Gravel Tonnage Calculator

$

Planning a landscaping or construction project? Whether you’re building a driveway, patio base, walkway, or drainage system, knowing how much gravel you need is essential. Ordering too little can delay your project, while ordering too much wastes money. That’s where our Gravel Tonnage Calculator comes in.

This easy-to-use online tool helps you quickly calculate:

  • Volume in cubic feet
  • Volume in cubic yards
  • Weight in tons
  • Estimated total cost

With just a few simple inputs, you’ll get accurate results in seconds — no manual math required.

Why You Need a Gravel Tonnage Calculator

Gravel is typically sold by the ton or by the cubic yard, depending on your supplier. Calculating gravel requirements manually can be confusing because:

  • Depth is often measured in inches
  • Length and width are measured in feet
  • Density varies depending on gravel type
  • Suppliers price material per ton

Our gravel calculator eliminates confusion by automatically converting measurements and applying density and cost formulas for you.

How the Gravel Calculator Works

The calculator uses the following inputs:

  1. Length (feet) – The length of the area you want to cover.
  2. Width (feet) – The width of the area.
  3. Depth (inches) – The thickness of gravel you plan to lay.
  4. Gravel Density (lbs per cubic foot) – Average density is 105 lbs/cubic ft (default value).

What the Tool Calculates

After entering your measurements and clicking Calculate, the tool provides:

  • Volume (Cubic Feet)
  • Volume (Cubic Yards)
  • Weight (Tons)
  • Estimated Cost (based on $45 per ton average)

Step-by-Step: How to Use the Gravel Tonnage Calculator

Using the calculator is simple:

Step 1: Enter the Length

Measure the area in feet and enter the length.

Step 2: Enter the Width

Measure the width in feet.

Step 3: Enter the Depth

Enter the depth in inches. Common depths include:

  • 2–3 inches for pathways
  • 4–6 inches for driveways
  • 8–12 inches for heavy load areas

Step 4: Enter Gravel Density

If you’re unsure, use the default value of 105 lbs per cubic foot, which works for most standard gravel.

Step 5: Click Calculate

Instantly view:

  • Total cubic feet
  • Cubic yards
  • Total tons required
  • Estimated cost

Step 6: Reset if Needed

Example Calculation

Let’s say you’re building a gravel driveway:

  • Length: 20 feet
  • Width: 12 feet
  • Depth: 4 inches
  • Density: 105 lbs/cubic foot

Calculation Results:

  1. Volume in Cubic Feet
    20 × 12 × (4 ÷ 12) = 80 cubic feet
  2. Volume in Cubic Yards
    80 ÷ 27 = 2.96 cubic yards
  3. Weight in Tons
    80 × 105 = 8,400 lbs
    8,400 ÷ 2,000 = 4.2 tons
  4. Estimated Cost
    4.2 × $45 = $189

This means you should order approximately 4.2 tons of gravel, costing around $189.

Common Gravel Densities

Different gravel types have slightly different densities. Here are average values:

  • Pea Gravel: 95–105 lbs/cubic ft
  • Crushed Stone: 100–110 lbs/cubic ft
  • River Rock: 95–110 lbs/cubic ft
  • Limestone Gravel: 100–110 lbs/cubic ft

If unsure, check with your supplier for exact density.
