How Many Cubic Feet of Dirt in a Dump Truck?

If you’re planning a landscaping, excavation, grading, or construction project, one of the first questions you’ll ask is: how many cubic feet of dirt in a dump truck?

The answer depends on the size of the truck, the type of dirt being hauled, and weight restrictions. While many people focus on truck size, understanding both volume and weight is essential when estimating dirt deliveries.

In general, a standard dump truck can hold between 270 and 540 cubic feet of dirt, while larger trucks can carry much more. Knowing these numbers helps you order the right amount of soil, avoid extra delivery charges, and keep your project on schedule.

This guide explains dump truck capacities, cubic-foot calculations, conversion charts, and practical examples to help you estimate dirt volumes accurately.

Quick Answer

Most standard dump trucks carry:

Dump Truck Size	Cubic Yards	Cubic Feet
Small Dump Truck	5–8 yd³	135–216 ft³
Standard Dump Truck	10–20 yd³	270–540 ft³
Large Dump Truck	20–25 yd³	540–675 ft³
Super Dump Truck	25–35 yd³	675–945 ft³

A common contractor dump truck typically holds 10 to 16 cubic yards, which equals approximately 270 to 432 cubic feet of dirt.

Understanding Dump Truck Capacity

Dump truck capacity is usually measured in cubic yards, not cubic feet.

However, homeowners and DIY users often estimate projects in cubic feet because landscaping measurements are frequently given in feet.

Since:

$1\ \text{cubic yard}=27\ \text{cubic feet}$1 cubic yard=27 cubic feet

Converting between the two units is simple.

For example:

• 10 cubic yards = 270 cubic feet
• 15 cubic yards = 405 cubic feet
• 20 cubic yards = 540 cubic feet

This conversion helps when ordering soil, topsoil, fill dirt, mulch, gravel, or sand.

How Many Cubic Feet of Dirt in a Dump Truck by Size

Different trucks have different capacities.

Small Dump Trucks

Small dump trucks are commonly used for residential projects.

Typical capacity:

• 5–8 cubic yards
• 135–216 cubic feet

These trucks are ideal for:

• Small landscaping jobs
• Garden projects
• Backyard leveling
• Residential deliveries

Standard Dump Trucks

These are the most common trucks used by contractors.

Typical capacity:

• 10–20 cubic yards
• 270–540 cubic feet

Applications include:

• Foundation work
• Driveway preparation
• Site grading
• Construction projects

Large Dump Trucks

Large trucks are often used for commercial projects.

Capacity:

• 20–25 cubic yards
• 540–675 cubic feet

These trucks reduce delivery trips and improve efficiency on larger jobs.

Super Dump Trucks

Super dump trucks can carry enormous volumes.

Capacity:

• 25–35 cubic yards
• 675–945 cubic feet

These vehicles are commonly seen on:

• Highway projects
• Large-scale excavation
• Industrial construction

Cubic Feet vs Cubic Yards Explained

Many people confuse cubic feet and cubic yards.

Here’s the relationship:

Unit	Equivalent
1 Cubic Yard	27 Cubic Feet
5 Cubic Yards	135 Cubic Feet
10 Cubic Yards	270 Cubic Feet
15 Cubic Yards	405 Cubic Feet
20 Cubic Yards	540 Cubic Feet

Because dump truck suppliers generally quote capacity in cubic yards, understanding this conversion prevents ordering errors.

How to Calculate Dirt Volume in a Dump Truck

You can estimate a truck’s dirt volume using basic measurements.

Volume Formula

$\text{Volume}=\text{Length}\times\text{Width}\times\text{Height}$Volume=Length×Width×Height

Example Calculation

Suppose a truck bed measures:

• Length = 14 feet
• Width = 7 feet
• Height = 3 feet

Calculation:

14 × 7 × 3 = 294 cubic feet

To convert to cubic yards:

294 ÷ 27 = 10.89 cubic yards

This truck can hold approximately 11 cubic yards of loose dirt.

Dump Truck Capacity Chart

The following chart provides common capacities.

Cubic Yards	Cubic Feet
5	135
6	162
8	216
10	270
12	324
15	405
18	486
20	540
25	675
30	810
35	945

This chart is useful when comparing truck sizes and estimating material requirements.

Weight vs Volume of Dirt

Volume is only part of the equation.

Dirt is heavy, and truck operators must follow legal weight limits.

Typical dirt weights:

Material	Weight per Cubic Yard
Dry Topsoil	2,000–2,400 lbs
Fill Dirt	2,000–2,700 lbs
Moist Soil	2,400–3,000 lbs
Wet Clay Soil	3,000+ lbs

For example:

A truck with a capacity of 20 cubic yards may not always carry 20 cubic yards if the soil is particularly wet or dense.

Weight restrictions often reduce the usable volume.

How Many Wheelbarrows Equal a Dump Truck Load?

Many homeowners prefer comparing truckloads to wheelbarrows.

A standard wheelbarrow holds roughly:

• 2 to 3 cubic feet

Let’s compare.

Dump Truck Capacity	Equivalent Wheelbarrows
135 cubic feet	45–68
270 cubic feet	90–135
405 cubic feet	135–203
540 cubic feet	180–270

Moving a dump truck’s worth of dirt by wheelbarrow can require hundreds of trips.

Real-World Examples

Backyard Leveling Project

Suppose you need to level a backyard measuring:

• 40 feet × 30 feet
• Fill depth = 6 inches (0.5 feet)

Calculation:

40 × 30 × 0.5 = 600 cubic feet

600 cubic feet ÷ 27 = 22.2 cubic yards

You would likely need:

• One large dump truck
• Or two smaller truckloads

Garden Bed Installation

Garden dimensions:

• 20 feet × 10 feet
• Depth = 1 foot

Calculation:

20 × 10 × 1 = 200 cubic feet

200 ÷ 27 = 7.4 cubic yards

A small dump truck can easily handle this amount.

Common Uses for Dump Truck Loads of Dirt

Dump trucks deliver dirt for many projects.

Landscaping

Uses include:

• Lawn grading
• Garden beds
• Tree planting
• Yard leveling

Construction

Applications include:

• Building pads
• Foundation preparation
• Site development
• Backfilling

Road Projects

Large trucks transport dirt for:

• Highway construction
• Drainage improvements
• Embankment creation

Agricultural Work

Farmers often order truckloads of soil for:

• Field improvements
• Drainage correction
• Land leveling

Factors That Affect Dirt Capacity

Several factors influence how much dirt fits into a truck.

Soil Moisture

Wet dirt weighs significantly more than dry dirt.

Soil Type

Clay is denser than sandy soil.

Truck Design

Some trucks have:

• Higher sidewalls
• Larger beds
• Enhanced load capacities

Legal Weight Limits

Road regulations restrict total vehicle weight.

Even if more volume could physically fit, operators may need to carry less material.

Common Mistakes When Ordering Dirt

Avoid these costly errors.

Ordering by Weight Instead of Volume

Many projects require volume estimates rather than tonnage.

Ignoring Compaction

Loose dirt settles over time.

You may need additional material.

Forgetting Delivery Access

Ensure trucks can safely reach your property.

Not Accounting for Waste

Extra material is often needed for grading and leveling.

Miscalculating Dimensions

Always measure length, width, and depth accurately before ordering.

Expert Tips for Estimating Dirt Needs

Professionals recommend:

• Measure twice before ordering.
• Add 5–10% extra material.
• Confirm truck capacity with suppliers.
• Ask whether pricing is by yard or ton.
• Consider soil compaction.
• Verify site accessibility.
• Compare delivery costs from multiple providers.

These steps help prevent delays and unnecessary expenses.
