Terms & Conditions

Last updated: 7 October 2026

These terms explain how to use RingFit and the limitations of its ring size estimates. Use the tool only if you accept these terms.

Purpose of the service

RingFit provides general ring size estimates for personal reference. It is not a professional jewellery fitting service, a purchase recommendation or a promise that a ring will fit. No payment or purchase is required to use the calculator.

Your measurements and calibration

You are responsible for selecting the correct units and measurement type, calibrating the screen carefully and checking the result. Use the ring’s inside opening, not the metal band. Recalibrate after changing display settings, zoom or screens. Place objects gently on a screen and avoid anything that could scratch or damage it.

Accuracy and fit

Measurements depend on your input, display scale and positioning. Reference charts are rounded, and regional conventions, brands and ring styles can differ. Confirm the result with the intended retailer or a physical ring sizer before ordering. RingFit’s jewellery estimates should not replace a smart ring manufacturer’s sizing kit.

Acceptable use

Use the website lawfully. Do not attempt to disrupt the service, bypass its access restrictions, introduce harmful code or interfere with other visitors. You may use your own calculated results for personal comparison and shopping.

Content and external links

The website’s original text, design and code remain subject to applicable intellectual property rights. Third-party names, trademarks and reference material belong to their respective owners. External links are provided for reference and do not imply endorsement or affiliation.

Availability and changes

The tool is provided as available. Features, reference charts and these terms may be revised. Access may be interrupted for maintenance or technical reasons. Keep an independent record if you need to retain a measurement, because the tool does not save results between visits.

Responsibility

To the extent permitted by applicable law, RingFit does not guarantee uninterrupted service or the accuracy of a home measurement and is not responsible for losses caused by relying solely on an estimate. Nothing in these terms excludes rights or liabilities that cannot lawfully be excluded, including applicable consumer rights.

Privacy and questions
