Important Tips

  • Best time to measure: Measure your finger at the end of the day when it's at its largest
  • Temperature matters: Cold fingers are smaller, warm fingers are larger
  • Knuckle consideration: Make sure the ring can slide over your knuckle comfortably
  • Wide bands: Order 1/2 size larger for bands wider than 6mm
  • Between sizes: If you're between sizes, choose the larger size for comfort
