 Measure an existing ring

• Select a ring that fits the desired finger perfectly.
• Use a ruler to measure the inside diameter of the ring in millimeters (mm).
• Check our size chart above under "Diameter" to find your match. Note: Do not measure the outside of the band, only the inner circle.

Important Tips for Accuracy

• Temperature matters: Measure your finger at the end of the day when your hands are warm. Cold fingers are often half a size smaller.
  
• The Knuckle Factor: Your ring should be snug enough not to fall off, but loose enough to slide over your knuckle with slight resistance.
  
• Band Width: If you are ordering a wide-band cocktail ring, we recommend choosing one EU size larger than your normal size for a comfortable fit.
  
• If you want to be 100% sure before you buy, have your size checked by a professional jeweler.
