What is the average penis length?

At Fellos.nl, we want to help men be more informed and confident about their bodies. Penis size is a hot topic that can often lead to uncertainty and misunderstanding among men.

According to various scientific studies, the average length of an erect penis is between 13 and 15 centimeters. However, the average length of a flaccid penis varies more, usually between 7 and 10 centimeters. It is important to understand that there is a wide variation and that all sizes are normal.

How is penis length measured?

Penis length is usually measured in two ways:

  1. In a flaccid state: Measure the penis from the base near the pubic bone to the tip of the glans without stretching.
  2. In an erect state: Measure the penis from the base of the pubic bone to the tip of the glans when it is fully erect.

Factors that may affect penis length

There are several factors that can affect the length of the penis:

  • Genetics: This plays the biggest role in determining size.
  • Age: The length may vary slightly with age.
  • Temperature: The size of a flaccid penis may vary depending on the temperature
  • Health: Conditions such as obesity can reduce apparent height due to extra fat tissue around the base of the penis.

Penis length concerns?

It's not uncommon for men to worry about the size of their penis, but it's important to know that these concerns are often overstated. Most sex partners say that other aspects of sex are more important than penis size. Good communication, mutual respect, and emotional connection play a much larger role in a satisfying sexual relationship.

What if you're still worried?

If you're concerned about your penis length, it's important to remember that variation is normal. However, should you feel persistent uncertainty affecting your self-esteem or relationships, consider talking to a sexologist. A doctor or therapist can help you discuss these concerns and address any underlying issues.

Average penis length varies and there is a wide range of what is considered normal. It's important to know that penis length is only one aspect of male sexuality and does not determine your value as a person or (sex) partner.
