How Many Cubic Yards Fit in a Dump Truck?
If you’re ordering gravel, soil, mulch, sand, or other bulk materials, one of the most important questions to ask is how many cubic yards fit in a dump truck? Understanding dump truck capacity helps you estimate delivery costs, determine the number of truckloads required, and avoid ordering too much or too little material.
Many people assume all dump trucks carry the same amount of material, but that’s not the case. Dump truck capacity varies depending on the truck size, the type of material being hauled, and legal weight restrictions. A truck may have enough space to hold a certain volume, but the weight of the material can limit how much it can legally transport.
Whether you’re planning a landscaping project, driveway installation, excavation job, or construction project, knowing the average dump truck capacity can help you make better decisions before placing an order.
What Is a Cubic Yard?
A cubic yard is a unit of volume commonly used for landscaping and construction materials.
One cubic yard equals:
| Unit | Equivalent |
| Cubic Feet | 27 |
| Cubic Inches | 46,656 |
| Cubic Meters | 0.7646 |
Bulk materials such as gravel, topsoil, mulch, sand, and crushed stone are usually sold by the cubic yard.
When suppliers discuss dump truck capacity, they are generally referring to the number of cubic yards a truck can transport in a single load.
Average Dump Truck Capacity
Most standard dump trucks carry between 10 and 14 cubic yards of material.
However, capacity varies based on truck type.
| Dump Truck Type | Typical Capacity |
| Small Dump Truck | 5–8 Cubic Yards |
| Standard Dump Truck | 10–14 Cubic Yards |
| Large Dump Truck | 16–20 Cubic Yards |
| Super Dump Truck | 20–25 Cubic Yards |
For residential projects, suppliers commonly use standard dump trucks capable of carrying around 10 to 14 cubic yards.
Why Capacity Varies by Material
Volume is only part of the equation. Weight is often the limiting factor.
A dump truck may physically hold 14 cubic yards of material, but if the material is extremely heavy, the truck may reach its weight limit before it reaches its volume limit.
This is why gravel, sand, and crushed stone often require smaller loads than lighter materials such as mulch.
How Many Cubic Yards of Gravel Fit in a Dump Truck?
Gravel is one of the heaviest landscaping materials.
On average:
- Gravel weighs around 2,700 to 3,000 pounds per cubic yard.
- Most standard dump trucks carry between 10 and 14 cubic yards of gravel.
A full truckload often contains approximately:
12 cubic yards of gravel
This amount may vary depending on local transportation regulations and truck specifications.
How Many Cubic Yards of Soil Fit in a Dump Truck?
Topsoil is generally lighter than gravel but heavier than mulch.
Average weight:
- 2,000–2,400 pounds per cubic yard
Most dump trucks can haul:
10–15 cubic yards of topsoil
Moisture content can significantly affect soil weight.
Wet soil can weigh much more than dry soil.
How Many Cubic Yards of Mulch Fit in a Dump Truck?
Mulch is relatively lightweight.
Average weight:
- 400–800 pounds per cubic yard
Because mulch is light, trucks are often limited by volume rather than weight.
Many dump trucks can transport:
15–20 cubic yards of mulch
in a single load.
Dump Truck Capacity Chart by Material
| Material | Average Cubic Yards Per Truck |
| Gravel | 10–14 |
| Crushed Stone | 10–14 |
| Sand | 10–12 |
| Topsoil | 10–15 |
| Fill Dirt | 10–15 |
| Mulch | 15–20 |
| Compost | 12–18 |
These figures represent general estimates and may vary between suppliers.
How Many Truckloads Do You Need?
To estimate the number of truckloads required, divide the total cubic yards needed by the truck’s capacity.
Example
Project Requirement:
36 Cubic Yards of Gravel
Truck Capacity:
12 Cubic Yards
Calculation:
36 ÷ 12 = 3
Result:
3 truckloads required
Common Residential Projects
Gravel Driveway
A typical two-car gravel driveway may require:
- 5–10 cubic yards for resurfacing
- 10–20 cubic yards for new construction
In many cases, one truckload is sufficient.
Raised Garden Beds
Most raised garden bed projects require:
- 1–5 cubic yards of soil
This quantity usually represents only a fraction of a truckload.
Large Landscaping Projects
Major landscaping projects often require:
- 10–30 cubic yards of mulch
- 10–25 cubic yards of soil
- 15–40 cubic yards of gravel
Multiple truckloads may be needed depending on the material.
Factors That Affect Dump Truck Capacity
Several factors influence how much material a truck can transport.
The most important factor is material weight. Heavier materials reduce the total volume that can be legally hauled.
Moisture content can also increase weight significantly. Wet soil, wet sand, and saturated gravel can weigh considerably more than dry material.
Truck size and local road regulations also affect hauling capacity. Some regions enforce stricter weight limits than others.
Should You Order a Full Truckload?
Ordering a full truckload is often the most cost-effective option for large projects.
Many suppliers charge a delivery fee regardless of whether the truck is half full or completely full. If your project requires a substantial amount of material, ordering enough to maximize each delivery can reduce transportation costs.
However, always ensure you have adequate space on-site for unloading and storing the material.
Frequently Asked Questions
How many cubic yards fit in a standard dump truck?
Most standard dump trucks carry between 10 and 14 cubic yards of material.
How many cubic yards of gravel are in a dump truck?
A typical dump truck usually carries about 12 cubic yards of gravel, depending on weight restrictions.
How many cubic yards of soil fit in a dump truck?
Most dump trucks can transport between 10 and 15 cubic yards of topsoil.

How do I calculate truckloads needed?
Divide the total cubic yards required by the dump truck’s carrying capacity.
Final Thoughts
Understanding how many cubic yards fit in a dump truck can help you estimate project costs, schedule deliveries, and order materials more efficiently. While most standard dump trucks carry between 10 and 14 cubic yards, actual capacity depends on the material being transported and local weight regulations.
Before ordering gravel, soil, mulch, sand, or other bulk materials, calculate your required volume carefully and confirm truck capacities with your supplier. A little planning can help prevent delays and ensure your project stays on budget.
