Landscape Rock Coverage Calculator

Coverage Area Formula:

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

Coverage Area (sq ft):

1. What is a Landscape Rock Coverage Calculator?

Definition: This calculator estimates the area that can be covered with landscape rock based on the volume of rock available and the desired depth of coverage.

Purpose: It helps homeowners and landscapers determine how much area a given amount of rock will cover at a specified depth.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

\( A \) — Coverage area (square feet)
\( V \) — Volume of rock (cubic yards)
\( 27 \) — Conversion factor (cubic feet per cubic yard)
\( D \) — Depth of coverage (feet)

Explanation: The rock volume is converted to cubic feet, then divided by the desired depth (converted to feet) to determine coverage area.

3. Importance of Coverage Calculation

Details: Accurate coverage estimation ensures proper material ordering, cost control, and uniform appearance in landscaping projects.

4. Using the Calculator

Tips: Enter the rock volume in cubic yards and desired depth in inches (default 3 inches). All values must be > 0.

5. Frequently Asked Questions (FAQ)

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

Q2: What's a typical depth for landscape rock?
A: Common depths are 2-3 inches for decorative rock and 3-4 inches for functional applications like drainage.

Q3: How do I convert depth from inches to feet?
A: The calculator automatically converts inches to feet (dividing by 12) in the calculation.

Q4: How do I find the rock volume?
A: Use our Gravel Calculator or measure length × width × depth of your rock pile in feet, then divide by 27.

Q5: Does this account for compaction?
A: No, consider adding 10-15% more rock if significant compaction is expected.
