1. What is the River Stone Calculation?

The River Stone calculation determines how many tons of river rock are needed to cover a specific area at a desired depth, accounting for the material's density.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• Length — Area length in feet
• Width — Area width in feet
• Depth — Desired depth in inches
• Density — River stone density (typically 1.4-1.6 tons per cubic yard)

Explanation: The calculation first converts all measurements to yards, calculates cubic yards needed, then converts to tons based on material density.

3. Importance of Accurate Calculation

Details: Proper calculation ensures you order the correct amount of material - too little leaves your project incomplete, while too much wastes money and creates disposal issues.

4. Using the Calculator

Tips: Measure your area carefully in feet. Typical depth for river rock applications is 2-4 inches. Density varies by stone size and type - consult your supplier for exact values.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density for river stone?
A: River stone density typically ranges from 1.4 to 1.6 tons per cubic yard, depending on stone size and composition.

Q2: How deep should I lay river stone?
A: For decorative purposes, 2-3 inches is common. For functional applications like drainage, 4+ inches may be needed.

Q3: Should I account for compaction?
A: Yes, consider adding 10-20% extra material to account for settling and compaction over time.

Q4: How do I measure irregular areas?
A: Break the area into rectangular sections, calculate each separately, then sum the totals.

Q5: What's the coverage per ton?
A: Coverage varies by depth. At 2" depth, one ton typically covers about 80-100 square feet.
