Rubeeka Size Guide
Find Your Perfect Bra Size
A comfortable and well-fitted bra starts with the right measurement. Use this simple Rubeeka guide and calculator to measure your band size, cup size, and estimated international bra size before shopping online.
How to Measure
Please measure in centimeters only. For best results, use a soft measuring tape.
1
Wear a normal bra while measuring. Avoid heavily padded bras because they can change the actual measurement.
2
Measure tightly around your underbust. This measurement helps you find your bra band size.
3
Measure loosely around the fullest part of your bust. Keep the tape straight and comfortable.
4
Cup size is calculated by subtracting your underbust measurement from your bust measurement.
