If they don't, then 4 thick is usually standard for a patio slab, how large or small it is doesn't really matter. The most important part is the sub-base. Make sure you have a good gravel base. I would recommend at least 12 inches of compacted gravel. I like gravel where the aggregate (rocks) are no larger than 1.
A typical club-foot slab has 12 thick edges and the 12 thickness usually is installed with a 'rebar beam' structure around the perimeter, and is about 24-30 wide and then bevels in to the 6 thickness. The extra concrete carries the weight of the walls and structure. typical club-foot slab has 12 thick edges and the 12 thickness usually is installed with a 'rebar beam' structure around the perimeter, and is about 24-30 wide and then bevels in to the 6 thickness.
