How Much Crusher Run Do I Need for a Patio?

When it comes to creating a patio, one important question that arises is: "how much crusher run do I need?" This query often troubles DIY enthusiasts and homeowners embarking on a new patio project. The answer to this question lies in a simple formula that calculates the amount of crushed stone required for the project. By multiplying the length (L) of the area in feet, by the width (W) of the space in feet, by the height (H) in feet, and then dividing the result by 27, you can determine the number of cubic yards of crushed stone needed. This calculation is crucial in ensuring that you’ve the right amount of material to complete your patio project successfully. So, let's dive into the details of how to calculate your crusher run needs accurately and efficiently.

What Is the Standard Size of Crusher Run?

What’s the standard size of crusher run? Crusher run is typically used underneath concrete slabs, patios, driveways, sidewalks, and walkways and ranges in sizes from ½” to 4″ with stone dust. The size of the crusher run will depend on how much weight the area will need to support and how much drainage is required. Typically, a 4-inch layer of crusher run will provide enough stability and drainage for most outdoor projects.

When determining how much crusher run you need for a patio, it’s important to calculate the square footage of the area you plan to cover. To do this, simply measure the length and width of the patio and multiply them together. For example, if your patio measures 10 feet by 10 feet, the total square footage would be 100 square feet.

Once you’ve the square footage, you can use a conversion factor to determine how many cubic yards of crusher run you’ll need. One cubic yard is equal to 27 cubic feet, so you’ll need to divide the total square footage by 27 to get the cubic yardage.

It’s important to note that crusher run is typically sold by weight, not volume. This means that the weight of the material will vary depending on the size of the stones and the moisture content.

Remember to contact a local supplier for accurate weight information and to ensure you’ve enough material for your project.

Creating a solid foundation is crucial for the success and longevity of any paver patio or walkway project. One essential component of this foundation is a gravel base, which not only provides stability but also aids in proper drainage. To ensure a strong and stable base, it’s recommended that the gravel be compacted to a depth of 6 inches. This article will delve deeper into the reasons behind this recommendation and offer some additional insights into creating the ideal gravel base for your paver project.

How Deep Should a Gravel Base Be for a Paver Patio?

When it comes to determining how deep the gravel base should be for a paver patio, 6 inches is the recommended depth. This ensures that the paver base will create a solid footing for the project and help the area drain properly. A compacted gravel base is essential for the longevity and stability of the patio or walkway.

It’s important to note that the depth of the gravel base may vary depending on the specific project and the type of soil in the area. If you’ve soft or unstable soil, you may need to increase the depth of the base to provide additional stability. On the other hand, if you’ve a firm or well-draining soil, you may be able to reduce the depth slightly.

To ensure that you’ve the correct amount of gravel for the base, you’ll need to calculate the volume of the area. This can be done by multiplying the length and width of the patio in feet, and then multiplying that by the desired depth in inches.

This depth allows for proper compaction, stability, and drainage. However, it’s important to consider factors such as soil type and drainage needs to determine the appropriate depth for your specific project. By taking these factors into account and calculating the volume of gravel needed, you can create a solid and long-lasting foundation for your patio.


This method ensures accuracy and eliminates the guesswork, allowing you to plan and procure the appropriate amount of materials for your patio project. So, whether you're embarking on a DIY patio installation or seeking professional assistance, understanding and applying this formula will help you achieve a successful and aesthetically pleasing outcome.
