Before you order a truckload of gravel for your driveway, patio base, or landscaping project, you need to know exactly how much you need. Order too little, and you’ll be waiting for another delivery while your project stalls. Order too much, and you’re paying for material you don’t need and trying to find a place to store it. Getting the quantity right from the start saves you time, money, and frustration.
This gravel calculator helps you determine the volume, weight, and cost of gravel for any project. Enter the length, width, and depth of the area, the calculator computes the total volume in cubic feet and cubic yards, then converts it to weight in pounds and tons. Select from common gravel types with preset densities, or enter your own custom values. Whether you’re a contractor bidding on a job, a landscaper designing a path, or a DIY homeowner planning a weekend project, this calculator delivers instant, accurate estimates. All calculations run locally in your browser, keeping your data private.
Enter the length and width of the area you need to cover, selecting from feet, inches, meters, centimeters, millimeters, or yards.
Specify the desired gravel depth, the thickness of the gravel layer you want to install.
Select the gravel type from the dropdown, the density automatically updates based on the selected type.
Adjust the density manually if your gravel type isn’t listed or if you have exact specifications.
Enter the price per cubic yard for the gravel you’re purchasing.
Set a waste factor (typically 5–15%) to account for compaction, settling, and spillage.
Add any delivery cost to get a complete project estimate.

The calculator determines the volume of gravel needed based on the area dimensions and depth. The volume is then converted to weight using the gravel density and to cost using the price per cubic yard.
Formula: Volume = Length × Width × Depth
All dimensions are converted to feet before calculation. The volume is computed in cubic feet.
Formula: Volume (cubic yards) = Volume (cubic feet) / 27
There are 27 cubic feet in one cubic yard — the standard unit for purchasing gravel.
Formula: Weight = Volume × Density
Weight is calculated in pounds using the density in pounds per cubic foot. The density varies by gravel type — crushed stone is typically about 100 lbs/ft³, while sand is about 90 lbs/ft³.
Formula: Weight (tons) = Weight (pounds) / 2000
One ton equals 2,000 pounds.
Formula: Total Cost = Volume (yd³) × (1 + Waste Factor) × Price per Cubic Yard + Delivery Cost
The waste factor accounts for compaction, settling, spillage, and other losses. A 10% waste factor is typical for most projects.
Consider a driveway measuring 20 feet long, 10 feet wide, with a desired gravel depth of 3 inches. The homeowner is using crushed stone with a density of 100 lbs/ft³, costing $45 per cubic yard, with a 10% waste factor and $50 delivery.
Step 1: Convert depth to feet
3 inches = 3/12 = 0.25 feet
Step 2: Calculate volume
Area = 20 × 10 = 200 ft²
Volume = 200 × 0.25 = 50 ft³
Volume (yd³) = 50 / 27 = 1.85 yd³
Step 3: Calculate weight
Weight = 50 × 100 = 5,000 lbs = 2.50 tons
Step 4: Apply waste factor and cost
Volume with waste = 1.85 × 1.10 = 2.04 yd³
Gravel cost = 2.04 × $45.00 = $91.80
Total cost = $91.80 + $50.00 = $141.80
Interpretation: A 20×10 foot driveway with 3 inches of gravel needs about 2.04 cubic yards of gravel, weighing 2.5 tons. The total cost, including delivery, is approximately $142. This estimate helps the homeowner plan their budget and order the right amount of material.
The amount of gravel depends on the driveway’s length, width, and desired depth. A typical driveway needs 4–6 inches of gravel for a stable base. The calculator provides a precise estimate based on your specific dimensions.
Crushed stone (also called crushed gravel) is the best option for driveways because the angular pieces lock together well, creating a stable, compacted surface. Crusher run is also a popular choice because it includes stone dust that helps with compaction.
A gravel driveway typically requires 4–6 inches of gravel for a durable, long-lasting surface. The exact depth depends on the soil conditions and the expected traffic load.
A cubic yard of gravel is the volume of a cube that measures 3 feet on each side (3 × 3 × 3 = 27 cubic feet). It’s the standard unit for purchasing gravel. One cubic yard of gravel typically weighs between 2,400 and 3,000 lbs, depending on the gravel type and density.
Gravel costs vary by type, location, and quantity. Crushed stone typically costs $30–$60 per cubic yard, while decorative gravel like pea gravel or river rock can cost $50–$100 per cubic yard. Delivery fees add to the total cost.
The density of gravel varies by type. Crushed stone is typically about 100 lbs/ft³. Pea gravel is about 95 lbs/ft³. Limestone is about 110 lbs/ft³. Sand is about 90 lbs/ft³. The calculator includes presets for common gravel types.
Adding a waste factor accounts for compaction, settling, spillage, and irregularities in the surface. Without it, you’re likely to come up short. A 10–15% waste factor is standard for most gravel projects.
For a circular area, you’d need to calculate the area separately using the formula for a circle (π × radius²). The calculator is currently designed for rectangular areas, but you can approximate a circular area by entering the dimensions of a square that closely fits the circle.
