Kherish® Ring Size Guide | International Conversion Chart

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

  1. Select a ring that fits the intended finger comfortably.

  2. Measure the inside diameter (from edge to edge) in millimeters.

  3. Match your measurement to the chart below to find your U.S. size.

Option 2: Measure Your Finger

  1. Wrap a thin strip of paper or string snugly around the base of your finger.

  2. Mark where the ends meet, then measure the length in millimeters.

  3. 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.
