Gravel Driveway Calculator
Calculate how much gravel you need for your driveway construction project
Driveway Dimensions
Length of the driveway from start to end
Width of the driveway (typically 3-4 meters for single car, 6-7 meters for double car)
Recommended depth: 10-15 cm (4-6 inches) for standard driveways, 15-20 cm (6-8 inches) for heavy vehicles
Standard gravel density: 1.25 tonnes/m³ (varies by gravel type: 1.2-1.7 tonnes/m³)
Gravel Requirements
Formula: Volume = 0.0m × 0.0m × 0.000m = 0.000 m³
Weight: 0.000 m³ × 1.25 tonnes/m³ = 0.00 tonnes
Cost Estimation (Optional)
Example Calculation
Omnicalculator Example
Dimensions: 100m length × 3m width × 15cm depth
Area: 100 × 3 = 300 m²
Depth conversion: 15cm = 0.15 meters
Volume: 100 × 3 × 0.15 = 45 m³
Weight & Cost Calculations
Weight: 45 m³ × 1.25 tonnes/m³ = 56.25 tonnes
Cost: 45 m³ × $20/m³ = $900
Total needed: 45 cubic meters (56.25 tonnes)
Gravel Types
Pea Gravel
Small, rounded stones. Good for decorative driveways.
Size: 1/4" - 1/2"
Crushed Stone
Angular stones that compact well. Best for stability.
Size: 1/2" - 1"
Decomposed Granite
Fine granite particles. Compacts to hard surface.
Size: Fine to 1/4"
River Rock
Smooth, rounded stones. Decorative but less stable.
Size: 1" - 3"
Depth Guidelines
Installation Tips
Prepare base with proper drainage
Use landscape fabric to prevent weeds
Compact each layer during installation
Add 10% extra material for compaction
Ensure proper slope for water runoff
Install edging to maintain shape
Understanding Gravel Driveway Calculations
What is a Gravel Driveway?
A gravel driveway is a cost-effective alternative to paved surfaces, made from loose rocks, sand, and clay mixture. This type of driveway is popular in rural areas and provides excellent drainage while being environmentally friendly.
Why Choose Gravel?
- •Lower cost than paved alternatives
- •Excellent drainage properties
- •Easy to repair and maintain
- •Environmentally friendly option
Calculation Formulas
Volume: Length × Width × Depth
Weight: Volume × Density
Cost: Volume × Price per Unit
- Standard Density: 1.25 tonnes per cubic meter
- Typical Depth: 10-20 cm (4-8 inches)
- Cost Range: $15-40 per cubic meter
- Coverage: 1 m³ covers ~100 m² at 1cm depth
Pro Tip: Order 10-15% extra gravel to account for compaction and future maintenance needs.
