How do I know what my ring size is?
Measure the inside diameter of an old ring by printing out the inner diameter ring diagram. Look for the circle that is closest to your ring’s inner diameter by placing your ring on the diagram, and use this measurement to place your order.
(Please be reminded to print with NO SCALING and ensure that the scale of the printed chart is correct by measuring the rectangle on the chart as 2cm x 4cm.)
Inner Diameter of Ring
Measure the circumference of the base and knuckle of your finger, by using a non-elastic string or tape measure. Use the table below to convert the larger of the two measurements to the equivalent U.S. Standard ring size and place your order accordingly.
All sizes stated on our websites are U.S. Standard ring sizes, if you already know what your size is in another metric other than the U.S. Standard ring size, you can take the conversion chart as reference, and order your respective U.S. Standard ring size.

When you measure the finger…Your ring should fit your finger comfortably. It has to be loose enough to go through your knuckle as it will be the biggest part of your finger while it has to be tight enough that it will not fall off.Finger size varies slightly at different times of day and under different weather. It is best to measure your finger size a few times during the day when fingers are warmer. Fingers are usually slightly bigger when they are warmed up after you use them and measuring it a few times is to ensure you have got the most accurate measurement. If the ring falls within two sizes, order the bigger one.
