Helpful Tips When Measuring:

  • For the best comfort fit, measure your ring size at the end of the day when your fingers are warm. Please also note that the fingers on your dominant hand are usually larger.
  • Consider width. The wider the band, the tighter the fit may feel. You may need to go up by a half size for a more comfort fit.
  • Your perfect fit ring should be snug enough that it does not fall off after a good shake of your hand, but loose enough to slide easily over your knuckle.
