How much gravel do I need?
To calculate the amount of gravel you need, the calculator determines the area you're covering and multiplies it by the depth of gravel. Because depth is normally measured in inches while length and width are measured in feet, the calculator converts the depth to feet before calculating the volume.
The result is shown in cubic yards, which is a common unit used when ordering bulk landscaping materials.
Adding a small allowance can help account for waste, uneven areas, and settling. The appropriate amount depends on your project and site conditions.
Buying Gravel: What to Know
Gravel is commonly sold by the cubic yard or by the ton, depending on the supplier and type of gravel. Our calculator gives you the volume you need in cubic yards based on the dimensions and depth of your project.
When ordering gravel, consider adding a small amount to account for waste, uneven areas, and settling. The amount of extra material you need will depend on your project and site conditions.
For larger projects, buying in bulk is usually more practical than purchasing individual bags. For smaller projects, bagged gravel may be easier to transport and handle.
