Penis Size by Age: The Chart Every Man Should See

How Your Penis Size Evolves Through the Years — and Why It Matters

How does penis size change as men age? Is there such a thing as growth after puberty — or shrinkage with age? If you’ve ever wondered how your size stacks up against other men in your age group, you’re not alone. Millions search for the answer every year.

This guide breaks down real data, from teenage years to your 60s and beyond, in one simple penis size by age chart. You’ll discover what’s average, what affects growth or loss, and how to improve your size, thickness, and confidence naturally.

How Penis Size Is Measured (The Right Way)

To compare sizes accurately, standard measurement rules apply:

• Measure from the pubic bone to the tip (press through fat)
• Take readings while fully erect
• Use a flexible measuring tape
• Repeat 2–3 times and average your result

Now let’s explore the chart data by age.

Penis Size by Age Chart

Age Range	Average Erect Length	Average Girth
13–17	4.5 – 5.7 in	4.2 – 4.5 in
18–24	5.1 – 5.9 in	4.4 – 4.9 in
25–34	5.2 – 6.0 in	4.5 – 5.0 in
35–44	5.1 – 5.8 in	4.4 – 4.9 in
45–54	5.0 – 5.7 in	4.3 – 4.8 in
55–64	4.8 – 5.5 in	4.2 – 4.6 in
65+	4.6 – 5.3 in	4.1 – 4.5 in

Why Size May Decline With Age

As testosterone levels drop and blood circulation weakens with age, some men notice slight reductions in size. This isn’t just about tissue loss — it’s about elasticity, blood volume, and erection quality. Fortunately, this decline isn’t irreversible.

Factors That Influence Penis Size Over Time

• Hormonal health (testosterone, growth hormone)
• Weight gain (fat pad hides visible length)
• Smoking or alcohol (reduces blood flow)
• Lack of sexual activity or stimulation
• Stress, cortisol, and inflammation

How to Prevent (or Reverse) Shrinkage

Here’s how to fight back naturally:

• Lose belly fat to expose more base length
• Train pelvic muscles (Kegels) to boost erection power
• Improve circulation with cardio and supplements (L-arginine, beets)
• Use jelqing and stretching exercises 3–4x per week

Does Penis Size Increase After 18?

In most cases, no. However, for some late bloomers or men who improve blood flow and stretch ligaments, gains are possible. Even if growth is minimal, improved hardness, girth and control can make you feel (and look) significantly bigger.

How to Grow and Maintain Your Size Naturally

Follow this proven growth strategy:

1. Use warm compresses before sessions to relax tissue

3. Train stamina and PC muscles for longer sessions
4. Eat nitric oxide boosters and stay hydrated

Optimize for Your Age — Not Against It

Regardless of your age, you can optimize your sexual health. The key is consistency. Men in their 50s and 60s have reported better size, performance and erections after just 30 days of training with the right plan.

Girth Gains vs Length Gains: What’s Easier to Improve?

Girth is often easier to improve than length. Why? Because girth is related to blood capacity and tissue expansion, while length involves stretching ligaments and overcoming genetic structure. Many men report visible girth increases after consistent jelqing and squeeze-based routines.

Increased girth can enhance sensation for your partner and make erections feel more powerful. It’s also the part women tend to notice more during intercourse.

Visual Changes Don’t Always Mean Growth

You may look bigger just by improving blood flow, achieving fuller erections, and reducing your fat pad. Even without permanent length increase, these changes can dramatically boost visual size and sexual confidence. Before and after photos in our community often reflect this kind of progress.

What Women Think About Penis Size by Age

Surveys indicate that most women don’t focus on age when considering size. Instead, they care about how a man uses what he has. In fact, some older men report better sexual success because of increased emotional intelligence and stamina — not size alone.

What Age Do Men Reach Full Penis Size?

Most men complete their penis growth between ages 16 and 21. However, lifestyle factors like hormone levels, activity, and nutrition during puberty can influence final size. Late bloomers may continue growing slowly into their early 20s, but dramatic changes after 25 are rare without intervention.

