Mandrels for sizing
If using a Mandrel, we suggest deducting ¼ or even a ½ number smaller in a US size or 1 full letter in Australian/UK sizes.
A mandrel has a hard round metal surface. It will not measure any irregular shapes, square or a flat edges, on a hard metal ring accurately. Adding to this, inexpensive mandrels are often not calibrated 100% correctly.
A mandrel is not 100% accurate, use it as an approximate guide only!
