How to Calculate Gravel for Your Project
Calculating the right amount of gravel for your landscaping project is crucial for both budgeting and ensuring you have enough material to complete the job. Our free gravel calculator helps you estimate volume, weight, and cost with precision.
Understanding Gravel Measurements
Gravel is typically sold by the ton or by the cubic yard. One cubic yard of gravel covers approximately 100 square feet at 3 inches deep. The weight of gravel varies by type, with most gravel weighing between 2,800 to 3,400 pounds per cubic yard.
Quick Reference: Gravel Coverage
- 1 ton of gravel covers: ~100 sq ft at 2" depth
- 1 cubic yard covers: ~324 sq ft at 1" depth
- 50 lb bag covers: ~3 sq ft at 2" depth
- 10-ton truckload: ~1000 sq ft at 2" depth
Gravel Types and Their Best Uses
Different gravel types serve different purposes. Here's a quick guide to help you choose the right material for your project:
Pea Gravel
Small, rounded stones perfect for pathways, patios, and decorative landscaping. Not recommended for driveways due to shifting.
Density: ~1.78 tons/yd³
Crushed Stone
Angular edges lock together, making it ideal for driveways, base layers, and drainage projects. Most versatile option.
Density: ~1.60 tons/yd³
River Rock
Smooth, rounded stones in various sizes. Excellent for decorative features, dry creek beds, and erosion control.
Density: ~1.69 tons/yd³
Limestone
Light-colored stone ideal for pH-balancing soil. Popular for driveways and as a base for pavers and patios.
Density: ~1.54 tons/yd³
Why Order Extra Gravel?
We recommend adding 10-15% extra to your order to account for:
- Compaction during installation and settling over time
- Spillage during delivery and spreading
- Uneven ground surfaces requiring more depth in certain areas
- Future maintenance and top-ups
Our calculator includes a waste factor option that automatically adds this extra amount to your estimate.
