How to Calculate Gravel Coverage

Gravel Coverage Formula:

\[ A = \frac{V \times 27}{D} \]

Area Covered (sq ft):

1. What is Gravel Coverage Calculation?

Definition: This calculator determines the area that can be covered by a given volume of gravel at a specified depth.

Purpose: Helps in planning landscaping and construction projects by estimating how much area your gravel will cover.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ A = \frac{V \times 27}{D} \]

Where:

\( A \) — Area covered (square feet)
\( V \) — Volume of gravel (cubic yards)
\( 27 \) — Conversion factor (cubic feet per cubic yard)
\( D \) — Depth (feet)

Explanation: The formula converts cubic yards to cubic feet, then divides by depth to get coverage area.

3. Importance of Gravel Coverage Calculation

Details: Accurate coverage estimation ensures you purchase the right amount of gravel, preventing project delays or material waste.

4. Using the Calculator

Tips: Enter the gravel volume in cubic yards and desired depth in inches. The calculator converts depth to feet automatically.

5. Frequently Asked Questions (FAQ)

Q1: Why is 27 used in the formula?
A: There are 27 cubic feet in 1 cubic yard (3 feet × 3 feet × 3 feet).

Q2: What's a typical gravel depth for different applications?
A: Driveways: 4-6 inches, Walkways: 2-3 inches, Drainage: 6-12 inches, Decorative: 1-2 inches.

Q3: How do I convert cubic feet to cubic yards?
A: Divide cubic feet by 27 to get cubic yards.

Q4: Does this account for compaction?
A: No, consider adding 10-15% more gravel if significant compaction is expected.

Q5: How do I measure irregular areas?
A: Break into regular shapes (rectangles, circles), calculate each separately, then sum the areas.
