Ring Size
Is it very difficult for you to determine the accurate ring size?
Here, given below are various methods of determining the accurate size of your ring.
For accurate sizing, place a ring that fits you over the circle, making sure the inside of the ring lines up with the outside of the circle.
Another option is…
Print this page and cut out the ring sizer image provided here. Wrap the ring sizer around your finger with numbers facing out. When you have found a perfect fit, note the ring size number that appears at the end of the triangle.
The following chart shows conversion of local standard to the USA ring sizes.
Wrap a piece of string or a strip of paper around the finger, mark the ends and measure it against a ruler. Compare this with the length of a chart.
