Gravel Calculator: How Much Do You Need?

Whether you need pea gravel or aggregate, our calculator can help estimate the right amount of gravel for your project based on the area’s dimensions.

To calculate the required amount of gravel, measure the length, width, and depth of the area in feet. Multiply these values to determine cubic feet. Then, divide the cubic feet by 27 to find cubic yards.

Finally, to convert cubic yards to tons, multiply by 1.4.

Cubic feet = length multiplied by width multiplied by depth in feet. Cubic yards = cubic feet divided by 27. Tons = cubic yards multiplied by 1.4.

Pea Gravel Calculations for Driveway Coverage

Gravel Calculator How Much Do You Need

To cover a driveway with pea gravel, follow these steps:

1. Measure the driveway: 20 feet length, 10 feet width.

2. Determine desired thickness: 2 inches (0.167 feet).

3. Calculate cubic feet: length x width x depth = 20 ft x 10 ft x 0.167 ft = 33.4 cubic feet.

4. Convert cubic feet to cubic yards: divide by 27 (33.4 ft³ ÷ 27 = 1.237 cubic yards).

5. Find the required amount in tons: multiply by 1.4 (1.237 cubic yards x 1.4 = 1.732 tons).

6. Therefore, you’ll need approximately 1.732 tons of pea gravel for your driveway.

How Much Gravel Do I Need: Determining Depth

The amount of gravel you need depends on the area’s square footage and the desired depth.

Laying a pea gravel pathway typically requires a depth of 3-6 inches, depending on the base soil. For softer soil, a depth of 4-6 inches is recommended, while for firm and stable ground, 3-4 inches may suffice. When using pea gravel for landscaping instead of mulch, a thickness of 2-2.5 inches is ideal.

For driveways, crushed stone is usually used instead of gravel.

Gravel is a naturally occurring material that is commonly used for landscaping, while crushed stone is preferred by contractors for driveways and construction. Gravel is classified by name or size, indicated by a “#” sign followed by a number. The lower the number, the larger the gravel.

Here are some common types of gravel:

Gravel Type | Weight per Cubic Yard (Pounds) | Weight per Cubic Yard (Tons)

— | — | —

Pea Gravel | 2,800 – 3,400 lbs | 1.4 – 1.7 tons

Crushed Stone | 2,200 – 2,700 lbs | 1.1 – 1.35 tons

River Rock | 2,700 – 3,000 lbs | 1.35 – 1.5 tons

Decomposed Granite | 2,000 – 2,600 lbs | 1 – 1.3 tons

Crushed Limestone | 2,300 – 2,800 lbs | 1.15 – 1.4 tons

– Pea gravel, with its small size resembling a pea, is an inexpensive and versatile option for landscaping and construction projects.

– Crushed stone is another popular option, known for its affordability and wide range of colors and shapes.

– River rock is a heavier option, adding aesthetic appeal to landscaping projects.

– Decomposed granite is lightweight and commonly used for pathways and smaller construction projects.

– Crushed limestone offers a balance between weight and appearance, making it suitable for various applications.

River rock, also known as river stone, is a smooth and rounded stone that is found in rivers and creeks. It comes in various colors such as white, light brown, and black, and is available in different sizes, ranging from small to medium.

Lava rock, or volcanic rock, is another type of stone that is formed from cooled lava. It is commonly found in red, black, or gray colors and is often used in landscaping projects.

Bank gravel is a mixture of large rocks, small rocks, and sand that is found along the banks of rivers and creeks. It is popular for landscaping due to its excellent drainage properties.

Marble chips, as the name suggests, are made from marble and are commonly used in landscaping projects like flower beds and walkways. They are typically white in color.

FAQ (Frequently Asked Questions)

Is gravel the same as crushed stone?

Gravel and crushed stone are different. Aggregate companies produce crushed stone by mining large rocks and crushing them into smaller, angular pieces. Crush is ideal for driveways and construction products, while gravel is better for landscaping.
