What is the maximum length for a built-in dishwasher?

• A. 72 inches
• B. 78 inches
• C. 84 inches
• D. 90 inches

Answer: (B)

Built-in appliances have to fit inside a cabinet opening with enough room for installation, leveling, ventilation, and trim. The space available vertically for a dishwasher is determined by the height from the finished floor up to the bottom of the upper cabinets (or to the ceiling, depending on the layout). In many standard kitchen configurations, that vertical opening is around 78 inches, which is why 78 inches is considered the maximum length for a built-in dishwasher. Choosing a smaller opening (like 72 inches) can make room for the appliance but leave insufficient clearance for trimming and adjustment, while larger openings (84 or 90 inches) would require nonstandard cabinetry or ceilings and may not be practical in typical homes. Always verify with the appliance’s installation specs and the cabinet dimensions for your specific setup.
