Measure Finger Size (mm)
- Wrap a strip of paper or ribbon snugly around your finger, then use a pen to mark where the strip overlaps.
- Measure the marked strip with a ruler - ensure it’s exact and don’t round up! The ribbon or paper strip should be comfortable enough to slip on and off your finger easily.
Measure Ring ⌀ (mm)
- Using an existing ring that fits you well, place a ruler in front of the ring to measure the inside diameter.
- Match it to the closest size in the chart below. If you are between sizes, we recommend choosing the larger size.
