Use a measuring tape to measure your band size (around your ribcage) and bust size (around the fullest part of your chest). Then enter these values into our calculator.
You can measure in either inches or centimeters — our bra size calculator supports both.
It’s accurate for most users, but body shapes differ, so always try the size and see if it feels comfortable.
Band size is the measurement around your ribcage, just under your bust.
Bust size is the measurement around the fullest part of your chest.
