💡 How do you determine your ring size?
Option 1: With an existing ring
Choose a ring that fits well on the finger for which you are looking for a new ring.
Measure the inside of the ring (diameter in mm).
Compare with the table above to find your size.
Option 2: With a piece of paper or string
Cut a thin strip of paper or take a thin piece of string.
Wrap it around the finger where you want to wear the ring – not too tight!
Mark where the strip or string meets.
Measure that length in millimeters = your circumference → compare with the table.
Tips:
It is best to measure your finger at the end of the day (fingers can swell).
Avoid measuring when your fingers are cold – they may be slightly smaller.
If you're between two sizes, choose the larger one.
