About Granite Weight
Weight Factors
Granite weight depends on density, which typically ranges from 165-175 lbs/ft³. Thickness and dimensions dramatically affect total weight.
Transportation
Knowing the weight helps determine if professional installation is needed and what equipment will be required for transportation.
Structural Support
Heavy granite countertops may require additional cabinet reinforcement to ensure proper support and prevent sagging.
Granite Weight Calculator: Easily Determine Your Stone’s Weight
When planning a granite countertop, slab, or tile installation, knowing the exact weight is crucial for transportation, structural support, and installation. Our Granite Weight Calculator of Calculator Pro Tool simplifies this process, helping contractors, fabricators, and homeowners make informed decisions.
Why Calculate Granite Weight?
Granite is a dense, heavy natural stone, typically weighing 165–175 pounds per cubic foot (lbs/ft³). The weight varies based on:
✔ Thickness – Standard countertops (¾”) vs. thicker slabs (1¼”–3″)
✔ Dimensions – Larger pieces require proper support
✔ Density – Some granite types are heavier than others
Accurate weight calculations help with:
- Transportation planning – Ensures safe handling and proper equipment
- Cabinet reinforcement – Prevents sagging or damage
- Floor load capacity – Avoids structural issues
- Installation logistics – Determines if professional help is needed
How to Use the Granite Weight Calculator
Our calculator provides instant weight estimates in pounds (lbs) and tons. Simply enter:
- Dimensions (Length × Width × Thickness in inches)
- Granite Type (Standard, Light, or Dense)
- Quantity (Number of slabs or pieces)
Example Calculation:
A 72″ × 36″ × 1.25″ granite slab with standard density (170 lbs/ft³) weighs approximately 318 lbs.
Granite Weight Formula
The calculator uses this formula:
Weight (lbs) = (Length × Width × Thickness) / 1728 × Density × Quantity
- 1728 converts cubic inches to cubic feet
- Density varies by granite type (165–175 lbs/ft³)
Weight Comparison Guide

FAQs
1. How much does a granite countertop weigh per square foot?
- ¾” thick ≈ 12–13 lbs/ft²
- 1¼” thick ≈ 18–20 lbs/ft²
2. Can my cabinets support granite?
Most standard cabinets support 30–50 lbs/ft². If your granite exceeds this, reinforcement may be needed.
3. Do I need professional installation?
Pieces over 300 lbs typically require professional handling due to safety risks.
Conclusion
Our Granite Weight Calculator takes the guesswork out of planning your project. Whether you’re a contractor or a DIY enthusiast, knowing the exact weight ensures a smooth, safe installation.
📌 Pro Tip: Always verify structural support and use proper lifting equipment for heavy slabs!
