If you don't know your size, don't have an existing ring and you don't have a printer:
-
Get a piece of string or cut up a thin piece of paper (make sure the piece of paper is really thin or it won't be accurate!) and wrap it around your finger firmly. (make sure the paper/string sits very firm on your finger and how you would want the ring to fit; that means it should not be loose and not extremely tight)
-
Mark the string or piece of paper to get the circumference (in mm)
-
Lay the string or paper down against a ruler to measure the circumference (in mm/cm)
-
Please use the table above to measure your circumference (in mm) against the US sizing column (We use standard US sizing)
-
Please choose the ring size that is closest to your circumference if you are in-between sizes.
Tips:
-
The average ring size for women is US 6-7.
-
Please measure your finger when they are warm as cold fingers will measure smaller.
