The weight of a granite countertop is a crucial factor in its installation and overall support requirements. A typical granite slab, commonly used for countertops, is about 1.25 inches (3 centimeters) thick. On average, granite weighs approximately 13 pounds per square foot at this thickness. Therefore, a ten-square-foot section would weigh around 130 pounds. This weight can vary based on the specific type of granite, its density, and thickness.
Understanding the anticipated weight is essential for several reasons. Proper structural support is paramount to prevent countertop collapse or damage to underlying cabinetry. This knowledge informs decisions about cabinet construction, bracing, and installation methods. Historically, less dense materials like laminate were common countertop choices. The shift towards heavier materials like granite and engineered stone has necessitated greater attention to weight-bearing capacity in kitchen design and renovation.
