Crushed Stone Base Calculator
Calculate how much crushed stone you need for your construction project with our comprehensive calculator. Determine optimal quantities based on area dimensions, depth requirements, and stone type specifications.
Step 1: Project Dimensions
Understanding Depth Requirements
Typical crushed stone base depths range from 2-4 inches for walkways, 4-6 inches for driveways, and 6-12 inches for heavy-duty applications. Always consult local building codes for specific requirements.
Step 2: Material Specifications
About Compaction Factor
Compaction factor accounts for material settling and compression after installation. Typically 15-25% additional material is needed to achieve the desired compacted depth after installation and settling.

Material Calculation Breakdown
Calculation Formula
Material (tons) = (Length × Width × (Depth/12)) / 27 × Density × (1 + Compaction%)
To calculate material needed: Multiply length by width by depth (converted to feet), divide by 27 to get cubic yards, multiply by stone density, then add compaction factor percentage.
