How To Find Your Ring Size
Measure Your Finger
1. Use a flexible measuring tape, a piece of string, or narrow ribbon.
2. Wrap it around your finger, which you’ll wear your ring on. If using string or ribbon, mark the meeting point with a pen.
3. Place the string or ribbon on a flat surface and measure the marked length in millimetres (mm) with a ruler. Compare your measurement to the size chart above to find your ring size.
If you’re between sizes, choose the larger size for a comfortable fit.
Measure an Existing Ring
This is a great method if you’re surprising someone with a gift or treating yourself.
1. Select a ring that fits the intended finger comfortably.
2. Measure the internal diameter of the ring in millimetres (mm).
3. Use the size chart above to find the closest size.
