Gravel Calculator
Estimate the gravel area, volume, weight, cubic yards, bags and optional material cost from your project dimensions, depth and density.
Calculate Gravel Needed
Choose total area, rectangle or circle, enter the gravel depth and density, and optionally add price and bag-size information.
How to Use the Gravel Calculator
- Choose Use total area, Rectangle, or Circle.
- Enter the project area or the required dimensions.
- Enter the desired gravel depth and choose the correct unit.
- Select the standard gravel density or enter a custom supplier density.
- Optionally enter a material price and bag size.
- Click Calculate Gravel to see area, volume, weight, bags and cost.
Results are estimates for material planning. Actual bulk density can vary with gravel type, moisture, grading and compaction. Delivery, labor and other project costs are not included.
Frequently Asked Questions (FAQs)
It estimates the project area, gravel volume, weight, cubic yards, bag quantity and optional material cost from your entered measurements, depth and gravel density.
First determine the area, then multiply the area by the desired gravel depth to obtain volume. Density is then used to estimate the material weight.
Many surface-cover projects use roughly 2 to 4 inches as a starting planning range, but the required depth depends on the application, base conditions and local construction requirements.
Density determines how much mass is contained in a given volume. Different gravel materials and conditions can have different bulk densities, so supplier data can provide a more accurate estimate.
Yes. Enter an optional price and price unit for a material-cost estimate. Enter the volume of one bag and its unit to estimate the number of bags required.
No. The optional cost calculation uses only the price you enter. Delivery, labor, taxes and other project expenses are not included.
