What’s the average penis size? Probably smaller than you think
Many men experience anxiety about the size of their penis, wondering if it’s visually appealing or sufficient to satisfy their partner. Watching porn can give the impression that the average penis is 9 or 10 inches long, but this is far from reality. Although scientists can’t pinpoint an exact average, research suggests the typical erect penis measures between 5.1 and 5.5 inches. Some may be larger, some smaller, but if it works for you and your partner(s), it’s perfectly fine. Keep reading to discover more about what science says about average penis size.
Average penis length
A 2015 research review determined that the average erect penis measures about 5.17 inches (13.12 cm) in length, while the average flaccid penis is approximately 3.6 inches (9.16 cm) long. Some penises show significant growth when erect, leading to variations in the size difference between a soft and hard state.
So, why do many people believe the average penis is over 6 inches long? This misconception partly stems from inaccurate portrayals in porn and a 1960s report by Alfred Kinsey and his colleagues, which mistakenly suggested that the average penis size was over 6 inches. This overestimation has lingered in our collective mindset, but more recent and extensive research has shown that the true average is around 20% smaller than Kinsey’s findings.
Average penis girth
Penis girth, which refers to the circumference or thickness, is an often-discussed aspect of sexual health. On average, the circumference of an erect penis is about 4.84 inches (12.29 cm), while a flaccid penis typically has a girth of around 3.67 inches (9.31 cm).
How many people have penises that are 7 inch dick or more?
It’s very rare to have a penis that measures 7 inches or more when erect. Research shows that only about 1% of men have an erect penis between 7–8 inches long. Studies, including those by Kinsey, indicate that extremely large penises—over 7–8 inches—are uncommon. Specifically:
- 1% of penises are between 7–8 inches long.
- 0.6% (6 in 1000) measure 9 inches long.
- Just over 0.2% (2 in 1000) are longer than 9 inches.
Most penises fall within an inch of the average size, meaning nearly 90% are “normal-sized.”
What is a micropenis?
A micropenis is a condition where the penis is significantly smaller than average. Approximately 0.6% of people worldwide are born with a true micropenis. Healthcare providers diagnose a micropenis based on stretched penis length (SPL), with an SPL of 3.67 inches or less in adults being classified as a micropenis. While individuals with micropenises may feel dissatisfied with the appearance of their penis, their sexual function is generally normal.
Does penis size matter?
Worried about whether your penis size is enough to satisfy your partner? Rest assured, your partner likely isn’t as concerned about it as you are. In a survey of 170 heterosexual women, only 1% considered penis length “very important,” while 55% found it “unimportant,” and 22% rated it “very unimportant.”
Regardless of size, remember that pleasing your partner goes beyond penetration. Honest communication about likes and dislikes is essential for good sex.
How to measure your penis
Knowing your penis size and how to measure it accurately is crucial when selecting the right condom size. This is one of the few situations where size genuinely matters. A poorly fitting condom—whether too tight or too loose—can lead to performance issues like condom-associated erectile problems, difficulty ejaculating, or even increased risk of unwanted pregnancy and STDs.
To measure correctly, use a tape measure to determine both the length and girth of your erect penis. With these measurements, you can choose a condom that closely matches your size by checking different brands in-store or online.
How to make your penis bigger
While most people’s penises fall within a normal size range, many still feel dissatisfied and seek ways to make their penis bigger. This concern, especially if your penis is average-sized, may be linked to what researchers call penis anxiety or penis dysmorphic disorder (PDD), a form of body dysmorphic disorder.
For those with a micropenis, certain enlargement procedures or devices might offer some help. However, the reality is that if your penis allows you to enjoy a fulfilling sex life with yourself and your partner(s), it’s already the perfect size. If you have concerns about your sexual function or size, it’s best to consult with your healthcare provider.
