Standard Kitchen Dimensions in Inches: US Guidelines: A Data-Driven Guide to Optimizing Kitchen Layouts According to American Residential Standards

Kitchen dimensions in U.S. homes are driven by both ergonomic best practices and local building codes. According to the National Kitchen & Bath Association (NKBA), the average kitchen width is 120–150 inches (10–12.5 ft), while work aisles should be at least 42 inches wide for single-cook kitchens and 48 inches for multi-cook designs. Countertop depth typically measures 25 inches, and standard base cabinets are 24 inches deep with a height of 36 inches. For island installations, a minimum clearance of 36–42 inches around all sides is recommended to ensure safe movement and ADA compliance (source: NKBA Kitchen Planning Guidelines, 2023).
