Ring size
The ISO standard for ring sizes is ISO 8653 : 2016 , which defines standard ring sizes in terms of the inner circumference of the ring measured in millimetres . In the United States and Canada , ring sizes are specified using a numerical scale , with quarter and half sizes . An increase of a full size is an increase of 0.032 inch ( 0.8128 mm ) in diameter , or roughly 1 / 10 inch ( more precisely , 0.1005 in or 2.55 mm ) in inside circumference . In Ireland , the United Kingdom and Australia , ring sizes are specified using an alphabetical scale , with half sizes . In India , Japan and China , ring sizes are specified using a numerical scale , that only has whole sizes , and does not have simple linear correlation with diameter or circumference . In Austria , France , Germany , Belgium and Scandinavia , ring sizes are specified using actual internal circumference in mm ( the same as the ISO standard ) . In some countries , half sizes may be used . In Italy , Spain , Netherlands , and Switzerland , ring sizes are specified as the circumference minus 40mm . A 50 in Germany will be a 10 in Switzerland .
