Calculate the Weight of Granite Slabs

Granite is a heavy material, and knowing the weight of a slab is critical for safe transportation, installation, and ensuring that the supporting structure (like cabinets for a countertop) can handle the load. Our Granite Weight Calculator makes this easy.

How It Works

The calculator determines the weight based on the slab's volume and the density of granite. You need to enter:

  • Length and Width: The dimensions of the granite slab. You can work in inches or centimeters.
  • Thickness: The thickness of the slab. Common thicknesses for countertops are 0.75 inches (2 cm) or 1.25 inches (3 cm).
  • Density: The calculator uses an average density for granite (around 165 lbs/ft³ or 2640 kg/m³). This can be adjusted if you know the density of the specific type of granite you are using.

    • The tool will provide you with the estimated weight of the slab in pounds (lbs), helping you and your installers prepare for a safe and successful project.
