Pea Gravel Calculator – Easy Calculate the Amount Needed

Welcome to the Pea Gravel Calculator! This calculator helps you estimate the amount of pea gravel needed for your landscaping projects, such as creating pathways, driveways, or garden beds. By entering the dimensions of the area in meters, you can quickly calculate the total weight of pea gravel required in kilograms.

How Does The Pea Gravel Calculator Work?

The pea gravel calculator works by estimating the amount of pea gravel needed for a specific project based on the dimensions you provide. Here’s how it works step by step:

Pea Gravel Calculator

  1. Input: You enter the length, width, and depth of the area you want to cover with pea gravel. These dimensions should be in meters.
  2. Calculation: The calculator takes the entered dimensions and performs the necessary calculations to determine the volume of the area in cubic meters. It multiplies the length, width, and depth together to find the volume.
  3. Weight Calculation: Assuming that 1 cubic meter of pea gravel weighs 1600 kilograms, the calculator then multiplies the volume (in cubic meters) by 1600 to calculate the total weight of pea gravel needed in kilograms.
  4. Output: The calculator displays the total weight of 10mm pea gravel required in kilograms. This output helps you determine the approximate amount of pea gravel you should purchase for your project.

It’s important to note that the calculations provided by the pea gravel calculator are estimations. They can serve as a starting point for determining the amount of pea gravel needed, but it’s always a good idea to consider additional factors and adjust the quantity accordingly.

What is Pea gravel Used For?

Pea gravel is a versatile landscaping material that finds various uses in both residential and commercial applications. Here are some common uses for pea gravel:


Pea gravel is often used to create attractive and functional pathways in gardens, yards, or parks. Its small, smooth, and rounded stones make it comfortable to walk on.


Pea gravel can be used as a surfacing material for driveways, especially in areas where a more natural or rustic look is desired. It provides good drainage and can help prevent erosion.

Patio Areas

Pea gravel can be used to create outdoor patio spaces, either as the primary surface material or as a base for other materials like pavers or flagstones.

Garden Borders

Pea gravel can be used as a decorative border material to define garden beds or separate different sections of the landscape.

Drainage Systems

Due to its excellent drainage properties, pea gravel is commonly used in drainage systems, such as French drains or around downspouts, to facilitate water flow and prevent water accumulation.

Decorative Landscaping

Pea gravel is often used for decorative purposes, such as adding texture and color to outdoor spaces. It can be used in flower beds, around trees or shrubs, or as a ground cover to enhance the aesthetic appeal of the landscape.

Water Features

Pea gravel is commonly used in water features like ponds, fountains, or dry creek beds, where its smooth and rounded stones create a natural and visually pleasing appearance.

Playground Surfaces

Pea gravel can be used as a soft and impact-absorbing surface material for playgrounds, providing a safer area for children to play.

Erosion Control

Due to its ability to allow water to pass through easily, pea gravel is used in erosion control applications, such as on slopes or embankments, to help stabilize the soil and prevent erosion.


How much pea gravel do I need per square meter?

The amount of pea gravel you need per square meter will depend on the desired depth. For example, if you want a depth of 2 inches (5 cm), you can convert it to meters (0.05 meters) and use that as the desired depth in the calculation described above.

What area will 1 ton of pea gravel cover?

The area that 1 ton of pea gravel will cover depends on the depth of the coverage. To estimate the coverage, you need to convert the weight of 1 ton (in kilograms) to cubic meters by dividing it by the density of the pea gravel. Assuming a density of 1600 kg/m³, you can divide 1 ton (1000 kg) by 1600 to obtain the volume in cubic meters. Then, divide the area by this volume to determine the coverage per square meter.

How much area will a bag of pea gravel cover?

The coverage of a bag of pea gravel will depend on the weight of the bag and the desired depth of coverage. Divide the weight of the bag (in kilograms) by the desired depth (in meters) to estimate the coverage per square meter. Keep in mind that bag sizes can vary, so check the weight indicated on the bag.

How thick should you lay pea gravel?

The recommended thickness to lay pea gravel is typically around 2 to 3 inches (5 to 7.5 cm). This depth allows for proper coverage and stability while still maintaining a natural appearance. However, in areas with heavy use or where greater stability is required, you may consider increasing the thickness accordingly.

Is 2 inches of pea gravel enough?

Whether 2 inches of pea gravel is enough depends on the specific application and your desired result. A depth of 2 inches can provide adequate coverage for some projects, such as pathways or decorative areas. However, for high-traffic areas or areas that need more stability, a thicker layer may be necessary.

Can I use pea gravel for a driveway?

Yes, pea gravel can be used for driveways. It provides good drainage and can create a natural or rustic look. However, it’s important to note that pea gravel may shift or scatter more easily compared to other compacted surfaces, so it may require periodic maintenance and re-leveling.

Is pea gravel safe for children and pets?

Pea gravel is generally considered safe for children and pets. Its smooth and rounded stones minimize the risk of injuries, and it allows water to drain through easily. However, it’s important to supervise young children during play and regularly inspect the area to ensure there are no small pieces or debris that could pose a choking hazard.

Remember, these calculations and recommendations are general guidelines. It’s always a good idea to consult with professionals or experts specific to your project to ensure accurate calculations and optimal results.


In conclusion, pea gravel is a versatile and popular landscaping material with a wide range of applications. Its small, smooth, and rounded stones make it aesthetically pleasing while offering functional benefits. Whether you’re creating pathways, driveways, or decorative areas, pea gravel can enhance the visual appeal of your outdoor spaces.

The excellent drainage properties of pea gravel make it particularly useful in areas where water management is important. It allows water to pass through easily, reducing the risk of pooling or erosion. This makes pea gravel a valuable choice for drainage systems, water features, and erosion control.

Additionally, pea gravel is a cost-effective option compared to other materials. It is readily available and easy to install, making it a convenient choice for various landscaping projects. Its natural appearance blends well with different styles and complements surrounding elements.

However, it’s essential to consider the specific requirements and regulations of your project before using pea gravel. Factors such as climate, intended use, and local guidelines may influence its suitability. Seeking advice from professionals or experts can ensure that you make informed decisions and achieve the desired results.

Overall, pea gravel offers both functional and aesthetic benefits, making it a popular choice for homeowners, landscapers, and designers alike. By incorporating pea gravel into your outdoor spaces, you can create beautiful, durable, and functional landscapes that enhance the overall appeal and enjoyment of your property.

By utilizing the pea gravel calculator and considering the unique requirements of your project, you can accurately estimate the amount of pea gravel needed, ensuring a successful and efficient landscaping endeavor.
