💡 Pro Tips for Accurate Measurement

  • Measure at the end of the day when fingers are largest
  • Measure when your hands are warm (cold hands shrink)
  • Measure 3-4 times for accuracy
  • Consider the width of the band (wider bands fit tighter)
  • Knuckles should fit comfortably through the ring
  • When in doubt, size up (easier to resize down)
