To figure the amount of pea gravel needed for any project, measure the length, width, and desired depth in feet. Use the formula to calculate volume of pea gravel required: volume = length × width × depth. Convert the volume in cubic feet to cubic yards or bags, or tons if required.

**To determine how much gravel you’d need for any projects, here’s calculation steps:-**

- Calculate the area of the patio: Area = Length x Width in square feet
- Determine the desired depth (depth range from 2 to 6 inches) and convert in feet by dividing it by 12, such as 3′ = 3/12′ = 0.25 feet
- Calculate the volume needed: volume = Area x Depth in cubic feet
- Convert cubic feet to cubic Yards: Multiply your measurement in cubic feet by 0.037 to estimate the volume of pea gravel in cubic yards.
- Convert cubic feet to bags of 50 lb pea gravel: Multiply your measurement in cubic feet by 2 to estimate the volume of pea gravel in 50 lb bags. Typically 2 bags of 50 lb gravel is equivalent to 1 cubic foot, or 54 bags equal 1 cubic yard.
- Convert cubic feet to tons of pea gravel, use formula: Cubic yards × 1.4 = Tons of pea gravel.

Pea gravel is a decorative and useful landscaping material for making patio, mulching and making walkways, driveways, flower bed, rock garden, Xeriscaping and etc. It’s one of many types of gravel and is not to be confused with the angled gravel commonly used for drainage and underground structural construction.

Pea gravel behaves very differently, owing to its smooth round or oval-shaped stones. Unlike drainage gravel and crushed stone, pea gravel won’t lock together to form a stable base, and when you use it as a mulch or hardscape material for patio, you always have to confine it with some type of edging material, or you’ll end up losing most of it.

Since pea gravel has a smooth finish, pea gravel is also regularly used for walkways, dog runs, playgrounds, patios, and a variety of other high-traffic areas. Like crushed stone, pea gravel can also be used for underground projects, such as drainage and pipe bedding.

You are looking to buying pea gravel for your landscaping material, you need to know how much gravel you should purchase and you can load in your vehicle.

Most of pea gravel supplier which are available nearly to you, will give you option to deliver gravel at your homes, for this they should cost some money for transportation. If you have a truck or vehicle that you can use to bring gravel to your destination or construction site, then it is cheaper and faster option for you.

Pea gravel comes in bag or bulk. The common bag size of pea gravel is typically 50 lb which covers 0.5 cubic feet. The bulk quantity of pea gravel measures in cubic feet, or by cubic yards, tons, or by truckload. One full truckload typically carries approximately 25 tons of pea gravel.

**How Much pea Gravel Do You Need? Gravel calculation**

To calculate how much gravel you’ll need for a any projects like patio, walkway, driveway, flower bed, rock garden & etc, multiply the desired depth of gravel by the length and width of the project layout in same unit of measurement.

**Here’s is the pea gravel calculation steps to find out how much pea gravel do i need for a 12×12 patio?**

- Estimate Cubic inches of pea Gravel:

For Example: To determine how much gravel you’d need for a 10 by 10-foot (100 sq ft) patio layout with 3 inches of gravel, you’d perform the following calculation: 3 inches x (10×12) inches x (10×12) inches = 43,200 cubic inches. - Estimate Cubic Feet of pea Gravel:- Multiply your measurement in cubic inches by 0.000579 to estimate the volume of pea gravel in cubic feet. So, 43,200 x 0.000579 = 25 cubic feet of gravel
- Estimate Cubic Yards of pea Gravel:- Multiply your measurement in cubic feet by 0.037 to estimate the volume of pea gravel in cubic yards. So, 25×0.037 = 0.925 cubic yards of pea gravel.
- Estimate tons of pea Gravel:- Multiply your measurement in cubic yards by 1.4 to estimate the amount of pea gravel in tons. So, = 0.925 ×1.4 = 1.3 tons of pea gravel.

You’ll need approximately 0.925 cubic yards (or 25 cubic feet, 50 50 lb bag, or 1.3 tons) of pea gravel to cover a 10×10 patio with a 3-inch depth. It’s a good idea to order a bit extra to account for any irregularities in the surface or for future maintenance.

