Measuring Fugi guides

Can anyone tell me where the measurement of a Fugi guide is made. I know the guides are measured in millimeters but is the number of the guide related to the inside diameter or outside diameter of the insert ring. :huh Specifically BNLG guides.

(I broke a couple :cry of the smaller guides, I believe they are size 10 and 8, but need to know which sizes to order)

    Outside diameter of the ring. or Inside diameter of the frame. That is the same measurement. Most if not all guide manufacturers follow this standard, although ID on rings do differ for different ring materials. EX. An alconite size 16 ring has a larger inner diameter than a 16 hardloy ring as the hardloy is a thicker ring.
