Do I Have a Micropenis ? How to Measure Your Penis Properly

I was having a look at my web-stats the other day and noticed that many people discover the site using search queries like "Do I have a small penis ?" or "Do I have a micropenis". So, I decided to make this guide to show you the proper way to measure your penis to find whether you have a micro, small, average or big penis.

First, I want to mention that micropenis is a term strictly referring to a penis with a very small erectile length. This means that you only have to measure your length to see if have a micropenis. Still, I have decided to include instructions on how to measure your girth as well. Let's begin:

How to measure penile length
The first thing you should have in mind is that all measurements must be taken while standing.

Begin by getting yourself a strong erection. Use porn, imagination, or whatever works best for you. Then hold your penis parallel to the floor. Take a ruler and press it gently against your abdomen as shown in the picture below. Press relatively hard, as some of the fat "hides" a part of your penis. This is especially true for larger people.

The size of the erection isn't always the same and depends on some factors, including:
  • Time of day
  • Room temperature
  • How aroused you are

For this reason, you should ideally measure yourself 3 times a day (morning, noon, evening) for three consecutive days. Then sum all the numbers up and divide them by nine, which in turn will give you, your average penile length.

Tip: Pressing hard into the pubic fat is justified by the fact that some men have more fat and pubic hair then other. Furthermore, during intercourse the "hidden" part of the penis can also go in depending on position and how deep you thrust. An easy way to make your penis appear larger is to simply lose weight or have liposuction in that area! Shaving also helps, especially if you have a really large bush!

Analyzing your findings
By now, you probably wonder whether you have a micropenis and where you stand compared to the rest of the male population. Please note that we can't give a definite answer to this, as we must first take certain factors under consideration.

For example, age is an important factor since teenagers have a smaller - on average - penis than adults. As covered in our "what is a micropenis" article, another factor is ethnicity, as black people tend to have a slightly larger penis than Caucasians do, while Caucasians have a larger penis compared to people of Asian origin. Additionally, different studies report different results in regards to average penile length.

Generally speaking, if you are an adult:
  • You probably have a micropenis if your penis is less than 9 cm (~3.5 inches)
  • You have a small penis, but within the normal range, if you are anywhere between 9 to 12 cm (3.5 to 4.7 inches)
  • Any penis between 12 to 16 cm (4.7 to 6.2 inches) is considered to be a normally sized penis
  • Consider yourself to be lucky if your penis is 16-20 cm (6.2 to 7.8 inches). You are above average!
  • Even bigger ? Congratulations, you meet all the qualifications to become a successful male pornstar !

How to measure your penile girth
As promised, I will also cover the proper way to take girth measurements. For girth, things are a bit more complicated.

As before, you will need to be standing and to have a strong erection. Next, take a a measuring tape and take three measurements, one just below the glans, one in the shaft's middle and one at the base, as shown in the picture below:

For reliable results, you must again take three measurements (morning, noon, evening) for three consecutive days. Now, add your bottom, middle and top measurements individually and divide each of the three sums by 9. This way you will get your:
  • Average "bottom" girth
  • Average "middle" girth
  • Average "below the glans" girth
Finally, you can add these three numbers and divide them by three to get your overall mean penile girth.

Analyzing your girth
Currently, there is only one reliable clinical study (I think) on penile girth, putting it somewhere between 12 to 13 cm. If you know of any other reliable studies please let me know in the comments

My penis is small, I want a bigger one !
You are not alone. Most guys wish they had a bigger penis! At the moment, there are only two clinically approved methods (e.g. surgery) to enlarge your penis. Please visit the penis enlargement section of the site where I explore them in more detail! You may also want to have a look at another article of mine, does penis size really matter?

Don't hesitate to leave a comment if you got any questions!


  1. My penis is 3cm erect and non exsist when flaccid according to what I have read it's about the size of a new born baby

    1. Well that's unfortunate.

  2. My penis soft (flaccid) is 7,5 cm and erect 13,5 cm. Is normal? I'm 50 years old and I'm complexed.

  3. my penis is just under 6" length which is normal sized in legnth but i only have around 3" girth. what is the normal girth size in inches.

  4. You are correct about the effect of temperature on size. When cold my penis retracts and it is difficult to get any measurement. My testicles are always tight, but cold they are so tight and pulled up that I get freaked out thinking they are going into my abdomen and never come back down.
    I don't think I will ever really be comfortable with that.

  5. I've just turned 15 and my penis is around 10-11 cm when erect, 6cm when flaccid. Is this normal?
