Kristallrummet's guide to measuring your ring size

Our rings are usually measured in US/Asian sizing.

How to measure your ring size with an existing ring:
Use a ruler or tape measure and place it on a flat surface. Take your ring and place it on the ruler/tape measure to read the inside diameter in mm; this measurement corresponds to your ring size.

Example: If the inside diameter of your ring measures 18 mm, then it is a size 8. 
Be precise when taking the measurement, as every millimeter matters and can make a big difference in finding the right ring size!

How to measure your ring size without a ring:

1. Take a piece of string or ribbon and wrap it once around your finger.
2. Form a "ring" and measure the string/ribbon where it meets by placing it against a ruler.
3. The measurement you get in millimeters is the ring size you should choose.

Example: If the inside measurement of the string is 17 mm, you should choose ring size 7.

Please note that the width of the ring can be crucial in choosing the size; a wide ring may require a larger size than you normally wear.

A tip is to measure your ring size both in the morning and in the evening. Both heat and cold can affect the size of your finger!
