Easily calculate how much gravel you need for your driveway. Our Gravel Driveway Calculator gives fast results in tons, yards, and cost estimates.
Planning a new gravel driveway? Or maybe you’re refreshing an old one? The biggest question is always the same. How much gravel do I need?
That’s why we built the Gravel Driveway Calculator. It saves time, avoids guesswork, and helps you plan your budget. With just a few numbers, you’ll know the volume, weight, and even truckloads of gravel required.
It’s easy to underestimate gravel needs. If you order too little, you’ll run short mid-project. If you order too much, you’ll waste money.
Our calculator removes the risk. You enter your driveway’s length, width, and depth. The tool does the math, giving results in cubic yards, cubic feet, tons, and even how many bags or truckloads you’ll need.
Think of it like a digital tape measure that also knows the weight of stone.
The math behind the calculator is simple. Here’s the step-by-step:
Step 1: Convert dimensions to feet
If your depth is in inches, divide by 12. Example: 3 inches ÷ 12 = 0.25 feet.
Step 2: Find volume in cubic feet
Formula:
Volume (ft³) = Length (ft) × Width (ft) × Depth (ft)
Step 3: Convert to cubic yards
Since 1 cubic yard = 27 cubic feet:
Volume (yd³) = Volume (ft³) ÷ 27
Step 4: Convert to weight (tons)
Gravel density is about 1.4 tons per cubic yard.
Weight (tons) = Volume (yd³) × 1.4
Step 5: Add waste factor
To allow for compaction or uneven ground, add 5–10%.
Order Volume = Volume × (1 + Waste %)
That’s it. The calculator applies this formula automatically.
Example: 1000 Foot Gravel Driveway
Let’s say your driveway is 1000 feet long and 10 feet wide. You want a depth of 3 inches.
So, you’ll need about 143 tons of gravel.
Not really. Two inches is fine for a walkway or light path. But a driveway needs strength. Most pros recommend at least 3–4 inches for cars. For heavy trucks, go deeper, around 6 inches.
One ton of gravel covers about 100 square feet at 2 inches deep. If you go 3 inches deep, it’ll cover closer to 80 square feet.
You’ll see results in cubic yards, tons, metric tons, bags, and truckloads.
It’s quick, simple, and accurate.
A gravel driveway adds charm, durability, and value to your home. But before you start, you need the right numbers. Our Gravel Driveway Calculator does the heavy lifting.
With it, you’ll know exactly how much gravel to order. No stress. No waste. Just the right amount of rock for a smooth, strong driveway.
It depends on gravel prices in your area. At $40 per ton, a 1000 foot driveway (about 143 tons) could cost around $5,700.
Use the formula: Length × Width × Depth, then convert to yards and tons. Or just use our calculator.
No. Go for at least 3–4 inches for cars, 6 inches for trucks.
About 100 square feet at 2 inches deep.
