Is It Normal To Have A Small Penis?

is it normal to have a small penis?

What is too small? What is too big? Research suggests that many men desire a bigger penis regardless of whether they think their penis size is average or not. And, some men believe they have a small penis when it is actually within the average range. In this blog we will look at the science behind the average penis size, how to measure your penis and the conditions that can cause a it to be or seem smaller than usual.


What is Average?

The average length of a penis is roughly 3.6 inches flaccid and 5.2 inches erect. But how did this become the number?


Research on Penis Size

There have been several studies over the years that have attempted to give a definite number for the average penis size. One smaller 2014 study in the Journal of Sexual Medicine looked at the average penis size in 1.661 men. The researchers found that the average erect length and circumference of participants was 5.6 inches and 4.8 inches, respectively.


Another larger study from 2014 compiled data from over 15,000 men to determine average size. In this study, length and circumference measurements were taken both flaccid and erect. The results determined the average penis length to be 3.6 inches while flaccid and 5.2 inches while erect. In addition, the average penis circumference was measured as 3.7 inches while flaccid and 4.6 inches.


It’s important to note that the first study used self reported measurements, while the second study used measurements taken by a health professional. Both studies have their limitations, but the numbers reported are consistent with similar studies on average penis size.



Keep in mind that sizes of “small” and “large” are comparative and that averaging penis size is based on what is known. Known measurements, even a substantial study where more than 15,000 men were measured, are based on groups. The United Nations reported the world’s male population to be at about 3.9 billion in 2019. That means that 15,000 men is only about 0.0004 percent of the world’s male population.


Collectively, average measurements from similar studies set a good average and are important to have, but there is always more to know.


How to Measure Your Penis

Lastly, if you are curious about how to measure the size of your penis, here is a correct way to get an accurate measurement:


  1. You will need to have either a tape measure or ruler on hand.
  2. To measure the length, start your measurement at the base of the penis, where the penis meets the pubi bone.
  3. Run the ruler or tape measure along the full length from the base to the tip. Do not measure excess foreskin length.
  4. To measure the girth, wrap a flexible tape measure around the shaft of the penis at the base or around the midpoint between the base and head.
  5. If you are measuring your penis flaccid, be careful not to pull or stretch it as this can potentially cause injury.
