What Is a Gravel Calculator?
A gravel calculator is an online or manual tool that estimates the amount of gravel needed based on:
- Area dimensions (length, width, depth)
- Type of gravel (crushed stone, pea gravel, etc.)
- Compaction and settling factors
Using a gravel calculator ensures you purchase the right amount, saving time and money.
Types of Gravel & Their Uses
Different projects require different types of gravel. Here are the most common ones:
1. Crushed Stone
Best for: Driveways, base layers, drainage
Size: ¾ inch to 2 inches
Pros: Durable, excellent compaction
2. Pea Gravel
Best for: Landscaping, pathways, playgrounds
Size: ⅜ inch rounded stones
Pros: Smooth texture, aesthetically pleasing
3. Decomposed Granite
Best for: Patios, walkways, garden beds
Pros: Natural look, good drainage
4. River Rock
Best for: Decorative landscaping, drainage ditches
Pros: Weather-resistant, erosion control
How to Calculate Gravel Needed (Step-by-Step)
Follow these steps to manually calculate gravel quantity:
Step 1: Measure the Area
Length (ft) × Width (ft) = Square Footage
Example: 10 ft × 15 ft = 150 sq ft
Step 2: Determine Depth
- For driveways: 3-4 inches
- For pathways: 2-3 inches
Convert inches to feet (e.g., 3 inches = 0.25 ft)
Step 3: Calculate Cubic Yards
Formula: (Square Footage × Depth in Feet) ÷ 27 = Cubic Yards
Example: (150 sq ft × 0.25 ft) ÷ 27 ≈ 1.4 cubic yards
Step 4: Adjust for Compaction & Waste
Add 10-15% extra for settling and spillage.
Example: 1.4 cubic yards + 15% = 1.6 cubic yards
Gravel Cost Estimation
Gravel prices vary based on type and location. Average costs:
- Crushed Stone: $25 - $50 per ton
- Pea Gravel: $30 - $55 per ton
- Delivery Fees: $50 - $150 per load
Pro Tip: Buying in bulk (by the ton) is cheaper than per bag.
FAQs About Gravel Calculation
1. How much gravel do I need for a 12x12 patio?
At 3-inch depth: (12 × 12 × 0.25) ÷ 27 ≈ 1.33 cubic yards
2. Can I use a gravel calculator for drainage projects?
Yes, but ensure you choose the right type (e.g., crushed stone for better drainage).
3. How deep should a gravel driveway be?
- Base layer: 4-6 inches of crushed stone
- Top layer: 2-3 inches of finer gravel
