A good ring fits snugly but comfortably, sliding over your knuckle. 

💡 Tips: Consider Temperature and Fit Preferences

  • Fingers may swell slightly in warm weather and shrink in cold temperatures.
  • If you are between sizes, opt for the larger size for comfort.

 

Using a Ring You Own

  • Measure the inner diameter of a well-fitting ring with a ruler or calliper.
  • Compare the measurement with the diameter column in the size chart.

Using a String or Paper Strip

  • Wrap a thin strip of paper or string around the base of your finger.
  • Mark the spot where the ends meet and measure the length in millimetres (this is the circumference).
  • Match your measurement to the circumference column in the chart.
