Please forgive my lack of knowledge as I usually size my images in pixels in Lightroom, but how large of a print can be made by an image sized 8in X 12in in photoshop - just that? An 8x12 printed image?
It all depends upon a subjective criteria...how many pixels per inch of print?
At 300 ppi, which most consider to be high res enough, 300*8 x 300*12 =2400 x 3600
At 200 ppi, which most consider to be acceptable, 200*8 x 200*12 = 1600 x 2400
Yes, someone COULD make a 16 x 20" print from 2400 x 3600, if they considered 150 pixels per inch to be acceptable quality for their needs! The ppi value is a DERIVED value and there is NOTHING inherent that prevents them from printing larger, nothing other than a commercial printer's insistance that a 300ppi file size to be supplied to them from the client for printing.
