1. What is a Gravel Yard Calculator?

Definition: This calculator estimates the volume of gravel needed based on the length, width, and depth of the area to be covered.

Purpose: It helps homeowners and construction professionals determine how much gravel is required for projects like driveways, walkways, or foundations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of gravel (cubic yards)
• \( L \) — Length of area (feet)
• \( W \) — Width of area (feet)
• \( D \) — Depth of area (feet)
• 27 — Conversion factor (cubic feet per cubic yard)

Explanation: The calculator first converts depth from inches to feet, then multiplies all three dimensions to get cubic feet, and finally divides by 27 to convert to cubic yards.

3. Importance of Gravel Volume Calculation

Details: Accurate gravel calculation ensures proper project planning, avoids material shortages or excess, and helps with budgeting.

4. Using the Calculator

Tips: Measure the length and width of your project area in feet. Enter the desired gravel depth in inches (typically 2-4 inches for walkways, 4-6 inches for driveways).

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 27?
A: There are 27 cubic feet in 1 cubic yard (3 feet × 3 feet × 3 feet). This converts the volume from cubic feet to cubic yards.

Q2: How do I measure irregularly shaped areas?
A: Break the area into rectangular sections, calculate each separately, then sum the volumes.

Q3: What's a typical gravel depth?
A: For driveways: 4-6 inches, for walkways: 2-4 inches, for drainage: 6-12 inches depending on application.

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

Q5: How many tons is a cubic yard of gravel?
A: Typically 1.2-1.4 tons per cubic yard, depending on gravel type and moisture content.
