The weight of a granite slab depends on its dimensions and thickness. Here’s a breakdown:

General Weight Calculation for Granite:
Granite weighs approximately 18–20 pounds per square foot for a 1-inch (2.54 cm) thick slab.
Thicker slabs (e.g., 2 cm or 3 cm) will weigh more, typically:
2 cm thick slab: ~12 pounds per square foot.
3 cm thick slab: ~18–20 pounds per square foot.

Example Weights:
Standard Slab Dimensions:
8 feet x 4 feet (96 inches x 48 inches) at 3 cm thickness:
Area: 32 square feet.
Weight: ~576–640 pounds (32 sq. ft. × 18–20 lbs/sq. ft.).

Smaller Cut Pieces:
2 feet x 2 feet (24 inches x 24 inches) at 3 cm thickness:
Area: 4 square feet.
Weight: ~72–80 pounds.

Factors Affecting Weight:
Granite Density: Some types of granite are denser than others, slightly increasing the weight.
Surface Finish: Polished surfaces may add minimal additional weight.

If you’re planning to install granite, it’s essential to account for this weight to ensure adequate structural support, especially for countertops or wall applications. Would you like advice on handling or transporting granite slabs?
