Ring Size enquiry form 1
Enter value in box then click outside box to activate.
We usually provide ring sizes in millimeters or fractions of an inch of diameter. Make sure you use the internal (int) diameter of the ring if given. Since ancient rings are not always made completely round we sometimes provide a measurement such as 16 x 18 mm int diameter. In this case take the average internal diameter (16+18)/2=17 and enter it in the converter to find the equivalent ring size.
