Gravel Coverage Formula:
Definition: This calculator estimates the area that 1 ton of gravel will cover based on its density and desired depth.
Purpose: It helps determine how much area can be covered with gravel for landscaping, driveways, or construction projects.
The calculator uses the formula:
Where:
Explanation: The formula calculates how many cubic feet are in 1 ton of gravel, then divides by depth to get square footage.
Details: Accurate coverage estimation ensures proper material ordering, cost control, and project planning.
Tips: Enter the gravel density (default 1.4 tons/cu yd) and desired depth in inches (default 2"). All values must be > 0.
Q1: What's a typical gravel density?
A: Most gravel weighs about 1.4 tons per cubic yard, but this can vary based on material type and moisture content.
Q2: How does depth affect coverage?
A: Coverage area decreases proportionally as depth increases. Double the depth = half the coverage area.
Q3: What depth should I use for different projects?
A: 2-3" for landscaping, 4-6" for driveways, 6-8" for heavy traffic areas.
Q4: Can I calculate for multiple tons?
A: Yes, simply multiply the result by your desired number of tons.
Q5: Does this include compaction factor?
A: No, consider adding 10-15% more material if significant compaction is expected.
