Bra Size Calculator

Our calculator helps you understand which bra size to order based on how you like your bra to feel. We use UK sizing as most of our brands are British, but you'll see your North American size too for reference.

When measuring be sure to keep your tape measure level with the ground all the way around your body for accurate results. Wear your best fitting bra (not molded, padded or sports). For more information on how to measure yourself click here.

* Please note that we do not use the plus 4 method so this calculator may not be suitable for women up to a C cup.
