What is my ring size?

I do not have a (similar) ring to determine my size

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

	circumference inside (in mm)	inner 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
