Using the site
KnowHerSize at knowhersize.com is run by SIA „Vizo Media”, registration number 40203420359, Latvia (info@knowhersize.com). By using the site you agree to these terms. If you do not agree, please do not use it.
The site is free to use for personal, non-commercial purposes.
Sizes are guidance, not a guarantee
The calculator, charts and converters give estimates based on general sizing rules and the information you enter. Sizes vary between brands and styles, and bodies change over time. Each result shows a confidence level, and some methods only give a range.
We cannot guarantee that a size will fit. Check the retailer’s own size chart and returns policy before you buy, and try items on where you can.
Not medical advice
The site is about clothing fit. It is not medical advice. If you have pain, a medical condition, or questions about breast health, speak to a health professional.
No affiliation
KnowHerSize is independent. Brand and retailer names, where mentioned, are used only to describe sizing, and their owners do not endorse this site.
Advertising and links
The site does not show ads. Links to other sites are provided for convenience, and we are not responsible for those sites.

The text, design and code of the site belong to SIA „Vizo Media” unless stated otherwise. You may share links to any page. Please do not copy substantial parts of the site without permission.
Liability
We provide the site as it is and do our best to keep it accurate. To the extent the law allows, we are not liable for losses arising from use of the site, including the cost of items that do not fit. Nothing in these terms limits rights you have under consumer law that cannot be excluded.
Changes and governing law
We may update these terms. The date at the top shows the latest version. These terms are governed by the laws of the Republic of Latvia.
