What is my ring size?

I don't have a (comparable) ring to determine my size

Measure your finger with a piece of string to determine the ring size. For a wide ring, take one size larger, as it will not only fit into the crease of your finger but also above it. (Rings may deviate from the size chart by a few tenths of a mm.)

	inside circumference (in mm)	inside diameter (in mm)
Size 5	48.8	15.4
Size 6	52	16.5
Size 7	54.5	17.3
Size 8	57	18
Size 9	59.8	18.9
