Japanese Size Chart
To determine your ring size,
measure the circumference of your finger in inches or millimeters (a piece of
string or strip of paper no wider than 1/4 inch wide will do). Mark where the loose end touches, measure the marked length with a
ruler, then use the table below to
determine the closest size.
