Landscape Rock Coverage Calculator per Yard

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 depth (converted to feet) to determine coverage area.

3. Importance of Coverage Calculation

Details: Accurate coverage estimation ensures proper material ordering, avoids project delays, and helps with budget planning.

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 (3 feet × 3 feet × 3 feet).

Q2: What's a typical depth for landscape rock?
A: Common depths are 2-4 inches for decorative rock and 3-6 inches for pathways.

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

Q4: Does this account for compaction?
A: No, for compaction consider adding 10-15% more material to your calculation.

Q5: How do I measure my area to calculate needed volume?
A: Measure length × width × desired depth (in feet) then divide by 27 to get cubic yards.
