If you’ve ever worried about having a thin penis, you’re certainly not alone. Most men want to know how their penis compares to the average person.

If you’ve ever thought about how your penis compares in size to others in terms of thickness, you’re not alone. Most men want to know how their penis compares to the average person. Unfortunately, common curiosity may occasionally lead to fixation and worry regarding penis size. This can become an unhealthy and unneeded preoccupation, mainly because most men who believe their penises are too little have completely normal-sized penises.

When is penis size too small??

What is the typical size? Here are some significant findings from research conducted throughout the world, according to Medical News Today:

  • Up to 45 percent of men feel they have a tiny penis.
  • When flaccid, the average length was 7 to 10 cm (2.8 to 3.9 inches).
  • When flaccid, circumference/girth was between 9 and 10 cm (3.5 and 3.9 inches).
  • The average length when standing was between 12 and 16 cm (4.7 to 6.3 inches).
  • The average circumference was around 12 cm with an erection (4.7 inches).

What is a ‘normal’ or average penis size?

It’s not nearly the size many people believe!

According to the British Journal of Urology International, a flaccid penis has a girth of 9.31 cm (3.66 inches) while erect has a girth of 11.66 cm (4.59 inches). When volunteer bias is taken into account, the researchers feel that the average falls closer to the lower end of that range.

According to an older study, the average flaccid length is 3.61 inches.

Why is my penis skinny?

What is considered too small? What is too large? According to research, many men want a bigger penis, regardless of whether they believe their penis size is typical or not. Furthermore, some men assume they have a small penis when it is within the normal range. However, whether or not your penis is too skinny or not is another question men ask, even if they are confident it may be thick enough.


A micropenis is usually detected before birth. Inconsistent hormone levels throughout the third trimester of pregnancy might cause the disease.

When erect, an adult penis is unusually tiny if it is less than three inches (approximately eight cm) in length. Doctors have no assessment for thickness and a micropenis diagnosis.


Weight can cause substantial penis shrinkage. While weight has little effect on thickness, it can change perceptions on whether or not you are too thick or too thin. For every 30-50 pounds lost, men might increase 1 inch in penile length. The fat buildup will cause the penis to shrink. In addition, increased fat can also lead to a change in shape and even reduce overall health, penetration ability, and sexual performance. Losing weight can answer many of your size concerns. However, if you are already thin, you will see little results.

Age and Erectile Dysfunction

Men generate less testosterone as they age, leading to a decrease in libido and penis size. Aging also causes fatty deposits to accumulate in the arteries, decreasing blood flow to the penis, limiting girth. As a result, the muscle cells in the erectile tubes of the penis weaken.

Blood flow

A man may be unable to obtain, retain, or get hard enough for penetration if insufficient blood flows to and remains in the organ during sexual activity. All of these difficulties may be addressed if blood vessels supply is improved. Lack of blood flow can prevent a penis from reaching full thickness.

How to measure a penis

Measuring a penis can be helpful for more than one reason. Knowing proper girth and length can help select the appropriate size condom, for example. To properly measure. press a measuring tape into the groin and measure from the base of the penis to the tip to determine penile length.

To measure penis thickness, wrap a measuring tape around the widest section of the penis.

How to measure an erect penis’ girth

Wrap the thread or tape around the thickest section of the shaft of your penis. Mark where the string joins and measure the string distance using a ruler if you’re using string. If you’re using a flexible measuring tape, record the measurement when it reaches your penis.

What size penis do women want?

According to studies based on 3-d models, here is what women want:

For one-night stands, the average size is length = 6.4 inches/16.3 cm, circumference = 5.0 inches/12.7 cm. For long -term relationships women prefer length = 6.3 inches/16.0 cm, circumference = 4.8 inches/12.2 cm. For overall sexual partners, women preferred a penis with a somewhat greater circumference and length. According to these first estimations of erect penis size preferences based on 3D models, women properly recall size and prefer penises that are just a little bigger than average.

However, many women say they prefer overall performance for their sexual health. Women leading a fulfilling sex life have had multiple sexual partners and develop more pleasure out of the overall sexual performance in their sex life, with size as one factor of sexual activity satisfaction.

What about Gay Men?

According to The Gay Men’s Health Project’s studies, anxiety and concerns about penis size influence the sex gay men have and can prevent a fulfilling sex life for many men. Sexual positions such as whether oral sex or anal sex are preferred and even how sexually active one is are factors. In a study of 566 homosexual and bisexual males, 38% stated their penis size creates worry, 16% said they’d received negative comments about it, and 22% said they’d rejected sex in the past because of it.

When to seek penis enlargement?

