Enter the length (ft), the width (ft), and the depth (ft) into the Gravel Volume Calculator. The calculator will evaluate and display the Gravel Volume. 

Gravel Volume Formula

The following formula is used to calculate the Gravel Volume. 

GV = L * W * D
  • Where GV is the Gravel Volume (ft^3)
  • L is the length (ft) 
  • W is the width (ft) 
  • D is the depth (ft) 

How to Calculate Gravel Volume?

The following example problems outline how to calculate Gravel Volume.

Example Problem #1

  1. First, determine the length (ft).
    1. The length (ft) is given as 10.
  2. Next, determine the width (ft).
    1. The width (ft) is calculated as: 40.
  3. Next, determine the depth (ft).
    1. The depth (ft) is found to be: .25.
  4. Finally, calculate the Gravel Volume using the formula above: 

GV = L * W * D

Inserting the values from above yields: 

GV = 10 *40 * .25 = 100 (ft^3)


What types of projects is gravel volume calculation important for?

Gravel volume calculation is crucial for various projects, including landscaping, construction of driveways, pathways, drainage systems, and foundation backfilling. Accurate calculation helps in budgeting and ensuring the right amount of gravel is ordered and used.

How does the depth of gravel impact its usage in projects?

The depth of gravel affects its functionality and efficiency in projects. For instance, deeper gravel layers are better for drainage projects, while shallower layers are often sufficient for decorative purposes. The depth also influences the overall cost and volume of gravel needed.

Can the gravel volume calculator be used for different types of gravel?

Yes, the gravel volume calculator can be used for different types of gravel since the calculation is based on the dimensions of the area to be covered and the desired depth. However, the specific type of gravel might affect the weight and, subsequently, the cost, which might require additional calculations.
