How to Measure Your Ring Size at Home
If you don't know your size, you can easily find it using one of these two simple methods:
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.
- Or stop by our showroom anytime, and we'll take your ring size in person.
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 or stop by our showroom.
