Crushed Stone Calculator
Calculate the precise volume and weight of crushed stone needed.
Crushed Stone Calculator - Calculate Volume, Weight & Cost for Your Project
Our Crushed Stone Calculator helps you determine the exact amount of crushed stone needed for driveways, pathways, drainage projects, and construction bases. Crushed stone is one of the most versatile materials in landscaping and construction, offering excellent drainage and a stable foundation for various applications.
Whether you're building a gravel driveway, creating a paver base, or installing a French drain system, this calculator provides accurate volume estimates in cubic yards and tonnage to help you order the right amount from suppliers.
Frequently Asked Questions
How much crushed stone do I need per square foot?
For a 2-inch depth, you need approximately 0.006 cubic yards per square foot. For a 4-inch depth (common for driveways), you need about 0.012 cubic yards per square foot. Our calculator automatically computes this based on your dimensions.
What size crushed stone is best for driveways?
#57 stone (3/4 inch) is the most popular choice for driveway surfaces. For the base layer, #2 stone (2-3 inches) provides excellent drainage and stability. Many driveways use a layered approach with larger stones at the bottom.
How much does a cubic yard of crushed stone weigh?
Crushed stone typically weighs between 2,500-2,800 pounds (1.25-1.4 tons) per cubic yard, depending on the stone type and moisture content. Granite is heavier than limestone. Use our tonnage calculator for precise weight conversions.
How deep should crushed stone be for a driveway?
A residential driveway typically needs 4-6 inches of crushed stone. This usually consists of a 4-inch base layer of larger stone (#2) topped with 2 inches of smaller stone (#57) for the driving surface.
What's the difference between crushed stone and gravel?
Crushed stone is mechanically broken rock with angular edges that lock together for stability. Gravel consists of naturally weathered, rounded stones. Crushed stone is better for bases and driveways due to its interlocking properties.
