It will depend on the size of the bale. Bales come in different sizes, but most will cover somewhere between 20 square feet to 120 square feet at about 2.5 to 3 inches deep. Ask that question when purchasing your bales since the size does vary considerably and some bales are machined compressed and some are hand compressed. For that reason, just looking at a bale and comparing the sizes does not always tell you how many square feet a particular bale will cover.
That really depends on the size and weight of the bale, as well as the depth of the cover. One large round bale of hay can be unrolled for at least 20 or 30 yards with a depth of 8 inches, where as a small square will only cover 5 square feet of area if all the flakes were put together in a square or rectangle.
