What this site provides

Bra Size Calculator Pro provides measurement-based starting-size guidance, international size conversion, sister-size lookups, a fit-checking questionnaire and educational guides about bra sizing and fit. Every result is a starting point, not a guarantee that any specific product will fit - see our methodology page for exactly how each tool works and its limitations.

No professional or medical advice

Nothing on this site is medical advice. Content involving pain, skin changes or other physical symptoms directs you to seek appropriate care - it does not diagnose anything. See our Medical Disclaimer.

Accuracy

We work to keep our calculations, conversions and guides accurate and aim to correct errors promptly once reported - see Contact and Corrections. We do not guarantee that any result, conversion or piece of content is free of error.

Acceptable use

Use this site's tools and content for personal, non-commercial reference unless you have our written permission for another use. Don't attempt to disrupt the site or extract data from it at a scale that affects other visitors.

Intellectual property

The text, illustrations and calculation methodology on this site are our own work unless otherwise credited. You may link to and quote this site with attribution; wholesale republishing of our content elsewhere is not permitted without permission.

Changes to these terms

We may update these terms as the site changes. Continued use of the site after an update means you accept the current version.
