Use this bra size calculator to find your perfect fit comfortably and with ease.
How to Use the Bra Size Calculator
To use this calculator, you need two measurements: your underbust and bust measurements in inches. Enter these values into the corresponding fields above and click “Calculate” to receive your bra size.
How It Works
This calculator takes your underbust measurement and rounds it up to the nearest even number to find the band size. For bust sizes under 30 inches, it adds 4 inches, and for sizes 30 inches or above, it adds 2 inches. It then calculates the difference between the bust measurement and the rounded underbust size to determine the cup size. A difference of 1 inch or less corresponds to an AA cup, 2 inches to an A cup, and so on through the alphabet, with each inch increasing the cup size by one letter.
Limitations
This calculator provides an estimate based on standard bra size conventions. However, bra sizes can vary between different manufacturers and styles. For the most accurate fit, a professional fitting is recommended. Additionally, this calculator does not account for half sizes and may not cover all possible cup sizes.
