Use an existing ring that fits on the ring finger
Measure the internal diameter (mm) of the ring
We strongly recommend having your ring size professionally measured for the most accurate fit. Ring sizing is a personal preference. Rings should have some resistance going over the knuckle and feel snug but comfortable at the base of your finger.
Size will fluctuate with factors such as climate and hydration. Measure your finger at different times to get an average. Band thickness also impacts fit. Wider bands and stacked rings will likely require sizing up.
