Nominal Size

The labeled or named size of a cabinet, which may differ slightly from its actual measured dimensions. For example, a nominal 36-inch base cabinet may actually measure 35¾ inches wide to allow for reveals and fitting tolerances during installation. Understanding the difference between nominal and actual sizes is critical when planning cabinet layouts, especially in tight spaces where every fraction of an inch matters.
