Ring Sizer

Below are three easy ways to measure your ring size at home.

Remember that the size of your fingers usually differ from your right to your left hand, so make sure you measure the correct finger.

US Size	Circumference in mm	Diameter in mm
6	51.9	16.5
7	54.4	17.3
8	57	18.2

 

Method 1:

To determine a ring size in circumference, measure the relevant finger with a piece of wire, string, floss or paper. Mark the point where the two ends meet and measure the length against a ruler. This will identify the correct circumference. 

Method 2:

Simply measure the internal diameter of a ring you currently wear. Use the diameter measurements above to determine your ring size.

Method 3:

Use this link to a website that will help you determine your ring size based on an online chart. You will use a credit/debit card as a size reference as each screen size is different. You can then place a ring you currently wear on top of your screen to get the right size.
