Where is drawing size and orientation saved

I'm having trouble getting my drawings to always default to the correct sheet size (A/letter, B/tabloid, etc) and orientation (Landscape or Portrait).  I've been playing with Sheet Formats and Drawing Templates, but with unpredictable results.  I currently have a bunch of different Sheet Formats to cover the range of sheet sizes, orientations, and units.  I only have 2 Drawing Templates (Inch and Metric).  Do I need to create more Drawing Templates to cover the different sheet sizes and orientations?SolidworksDrawings And Detailing
