There are several different factors that can determine the best answer to your question, however, as a solid estimate, I would recommend 3500-4000 sq. inches. Stick closer to the lower end of the spectrum if you're a minimalist at all, but 4000 will give you plenty of room for comfortably hauling all of your equipment if you're not worried about weight as much.
