Helpful Tips

  • Measure at the end of the day - Fingers are slightly larger in the evening
  • Temperature matters - Cold fingers are smaller, warm fingers are larger
  • Wider bands fit tighter - Consider going up half a size for bands wider than 6mm
  • Measure multiple times - Take 3-4 measurements to ensure accuracy
  • Different fingers, different sizes - Don't assume all your fingers are the same size
  • Between sizes? - We recommend sizing up for comfort
