By using Bra Size, you agree to these terms. If you do not agree, please do not use the site.
Our calculator is provided free of charge for personal, non-commercial use to help you estimate a bra size for shopping purposes. You may not scrape, republish, or embed the tool's code on another site without written permission.
Nothing on this site constitutes medical, health, or professional fitting advice. Results are a general estimate based on the measurements you supply and standard sizing conventions; they are not a substitute for an in-person fitting.
We work to keep our formulas and conversion tables correct and up to date, but sizing standards vary by brand and country, and we cannot guarantee that any specific garment will fit as expected.
The design, code, copy, and charts on this site belong to Bra Size and the Calculations.one network unless otherwise credited. You may share links to our pages freely.
Bra Size and its operators are not liable for any purchasing decisions, discomfort, or losses arising from reliance on the calculator's output. Use it as a guide, not a guarantee.
We may update, suspend, or discontinue any part of this site at any time without prior notice.
This site is intended for a global audience. Local consumer protection laws may still apply to purchases you make from third-party retailers linked from this site.
