The Crystal Room's Guide to How to Measure Your Ring Size

Our rings are usually measured in US/Asian sizes.

How to measure the size of a ring:
Use a ruler or tape measure and place it on a flat surface. Take your ring and place the ruler/tape measure on it to read the inner measurement in mm, these millimeters correspond to your ring size.

Example: The inner diameter of your ring measures 18 mm, then it is a size 8.
Be careful when reading the measurement, as every millimeter matters and can make a big difference in your search for the right ring size!

How to measure your ring size without ring:

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

Example: If the inner diameter of the band measures 17 mm, you should choose ring size 7.

Please note that the width of the ring can be decisive in choosing a size, a wide ring may require a larger size than you usually use.

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!
