Ring Size Guide

Not sure of your size? The most accurate way to find your ring size is to visit a local jeweler — they have professional tools and can measure your finger precisely in just a few minutes. I always recommend this!

If you can't get to a jeweler, here's how to measure at home: wrap a thin strip of paper or a piece of string snugly around the base of your finger (not too tight — you should be able to slide it off comfortably). Mark where it overlaps, then lay it flat and measure the length in millimeters. That number is your EU ring size.

Note: fingers can swell slightly in heat or at the end of the day, so measure at room temperature and try a few times for accuracy.

US and UK conversions are approximate. Unlike the EU system, US and UK sizing can vary slightly between brands — when in doubt, get measured by a jeweler.
