Ring Sizing Guide

Things to bear in mind while measuring your finger size:

  • Time & temperature: Measuring the ring in cold or in hot temperature will affect the ring size measurement. Checking your finger size at the end of the day when it is at is largest.
  • Ring width: Wider rings feel tighter than thinner rings. Choose a half size bigger for ring widths that are 4.0mm or more. 
  • Comfortable and secure: Ensure that your ring is secure but can still slide over your knuckle.
  • Shape of finger: If your knuckle is larger than average, please make sure you size for a slightly larger ring size to ensure comfort.
