Formula to Calculate Yards of Gravel Coverage

Gravel Coverage Formula:

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

Area Covered (sq ft):

1. What is the Gravel Coverage Calculator?

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

Purpose: It 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 of gravel (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 for pathways, driveways, or construction bases.

4. Using the Calculator

Tips: Enter the gravel volume in cubic yards and desired depth in feet. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 27 in the formula?
A: There are 27 cubic feet in 1 cubic yard, so we convert the volume to cubic feet before calculating coverage.

Q2: What's a typical gravel depth for different applications?
A: Driveways typically need 4-6 inches, pathways 2-3 inches, and drainage bases 8-12 inches.

Q3: How do I convert inches to feet for depth?
A: Divide inches by 12 (e.g., 6 inches = 0.5 feet).

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

Q5: How do I find the gravel volume if I know the weight?
A: Use our Gravel Calculator by Tons tool to convert weight to volume first.
