4" thick but use at least 4" of gravel underneath.

18 inches. Use a "grade beam" foundation. Thats what I did. What it is, is a slab with the outside edges poured thicker. On my garage theres a 12 inch wide by 18 inch deep beam to keep the slab under the frost line, and to keep the pad from bending and cracking.
This method is a whole lot cheaper than putting in anything else, and gives you a solid start. Also get fiber mesh mixed in your concrete. All it is, is little strings of fiberglass that make the concrete just as strong as putting in re-bar, and mesh. I had that done, AND re-bar with mesh. A little overboard but for the cost its well worth it.

FIND OUT HOW DEEP THE FROST LINE IS THEN YOU HAVE TO BE BELOW THAT. CONTACT THE BUILDING DEPARTMENT AND THEY CAN GIVE YOU ALL THE INFO THAT YOU NEED,
