How to Use the Bra Size Calculator

1. Select Your Country
   Begin by choosing the country where you’ll be purchasing your bra. Options include the USA, Canada, UK, Europe, and France. This makes certain that your measurements are converted accurately according to the country’s sizing standards.
2. Choose Your Measurement Unit
   Next, select whether you’ll input your measurements in inches or centimeters (cm). This part makes it convenient regardless of which measurement system you’re comfortable using so you don’t have to convert it later.
3. Measure Your Underbust (Band Size)

4. Measure Your Bust
   Measure the biggest part of your chest, typically over your nipples, while keeping the measuring tape horizontal. Enter this number into the Bust Measurement field.
5. Click “Calculate Bra Size”
   Hit the big red button to calculate your bra size. Our tool will process your inputs to provide your band size, cup size, and full bra size, tailored to your selected country.
6. Review Your Results
   The calculator will display your:
   • Band Size: The numeric size corresponding to your underbust measurement.
   • Cup Size: Determined by the difference between your bust and band measurements.
   • Full Bra Size: A combination of your band size and cup size, e.g., 36C.

Our calculator accounts for country-specific adjustments and ensures you get accurate results, whether you’re shopping in the USA, Europe, or anywhere else.

• Make sure your measurements are taken while standing straight, with the tape snug but not compressing your body.

Why Use the Bra Size Calculator?

The best way to ensure the right bra fit is to try it on before buying. Unfortunately, with our busy lives, many women are forced to shop online, which means we need to know our correct bra size before making a purchase. The bigger the bust, the harder it is to calculate the correct bra size because there are so many variations when it comes to achieving the perfect fit. Fortunately, most online stores offer easy return policies if the bra doesn’t fit properly.

An uncomfortable bra can ruin your entire day. After all, it’s not like you carry different-sized bras to work every day. That’s why it’s crucial to wear the correct bra size—especially for work. The wrong size can cause skin irritation, rashes, and discomfort. In the worst-case scenario, if you’re bending over frequently or moving around a lot at work, a broken bra wire could stab you, and that’s never a good experience. Sports bras are an excellent alternative, and the process for calculating their size is the same as regular bras.

It’s fairly easy to measure your band and bust size if you’ve ever wondered how to measure bra size accurately. All you need is a soft measuring tape or even a string, and having a friend to help you will make it easier. To measure your band size, place the tape or string around yourself just below your bust. Hold it firmly but not too tight, and then measure the string or tape and round the number to the nearest inch or centimeter. To measure your bust, have your friend wrap the tape or string around the fullest part of your chest. Ensure it is straight, held firmly—not too tight or loose—and then record the number, rounding up if necessary. Our bra size calculator above will even determine your cup size, so with this information, you can confidently shop for bras online.

In today’s busy world, most of us don’t have time to visit a store to try on bras. Instead, we rely on online shopping. That’s why it’s important to educate yourself on how to measure your bra size and use accurate calculations to find the perfect fit.

Final Thoughts

We strive to provide the most accurate results with our bra size calculator. However, your personal style, fit preferences, and comfort level may vary depending on your daily routine and activities. Remember, there’s no such thing as one-size-fits-all when it comes to bras. It’s always a good idea to try them on, and if the measurements don’t match the fit you need, don’t hesitate to return the bra for a refund or exchange.
