Did you know that over 60% of men still don’t know how to measure their penis correctly, or even what size it is? They often struggle to choose the right condom size because they’re unsure of their own measurements. Many are afraid to measure due to concerns about their size being too small, short, or misshapen, and fear being teased by friends.

Don’t worry, though, because Dr. Beer is an expert in enhancing penis size. Whether it’s through penile injections to increase girth, silicone injections for enlargement, or even surgery to lengthen and enlarge the penis, Dr. Beer can provide full-course treatments under the care of a professional surgeon.

A survey by the Ministry of Public Health found that the most common penis size among Thai men is 52 millimeters (based on condom purchases, not direct penis measurements). The most popular condom size sold in Thailand is 52mm, followed by 49mm, which accounts for nearly 80% of the market. Sizes like 54mm and 56mm are far less common.

For safe sex, you need to know your penis size to find the right condom. Don’t worry about whether it’s small or large because what really matters is technique and quality in bed.
When measuring, you want to know two things: 1) How long is it? 2) How thick is it? The thickness will determine the condom size since a condom that is too tight may break, and if you choose one that’s too big, it might slip off!

Let’s go over the correct way to measure your penis for the right condom size:
How to Measure Your Penis for the Right Condom Size

First, let’s clarify that you should only measure when your penis is fully erect! Measure around the middle of the length of your penis. You can use any method to get your penis erect, whatever you prefer. Dr. Beer has simplified three methods for measuring condom size:
- Using a Regular Measuring Tape The most accurate method to measure condom size is using a standard measuring tape, which can be bought at any store. First, wrap the measuring tape around the middle of your fully erect penis and record the measurement in millimeters (mm). Then, divide that number by 2.3 to get your ideal condom size.
Formula to Calculate Condom Size:
- The width of the condom (when flat) = The circumference of the condom (in mm) divided by 2
- The condom size you should use = The circumference of your penis (in mm) divided by 2.3
For example, if the circumference of your erect penis is 120mm, divide that by 2.3, which gives 52.17. So, you should buy a 52mm condom, as condoms can stretch a little and will fit comfortably without feeling too tight.
For most Asian men, the average penis size ranges from 49mm to 56mm in circumference, with Thai men commonly having sizes between 49mm and 52mm. Therefore, 49mm and 52mm condoms are the most common in Thailand.
- Using a Smartphone Yes, you read that right! You can use your smartphone to measure. Simply follow these steps:
- Open your browser and go to mysize-measure.com, and select English.
- Rotate your phone to landscape mode.
- Place your erect penis in the middle of the length on the measuring guide displayed on your screen to determine your size, then use that measurement to select your condom.

It’s also important to consider the condom packaging—check the FDA label, production date, and expiration date, and make sure to store the condoms properly away from heat, sunlight, and pressure.

Summary How to Measure Your Penis Correctly and Choose the Right Condom Size

For men whose penis is smaller than the sizes mentioned, don’t be discouraged. Women surveyed have confirmed that while size is important, other factors matter more, such as being a good partner in bed.
“Size matters, but knowing how to please her is even more important.” Simply put, having a larger penis doesn’t guarantee success in sex; even if you’re smaller, you can still bring her pleasure.
