7-Inch Penis: Does Size Really Matter?

Penis size has long been a topic of fascination (along with insecurity, pride, or other tied in emotions, depending on whom you ask and the size in question). According to the limited research available, a 7-inch penis considered larger than average—but, what does that really mean, functionally speaking?

Having a large penis is often glorified, but it can bring certain challenges. For instance, it may make partnered sexual activity more difficult, especially when proper attention isn’t spent on foreplay, or if your partner’s anatomy has trouble accommodating your size.

Again, research on penis size is unreliable. Findings often hinge on self-reported surveys, which tend to yield larger lengths than studies where researchers measure penis length themselves using a standardized technique. Despite this lack of standardization, it’s worth noting that the available self-reported data concludes 7-inch penises to be larger than average in size.

In this article, learn how 7 inches compares to the average penis length, along with potential challenges of having a larger-than-average dick. Then, get some tips for making sex more comfortable for your partner, no matter how big you are.

According to available research, having a 7-inch penis likely puts you an inch or more over average. But, what constitutes “average” in the first place varies widely between studies. That’s because the findings often rely on self-reported (read: hard-to-trust) data.

For a 2020 review of studies published in the Journal of Sex & Marital Therapy, researchers measured penis size (rather than relying on participants to measure themselves. (For reference, the results of reviews are often considered more reliable than the results of individual studies since they use a larger combined sample size and show that results are replicable in different groups.)

The researchers of the review found that the average length of a stretched flaccid penis among 21 studies was 5.11 inches. The average among 10 studies where researchers took measurements of erect penises was 5.36 inches. Stretched length is generally considered equivalent to erect penis length and is easier to measure in a research setting.

The researchers concluded that the average penis size is likely between 5.1 and 5.5 inches. In accounting for volunteer bias (you’d probably be more willing to volunteer if you feel good about your penis size, that is), they note the actual average likely at the lower end of the range.

Another big analysis published in the World Journal of Men’s Health in 2023 examined 75 studies conducted over 79 years, involving more than 55,000 men total. Researchers found the average erect penis length to be 5.5 inches. Based on these results, they concluded that the typical penis length falls around 5.5 inches.

Penis Size Percentiles: How Average-Size Erect Penises Stack Up

In a 2021 study using data from 800 men in Argentina, researchers estimated penis size percentiles.

The researchers reported the following percentiles for stretch penis length:

Again, it’s worth noting that men who volunteer for studies focused on penis length may not accurately represent the population as a whole. It’s plausible that men with larger penises are more likely to sign up for studies related to penis size.

Average Penis Circumference

The results of studies examining average penis circumference (girth), are also questionably reliable and have a wide range of results based on factors such as:

• Self-reported versus measured size

• Self-measured versus researcher-measured data

In a 2015 study, researchers measured the erect penis circumference of 381 participants and found an average of 11.7 centimeters, or 4.6 inches. People excluded from the study included those with:

• Congenital or acquired penile abnormalities

• Previous surgery

• Complaints of small penis size

• Erectile dysfunction (ED)

Given the limitations of the sample size, it’s a fair conclusion to say the reported average isn’t necessarily reflective of the general population.

The Link Between Penis Size and Erectile Dysfunction

Penis size and ED aren’t known to be related. ED can affect men with a penis length smaller or larger than average. Some of the established risk factors of ED include:

• High blood pressure

• High cholesterol

• Diabetes

• Clinically low testosterone levels

• Obesity

• Smoking

• High alcohol consumption

• Benign prostatic hyperplasia (BPH) with lower urinary symptoms

• Depression

Erectile dysfunction is often associated with premature ejaculation, as both conditions frequently coexist. PDE5 inhibitors such as Viagra® (sildenafil) or Cialis® (tadalafil) are often the first-line treatment options for erectile dysfunction.

Having a penis on the larger size is often considered a positive, but it may have psychological impacts that are positive, neutral, or negative.

Confidence and Self-Esteem

For some men, having a 7-inch penis can enhance their confidence and self-esteem, as societal norms often associate larger sizes with desirability.

However, others may feel uncomfortable or objectified by the focus on this one particular part of their body, leading to insecurities or performance anxiety.

Body Dysmorphia

Body dysmorphic disorder (BDD) is a mental health condition where a person becomes excessively focused on a perceived flaw in their appearance, leading to significant distress. When this preoccupation specifically involves concerns about the penis, it's referred to as penile dysmorphic disorder, or more informally, "small-penis syndrome."

