Important Tips

  • Measure at the end of the day - Fingers swell throughout the day
  • Measure multiple times - Take 3-4 measurements for accuracy
  • Consider width - Wider rings (8mm+) may need to be 1/2 size larger
  • Account for knuckles - Ring must fit over your knuckle but not be loose at the base
  • Temperature matters - Cold fingers are smaller, warm fingers are larger

Between Sizes?

If you're between sizes, we recommend:

  • For wider rings (8mm+): Go up to the larger size
  • For narrow rings (6mm or less): Go with the smaller size
  • For comfort fit rings: These fit slightly tighter, consider going up 1/4 size
