How to find your ring size
Method 1: measure your own finger
Step 1: Cut a strip of paper.
Step 2: Wrap the strip of paper around the base of your finger and mark where the paper meets. (Ensure there is enough space to slide the ring over your knuckle.)
Step 3: Use a ruler to measure the distance between the markings.
The measurement you obtained is the circumference of your finger, which corresponds to the European ring sizing. For example, if it measures 5.4 cm, you should choose size EU 54. If you find yourself between sizes, we recommend selecting the larger size.
Method 2: measure your own Ring
Step 1: Take a ring that you know is the correct size.
Step 2: Lay the ring on a flat surface and place a ruler on top of it.
Step 3: Measure the inner diameter of the ring.
The measurement you obtained is the inner diameter of the ring. Refer to the chart provided below to find the corresponding ring size.
