Ring sizing can be tricky, but we have a chart to help get the proper ring size. Whole ring sizes will fit most everyone.
True diameter method
This is the method we use for our jewelry
The mark is read at the point at which the wider side of the taper meets the edge of the ring. Wide rings are occasionally tapered and the smaller of the edges of the ring should be taken as the true size since this is the diameter of the largest finger that can fit into it.
The easy method of measuring is to use a string or a piece of paper and wrap it around your finger and measure.
