1. What is a Gravel Yardage Calculator?

Definition: This calculator estimates the volume of gravel needed based on the area dimensions and desired depth.

Purpose: It helps homeowners and contractors determine how much gravel is required for projects like driveways, walkways, or drainage systems.

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 gravel (feet)
• 27 — Conversion factor (cubic feet per cubic yard)

Explanation: The calculator multiplies length × width × depth (converted to feet) then divides by 27 to convert cubic feet to cubic yards.

3. Importance of Accurate Gravel Calculation

Details: Proper calculation prevents over-ordering (wasting money) or under-ordering (delaying project completion).

4. Using the Calculator

Tips:

• Measure the area's length and width in feet
• Enter desired depth in inches (calculator converts to feet)
• For irregular areas, divide into rectangles and calculate separately

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).

Q2: What's a typical gravel depth?
A: For driveways: 4-6 inches, for walkways: 2-3 inches, 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% more gravel as it will compact over time.

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