1. What is the Pea Shingle Coverage Calculator?

The Pea Shingle Coverage Calculator estimates the amount of pea shingle material needed for your project based on the area to be covered and desired depth. It helps prevent over- or under-ordering of materials.

2. How Does the Calculator Work?

The calculator uses the standard coverage formula:

Where:

• 324 — Conversion factor (accounts for square feet to square yards and inches to feet)
• Area — The surface area to be covered in square feet
• Depth — The desired depth of pea shingle in inches

Explanation: The formula converts your measurements into cubic yards, the standard unit for bulk material purchases.

3. Importance of Accurate Coverage Calculation

Details: Proper calculation ensures you purchase the right amount of materials, saving money and preventing project delays. Too little means multiple deliveries, while too much leads to wasted material and expense.

4. Using the Calculator

Tips: Measure your area accurately in square feet. For depth, typical pea shingle applications use 2-3 inches for landscaping and 4-6 inches for driveway applications.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between pea shingle and regular gravel?
A: Pea shingle consists of small, rounded stones (about 1/4" to 3/8" in size) that are comfortable to walk on, while regular gravel is larger and more angular.

Q2: How do I measure irregularly shaped areas?
A: Break the area into rectangles, calculate each separately, then sum the results. For circular areas, use πr² (3.14 × radius × radius).

Q3: Should I order extra material?
A: It's recommended to order 10-15% extra to account for compaction, settling, and measurement errors.

Q4: How much does a cubic yard of pea shingle cover?
A: One cubic yard covers about 100 sq ft at 3" depth, or 80 sq ft at 4" depth.

Q5: How do I convert cubic yards to tons?
A: Typically 1 cubic yard ≈ 1.25 tons, but check with your supplier as weight varies by material type and moisture content.