**How much does pea gravel cost**

Typically the cost of pea gravel installation depends on size of the area need to cover and types of pea gravel. The price of pea gravel is about $2.32 per square foot (or range between $0.86 to $2.32 per square foot), $4 to $7 per bag, $15 to $70 per cubic yard, $10 to $50 per US ton, $250 to $500 per truckload, or $46 is the average price per yard.

**How much pea gravel do i need for a 12×12 patio**

To determine how much gravel you’d need for a 12 by 12-foot (100 sq ft) patio layout with 6 inches of gravel, you’d perform the following calculation: 6/12 feet x 12 feet x 12 feet = 72 cubic feet. Result multiply with 0.037 to figure cubic yards, 72×0.037 = 2.66 yards, and cubic yards multiply by 1.4 to figure tons, 2.66×1.4 = 3.7 tons, and cubic feet multiply by 2 to figure bags of pea gravel, 72×2 = 144 50lb bags.

You’ll need approximately 2.66 cubic yards (or 72 cubic feet, 144 50 lb bag, or 3.7 tons) of pea gravel to cover a 12×12 patio with a 6-inch depth. It’s a good idea to order a bit extra to account. Typically for installation of a 12×12 patio with pea gravel you would cost approximately $122 (since, $46 × 2.66 = $122).

**How much pea gravel do i need for a walkway**

If your walkway is 4×35 square feet with recommended 2 inches of depth, you’ll need approximately 1 cubic yard of pea gravel and costs approximately $46 (since 1× $46 = $46) for installation. Maths calculation: volume in cubic feet = 2/12′ × 4′ × 35′ = approx 24 cubic feet, or which is nearly equal to one cubic yard.

**How much pea gravel do i need for a driveway**

If your driveway is 24×20 square feet with recommended 6 inches of depth, you’ll need approximately 9 cubic yards of pea gravel and costs approximately $414 (since 9× $46 = $414) for installation. Maths calculation: volume in cubic feet = 6/12′ × 24′ × 20′ = approx 240 cubic feet, or which is nearly equal to 9 cubic yards (since, 240 × 0.037 = approx 9 yards).

**How much pea gravel do i need for a playground**

If your playground is 25×25 square feet with recommended 4 inches of depth, you’ll need approximately 5 cubic yards of pea gravel and costs approximately $230 (since 5× $46 = $230) for installation. Maths calculation: volume in cubic feet = 4/12′ × 25′ × 25′ = approx 208 cubic feet, or which is nearly equal to 5 cubic yards (since, 208 × 0.037 = approx 5 yards).

**How much pea gravel do i need for a landscape bed**

If your landscape bed is 4×8 square feet with recommended 3 inches of depth, you’ll need approximately 0.5 cubic yards of pea gravel and costs approximately $23 (since 0.5× $46 = $23) for installation. Maths calculation: volume in cubic feet = 3/12′ × 4′ × 8′ = approx 8 cubic feet, or which is nearly equal to 0.5 cubic yards (since, 8 × 0.037 = approx 0.5 yards).

**How much does pea gravel cover**

Typically one 50 lb bag of pea gravel covers 0.5 cubic feet (or a 3 square foot at 2 inches deep), while a ton of pea gravel covers an area of 100 square feet at 2 inches deep. Likewise, a yard of pea gravel covers an area of 162 square feet at 2 inches deep, while a cubic foot of pea gravel covers an area of 6 square feet at 2 inches deep, In addition, one truckload typically carries 25 tons of pea gravel that would cover 18 cubic yards.

**How much pea gravel for 100 sq ft**

Generally for 100 square feet project area with 2-inches depth of pea gravel, you’ll need approximately 1 ton of pea gravel that would be roughly cost $232, while for 200 sq ft area, you’d need about 2 tons of pea gravel that would be cost about $464. Likewise, for 400 sq ft area, you’d need about 4 tons of pea gravel that would be cost about $928, while for 150 sq ft area, you’d need about 1.5 tons of pea gravel and costs about $348.

**Conclusions:-**

To calculate the amount of pea gravel needed for any project, measure the length, width, and desired depth in feet. Use the formula to calculate volume of pea gravel required: volume = length × width × depth.
