Stone and Gravel Calculator
Calculate combined amounts of stone and gravel for mixed projects.
Quick Answer
To calculate stone and gravel, multiply length × width × depth in feet, divide by 27 for cubic yards, then multiply by about 1.4–1.5 for tons. A 10 × 10 ft area at 3 inches deep needs roughly 0.9 cubic yards (about 1.3 tons).
Stone and Gravel Calculator - Estimate Tonnage & Cubic Yards Guide
The stone and gravel calculator is a professional-grade tool for estimating aggregate material quantities for complex landscaping and construction projects. Whether you are layering #57 crushed stone for a driveway sub-base or estimating decorative pea gravel for a garden path, this calculator provides precise tonnage and cubic yard requirements.
Many projects require a combination of materials, such as a structural layer of crushed stone for stability and a top dressing of gravel for aesthetics. By calculating these simultaneously, you can optimize your bulk delivery and reduce waste. This is especially useful for French drains, retaining wall backfill, and mixed-material driveway construction.
Our tool handles various material densities—from dense crusher run to lightweight volcanic rock—ensuring your weight estimates (tons) are as accurate as your volume estimates (yards). To learn more about selecting the right material, check our guide on crushed stone vs. pea gravel.
Move and Spread Your Stone Without the Backache
Ordering the right amount is half the battle; placing it is the other half. A bow rake is the fastest way to spread stone and gravel to an even depth and knock down high spots, and its flat back doubles as a screed for a tidy finish. And since most loads land in one pile on the driveway, a sturdy contractor wheelbarrow saves you dozens of trips moving it to where it actually needs to go — a small purchase that pays for itself on the first project.

Frequently Asked Questions
When would I need both stone and gravel?
Common applications include: driveways (stone base with gravel surface), drainage systems (different stone sizes for optimal flow), multi-layer installations (stone base, gravel middle layer, decorative top), and projects with varying material requirements across different sections.
What's the difference between stone and gravel?
Stone typically refers to larger, angular crushed materials (3/4 inch to 2 inches) used for base layers and structural support. Gravel refers to smaller, often rounded materials (pea gravel, river rock) used for surface applications, drainage, and decorative purposes. Both are aggregates but serve different functions.
How do I calculate quantities for layered applications?
Calculate each layer separately using its specific depth and area. For example, a 6-inch stone base layer and a 2-inch gravel surface layer would be calculated separately, then combined for total material needs. Our calculator can handle these multi-layer calculations.
Can I use this for projects with mixed materials in the same layer?
Yes, if you're mixing stone and gravel in the same application, calculate the total volume needed, then determine the percentage of each material. The calculator helps you plan material ratios and quantities for mixed applications.
How do densities differ between stone and gravel?
Crushed stone is typically denser (1.4-1.5 tons per cubic yard) than rounded gravel (1.2-1.3 tons per cubic yard) due to better compaction and less void space. The calculator accounts for these density differences in weight calculations.
Should I order stone and gravel separately?
Yes, typically order materials separately since they serve different purposes and may come from different suppliers or stockpiles. The calculator provides separate quantity estimates for each material, making it easier to place accurate orders with suppliers.
