Our handy bra size calculator helps you avoid confusing numbers and charts by providing you with an accurate bra size in 3 easy steps. Get your measuring tape ready and let's begin!

Exhale thoroughly, and wrap the measuring tape around your ribcage under your bust. The tape should be parallel to the ground. Round the measurement to the nearest whole number

Stand straight and measure the fullest part of your bust, passing through the nipples. You should be taking the measurement without a bra or with a non-padded bra if needed. The tape should be parallel to the ground and secure but not binding.

Bra Sister Sizing

Is the bra that you want unavailable in your size? Try its sister size! Each bra size has 2 possible sister sizes.
