How to measure your ring size at home:
Wrap a thin strip of paper or string around your finger. Mark where it meets, then measure the length in mm — that's your circumference. Divide by π (3.14) for the inner diameter. For the best fit, measure at the end of the day when fingers are slightly larger. If between sizes, choose the larger size.
