Wearing the right bra size is essential not just for comfort, but also for posture, confidence, and overall breast support. Surprisingly, many women wear the wrong size without realizing it. The good news is that you can accurately measure your bra size at home with just a measuring tape and a few simple steps.

Start by measuring your underbust, which is the area directly below your breasts. Make sure the tape sits snugly around your ribcage and remains straight across your back. This measurement determines your band size and should be taken while exhaling naturally. Round the number to the nearest whole number for accuracy.

Next, measure your bust size by wrapping the tape around the fullest part of your breasts. The tape should feel comfortable, not tight, and should again be level across your back. Wearing a lightly padded or non-padded bra while measuring helps get the most accurate result.

Once you have both measurements, subtract the underbust measurement from the bust measurement. The difference helps determine your cup size. A smaller difference means a smaller cup, while a larger difference indicates a fuller cup. Together, your band and cup measurements give you your ideal bra size.

It’s important to remember that your bra size can change over time due to weight fluctuations, hormonal changes, pregnancy, or lifestyle shifts. Measuring yourself every six to twelve months ensures that your lingerie continues to fit and support you properly.
