Introduction
If you’re buying soil for a garden, filling raised beds, leveling a yard, or planning a landscaping project, you’ve probably wondered: 1 yard of dirt equals how many cubic feet? Understanding this simple conversion helps you estimate how much material you need, avoid overspending, and reduce waste.
The answer is straightforward:
1 cubic yard of dirt = 27 cubic feet of dirt.
This conversion applies to all loose materials measured by volume, including topsoil, compost, mulch, gravel, sand, and crushed stone.
In this guide, you’ll learn how the conversion works, how to calculate dirt for landscaping projects, practical examples, conversion charts, and common mistakes to avoid.
What Is a Cubic Yard?
A cubic yard is a unit of volume commonly used in landscaping, construction, and gardening.
It measures a space that is:
- 3 feet long
- 3 feet wide
- 3 feet high
To calculate its volume:
3 × 3 × 3 = 27 cubic feet
Therefore,
1 cubic yard = 27 cubic feet
This measurement is standard throughout the United States for ordering soil and other bulk landscaping materials.
What Is a Cubic Foot?
A cubic foot is another unit of volume.
It represents a cube measuring:
- 1 foot long
- 1 foot wide
- 1 foot high
Its volume is:
1 × 1 × 1 = 1 cubic foot
Because a cubic yard contains three feet on every side, it contains:
27 cubic feet
1 Yard of Dirt Equals How Many Cubic Feet?
The exact conversion is:
| Cubic Yards | Cubic Feet |
|---|---|
| 1 | 27 |
| 2 | 54 |
| 3 | 81 |
| 4 | 108 |
| 5 | 135 |
| 10 | 270 |
Formula:
Cubic Feet = Cubic Yards × 27
Example:
1 × 27 = 27 cubic feet
Why This Conversion Matters
Knowing that 1 yard of dirt equals 27 cubic feet helps with:
- Buying the correct amount of soil
- Estimating landscaping costs
- Filling raised garden beds
- Installing lawns
- Leveling uneven ground
- Planning construction projects
Ordering too much dirt increases costs, while ordering too little delays projects.
How to Convert Cubic Yards to Cubic Feet
The conversion is very simple.
Formula
Cubic Feet = Cubic Yards × 27
Example 1
2 cubic yards
2 × 27 = 54 cubic feet
Example 2
6 cubic yards
6 × 27 = 162 cubic feet
Example 3
12 cubic yards
12 × 27 = 324 cubic feet
How to Convert Cubic Feet to Cubic Yards
Sometimes measurements are given in cubic feet instead.
Use this formula:
Cubic Yards = Cubic Feet ÷ 27
Example:
54 cubic feet ÷ 27 = 2 cubic yards

Common Dirt Measurements
Many suppliers sell dirt by the cubic yard.
Here’s what common quantities equal:
| Dirt Ordered | Cubic Feet |
|---|---|
| Half yard | 13.5 |
| One yard | 27 |
| Two yards | 54 |
| Three yards | 81 |
| Four yards | 108 |
| Five yards | 135 |
How to Calculate Dirt Needed for a Project
Use these three steps.
Step 1: Measure Length
Measure the area in feet.
Example:
20 feet
Step 2: Measure Width
Example:
10 feet
Step 3: Measure Depth
Convert inches into feet.
Example:
6 inches = 0.5 feet
Now calculate:
20 × 10 × 0.5
= 100 cubic feet
Convert to cubic yards:
100 ÷ 27
≈ 3.7 cubic yards
Most suppliers recommend ordering 4 cubic yards.
Practical Example: Filling a Raised Garden Bed
Suppose your raised bed measures:
- 8 feet long
- 4 feet wide
- 1 foot deep
Volume:
8 × 4 × 1
= 32 cubic feet
Convert:
32 ÷ 27
≈ 1.19 cubic yards
You’ll need about 1¼ cubic yards of dirt.
Practical Example: Lawn Repair
Area:
30 feet × 20 feet
Depth:
3 inches
Convert depth:
3 inches = 0.25 feet
Volume:
30 × 20 × 0.25
= 150 cubic feet
Convert:
150 ÷ 27
≈ 5.56 cubic yards
Ordering 6 cubic yards provides a little extra for settling.
Practical Example: Flower Bed
Dimensions:
12 feet
6 feet
8 inches deep
Convert depth:
8 inches ÷ 12
= 0.67 feet
Volume:
12 × 6 × 0.67
≈ 48 cubic feet
Convert:
48 ÷ 27
≈ 1.78 cubic yards
Ordering 2 cubic yards is appropriate.
How Much Does One Cubic Yard of Dirt Cover?
Coverage depends on depth.
| Depth | Coverage |
|---|---|
| 1 inch | 324 sq ft |
| 2 inches | 162 sq ft |
| 3 inches | 108 sq ft |
| 4 inches | 81 sq ft |
| 6 inches | 54 sq ft |
| 12 inches | 27 sq ft |
The deeper you spread the dirt, the smaller the area it covers.
Types of Dirt Sold by the Cubic Yard
Most landscaping suppliers sell:
- Topsoil
- Fill dirt
- Garden soil
- Screened soil
- Compost blends
- Clay
- Sandy soil
- Black dirt
Regardless of the material, one cubic yard always equals 27 cubic feet.
Cubic Yard vs Cubic Foot
| Feature | Cubic Yard | Cubic Foot |
|---|---|---|
| Unit size | Larger | Smaller |
| Equals | 27 cubic feet | 1 cubic foot |
| Used for | Bulk orders | Small projects |
| Common buyers | Landscapers | Homeowners |
Weight vs Volume
People often confuse cubic yards with weight.
A cubic yard measures volume, not weight.
The weight depends on moisture and material.
Approximate weights:
| Material | Weight Per Cubic Yard |
|---|---|
| Dry topsoil | 1,800–2,000 lbs |
| Wet topsoil | 2,500–3,000 lbs |
| Compost | 1,000–1,600 lbs |
| Fill dirt | 2,000–2,700 lbs |
Even though the weight changes, every cubic yard still equals 27 cubic feet.
Benefits of Knowing This Conversion
Understanding the conversion helps you:
- Save money
- Avoid ordering too much material
- Estimate transportation needs
- Calculate landscaping costs accurately
- Plan projects confidently
- Communicate clearly with suppliers
Common Mistakes to Avoid
Mixing Square Feet and Cubic Feet
Square feet measure area.
Cubic feet measure volume.
Always include depth when calculating dirt.
Forgetting to Convert Inches
Convert inches into feet before calculating.
Example:
6 inches = 0.5 feet
Ignoring Compaction
Fresh soil settles over time.
Ordering about 5–10% extra is often a good idea.
Ordering Exact Quantities
Small shortages can delay projects.
Round up when ordering bulk materials.
Expert Tips
- Measure your project twice before ordering.
- Round up instead of down.
- Consider soil settling.
- Ask suppliers whether measurements refer to loose or compacted soil.
- Keep a conversion chart handy for future landscaping projects.