Hormone therapy, surgery, and other methods can enhance the size of a small penis. However, these therapies are risky, and most people do not have a small enough penis to merit such action.

Doctors normally do not prescribe therapy unless a penis has a length of less than 4 cm (1.6 in) or an erect length of less than 7.5 cm (3 in). Physicians seldom recommend surgery to correct thinness alone.

The motive for seeking therapy is often based on self-image, worries of inadequacy, a desire to impress others, and other psychological variables.

Once consumers learn the hazards and potential treatment consequences, many people abandon the concept of penile enlargement surgery.

How to Increase Your Penis Size

Many popular penis-enlargement treatments have limited results, and some might even cause lasting penile injury or even penis shrinkage! Here are a few of the more popular items and techniques:

  • Exercises These exercises, also known as jelqing, involve a hand-over-hand movement to pump blood from the base of the penis to the top of the penis. Although the procedure looks safer than other treatments, there is no scientific evidence that it works, resulting in scarring, discomfort, and deformity.
  • Lotions and pills These often include minerals, herbs, vitamins, or hormones that the producer claims will expand the penis. None of the items or pills have been proven effective, and some may even be hazardous.
  • Vacuum pumps Pumps are occasionally used to treat erectile dysfunction because they suck blood into the penis, causing it to enlarge. A vacuum pump can briefly make a penis appear bigger. However, using one too frequently or for too long might damage the elastic tissue of the penis, resulting in less hard erections, leaving you thinner overall when it matters. In addition, the effect is temporary. Wearing off leads to penis shrink effects.
  • Stretching Stretching is a penile augmentation process of applying mild stress to the penis via a stretcher or extender device, commonly known as a penile traction device. A few modest studies have found that these devices can increase lengths by half of an inch to almost 2 inches (approximately 1 to 3 cm). However, stretching will make you thinner, defeating your performance goal.

To prove safety and efficacy, more extensive research is required for many of these treatments.

Surgery is dangerous and may not be effective

Studies of existing surgical procedures to extend the penis have yielded mixed safety, efficacy, and patient satisfaction. Considering the treatment costs of surgery, this is not the most optimal option.

Enlargement surgeries, such as dividing the suspensory ligament, may add roughly half an inch (1.25 centimeter) to the look of a flaccid penis but do not affect its actual length. In the worst-case scenario, surgery can lead to consequences such as scarring or infection, and loss of feeling or function.

A physician performs no commonly used surgical procedures to increase thickness.

Impact of obesity and age and erectile dysfunction


Compared to normal-weight males, penile length development is markedly reduced (by roughly 10%) in obese boys, with concomitantly lower testosterone levels, across pubertal periods. Childhood obesity is a significant predictor of decreased testosterone levels and penis growth. In addition, fat buildup even in adults can lead to the appearance of penis shrinkage. If you are overweight, talk to your doctor about a healthy diet to help stop penis shrinkage.


As men age, they generate less testosterone, leading to a decrease in libido and penis shrinkage. Aging also causes fatty deposits to accumulate in the arteries, decreasing blood flow to the penis. As a result, the muscle cells in the erectile tubes of the penis weaken.

Erectile dysfunction

Compared to individuals with normal erections, severe ED patients refractory to penile injection had smaller penile. The current study stratifies distinct ED ratings in a more homogeneous group of healthy males and found no link between objective penile size and ED diagnosis. However, lack of blood to blood vessels does affect erection size. 

There are many causes of erectile dysfunction, including mood, health, diet, alcohol consumption, and hormonal imbalance.


Can masturbation affect penis thickness?

Masturbation has no long-term effect on penis growth, according to scientific studies. Masturbation causes an erection that expands a thin penis, although momentary. After ejaculation, you will experience penis shrinkage back to normal size.

Does penis thickness affect orgasm?

That answer is not so straightforward. While the shape and erection firmness can affect orgasm, too much girth can cause pain after penetration.

Penis thickness diagnosis

There is no official doctor diagnosis of a thin penis, but other issues can cause a change in thickness, such as Peyronie’s disease, which can also cause erections to curve to the right or left side change the shape of the penis.

Can sex toys increase penis thickness?

There is no evidence that sex toys can substantially affect penis thickness beyond temporary blood vessels being dilated from increased stimulation during an erection.


Despite common anxieties, most men have penises that fall within the normal size range. Focusing on overall sexual performance and communication with your partner is likely more important for a satisfying sex life than penis size.

If you’re still concerned about your penis size or have questions about erectile dysfunction, consult a healthcare professional. They can address your specific situation and offer guidance. Remember, you’re not alone in your concerns, and there’s help available.
