What Is the Standard Width of a Kitchen Countertop?

In-stock and semicustom kitchen cabinets and countertops come in a few standard sizes, but custom options also are also available to create a functional kitchen that maximizes workspace. Kitchen islands tend to have more variable dimensions.


Standard Base Cabinets


The standard width of a kitchen countertop from the wall to the edge of the counter is 25 1/2 inches, though some are 25 5/16 inches. The standard allows for a 1 1/2-inch overhang over 24-inch-deep base cabinets. Standard laminate countertops are usually sold with a 3-inch backsplash attached, which doesn't affect the overall depth of the countertop but only leaves about 24 inches of worktop space.

Kitchen Islands


Kitchen islands and peninsulas can use standard 25 1/2-inch counters, but wider options are available. Standard 24-inch cabinets can support 27-inch and 36-inch countertops for more workspace. Extra-deep 48-inch island countertops are available, too, nearly doubling the standard countertop space.

Bar Tops


A bar top is another option that can be added on to a peninsula or island. A 42-inch-high bar or eating area can be added onto the back of a standard kitchen cabinet with a 15-inch, 18-inch or 21-inch top depending on your available space.
