The Paper Strip Test:

Step 1: Cut a strip of paper or a piece of string.

Step 2: Wrap it around your finger snugly (not too tight, aim for a comfortable, snug fit).

Step 3: Use a pen to mark the string on paper where the long end overlaps. 

Step 4: Measure the length with a ruler and compare your measurement to our sizing chart. The length of your paper is equal to the inner circumference shown below. If the measurement falls in between two sizes, it is recommended that you choose the larger size.

Ring Size Diameter (mm) Circumference (mm)
4 14.8 46.8
5 15.7 49.4
6 16.5 52
7 17.3 54.5
8 18.2 57.2
9 19 59.8
10 19.8 62.2
11 20.6 64.8


If You Already Own A Ring:

For those who already have a ring that fits them but are unsure what size it is, you can measure the diameter and match the result with the appropriate ring size. We created a chart that tells you what the inner diameter is for each ring size.
