How much storage area is required for hay?

Baled hay requires approximately 250 cubic feet of storage space per ton of hay. An 1,100-pound horse eating 1.5 percent to 2.0 percent of its body weight per day in hay would eat 16.5 to 22.0 pounds per day, or in one year about 3 to 4 tons (100-120 bales of hay). Four tons of hay require 1,000 cubic feet of space or a storage area roughly 9 feet high and 11 feet x 11 feet (9′ x 11′ x 11′). In other words, a horse fed hay all year would require roughly an area the size of a box stall to store one year’s supply of hay.
