Notes:
1. Measure your finger in warm temperatures at the end of the day.
2. If your knuckle is a lot larger than the base of your finger, measure both the base of your finger and your knuckle and select a size between the two.
3. When considering a wide band, move up a size from your measurement, for comfort’s sake.
4. The most popular ring size are 7(U.S) & 8(U.S).
