Ever ordered gravel and ended up with half a pile sitting in your yard for months, or worse, ran short mid-project? I’ve been there. Getting the amount right sounds simple, but a small mistake in depth or area can cost you a second delivery fee. That’s exactly why a gravel calculator exists: to take the guesswork out and give you a clear number before you spend a single dollar.
A gravel calculator is a simple online tool that tells you how much gravel you need for a project. You just put in the length, width, and depth of the area, and it gives you the amount in cubic yards, cubic feet, or tons.
It can also estimate the cost if you enter the price per unit. No math stress, no guessing.
Buying too much gravel wastes your money. Buying too little means a second trip or another delivery charge. A gravel estimator gives you a real number so you order just what you need, plus a little overage for safety.
Anyone doing a home project, a driveway, garden path, patio base, drainage fix, or even a backyard makeover. You don’t need to be a contractor. If you can measure length and width, you can use this tool.

Using this calculator is very simple. Just follow these steps one by one, and you will get your answer in seconds.
| 1 | Choose Your Area Shape Click one of the three shape buttons at the top — Use Total Area, Rectangle, or Circle. If your area is a rectangle or square, pick Rectangle and enter the Length and Width. If it is a round area like a circular garden, pick Circle and enter the Diameter. If you already know the total size of your space, just pick Use Total Area and type the number directly. |
|
| 2 | Enter Your Measurements Type in the size of your area based on the shape you picked. For Rectangle, enter the Length and Width. For Circle, enter the Diameter. For Total Area, enter the square size. Then enter the Depth of Gravel — how thick you want the gravel layer to be. You can freely mix units — inches, feet, yards, cm, or meters — just select the right unit next to each number box. |
|
| 3 | Select Your Gravel Density Use the Gravel Density dropdown to tell the calculator what type of material you are using. Options include standard Gravel, Gravel with Sand, Dry Sand, and Wet Sand. If you know the exact density of your material, choose Use Your Own Density and type the number in the box that appears. This step affects the weight result, so pick the closest match to your material. |
|
| 4 | Add Optional Price. If you want to know the total cost, type the price per unit in the Price field. Then choose how your supplier charges — per cubic yard, per cubic foot, per kg, per short ton, per metric ton, per liter, or per bag. If you leave this blank, the calculator will still show you the full volume and weight — just without the cost estimate. | |
| 5 | Click Calculate Hit the big orange Calculate button, and your results appear instantly. You will see the Total Volume in Liters, Cubic Meters, Cubic Yards, and Cubic Feet — all at once. You will also see the Approximate Weight in kg, metric tons, pounds, and short tons. If you entered a price, the Estimated Cost shows up too. |
|
| 6 | Save or Share Your Results After calculating, three action buttons appear below the results. Click Copy Results to copy the numbers as plain text. Click Download PDF to get a clean, professional report saved to your device. Click Share Calculation to send the results directly from your phone or copy the link to your clipboard. |
|
| 7 | Clear and Recalculate To start over, click the ✕ Clear button. This resets all fields and removes the results so you can enter a completely new set of measurements from scratch. |
This is the question everyone has. Honestly, once you understand the basic formula, it becomes second nature. I use it every time I plan a project in my yard.
Most gravel suppliers sell by the ton, not by the cubic yard. So you need one more step. Most standard crushed stone and pea gravel weigh about 1.4 tons per cubic yard. Heavier stones like river rock can reach 1.5 to 1.6 tons per yard.
According to the Federal Highway Administration (FHWA), proper gravel quantity planning is key to road and path stability, and this same principle applies to home projects, too.
The depth you choose makes a huge difference to your final number. I once planned a garden path and forgot to double-check the depth. I ended up ordering twice as much as I needed. Lesson learned.
