Write to hello@ringsizecalculator.online — for example with a chart correction (tell us the jeweller and the mm measurement), a tool bug (tell us your device and what you entered), or a guide suggestion.

This page intentionally has no contact form: a form would need a backend service to receive messages, and email does the same job with no middleman storing your address. Your mail app will open when you tap the address above.

Before writing, the FAQ answers most sizing questions instantly, and the calculator and on-screen sizer need no account or message at all. About the site: about us.
