Gravel Tonnage Calculator

Need gravel for your project but don’t know how much to buy? Whether you’re building a driveway, laying a walkway, or filling a garden bed, guessing won’t help. That’s why we built a simple Gravel Tonnage Calculator. It takes your measurements and gives you the exact amount of gravel you’ll need.

No math headaches. No wasted money. Just fast, accurate results.

What Is a Gravel Tonnage Calculator?

It’s a tool that helps you figure out how many tons (or tonnes) of gravel you’ll need based on your project's length, width, and depth. You enter your values, pick a gravel type or enter your own density, and it does the rest.

Our calculator supports both Imperial (feet, tons) and Metric (meters, tonnes) systems.

How Do You Calculate Gravel Tonnage?

Here’s the simple formula we use:

For Imperial (feet):

volume = length × width × depth

volume in cubic yards = volume ÷ 27

tonnage = volume in cubic yards × gravel density

For Metric (meters):

volume = length × width × depth

tonnage = volume × gravel density

Most standard gravel weighs between 1.4 to 1.7 tons per cubic yard, or 1.68 tonnes per cubic meter.

How Far Will 1 Ton of Gravel Cover?

That depends on the depth:

• At 2 inches deep, 1 ton covers about 100 square feet.
• At 4 inches deep, it covers about 50 square feet.

Want exact coverage? Use our calculator. It handles the math for you.

How Many Tons of Gravel for a 100 ft Driveway?

Let’s say your driveway is:

• Length: 100 feet
• Width: 10 feet
• Depth: 0.5 feet (6 inches)
• Density: 1.55 tons per cubic yard

Here's the quick math:

Volume = 100 × 10 × 0.5 = 500 cubic feet  

Cubic Yards = 500 ÷ 27 ≈ 18.52  

Tonnage = 18.52 × 1.55 ≈ 28.7 tons

So, you’ll need about 29 tons of gravel.

How Much Is 1 Ton of Gravel?

The cost depends on your location and gravel type. But on average:

• Standard gravel costs between $25 to $50 per ton.
• Decorative or specialty gravel may cost more.

Always check local prices before ordering.

FAQs

How do you calculate gravel tonnage manually?

Multiply length × width × depth. Convert to cubic yards or meters. Then multiply by gravel density.

What’s the average gravel density?

For Imperial: 1.4 to 1.7 tons per cubic yard

For Metric: 1.68 tonnes per cubic meter

Can I use this calculator for crushed stone?

Yes! Just select the correct density for crushed stone, or enter a custom one.

What’s a good depth for driveways?

About 4 to 6 inches (0.33 to 0.5 feet) is standard for gravel driveways.

Is this calculator mobile-friendly?

Yes! It works on all devices phones, tablets, or desktops.
