HOW TO MEASURE RING SIZE
MEASURE AN EXISTING RING
1. Select a ring that properly fits the intended finger.
2. Use a ruler to measure the inside diameter of the ring. This measurement, expressed in mm, can be used to determine the correct ring size.
Step 1 – Download and print out the ring size chart below at 100% and make sure the line at the bottom of the image measures exactly 135mm.
Step 2 – Place your ring so that it sits on top of a black circle, with the black circle touching the inside edge of your ring. This will give you your correct ring sizing.
* Sizes in the ring size guide chart are in U.S. sizes and ring size measurements are in millimeters.
** Finger size can vary throughout the day and depending on weather conditions. For a more correct measurement, we recommend measuring your finger several times in the same day and even different days, so that you can compare the measurements – It is better to avoid measuring the finger in case of cold or wet hands: the measurement would be less to the real one.
