A starting point, not a guarantee

Our tools and guides give general information to help you choose bras. A calculated size is a suggested starting size. It cannot guarantee that a bra will fit, because fit depends on your shape and on how each brand and style is made. Check the retailer’s size guide before you buy, and check the fit when you try a bra on.

Not medical advice

Our content is about how clothing fits. It is not medical advice and cannot assess any condition. If you have pain, skin damage or breast changes, speak to your GP or another health professional.

Accuracy and corrections

We base our tools on published sources and show when we checked them, but brands change their charts and we can make mistakes. If something looks wrong, please tell us. Our method explains how the tools work and their limits.

Other websites

Links to brands and retailers are for convenience. We are not responsible for their content, prices, stock, delivery or returns, and any purchase is made with the retailer, not with us.

Trademarks

Brand names belong to their owners and are used only to identify them. Mentioning a brand does not imply any partnership or endorsement.

You may use the site and tools for personal, non-commercial purposes. Please do not copy substantial parts of the site or try to disrupt the service.
