A gravel calculator is a construction and landscaping tool that helps you determine exactly how much gravel you need for any project. It calculates the volume of gravel required in cubic yards, cubic feet, and tons based on the area's dimensions and desired depth.
Whether you're building a driveway, creating a walkway, or landscaping a garden, knowing the right amount of gravel prevents both shortages and overspending. Ordering too little means delays and extra delivery fees. Ordering too much wastes money and leaves you with excess material.
The calculator also estimates cost based on gravel type, helping you budget for your project. This makes it an essential tool for homeowners, contractors, and landscapers planning gravel installations.
Calculating gravel volume involves three simple measurements. Here's the process:
Area (sq ft) = Length × Width
Cubic Feet = Area × (Depth ÷ 12)
Cubic Yards = Cubic Feet ÷ 27
Tons = Cubic Yards × 1.4 (average gravel weight)
Estimated Cost = Tons × Price Per Ton
20×10 foot driveway at 4 inches deep with crushed stone:
| Length | 20 feet |
| Width | 10 feet |
| Depth | 4 inches |
| Area | 200 sq ft |
| Cubic Feet | 66.67 |
| Cubic Yards | 2.47 |
| Tons | 3.46 |
| Estimated Cost ($25/ton) | $86.50 |
Different projects require different gravel depths. Using the correct depth ensures proper drainage, stability, and longevity.
Recommended depths by project:
Different gravel types serve different purposes and have varying costs:
| Gravel Type | Price/Ton | Best For |
|---|---|---|
| Crushed Stone | $15-$40 | Driveways, base layers |
| Pea Gravel | $30-$60 | Walkways, patios |
| Decorative Gravel | $50-$75 | Landscaping, gardens |
| River Rock | $40-$80 | Drainage, decoration |
| Limestone | $20-$45 | Driveways, construction |
Driveways are one of the most common gravel projects. A standard 2-car driveway (20×20 feet) needs approximately 10-15 cubic yards of gravel at 4-6 inches deep.
