How to measure your ring size
1. Using an existing ring
Choose a ring that fits the finger you want to size.
Measure the inner diameter in mm. on a ruler
Use the chart below to find your size in "diameter mm".
2. Using a measuring strip
Wrap a soft measuring tape or strip of paper around your finger at the base.
Make sure it feels tight but comfortable.
Mark where the ends overlap. Measure it with a ruler and compare it to the chart with the "EUR Circ. mm".
Tips for accuracy
- If you are between sizes, we recommend sizing up.
- If you know the size for your ring finger but you want to purchase a ring for your index finger, in general, the index finger is approximately four sizes bigger than your ring finger. i.e., ring finger size 50, index finger size 54.
