Find Your Ring Size At CaratBee
To measure your ring size, you can wrap a strip of paper or piece of string around your finger, mark where it overlaps, unwrap it, and measure its length along a ruler or tape measure. Place an existing ring over a circular ring sizing chart or use a ring sizer to determine your size.
