Sistem

There are several systems to show the size of jewelry rings that are used all over the world:

• The ISO standard for ring size is ISO 8653: 2016, which defines the standard ring size in terms of the inner circumference of a ring measured in millimeters.
• In the United States and Canada, ring sizes are determined using a numerical scale, with a quarter and a half size. The full-size increase is an increase of 0.032 inches (0.8128 mm) in diameter, or about 1/10 inches (more precisely, 0.1005 in or 2.55 mm) inside the circumference.
• In Ireland, the UK, and Australia, ring sizes are determined using an alphabetical scale, half the size.
• In India, Japan, and China, ring sizes are determined using numerical scales, which have only the overall size, and do not have simple linear correlations with diameter or circumference.
• In Austria, France, Germany, Belgium and Scandinavia, ring sizes are determined using actual internal circumference in mm (same as ISO standards). In some countries, half the size can be used.
• In Italy, Spain, Netherlands, and Switzerland, ring sizes are set as minus 40mm. A 50 in Germany will be 10 in Switzerland.

For systems applicable in the United States, the Circular of the Bureau of Standards summarizes the situation as: "Although there seems to be only one standard used in the United States, in fact, due to a lack of certain dimensions and due to errors introduced by the adoption of general commercial articles as patterns, there are many, albeit similar, standards. "There seems to be no standard upgrades since then.

Bagan

The size of the ring can be measured physically with a plastic or metal ring sizer, or by measuring the inner diameter of the corresponding ring. There are also online gauges available. Online gauges vary, but many offer several ways to measure ring sizes, such as wrapping pieces of paper around a finger, or measuring current rings according to the chart.
