>> If you're asking if the stated depth of a cabinet includes the doors/drawer fronts, the answer is no. Kitchen cabinet depths only account for the cabinet box. Doors & drawer fronts add about another inch.

So, a 24" deep cabinet is 26" when counting box + doors/drawer fronts.

Knobs/pulls add another 1" to 2", depending on your hardware.

Counter overhangs extend around 1.5" beyond the cabinet boxes.

>> If you're asking if you should include doors/drawer fronts when determining the depth of a cabinet, the answer is yes. In fact, you should also include the counter overhang if it has a counter.

What all this means, is that the depth of a run of cabinets with counters is usually 25.5" when accounting for cabinet boxes, doors/drawer fronts, and counter overhangs.
