Calculate How Much Driveway Gravel You Need

The amount of driveway gravel you will need for your home driveway is a matter of volume. Gravel is typically sold by the cubic yard—a measure of volume. Thus, you have to know the dimensions of the area in which the gravel will be poured.

Calculate How Much Driveway Gravel You Need

First, measure the distance of the driveway from front to back in feet. Next, measure the width of the driveway in feet. Finllay, determine the depth of the driveway that will be filled with gravel. This will most likely be in inches. If it is 3 inches, use a fraction of .25 (¼ of 1 foot) for the final calculation.

To calculate volume, multiply length by width by depth. Thus, if the gravel driveway is 36 feet long by 9 feet wide by 3 inches deep, multiply:

36 x 9 x .25 = 81 cubic feet of gravel

To convert this to yards, divide by 27—the number of cubic feet in a cubic yard.

81 / 27 = 3

Thus, you will 3 cubic yards of gravel for the project.