Studies consistently conclude that many men are dissatisfied with their penis size, and it’s not just those who fall on the smaller-than-average range. Even men with average or larger sizes often struggle with concerns about their penis, with many who seek penis enlargement surgery falling into this category.

A small 2022 study looked at 37 men seeking consultation for penis enlargement surgery. The findings revealed that a notable portion of these men exhibited signs of body dysmorphic disorder.

The following are prevalent myths about penis size.

Bigger Is Always Better

Particularly if they perceive their penis to be small, some men may see it as a limiting factor in their sexual ability or sex life. But, sexual satisfaction is not solely dependent on penis size. Communication, technique, and emotional connection play essential roles in achieving satisfaction for both partners.

In a 2015 study, researchers examined the penis preferences of 75 women on a university campus using 3-D penis models. The women reported an average length preference of 6.4 inches for one-time sexual partners and 6.3 inches for partners in long-term relationships. It's important to note that these figures represent averages, meaning some women preferred sizes smaller than these measurements, while others favored larger ones. Some research also suggests penis girth plays a larger role in providing sexual satisfaction for females.

In the same 2015 study, the preferred girth measurements were 5 inches and 4.8 inches, respectively, for one-time sexual encounters and long-term partners.

There’s little research available examining the preference of men who have sex with men.

Other factors that likely play a large role in determining sexual satisfaction include:

• Sexual techniques

• Intimacy and emotional connection

• Communication

• Adequate foreplay

Penis Size Impacts Fertility

Genital size has no impact on fertility. The ability to have a child is primarily related to factors such as your sperm quality and other factors unrelated to size of the penis.

The only exception is in cases of very small penis size, such as micropenis. It's important to note that while "micropenis" is often casually used to describe a small penis, it is actually a medical term for a penis that is significantly smaller than average, typically due to a deficiency in male sex hormones during early development.

Micropenis is sometimes associated with conditions such as Klinefelter syndrome, which may affect fertility.

A Bigger Penis Makes You More Masculine

There are also misconceptions that a larger penis size correlates to higher degrees of masculinity, and some men falsely correlate their penis size as a marker of their worth as a man. Although the hormone testosterone plays an important role in the development of the penis in childhood, research doesn’t support the claim that adult men with higher testosterone levels have longer penises.

So, Does Penis Size Matter at All?

Penis size might matter for some partners but not for others. A larger penis may feel more pleasurable to certain partners while others might find they can better accommodate a smaller penis.

Other forms of sex, such as oral sex, may also be easier than penetrative sex if your partner has trouble with your size. Many sex toys are available that may help mix up your sex life for you and your partner, particularly if they’re concerned about your size. So essentially, whether or not 7 inches is “good” depends on whom you ask.

There’s no standardized way to correctly measure the size of your penis. Some people measure from the top of their pubic bone to the tip of their penis while others measure from the base. Some people may compress the fat over their pubic bone while others don’t.

This lack of standardization is part of the reason why studies report such widely varying averages. Many studies use stretched flaccid penis length rather than erect length since stretched length doesn’t require a study participant to have an erection.

In one study from Italy, where self-measured penis dimensions were recorded, the researchers instructed the men to use a tape measure on their penis and report the length from the end of the tip of the penis (glans) to the pubic bone with the fat depressed.

With a larger-than-average penis, certain sexual positions, particularly those that are deeply penetrating, may be uncomfortable for your partner. For example, many people find that doggy style causes the penis to penetrate deeper during vaginal sex than missionary style does.

You can potentially help make intercourse more pleasurable for your partner by ensuring that you spend adequate time on foreplay and use a high-quality lubricant such as our Glide Water-Based Lube.

A 7-inch penis is likely above average in length, although most of the available data on average penis size is likely unreliable due to participant bias. There’s no evidence that penis size is related to your fertility, orgasm strength, or overall sexual health.

Although having a large penis is often seen as a positive, it can come with some challenges such as making partnered sex challenging, especially when adequate time isn’t spent on foreplay.

Here are some ways to support your sexual health if your penis is larger than average.

• Choose the right condom: Men with a larger penis size may also have to take more care that their condoms can fit their extra girth or length. Buying condoms that are too small can put you at risk of them breaking during intercourse. (Learn more about condom sizing here.)

• Communicate with your partner: Your partner can let you know if there’s anything you can do to make sex more enjoyable for them.

• Talk to an expert: If you’re concerned about your size, you can visit your healthcare provider or a sexual health expert called a sexologist.
