How do you measure gravel driveway?

First, find the total square footage of your driveway. You can find this by multiplying the length of the driveway by the width of the driveway. When you have determined the square footage, you need to decide how thick you will apply the gravel.

At a depth of 1", 1 cubic yard of gravel will cover 320 square feet. So for example, if you would like to put down 3 inches of material over 1000 square feet, you would do the following.

1000 square ft./320 = 3.125

3.125*3" depth = 9.375 yards
