Physical weathering is mechanical action which typically erodes rock faces. This invariably results in a smaller rock.
Chemical weathering involves water absorption or other reactions. Mechanical heating and freezing can crack and fissure the rock, slightly increasing its size. In general, physical weathering is an abrading process, whether via water born sediment wearing away the rock, or wind blown particles sand blasting the rock, and these actions make reduce the rock's size.
