# Gravel Driveway Calculator – Estimate Material for a Gravel Driveway

Find the amount of gravel needed for a driveway by entering the dimensions of the driveway below. Add the price per cubic yard to estimate the cost of the stone.

## How to Estimate a Gravel Driveway

Crushed stone is a common material to use for a driveway because it offers a nice clean look, is resistant to weeds, is affordable, is easy to maintain, and is easy to install. Gravel is commonly sold by the cubic yard, so to find the material needed for a driveway find the volume in yards.

### How Many Cubic Yards of Gravel are Needed for a Driveway

Estimating gravel driveway materials is as simple as estimating the cubic yards of volume the driveway needs to be. Cubic yards are determined by multiplying length by width, by depth in yards.

Find the driveway’s length and width in yards by dividing the measurement in feet by 3. A 100’ measuring tape or measuring wheel may be needed to find these measurements depending on how long the driveway is. Find the driveway’s depth in yards by dividing the measurement in inches by 36. A driveway should have a depth of 6-8″ of gravel.

The formula to find volume is length × width × depth. To find the cubic yards of gravel needed, multiply the width in yards by the length in yards by the depth in yards.

### How Many Tons of Gravel are Needed for a Driveway

Gravel is sometimes sold by the ton instead of the cubic yard. If you know how many cubic yards of gravel are needed then find the number of tons needed by multiplying the cubic yards by 1.35.

For example, 50 cubic yards equals 67.5 tons.

50 × 1.35 = 67.5

Note that different materials have different weights. Crushed gravel weights about 1.35 tons per cubic yard, but other materials may vary in weight.
