Plywood thickness for granite countertops.

Countertops that are 2cm thick usually are installed on a 3 8 plywood decking to increase its strength and resistance to weight. Granite and marble countertops that are 3cm thick are strong enough to support their own weight when installed on cabinet bases. Depending on thickness granite countertops may be self supporting without underlayment. 3cm material can go directly on top of the cabinets without the need for plywood support.

Although not technically plywood other engineered wood boards. It has also become the standard with granite because for a countertop more than 24 inches 2 centimeters granite would need a plywood base to fortify it atop the cabinets.
