Gravel by Yard Calculator Home Depot Installation

Gravel Volume Formula:

\[ V = \frac{L \times W \times D}{27} \]

Gravel Volume (cu yd):

Definition: This calculator estimates the volume of gravel needed based on project dimensions in feet and inches.

Purpose: It helps homeowners and contractors determine how much gravel is required for landscaping, driveways, and other projects.

The calculator uses the formula:

\[ V = \frac{L \times W \times D}{27} \]

Where:

Explanation: The calculator converts all measurements to feet, calculates cubic feet, then converts to cubic yards.

Details: Accurate gravel estimation ensures proper project completion, avoids material shortages, and prevents over-ordering.

Tips: Measure your project area carefully. For irregular shapes, divide into rectangles. Enter length and width in feet, depth in inches.

Q1: Why divide by 27?
A: There are 27 cubic feet in 1 cubic yard (3 feet × 3 feet × 3 feet).

Q2: What depth should I use?
A: For driveways use 4-6 inches, for walkways 2-3 inches, and for drainage 6-12 inches.

Q3: How do I measure irregular areas?
A: Break into rectangles, calculate each separately, then sum the volumes.

Q4: Should I add extra for compaction?
A: Yes, add 10-20% to your total volume to account for compaction.

Q5: How many bags equal a cubic yard?
A: Typically 54 bags (0.5 cu ft each) make 1 cubic yard.
