Option 1: Measure An Existing Ring (inside diameter)
In this example: inside diameter is close to ~16.5mm - ring size is 6
1. Measure the inner diameter (mm) of your ring.
2. Refer to our ring sizing chart (diameter column) in order to determine your exact size.
Option 2: Measure Your Finger (circumference)
1. Cut a piece of thin paper.
2. Wrap it around your finger, just above the knuckle, and cut the paper where it overlaps.
3. Measure the length of the paper using a ruler or measuring tape to determine the circumference in mm.
4. Refer to our ring sizing chart (circumference column) in order to determine your exact size.
