💖 About the Bra Size Calculator

The Bra Size Calculator is a simple and accurate tool designed to help women find their estimated bra size from the comfort of their home. By entering your underbust (band) and bust (fullest part) measurements, the calculator quickly determines both your band size and cup size using either modern or traditional sizing methods.

This tool automatically converts between inches and centimetres, giving you flexibility no matter where you live. The result provides an estimated bra size (for example, 34C or 75D), along with a clear explanation of how the measurement difference determines the cup letter.

While this calculator gives a reliable estimate, remember that bra sizing can vary between brands and styles. Use this as a starting point and try on a few sizes to find your perfect fit. For the most precise results, consider a professional fitting at a lingerie store.
