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
