FIGURE OUT USING VIRTUAL RING SIZER
Measure ring size with a virtual ring sizer-This technique requires you to print a virtual ring sizer. On this, ring sizes are represented in many circles that correspond to different sizes of rings.
After printing, place a ring (that already fits you) on the circle until you find the one that matches up with the inside circumference of your ring. When you have figured out the closest similar ring in the display with your ring, you only need to see the number under the ring.
