How to use the calculator?

Our bra calculator is based on a few key measurements: underbust, bust, and cup size.

To get started, simply measure yourself with a soft measuring tape. Once you have your measurements, input them into the calculator, and voila!

It will tell you what size bra you should wear.

If you’re not sure how to measure yourself, don’t worry. We have a handy guide below that will walk you through the process step-by-step.

Bra size calculator in inches

Our calculator goes by inches, so please refer to the chart below to get your country bra size measurement.

To use this calculator, simply enter the measurements in inches into the corresponding fields and hit calculate.

Keep in mind that this is just an estimate, so if you’re in between sizes, it’s always best to try on both sizes and see which one is more comfortable.
