Find Your Ring Size

Finding your perfect fit is simple:

1. Measure Your Finger:

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

  • Mark where the ends meet.

  • Measure the length in millimeters.

2. Measure an Existing Ring:

  • Use a ring that fits you well.

  • Measure its inner diameter in millimeters.

Tip: Fingers are slightly larger at the end of the day. If you’re between sizes, choose the larger size for comfort.
