This calculator estimates bra size based on bust size, frame size, and common measurement standards. Also, convert bra sizes in the US, UK, EU, and Australia.

The size of a bra always depends on two factors: the circumference of the body just below the breasts (called band size) and the circumference above the breasts, usually at the level of the nipples (called bust size).

A bra size calculator is a tool that helps determine your correct bra size by using bust and band measurements. By inputting these values, the calculator provides a size that aligns with regional sizing standards, ensuring better comfort and fit.
