How to Calculate Gravel Yardage

Gravel Volume Formula:

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

Gravel Volume (cu yd):

1. What is a Gravel Yardage 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 foundation bases.

2. How Does the Calculator Work?

The calculator uses the formula:

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

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 converts all measurements to feet, calculates cubic feet, then converts to cubic yards by dividing by 27.

3. Importance of Gravel Volume Calculation

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

4. Using the Calculator

Tips: Measure the length and width of your area in feet. Enter the desired depth in inches (converted automatically to feet). All values must be > 0.

5. Frequently Asked Questions (FAQ)

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

Q2: What's a typical gravel depth?
A: For driveways, 4-6 inches is common. For walkways, 2-3 inches may suffice.

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

Q4: Does this include compaction?
A: No, consider adding 10-20% more gravel to account for compaction.

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