Gravel Calculator Guide
Understanding Gravel Measurements
Gravel is typically sold by volume (cubic yards or cubic meters) or by weight (tons or tonnes). This calculator helps you convert your project dimensions into the amount of gravel needed.
Key Factors:
- ⚖️Density
Different gravel types have different densities, affecting the weight per volume.
- 📏Depth
Proper depth is crucial for stability and drainage in your project.
- 🔄Compaction
Gravel will compact over time, reducing the effective depth.
- 💧Drainage
Larger gravel sizes provide better drainage for water management.
Recommended Gravel Depths
| Application | Recommended Depth | Notes |
|---|---|---|
| Walkways | 2-3 inches (5-7.5 cm) | Use smaller gravel for comfort |
| Driveways | 4-6 inches (10-15 cm) | Compact in layers for stability |
| Drainage Areas | 6-12 inches (15-30 cm) | Use larger gravel sizes |
| Landscaping | 2-3 inches (5-7.5 cm) | Decorative top layer |
| Patio Base | 4-6 inches (10-15 cm) | Use crushed stone for stability |
Gravel Coverage Guide
Here's approximately how much area 1 cubic yard (or 1 cubic meter) of gravel will cover at different depths:
Additional Considerations
- Landscape Fabric:
Consider installing landscape fabric beneath your gravel to prevent weed growth and keep the gravel from sinking into the soil.
- Edging:
Install edging around your gravel area to keep the material contained and maintain clean borders.
- Compaction:
For driveways and pathways, compact the gravel with a plate compactor for better stability and longevity.
- Drainage:
Ensure proper slope (about 1/4 inch per foot) away from buildings to prevent water pooling.
Frequently Asked Questions
Gravel typically costs between $30-$65 per cubic yard or $40-$85 per ton, depending on the type, quality, and your location. Decorative gravels can cost more, while basic crushed stone is usually less expensive.
A cubic yard of gravel covers approximately 100 square feet at 3 inches deep, 80 square feet at 4 inches deep, or 60 square feet at 6 inches deep. The coverage area depends on the depth of application.
A cubic yard of gravel typically weighs between 2,700-3,000 pounds (1.35-1.5 tons), depending on the type of gravel and its moisture content. Smaller, denser gravel will weigh more than larger, more porous types.
Different gravel types serve different purposes: Pea gravel (small, rounded stones) is decorative and good for walkways; Crushed stone provides stability for driveways and bases; River rock is larger and decorative; Drainage gravel has larger stones for water management applications.
To maintain a gravel surface: Rake regularly to keep it level; Add new gravel every 1-2 years to replace what's been lost; Control weeds with landscape fabric underneath and occasional herbicide; Regrade periodically to maintain proper drainage; Consider a binder for high-traffic areas to reduce dust and displacement.
