measurements performed by medical professionals.
In one such study, where men were measures by medical professionals the average penis length was 3.5 inches flaccid and 5.1 inches erect. Interestingly, the study found that the flaccid length did not have any relationship to the eventual erect length. Scientific proof of the saying: “I’m a grower, not a shower.”
Finally, in another study of 800 men undergoing medically induced erections the average erect penis length was 5.6 inches (pubic bone to penile tip) and average erect girth was 4.5 inches.
Interestingly, a 2020 study found that when surveyed men believe average erect length is 6 inches. Notably, this is much more than the true average length of 5.16 inches. Meaning most guys overestimate by almost an inch! No wonder they feel small.

Does Penis Size Vary by Nationality?
Interestingly, average penis does not vary much around the world. Worldwide flaccid length ranges from 2.8 to 3.9 inches and erect length is between 4.7 and 6.3 inches.
Global average measurements were:
Flaccid Length: 2.8–3.9 in
Flaccid Girth: 3.5–3.9 in
Erect Length: 4.7–6.3 in
Erect Girth: 4.7 in
The Reality of Penis Length.
Lets take a look at the real facts about penis length. This ruler shows the range of penis size. The average erect length is 5.5 inches. Significantly, almost 100% of men fall between 3 and 8 inches. Men outside this range are unicorns!
To better understand this let’s talk about standard deviation. Standard deviation is a way to measure how much sizes vary from average. In the case of penis length, the standard deviation is about 0.7 inches. Importantly, this is small. It means there is not a lot of difference in penis size from man to man.
So, plus or minus one standard deviation means 0.7 inches above and 0.7 inches below the average. Thus, one standard deviation covers lengths between 5 and 6 inches. By definition 68% of men fall in this range. In other words, 2/3 of men have a penis length between 5 and 6 inches.
Plus or minus 2 standard deviations includes 95% of men. Imagine all the guys you know. only 5% of them are shorter than 4.1 inches or longer than 6.9 inches. That means 95% of men fall within 4 to 7 inches.
Plus or minus 3 standard deviations includes 99.7% of men. It means you’d have to search for a long time to find someone smaller than 3.4 inches or bigger than 7.6 inches. Only 1 in 666 men are larger than 7.6 inches.

What is the Reality of Penis Girth?
Let’s look at girth measurements and how you compare: Penis Girth Real Facts.
Average erect girth is 4.6 inches. Most men fall between 2.8 inches and 6.4 inches, with sizes outside this range being very rare.
So again, let’s consider standard deviation for girth. Think of standard deviation as a measure of how spread-out sizes are from the average. For girth the standard deviation is 0.6 inches. This is a small range, smaller than for length.
Plus or minus 1 standard deviation: This means 0.6 inches above and below the average girth. One standard deviation covers girths between 4 and 5.2 inches. This includes 68% of men. In other words, about 70% of men have a girth between 4 inches and 5.2 inches.
Plus or minus 2 standard deviations: This covers 95% of men. Imagine all the men you know. You’d have to look around for a awhile to find someone outside the range of 3.4 inches to 5.8 inches. 95% of men fall within the range of 3.4 to 5.8 inches in girth.
Plus or minus 3 standard deviations: This covers 99.7% of men. It means you’d have to search for a long time to find someone outside the range of 2.8 inches to 6.4 inches. Only 1 in 666 men are larger than 6.4 inches.
How to Measure Penis Size Correctly?
So, if you’re curious about your own size, here’s how to measure it correctly. The correct way to measure is called erect bone-pressed length. For length, press a ruler against your pubic bone and measure from the base to the tip of your erect penis. For girth, wrap a measuring tape around the widest part. Accurate measurements are crucial!

Do Partners Care About Penis Size?
Worried about your length? Don’t be! Studies show that most women don’t consider penis length important. In fact, girth matters more for sexual satisfaction. In a survey, 77% of women said length wasn’t a big deal, while 4 out of 5 women preferred girth over length for better sexual satisfaction.
What Partner’s Want
Preferences for Penis Size
So, what do women want in a penis? A 2015 study asked women to choose from 3D-printed penis models of various sizes. The models ranged in size from 4–8.5 inches in length and 2.5–7 inches in circumference. Interestingly women had different preferences when they considered a long-term partner vs a one-night stand. For long-term partners, the preferred length was 6.3 inches with a girth of 4.8 inches. For one-time partners, they preferred slightly larger sizes. It turns out preferences for one-time partners was a length of 6.5 inches and a girth of 5 inches. Bigger than the average guy and what they want in a long-term partner.
Size Preference:
Long-term partners:
6.3 Length
4.8 Girth
One-time partners:
6.5 Length
5 Girth
What About Gay Men?
Anxiety about penis size isn’t just a straight issue. A survey in the UK found that 38% of gay men worry about their size. A survey of more than 550 gay men by the Gay Men’s Health Project found that 49% think size does not matter, however 37% of guys said it did and 51% of guys says a partner’s size affected the kind of sex they had.
Impact of Obesity and Age on Penis Size
Did you know that your weight can affect how your penis looks? A higher BMI, or more weight can make your penis appear shorter because of extra fat around the base. Losing weight can improve its perceived length. Shedding pounds can be a way to “gain inches.” Age also has a slight impact, but the difference is usually less than 1 cm so very minimal.
Race and Penis Size
Do black men have bigger penises? The idea that black men have larger penises is a myth created by the pornography industry. There is no scientific data to support this claim. Studies that suggest otherwise often rely on self-reported data, which can be unreliable.
In the reliable studies that have examined penis size by country or race, European nations (predominantly white men) tend to show slightly larger averages, around 6.1 inches. In comparison, studies show black men with averages around 5.1 to 5.4 inches.
Asian men, particularly from the Far East and Indian subcontinent, tend to have slightly lower averages, around 4.9 to 5.1 inches.
While there are some differences in average sizes by race, they are not significant. It’s important to remember that these averages apply to populations, not individuals. Penis size can vary widely among individuals, regardless of race. Observations about an individual do not represent their entire racial group.

Does girth matter more than length to gay men?
For bottoms, girth provides more sensation than length. A thicker penis (4.5 inches or more in girth) creates a more full and pleasurable experience than a longer but thinner penis
How do I measure my penis size correctly
- Length: Use a ruler from the base (pubic bone) to the tip while erect. Press the ruler firmly against the pubic bone to account for fat.
- Girth: Wrap a measuring tape around the thickest part of the shaft.
