What is Considered a Normal or Average Penis Size?

So, what is the normal or average penis size? Studies across the globe give us a pretty clear picture. A 2014 review involving over 15,000 men over 17 found that the average flaccid penis is about 3.6 inches long and has a girth of 3.66 inches. When erect, the average length is 5.16 inches, and the girth is 4.59 inches.

Average measurements were as follows:
– Flaccid Penis Length: 3.6 in (stretched)
– Flaccid Penis Girth: 3.66 in
– Erect Penis Length: 5.16 in
– Erect Penis Girth: 4.59 in

Another study in the U.S. reported similar results, with an average self-reported erect length of 5.6 inches and a girth of 4.8 inches. Remember, self-reported sizes can be unreliable, so these numbers are more accurate as they come from professional measurements.

The study measured the penile size of 80 males before and after drug-induced erections. In this study, the average penis size was 3.5 inches when flaccid and 5.1 inches erect. The study also found that the size of a person’s erect penis did not correlate with their flaccid penis size. In other words, a penis may have different lengths explaining: I’m a grower, not a shower.

Another study involving almost 800 men aged looked at medically induced erections and found the average penis length was 5.6 inches from the pubic bone to the penile tip, and penis girth was 4.5 inches.

Interestingly, a 2020 research article notes that most men believe the average length of an erect penis is around 6 inches, when in fact, the average is much smaller at 5.16 inches—this is an overestimate of almost an inch!

Does Penis Size Vary by Nationality?

Interestingly, penis size averages don’t vary much around the world. Research from various countries shows flaccid lengths range from 2.8 to 3.9 inches, while erect lengths are between 4.7 and 6.3 inches.

Average measurements were as follows:
– Flaccid Penis Length: 2.8–3.9 in
– Flaccid Penis Girth: 3.5–3.9 in
– Erect Penis Length: 4.7–6.3 in
– Erect Penis Girth: 4.7 in

What is the Reality of Penis Length?

This chart shows a distribution of penis sizes. The average erect length is 5.5 inches. Almost 100% of men fall between 3 and 8 inches, with sizes outside this range being very rare.

Now, let’s talk about standard deviation in simple terms. Imagine standard deviation as a way to measure how spread out the sizes are from the average. In this case, the standard deviation is about 0.7 inches, which is quite small.

When we say “plus or minus one standard deviation,” we mean 0.7 inches above and below the average. So, one standard deviation covers lengths between 5 and 6 inches. This range includes about 68% of men. In other words, almost 70% of men have a penis length between 5 and 6 inches when measured in this way.

Plus or minus 2 standard deviations: This covers 95% of men. Imagine all the men you know or interact with in a normal week. Most likely, you’d have to look around to find someone outside the range of 4.1 inches to 6.9 inches. That means 95% of men fall within 4 to 7 inches.

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 3.4 inches to 7.6 inches. If you’re looking for a man on the larger side, it’s even rarer—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 they vary:

Average erect girth: It’s 4.6 inches. Most men fall between 2.8 inches and 6.4 inches, with sizes outside this range being very rare.

And now again back to Standard deviation: Think of it as a measure of how spread out the sizes are from the average. Here, the standard deviation is about 0.6 inches, which is quite small.

Plus or minus 1 standard deviation: This means 0.6 inches above and below the average. So, one standard deviation covers girths between 4 and 5.2 inches. This range includes about 68% of men. In other words, about 70% of men have a girth between 4 inches and 5.2 inches.

How to Measure Penis Size Correctly?

If you’re curious about your own size, here’s how to measure it correctly. It’s 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 what your partner thinks? 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 45 out of 50 women preferred girth over length for better sexual satisfaction.

Preferences for Penis Size

What about specific preferences? A 2015 study asked women to choose from 3D-printed models of various sizes. The models ranged from 4–8.5 inches in length and 2.5–7 inches in circumference. 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. The preferences for one-time partners are just above the average sizes, but within the normal range.

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 men who have sex with men by the Gay Men’s Health Project found that 49% think size does not matter, and 51% said 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 can make your penis appear shorter because of extra fat around the base. Losing weight can improve its perceived length. 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.
