Each set of construction drawings uses a generic window and door sizing system that does not apply to any particular name brand. For example, a common window size on our plans is 4050. This is a window that is 4′-0″ wide by 5′-0″ tall. In like manner, a common door size is 2668, which means the door is 2′-6″ wide by 6′-8″ tall.
