About Gravel Calculator

Our Gravel Calculator helps you estimate the amount of gravel needed for your driveway, path, landscaping, or construction project. By calculating the volume based on area and depth, and accounting for gravel density, this tool provides accurate measurements to help you purchase the right amount of materials.

How to Use

1. Choose between entering total area or dimensions (length and width)
2. Specify the desired depth of the gravel layer
3. Select the type of gravel or enter a custom density
4. Optionally, add pricing information to calculate total cost
5. Click "Calculate" to get the results

Recommended Gravel Depth

The ideal depth of gravel depends on its application:

• Pathways and walkways: 2-3 inches (5-7.5 cm)
• Driveways: 4-6 inches (10-15 cm)
• Landscaping and garden beds: 2-3 inches (5-7.5 cm)
• Construction and drainage: 6-12 inches (15-30 cm)

Types of Gravel

There are many types of gravel available, each with its own characteristics:

• Crushed Stone: Angular pieces of rock that lock together for stability
• Pea Gravel: Small, rounded stones that are comfortable to walk on
• River Rock: Smooth, rounded stones from riverbeds
• Decomposed Granite: Fine particles that compact well
• Marble Chips: White or colored chips for decorative use

Gravel Density

Density varies by type and size of gravel. Our calculator uses standard densities:

• Gravel (0.2-2"): 1.4 tons/cubic yard
• Gravel with sand: 1.5 tons/cubic yard
• Dry sand: 1.3 tons/cubic yard
• Wet sand: 1.6 tons/cubic yard

Benefits of Gravel

• Drainage: Allows water to percolate through, reducing runoff
• Durability: Long-lasting and requires minimal maintenance
• Versatility: Suitable for many applications from driveways to gardens
• Cost-effective: Generally less expensive than paved surfaces
• Eco-friendly: Permeable surface helps recharge groundwater

Gravel Installation Tips

• Prepare a solid base by excavating and compacting the soil
• Use landscape fabric to prevent weed growth
• Install edging to keep gravel in place
• Consider using different sizes for better compaction
• Periodically rake and top up gravel as needed
