Can you determine ring size by diameter?
When measuring ring size, the diameter is the measurement across the inner width of the ring. To measure this, grab a tape measure or a ruler and measure the widest points of the inside of the ring – from edge to edge. If possible, try to use a circular ring for the most accurate reading of their ring size.
