Facts about penis size

If you’ve ever wondered about your penis size, you’re not alone. It’s one of those things a lot of guys think about but don’t always feel comfortable talking about.

So let’s dive into the facts, look at some averages from around the world, discuss rare conditions like micropenis, and show you how to measure yourself properly — because, let’s face it, we all want to get the details right.

What’s the Average Penis Size?

Let’s start with the big question: What’s “normal”? Turns out, penis size varies a lot around the world. Based on large-scale studies (yes, they’ve done a lot of measuring!), here’s a breakdown of averages from different regions:

Flaccid Length

  • Global Average: Around 3.6 inches (9.16 cm)

  • United States: About 3.6 inches (9.2 cm)

  • Europe: 3.5–3.7 inches (8.9–9.4 cm)

  • Africa: 3.7–4.1 inches (9.4–10.4 cm)

  • Asia (East and Southeast): 3.1–3.4 inches (7.9–8.6 cm)

Erect Length

  • Global Average: 5.16 inches (13.12 cm)

  • United States: About 5.16 inches (13.12 cm)

  • Europe: 5.1–5.5 inches (13–14 cm)

  • Africa: 5.7–6.3 inches (14.5–16 cm)

  • Asia (East and Southeast): 4.3–4.7 inches (10.9–11.9 cm)

So, if you’ve ever compared yourself and thought, “Am I normal?” chances are, you’re well within the typical range. Penis size doesn’t change your worth or your sexual ability — it’s just one part of who you are.

Let’s be real — most of what we think about penis size comes from watching porn, which usually features guys with sizes that are way above average. This gives a totally skewed view of what’s “normal” and can leave a lot of us feeling insecure for no reason.

In reality, most penises are much more modest in size. If you’re curious about what average really looks like, check out r/averagepenis on Reddit. It's a community where guys talk openly about their experiences, and you’ll see that what's shown in porn is far from the everyday norm.

Busting Penis Size Myths

There are plenty of myths out there when it comes to penis size. Here are some of the most common ones, busted:

  • Myth: “Bigger is always better.”

    • Reality: Not true! Studies show that communication, chemistry, and technique are much more important for sexual satisfaction than size.

  • Myth: “Foot or hand size equals penis size.”

    • Reality: Nope. There’s no scientific link between body parts like hands, feet, or nose and penis size.

  • Myth: “Losing weight will make my penis grow.”

    • Reality: Losing weight doesn’t change your actual penis size, but it might look bigger since there’s less fat around the base.

Rare Conditions: Micropenis and Macrophallus

While most guys fit within the average range, there are rare medical conditions that affect size, like micropenis and macrophallus.

Micropenis

Micropenis is defined as a penis that’s significantly smaller than the average, specifically less than 2.75 inches (7 cm) when erect. This condition is usually due to hormonal issues during development. While it’s rare, there are treatments, such as hormone therapy or surgery, for those who want to explore options.

If you’re curious about this or want to connect with others who might have similar experiences, there’s a whole community on Reddit at r/micropenis where people openly discuss their experiences, challenges, and support options.

Macrophallus

On the flip side, macrophallus refers to an abnormally large penis, though it’s not often a medical concern. Most men with larger-than-average penises live perfectly healthy lives, though it might come with its own set of challenges, too.
