What is the minimum kitchen counter depth?

• A. At least 22 in
• B. At least 24 in
• C. At least 26 in
• D. At least 28 in

Answer: (B)

In kitchen design, the standard working surface depth is 24 inches. This matches the depth of typical base cabinets, so a countertop sits on top to provide a practical prep area without crowding the room. A 24-inch depth gives enough space for food prep and small appliances while leaving room for plumbing and layout considerations behind the counter. Choosing less than 24 inches would make the prep area cramped and less functional, while deeper countertops (like 26 or 28 inches) require broader cabinets and more space, often complicating layout. So the minimum practical depth is 24 inches.
