FK U** RINGS
How to measure
Take a thin strip of paper. Wrap it around the finger you want to wear the ring on. Mark where it overlaps. Lay it flat and measure the length in millimeters. That is your inner circumference. Find it in the table below.
If you prefer to work with diameter instead — divide your circumference by 3.14.
Measure at the end of the day. Fingers are slightly larger in the evening and in warm weather. If you are between two sizes, choose the smaller — your order already includes a half size up.
