1. Create a Tool

You will create a tool using a piece of string or slim strip of paper. You will need a pen and a ruler.

 

2. Measure in Millimeters

Using your tool, wrap it around your ideal finger. With a pen, mark where the end of your tool meets the other end.
Unwrap the tool from your finger, and measure it alongside a ruler on the centimeters (cm) side. Measure from the end of your tool to the pen marking in order to find the precise measurement in millimeters (mm).

 

Keep in mind: There is 10 mm per 1 cm 

 

3. Analyze and Choose Size

Find your measurement (mm) in the chart below. Choose the closest number to your measurement and reveal your ring size!

 

Tips:

1. Wrap the tool around your finger tightly as the material (paper or string) can loosen up-not too tight where the rest of your finger is bulging.

2. Round your measurement +/- to the closest number (i.g. if your measurement reads 60mm, then your best bet would be size 9 (59.5mm).
