How do I convert my ring size between different countries?

Select your current region and size, pick the target region, and convert—or use By Measurement mode with circumference or diameter.

What measurements do I need?

Circumference or diameter in mm or inches. Wrap a soft tape at the ring base, or measure an existing ring.

Conversions follow standardized international tables. Brand fit can still vary—try on when possible.

Use a soft tape or string at the ring base, mark the overlap, measure the length at room temperature.

Convert ring sizes across US, UK, EU, Asian, Indian, and Italian/Swiss standards—or find your size from finger measurements.
