Whether it's to figure out what size condoms to buy or just out of curiosity, most men have attempted to measure their penises at some point. And while there are many myths about shoe size, hand size, or the tip of the index finger to the tip of the thumb, there is actually a correct way to go about it. In this article, we have all the information you need to correctly measure the length, width and girth of the penis.
Does penis size matter?
Learning how to measure your penis is essential for different reasons. And no, not because women care (in fact, studies indicate that about 77% of women don't care about your height). However, your results will impact which condoms you should buy.
If you don't wear the right size condom, you may encounter undesirable scenarios. If it's too tight, you may find it hard to put the condom on and you'll probably feel uncomfortable. But if the condom is too wide, it may tear or fall off. Both of these scenarios increase your likelihood of having unprotected sex, which could lead to STIs or unwanted pregnancy.
How to correctly measure penis length
First of all, you need to have materials. It is best to use a soft tape measure, such as those found in sewing kits. A ruler could also work, although it doesn't give quite the same level of precision, especially if your penis is curved. A retractable tape measure is definitely not recommended, it can snap into place quickly which could lead to an uncomfortable injury.
Once you have your measuring tool, we can move on to measuring! Depending on why you are doing this, you can rate your penis size as either flaccid or erect. If you are measuring condom size, make sure you are fully erect.
Length is probably the easiest measurement to take. All you have to do is measure the distance from the very base of your penis to the tip of your glans. It is common to measure the top side rather than the bottom or in the sides.
Place the end of your tape measure at the tip of the penis and measure along the penis to the pubic bone. If you have a layer of abdominal fat covering your pubic bone, you can gently press on it with your hand for a more accurate measurement.
How to measure circumference
Once you have your length measurement, you can also determine your circumference.
To do this, simply wrap your soft tape measure around the widest part of the penis. Depending on your penis, this could be the shaft of your penis or the glans. Then just note the measurement where the tape meets.
How to measure penis width
Sometimes condom brands size their products based on the width (diameter) of your penis. It's rare, but luckily it's easy to calculate. Once you have the circumference, all you have to do is divide it by pi, which is 3.14. For example, if your circumference is 11 centimeters, your width is 3.5 cm.
So what is normal?
Like all parts of the body, penises come in different shapes and sizes. Even so, it's natural to want to know how you stack up against other men.
The 2014 research from Kings College London brought together 17 studies, representing a total of 15,521 men measured by healthcare professionals. The study excluded men with a penile abnormality, previous surgery, or who had previously complained of short stature.
Researchers have found that the average erect penis length is 13.12 centimeters. The average erect circumference was 11.66 centimeters.
Use your measurements to buy condoms
Popular condom brands offer the following size guide:
Small/Slim; if your circumference is between 8.5 and 10.5 centimeters, it is recommended to look for a condom advertised as narrower, small, thin or fitted. Classic/Regular/Standard; if your circumference is between 10.5 and 12.5 centimeters, standard condoms will probably be fine for you. Large/XL; if your circumference is between 12.5 and 14.5 centimeters, look for condoms labeled larger, wide or XL.
While these brands use girth as a size guide, other brands may use length, width, or a combination of measurements. Before buying condoms, you can read the packaging, which should give an indication of the size it fits.
