I used to rely on my old ring when I wanted to buy a new ring. I think it would not be much different. But actually my old size is different from my fingers’ size at that time. Surely this is also the case with you. Therefore, you will crave your ring size information as well you buy a ring directly in store both in your town and in online.
The standard ring gauge is a cigar. Each country has a ring gauge of each, but the ISO standard for ring size is ISO 8653:1986, it is define standard sizes in terms of the inner circumference of the ring measured in millimeters. Some countries have different standards of measurement in the ring. Information about the standards of different countries which I know is:
Several International Ring Sizers:
- UK, Europe
Standard ring size in the United States the same as in Canada, all sizes specified using a numerical scale of a quarter and half sizes, more specifically, in both regions the increase of a full size is an increase of 0.032 inches (0.8128 mm) in diameter, or roughly 1 / 10 inch (more precisely, 0.1005 in or 2.55 mm) in circumference inside. In three different regions, Ireland, the UK and Australia, ring measurements determined using alphabetical scale, with half sizes.
In three different regions in Asia, measuring ring set using a numerical scale, which only has a full-sized, and does not have a simple linear correlation with the diameter or circumference. This measurement is done in India, Japan and China. Meanwhile, in Austria, Germany, France, Scandinavia and Belgium, are very different from the above countries. In those five countries, sizes of rings specified using the actual internal circumference in mm (equivalent to ISO standards).
Another example of different measurements are also found in Italy, the Netherlands, Switzerland and Spain, which is defined as a circular size is reduced 40mm, with a 50 in Germany will be 10 in Switzerland. At least that bit of information I get, surely other countries also has their own standards, just not exposed by news.
