Steve, that will slightly vary by instrument when it comes out of the factory. Manufacturers set their action a little high so that folks can set the action a little lower to suit their individual preferences. A low action setup would be about 1/8" at the 12th fret. There really isn't any set amount but you don't want to go so low that you start experiencing buzzes. You might prefer a little higher action so the height at the 12th fret will be higher. I hope this helps.
