Finding your perfect ring size ensures your Kherish piece fits beautifully and comfortably. Whether you’re purchasing for yourself or as a gift, this guide will help you measure accurately and understand how ring sizes convert internationally.
How to Find Your Ring Size
Option 1: Measure an Existing Ring
-
Select a ring that fits the intended finger comfortably.
-
Measure the inside diameter (from edge to edge) in millimeters.
-
Match your measurement to the chart below to find your U.S. size.
Option 2: Measure Your Finger
-
Wrap a thin strip of paper or string snugly around the base of your finger.
-
Mark where the ends meet, then measure the length in millimeters.
-
Use the circumference column in the chart to find your corresponding size.
Pro Tips:
-
Measure your finger at the end of the day, when it’s slightly larger.
-
Avoid measuring when your hands are cold or wet, as fingers may shrink.
-
If you’re between sizes, we recommend choosing the larger size for comfort.
