Your rings should fit comfortably, not too tight, but not too loose, either. It should be loose enough to slide over your knuckle and tight enough so that it can't fall off your finger.

1. Be sure that your fingers are warm; cold can shrink fingers up to a half size
2. Measure your fingers at the end of the day when they're largest
3. Measure your finger size a few times to make sure it's accurate
4. If the measurement falls between sizes, choose the larger size
5. Be sure to measure the finger on which you'll be wearing the ring