Why Comparing Is Risky for Confidence

Charts are useful for data — not self-worth. Every man’s body is unique. What matters more than how you compare is how you perform, how confident you feel, and how well you please your partner. Comparison can motivate or destroy — use it wisely.

How Porn Misrepresents “Normal”

In adult media, actors are selected for size. This creates the illusion that 8+ inches is standard, when in reality, it’s rare. This distortion affects young viewers the most, creating insecurities and false standards early in life. Knowing the real data (like this chart) helps reset your expectations to something healthier — and more accurate.

Why Some Men Seem to “Shrink” Over Time

It’s not always actual shrinkage. Weight gain adds fat around the base, making the penis look smaller. Loss of erections due to poor health or low testosterone also reduces fullness and length perception. These issues are reversible with discipline and the right routine.

Intermittent Fasting and Penis Size?

Some men in biohacking communities report stronger, fuller erections and improved size perception after practicing intermittent fasting. Why? Because fasting lowers inflammation, balances hormones, and improves blood circulation — all critical factors for sexual performance.

Advanced Tools That Can Help

• Penis pumps: Temporary expansion and vascular training
• Traction devices: Help lengthening through constant stretching
• Infrared heat wraps: Improve elasticity and blood flow
• Growth-focused supplements: L-citrulline, zinc, magnesium

Tools can support your goals — but only when paired with consistent practice and recovery.

Track Your Progress Over Time

Just like the gym, progress requires tracking. Keep a measurement journal, note your morning wood strength, and document perceived visual changes. Monthly pictures (for your own eyes only) can show growth you didn’t notice daily. Focus on progress, not perfection.

Compare Charts Without Losing Perspective

Use this chart to inspire discipline — not shame. Your current numbers don’t define your future performance. With the right strategy, consistency, and mindset, men in any age group can improve size, stamina, and satisfaction.

Real Stories from Men Who Improved After 40

Marco, 52, thought his sex life was over. After starting a plan with beets, kegels, and stretching, he reported “the hardest erections of his life” in under 6 weeks. These aren’t rare cases — they’re results from consistency.

Pro Tips from the Supremepenis.com Method

Whether you’re 25 or 65, you can build size, stamina, and satisfaction — naturally. The tools are real. The method is proven. The rest is up to you.

Penis Size and Overall Masculine Identity

For many men, penis size becomes a psychological representation of masculinity. It can influence self-esteem, confidence, and even assertiveness in daily life. But here’s the truth — size alone doesn’t define your masculine power. Action, presence, responsibility, and performance are what truly matter.

The Silent Epidemic: Size Insecurity Among Men

Even men with above-average size can struggle with insecurity due to porn, media, or past experiences. Size insecurity can lead to avoidance of intimacy, performance anxiety, or overcompensation in other areas. Opening up, training consistently, and gaining control over your body help break this silent shame cycle.

Building Confidence Regardless of Size

Confidence comes from competence. The more you learn about your body, your partner’s desires, and techniques that work, the more self-assured you become — regardless of size. Small daily victories in training, nutrition, and communication build long-term dominance in the bedroom.

Why Women Care More About Connection Than Size

When surveyed anonymously, women consistently rate connection, communication, and emotional safety higher than size. The truth is, most women remember how you made them feel — not how many inches you were. And that’s where your power lies.

Celebrate Your Progress

Stop waiting for perfection. Celebrate the fact that you’re here, reading, learning, and taking action. Most men never do. You’re already ahead of the game. Stay consistent, track results, and focus on becoming the most confident, controlled, and aware lover she’s ever had.

Your Journey Starts Now

This isn’t just about inches — it’s about evolution. When you commit to mastering your body and mind, everything changes. And the results extend far beyond the bedroom.

2 Surprising Scientific Facts About Penis Size

• Fact #1: Men with higher cardio fitness have up to 30% better erection quality, regardless of age or size. That’s right — better blood flow = stronger performance.
• Fact #2: Cold weather can cause temporary penis shrinkage of up to 1 inch. This is completely normal and not related to your real size.

Final Words: Focus on Growth That Matters

Remember — your value isn’t defined by where you are on a chart. It’s about how far you’re willing to go. Real men don’t chase perfection — they chase progress. Your size, stamina, and satisfaction can all be trained, starting now.
