Ring size guide
The Charisma Ring comes in US sizes 7 to 13. A smart ring fits a little differently from jewelry, so take a minute to measure before you order.
How to measure
- Choose your finger. Most people wear Charisma on the index finger of their non-dominant hand. The fit should be snug, without pinching.
- Measure at the end of the day. Fingers are slightly larger in the evening and when warm.
- Wrap a strip of paper around the base of the finger, mark where it overlaps, and measure the length in millimetres. That is the circumference.
- Find your size in the table. If you are between two sizes, choose the larger one.
- Check the knuckle. The ring has to slide over it. If your knuckle is much wider than the base of your finger, measure the knuckle instead.
