Ideal size hay barn for 3x4x8 bales

I am trying to design the best size building for big square. I have been in the small square business for 20 years and have buildings 40x100x 20 ft tall built for my SP wagons. I am thinking for big square I need it 80 to 100 ft wide by 150 to 200 long. Please give me your option. I am thinking of building a 100x200x20 or two 80x100x20. I have bought 2 MF 2270 HD's an a Pro Ag stacker. I am thinking about adding mil stacks to my BW 38's.
