Bra Size Calculator

According to statistics, more than 80% of women worldwide wear the wrong size underwear every day. That’s a pretty sad statistic, isn’t it? And it affects your posture, causing constant discomfort and back pain. You might think it’s just because you’re too active, but in reality, it’s simply a matter of choosing the right underwear. Fortunately, our bra size calculator will help improve your body’s health for you. Let’s break down how quickly it works and why it’s so important to know your exact measurements.

Let’s start with the basics: a woman’s breasts don’t have their own muscles; they’re supported solely by skin and ligaments. If your underwear is the wrong fit, these ligaments stretch, leading to loss of shape. That’s why the right bra size will not only preserve your health but also maintain the aesthetic appearance of your breasts for years to come. Some women buy the same size underwear for years without even considering that their body measurements are constantly changing. Any weight fluctuations and hormonal changes cause changes in chest volume. And before you figure out how to determine your bra size, understand the potential consequences of choosing the wrong one. A band that’s too tight disrupts blood circulation and makes breathing difficult, and later causes discomfort in the rib area. Conversely, a band that’s too loose shifts the entire weight of your breasts onto your delicate shoulders and neck. Also, if you haven’t accurately determined your bra cup size, the underwires can injure the delicate breast tissue, and your breasts will bulge unattractively out of the bra. Before using the bra size calculator on our website, you’ll need a soft measuring tape and a mirror. To ensure your bra size is as accurate as possible, follow a few simple rules. First, it’s best to take measurements while wearing thin, non-padded underwear without a push-up effect. If your breasts have lost their firmness, measure yourself in the most comfortable basic bra with soft cups. Second, pay attention to your posture. Your back should be perfectly straight, your shoulders relaxed, and your breathing calm. Do not suck in your stomach or hold your breath. Third, the measuring tape must always be held strictly parallel to the floor. Any tilt in the tape will distort the results. Doing this at home is easier than ever.

Step one: measure your bra size by taking the underbust measurement. The band supports up to 80% of the breast’s weight, so it must fit perfectly. Stand in front of a mirror. Wrap the measuring tape around your ribcage just below the base of your breasts. Make sure the tape lies flat, parallel to the floor. It shouldn’t sag on your back, but it also shouldn’t dig into your skin painfully. Exhale gently and press the tape firmly against your body. Record the measurement; this number will serve as the basis for determining your waist size (e.g., 70, 75, 80 in the European system). Now determine your cup size based on your bust measurement. Wrap the tape measure around your torso again, but this time position it at the fullest part of your bust (usually at nipple level). You don’t need to pull the tape tight; it should fit your body fairly loosely. Make sure the tape is at the same level on your back as it is in the front. No diagonal lines! Write down the second measurement. Now you have two main measurements. These are exactly what you need to get your personalized result in our online calculator.

The calculation uses your second measurement (chest circumference) and subtracts the first (underbust circumference) from it. The resulting difference in centimeters determines your cup size. For example: A difference of 10–12 cm usually corresponds to an AA cup. A difference of 12–14 cm is an A cup. A difference of 14–16 cm corresponds to a B cup. A difference of 16–18 cm corresponds to a C cup. A difference of 18–20 cm corresponds to a D cup. A difference of 20–22 cm corresponds to an E cup (or DD in some systems). A difference of 22–24 cm corresponds to an F cup, and so on. Manufacturers from different countries use different sizing systems. The world of lingerie is incredibly diverse, and unfortunately, there is still no single standard. But the online bra size chart is already built into our generator; you just need to specify your location or where you’ll be ordering lingerie from. Keep in mind the most popular standards: in most countries in continental Europe, the underbust measurement is rounded to the nearest number that is a multiple of 5 (for example, 65, 70, 75, 80). In the US and the UK, the imperial measurement system is used. Underbust measurements are denoted by even numbers (30, 32, 34, 36, 38). However, the UK has a unique cup size system: after D comes DD, then E, F, FF, G, GG, H, HH. As you can see, determining your bra size manually when shopping for products from different countries is no easy task, so feel free to visit our website anytime.
