Important Tips:

  • Measure your finger at the end of the day when it's largest
  • Avoid measuring when your hands are cold - fingers shrink in cold weather
  • For wider rings (above 6mm), go up half a size for comfort
  • The ring should slide over your knuckle with slight resistance but fit comfortably at the base

Between Sizes?

  • For a snug fit, choose the smaller size
  • For comfort or if your knuckle is larger, choose the bigger size
