Measuring Your Ring Size with String
1) Take a length of floss or string and wrap it around the base of your finger . Mark where the floss or string first overlaps with a pen.
2) Stretch the length of string out along a ruler or measuring tape, and take down the length in millimeters.
3) Use the ring size chart to compare your measurement to the standard ring size diameters. For example, a size 6 ring is 16.45 mm, a size 7 ring is 17.3 mm, and a size 5 is 15.6mm.
