To find your ring size, choose from our two measurement methods:

Method 1:

First, prepare a ruler and a ring that fits you well. Measure the diameter of the ring and then refer to the table above to find your ring size.

If you have a ruler that is accurate to half a millimeter, please use it as a priority (as shown in the left picture). If you don't have one, you can use a regular ruler (as shown in the right picture).

*Note: Be sure to measure from the inside of the ring, not the outside.

Count how many 1mm increments there are and estimate the decimal point to get the diameter. Then refer to the table above to find your ring size. For example, if the diameter of this ring is approximately 16.5mm, then the ring should be a Hong Kong size 13 ring.

  1. Please download the provided Ring Size Guide and print it out in a 1:1 scale.
  2. After printing, before using it officially, please measure the 3cm mark on the paper with a ruler. If the printed mark matches the mark on the ruler, you can start using the chart.
  3. Place an existing ring flat on the circle, preferably a ring with a smaller main stone or no main stone at all.
  4. When measuring, please make sure the circle is not completely covered by the ring, ensure that you can see the complete circle from inside the ring and there are no white gaps.

Look carefully when measuring your ring size
