Terms & Conditions

1. Free tools, no account

We provide free ring-sizing tools: an on-screen ring sizer, finger-width calculator, international size converter, reference charts, brand guidance and a printable 1:1 guide. No registration or payment is required, and we may modify, suspend or discontinue any part of the service at any time.

2. Measurement accuracy disclaimer

Our conversions follow ISO 8653:2016, BS 6882 and US standard sizing, but on-screen and at-home results depend on factors outside our control — display calibration, print scaling, finger swelling, temperature, ring width and band style. Treat results as a close estimate, not a guarantee.

Always confirm with a professional jeweler before ordering expensive, custom or engraved rings. We are not responsible for rings ordered in the wrong size, resizing costs, or returns.

3. Acceptable use

You agree not to:

• Misuse the tools, interfere with the site, or attempt to disrupt, scrape abusively or circumvent security.
• Copy, republish or redistribute substantial portions of our content or charts without permission (brief quotations with attribution are fine).
• Use the site for unlawful purposes or to infringe the rights of others.
• Imply endorsement or affiliation with us without written consent.

4. Intellectual property

The site's design, text, graphics, tools and code are owned by Ring Size Finder or its licensors and protected by intellectual-property laws. You are granted a personal, non-exclusive, non-transferable licence to use the tools for personal, non-commercial purposes. Standard ring-size facts (e.g. "US 7 = 17.3 mm") are not owned by anyone; our particular expression of guides and charts is.

5. Third-party links & references

We reference third-party brands (such as Oura, Cartier, Tiffany & Co. and Pandora) purely for sizing compatibility information. Those trademarks belong to their owners; we are not affiliated with or endorsed by them. Any external links are provided for convenience — we do not control third-party sites and are not responsible for their content or practices.

6. No professional advice

Content on this site is general sizing information, not professional jewellery, medical or financial advice. Finger size can be affected by health conditions — consult an appropriate professional if you have concerns.

7. Limitation of liability

To the maximum extent permitted by law, the site is provided "as is" without warranties of any kind. We disclaim all implied warranties, and we will not be liable for indirect, incidental, consequential or special damages arising from your use of (or inability to use) the site — including costs of resizing or replacing rings. Where liability cannot be excluded, it is limited to the minimum amount permitted by law.

8. Privacy

Your use of the site is also governed by our Privacy Policy, which explains our minimal, privacy-friendly data practices.

9. Changes & contact

We may update these Terms as features or laws change; continued use after updates constitutes acceptance. Questions about these Terms: contact@ringsizefinderonline.com or via our contact page.
