Keeping this in view, how do I measure my ring size in mm?
You can measure your ring size using a string or floss. Wrap a string around your finger, marking where it first overlaps with a pen. Then, unwrap it and take down its length in millimeters.
Similarly one may ask, how many MM is a size 3 RING? With standard ring sizes, every half-size matches up to a 0.4 millimeter increment, starting with size 3 equaling 14 mm, size 3.5 equal to 14.4 mm, size 4 equal to 14.8 mm, and so on. Common ring sizes for women are 6 (16.5 mm), 6.5 (16.9 mm), and 7 (17.3 mm).
