Ring Size Guide
A well-fitting ring should slide on comfortably and come off with light resistance. To help you find your perfect fit, we offer two simple at-home methods — plus a reusable ring sizer if you prefer extra precision.
How to Measure Your Ring Size
Option 1: Measure a Ring You Already Own
- Choose a ring that fits the intended finger well.
- Use a ruler or caliper to measure the inside diameter (straight across the centre) in millimetres.
- Compare your measurement to the chart below to find your corresponding size.
Option 2: Measure Your Finger
- Wrap a strip of paper or string snugly around the base of your finger.
- Mark where the ends meet and measure the length in millimetres.
- Match your result to the “Inside Circumference” column in the chart below.
Tip: Measure your finger at the end of the day when your hands are warm and slightly expanded. Avoid measuring when your fingers are cold, as they may be temporarily smaller.