Here is a simple depth guide by project type:
| Application | Thickness | Notes | Waste Buffer |
|---|---|---|---|
| Driveway (light traffic) | 4 inches | For cars and small vehicles | +10% |
| Driveway (heavy traffic) | 6 inches | For trucks and frequent use | +10% |
| Walkway or path | 2 to 3 inches | Foot traffic only | +10% |
| Patio base | 4 to 6 inches | Needs structural support | +10% |
| Garden or landscaping | 2 to 2.5 inches | Decorative or mulch replacement | +10% |
| French drain | 6 to 12 inches | Drainage needs vary by soil conditions | +15% |
A small change in depth changes your total order a lot. Going from 2 inches to 4 inches doubles your material. That’s why it’s so important to decide on depth before you calculate — not after.
For driveways, deeper is better. Compaction can reduce volume by up to 30% over time, especially in high-traffic areas. Plan for that from the start.
Not all gravel is the same. This is where a lot of people get confused. I’ve seen folks buy smooth decorative pebbles for a driveway, and end up with a surface that shifts every time a car moves. Here’s a simple breakdown.
This is the step most people skip, and then regret. When gravel is transported, some always spills off the truck or wheelbarrow. And once laid, it compacts and settles, especially in the first few weeks.
For orders under 5 tons, add 20% extra. For orders of 5 tons or more, add 10% extra. If the area needs heavy compaction, add up to 30% extra.
So if your calculation says you need 3.4 tons, order about 4.1 tons. That small buffer saves you from a second delivery charge, which often costs more than the extra gravel itself.
If you’re short, you have two options: pay for another delivery (expensive), or leave part of the project unfinished (frustrating). In my experience, the extra material almost always gets used somewhere, a thin spot, a side path, or a small garden area you hadn’t planned yet.
Also, keep this in mind: gravel can compact by 20 to 30% after installation, especially under vehicle weight. So always factor that in before placing your order.
Gravel is one of the more affordable construction materials, but prices vary by region, stone type, and order size. The good news is that most suppliers are pretty transparent about pricing.
According to the U.S. Geological Survey (USGS), crushed stone and construction aggregate prices in the U.S. generally range from $10 to $50 per ton, depending on material type and location.
Most large suppliers sell gravel by the ton. Smaller local suppliers might sell by the cubic yard, especially for smaller orders. One cubic yard of most gravel types equals about 1.4 tons.
One ton of gravel at 2 inches deep covers roughly 100 square feet. At 4 inches deep, that same ton covers about 50 square feet. Keep that in mind when comparing quotes from different suppliers.
Order in bulk when possible; most suppliers drop the price per ton on larger orders. Also, pick up locally if you have a truck. Delivery fees for gravel can add $50 to $150, depending on distance.
If you need multiple material types, gravel, sand, and topsoil together, see if one supplier can deliver everything at once. It saves on trip fees and is easier to manage.
A gravel calculator takes a confusing job and makes it simple. You measure your area, pick a depth, choose your gravel type, and you have your number in seconds. Add your overage buffer, place your order, and you’re ready to go.
Whether you’re laying a driveway, a garden path, or fixing a drainage problem, the right amount of gravel makes all the difference. Don’t guess, measure once, calculate once, and order with confidence.

How many cubic yards are in a ton of gravel?
One ton of standard gravel equals about 0.71 cubic yards. Or flip it, one cubic yard of gravel weighs about 1.4 tons. This can vary slightly by stone type, so check with your supplier for the exact density of what you’re buying.
3/4 inch crushed stone is the top choice for driveways. Its angular edges interlock when compacted, creating a firm, stable surface that handles vehicle weight and drains rainwater well. Avoid rounded stones like pea gravel for driveways; they shift and don’t stay in place.
For most home driveways, 4 inches of gravel is the minimum. For heavy vehicles or trucks, go with 6 inches. It’s best to lay it in two layers, a 2-inch compacted base layer first, then 2 to 4 inches of surface gravel on top.
Yes. Most aggregate calculators let you switch the material type to sand, topsoil, or other fill materials. Each has a different density, so the calculator adjusts the weight estimate accordingly. The volume formula stays exactly the same, only the weight per cubic yard changes.
It depends on the depth. At 2 inches deep: 10 × 10 × 0.167 ft ÷ 27 = about 0.62 cubic yards, which is roughly 0.87 tons. At 4 inches deep, double that, about 1.23 cubic yards or 1.73 tons. Always add 10 to 20% extra for overage.
