Terms of use
The short version
This website provides free information and a free conversion tool about ring sizing. Use it freely. Check anything important with a jeweller before spending money on a ring.
Accuracy and no warranty
The guides, charts, converter and articles on this site are provided for general information. They are researched carefully and reflect the same conversion data used in the Ring Sizer app, but ring sizing depends on your fingers, the ring’s width and profile, the temperature, the time of day and the practices of the individual jeweller.
No measurement taken from this website or the app is a guarantee of fit. For expensive or non-resizable rings, meaning full eternity bands, tension settings, tungsten and ceramic, have the size confirmed by a jeweller before ordering. We accept no liability for a ring that does not fit, for resizing costs, or for any purchase decision made using this site.
The app
Ring Sizer for iOS is distributed through the Apple App Store and governed by Apple’s standard end user licence agreement together with any terms presented inside the app. It is free to download and offers optional in-app purchases. Nothing on this website forms part of that agreement.
Intellectual property
The text, layout, code and images on this site are the property of the site owner, except where noted. App screenshots and the app icon are the app’s own marketing assets. Apple, the Apple logo and App Store are trademarks or service marks of Apple Inc.
Independence
Ring Sizer is an independent app. It is not affiliated with, endorsed by or sponsored by any jeweller, retailer or standards body mentioned on this site. Ring size systems referenced here such as ISO 8653 are cited for accuracy, not as a claim of certification.
