Feeding raw, when are pork bones too big?

I know you aren't supposed to feed weight bearing bones, but I'm also not entirely sure what that means, When are pork bones too big and risk chipping teeth?

Ps: wondering cause I got bigger than usually cuts of pork and am eyeing the bone like to give? or not to give? that is the question.

I don't think it's the size of the bone really, but what type of bone it is. A weight bearing bone (leg bone) is going to be denser/harder than eg a rib bone, neck bone, tail bone, etc. so more likely to chip teeth.
