When you’re starting a new landscaping or construction project, the type and quantity of gravel you need are vital to get right. Whether you’re building a driveway, filling a drainage trench, or adding decorative stone to your garden, knowing how much gravel you need can save you time, money, and effort.
One of the most common questions people ask when dealing with gravel is, “How much does a yard of gravel weigh?” This simple question actually carries a lot of important information for anyone looking to order or transport gravel.
In this comprehensive guide, we’ll break down the details of gravel weight, helping you better understand the factors at play. From explaining what a cubic yard of gravel is to exploring its weight in pounds and kilograms, we’ll also discuss cost estimates, conversion methods, and practical applications.
By the end of this guide, you’ll have a clear understanding of gravel weight and how to calculate exactly how much you need for your projects.
What Is a Cubic Yard of Gravel?
Definition of a Cubic Yard
Before diving into the specifics of gravel weight, it’s important to understand the unit of measurement commonly used in the industry: the cubic yard. A cubic yard is a unit of volume that measures 3 feet in length, 3 feet in width, and 3 feet in height. To put it simply, a cubic yard represents the amount of space a material occupies.
For example, if you have a pile of gravel that measures 3 feet in every direction (length, width, and height), that pile is considered to be one cubic yard. To give you a visual, imagine a large box or container that fits exactly within these dimensions – that’s how much gravel you’re working with when you order a cubic yard.
Here’s a diagram to help visualize the dimensions of a cubic yard:

Weight of Gravel per Cubic Yard
General Weight Range
The weight of gravel varies significantly depending on the type and moisture content. On average, a cubic yard of gravel weighs between 2,400 to 3,400 pounds (approximately 1,090 to 1,540 kg). However, the exact weight can fluctuate based on several factors, including the type of gravel, its moisture content, and even the region it comes from.
Gravel types vary widely in their density, so it’s crucial to understand that not all gravel weighs the same. For instance, a cubic yard of fine gravel will generally weigh less than a cubic yard of coarse gravel.
Factors Influencing Weight
- Type of Gravel: The most significant factor affecting gravel weight is the type of gravel you’re using. Coarse materials like crushed granite are denser and heavier than finer gravel types like pea gravel. For example, pea gravel weighs about 2,400 pounds per cubic yard, while crushed granite can weigh upwards of 3,000 pounds per cubic yard.
- Moisture Content: Gravel’s weight also increases when it is wet. Moisture adds weight, so freshly washed or rain-soaked gravel will weigh more than dry gravel. This is an important consideration when planning transportation and storage, as wet gravel can lead to additional hauling costs.
- Size and Composition: The size and makeup of the gravel also contribute to its weight. Coarse gravel with larger particles tends to be denser and heavier, while fine gravel, with its smaller particles, tends to be lighter.
Cost of Gravel per Cubic Yard
Understanding how much a cubic yard of gravel weighs is only part of the equation. The next question people often ask is, “How much will it cost?”
The price of gravel can vary based on several factors, including the type of gravel, location, and the supplier. On average, you can expect to pay anywhere from $20 to $100 per cubic yard of gravel, with certain types being more expensive due to their availability and specific use cases.
Price Variations by Type
- Pea Gravel: Known for its smooth texture and small, rounded stones, pea gravel typically costs between $15 to $75 per cubic yard. It’s often used for landscaping and decorative purposes.
- Crushed Granite: This gravel is often used for driveways and base layers under concrete. Crushed granite generally ranges from $25 to $50 per cubic yard.
- Lava Rock: Used primarily in landscaping, lava rock is more expensive, with prices ranging from $75 to $85 per cubic yard due to its unique look and volcanic origin.
Additional Costs
In addition to the basic cost of gravel, there are several other potential expenses to consider:
- Delivery Fees: If you’re ordering a large amount of gravel, delivery costs can be significant, particularly if your location is far from the supplier. These fees depend on the distance, amount, and delivery method.
- Installation Fees: If you plan to have the gravel professionally installed, additional costs for labor will apply.
- Regional Price Differences: Gravel prices can vary depending on your location. Transportation costs for gravel from quarries to urban areas can drive prices higher, so it’s important to check local suppliers for more accurate cost estimates.
Converting Cubic Yards to Tons
Often, you’ll need to know the weight of gravel in tons rather than cubic yards. To convert cubic yards to tons, use the following formula:
1 cubic yard × weight per cubic yard ÷ 2,000 = tons
For example, let’s say you’re working with gravel that weighs 2,800 pounds per cubic yard:
2,800 lbs ÷ 2,000 = 1.4 tons
This means that a cubic yard of gravel weighing 2,800 pounds is equivalent to 1.4 tons.
Understanding this conversion is essential for accurate ordering, transportation, and budgeting for your project. It ensures that you’re getting the right amount of gravel and not overpaying for an excess you don’t need.
Gravel Weight Comparison by Type
Here’s a quick reference table for the weight of different types of gravel. Keep in mind that these are approximate values, and the actual weight can vary based on the moisture content and the region from which the gravel was sourced.
| Gravel Type | Weight per Cubic Yard (lbs) | Weight per Cubic Yard (kg) |
|---|---|---|
| Pea Gravel | 2,400–2,700 | 1,090–1,225 |
| Crushed Granite | 2,700–3,000 | 1,225–1,360 |
| Crushed Limestone | 2,500–2,800 | 1,135–1,270 |
| Lava Rock | 2,200–2,400 | 1,000–1,090 |
These weights provide a general guideline to help with calculations when purchasing gravel for different applications.
Practical Applications of Gravel
Gravel isn’t just for decorative purposes—its uses span across various industries. Here are some common applications for gravel:
Landscaping
Gravel is an essential material for landscaping projects. It’s often used for creating pathways, filling flower beds, and adding a decorative touch to gardens. Pea gravel is particularly popular for creating smooth, walkable paths, while larger crushed gravel works well for driveways.
Construction
Gravel is used as a base material for construction projects, especially in concrete mixing. It’s essential for creating a strong foundation for buildings, roads, and other structures. Crushed stone gravel is commonly used for this purpose due to its durability.
Drainage
Gravel is also vital for drainage solutions, such as French drains and erosion control systems. It allows water to flow through and away from areas, preventing flooding and water damage. Crushed stone or pea gravel is often used in these systems for its permeability and effectiveness.
Conclusion
Understanding the weight of gravel is essential when planning any project that involves this versatile material. From landscaping to construction, gravel plays a key role in a variety of applications, and knowing how much a cubic yard weighs helps ensure that you order the right amount and budget correctly.
By considering the type of gravel, its moisture content, and the associated costs, you can make informed decisions that will save time and money in the long run. So, whether you’re preparing for a driveway installation or planning a garden pathway, knowing the weight of your gravel is one step closer to achieving the perfect result for your project.
Fun Facts About Gravel
