👷 Safety First: Always adhere to local building codes and regulations. Wear appropriate Personal Protective Equipment (PPE) when performing construction tasks.
What is Gravel Volume Calculator?
Calculates the volume of aggregate material needed for landscaping or construction. Gravel is sold by volume (cubic yards) or weight (tons). This tool handles both, factoring in density.
How it Works
1. Calculate Volume: Length x Width x Depth.
2. Convert to Cubic Yards (Volume in cubic feet / 27).
3. Convert to Tons (Cubic Yards * 1.4 for standard gravel density).
4. Add Compaction Factor (~10-15%).
Step-by-Step Guide
- Measure Area – L x W of the coverage area.
- Depth – Thickness (e.g., 3 inches).
- Calculate – Get Cubic Yards and Tons.
- Compaction – Add extra for settling.
Example
Input: 20x20ft, 3in deep
Result: 3.7 Cubic Yards / 5.2 Tons
FAQ
How much does a yard of gravel weigh?
Approximately 2,800 lbs or 1.4 tons.
How deep should a driveway be?
Minimum 4-6 inches for vehicle support.
What is #57 stone?
Standard driveway gravel, roughly 3/4 inch size.
Cubic yard vs Ton?
Cubic yard is volume; Ton is weight. Trucks carry by weight.
Does rain affect weight?
Yes, wet gravel is heavier but volume remains similar.
Conclusion
Gravel compacts significantly. A 3-inch layer will settle to about 2.5 inches. Always order 10-15% more than the geometric volume to account for compaction and spreading loss.
