Terms of use

Measure Ring Size is provided free of charge for personal use: measuring ring size at home and converting between international size systems. You may use the tools, chart, and guides as often as you like. You may not present the site's content as your own, or use automated means to copy the site at a scale that degrades it for others.

Results are guidance based on the measurement you provide and the chart stated on the methodology page. Home measurements are approximate, and fit also depends on band width, knuckle size, temperature, and the jeweller's own sizing. The site does not guarantee that a ring ordered using these results will fit, and is not responsible for exchange, resizing, or return costs. For high-value purchases, confirm with a professional fitting.

There is no account system in this stage and no personal data is collected by the site itself (see the privacy policy). The site is provided as-is: it may change, add pages, or be unavailable at times, for example during deployment or maintenance. If these terms change, the new version will be published on this page.
