Terms & conditions

By using CheckMyRingSize.com, you agree to the terms below. If you don't agree with them, the simplest option is not to use the site, nothing here requires an account or payment, so there's no cost to walking away.

The calculator is a sizing aid, not a guarantee

Check My Ring Size is provided to help estimate ring size using self-reported measurements and screen calibration. Screen calibration, manual measurement, and browser rendering can all introduce small errors, we say so directly on the calculator itself. For anything irreplaceable, an engagement ring, a significant gift, confirm the size with a professional jeweler before ordering. We don't promise a specific level of accuracy, and results should be treated as a strong estimate rather than a certified measurement.
