A square bale of hay is usually 2 feet wide, 4 feet long, and 2 feet tall. A round bale of hay varies, depending on the baling equipment. The dimensions usually range from 4 ft x 4 ft to 4 ft x 6 ft. Edit: There are three sizes of square bales, small medium and large. Small bales are 2'x2'x4'.
A small square bale weighs from 40 to 100 pounds and large square bales weigh from 140 to 2000 pounds depending on how they were baled. So a 700 pound round bale could contain 17.5 small 40 pound bales or 5 of the 140 lb large squares.
