If you’re planning a landscaping project, filling raised garden beds, or ordering topsoil, you may wonder: how many cubic feet are in a yard of soil?
The quick answer is:
1 Cubic Yard=27 Cubic Feet
So:
- One cubic yard of soil contains 27 cubic feet.
This conversion is standard across landscaping, gardening, and construction industries.
What Is a Cubic Yard of Soil?
A cubic yard is a unit of volume.
It represents a space measuring:
- 3 feet long
- 3 feet wide
- 3 feet high
Calculation:
3×3×3=27 Cubic Feet
This is why one cubic yard equals 27 cubic feet.
How Many Cubic Feet Are in a Yard of Soil?
The standard conversion is:
1 Cubic Yard=27 Cubic Feet
Therefore:
- 1 cubic yard = 27 cubic feet
- 2 cubic yards = 54 cubic feet
- 5 cubic yards = 135 cubic feet
- 10 cubic yards = 270 cubic feet
This applies to topsoil, garden soil, compost, and most bulk landscaping materials.
Cubic Yard to Cubic Feet Formula
The conversion formula is simple.
Standard Formula
Use:
Cubic Feet=Cubic Yards×27
Example Calculation
For 3 cubic yards of soil:
3×27=81 Cubic Feet
Answer:
- 3 cubic yards = 81 cubic feet
Soil Coverage Chart
The area covered by one cubic yard depends on depth.
| Soil Depth | Coverage Per Cubic Yard |
|---|---|
| 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 |
These values help estimate soil requirements for landscaping projects.
How Much Soil Does One Cubic Yard Cover?
At 1 Inch Deep
A cubic yard covers approximately:
- 324 square feet
At 3 Inches Deep
Coverage decreases to approximately:
- 108 square feet
This depth is common for topsoil applications.
At 6 Inches Deep
A cubic yard covers approximately:
- 54 square feet
This depth is often used for new garden beds.
Why Soil Volume Matters
Accurate soil calculations help you:
- Avoid ordering too much material
- Prevent costly shortages
- Estimate project budgets

Most soil suppliers sell bulk soil by the cubic yard.
Common Soil Calculation Mistakes
Avoid these common errors.
Confusing Cubic Feet and Square Feet
Square feet measure area.
Cubic feet measure volume.
They are not interchangeable.
Forgetting Soil Depth
Depth significantly affects coverage.
Always include depth when calculating soil requirements.
Ordering Too Little
Many homeowners underestimate soil volume needs.
Adding a small surplus is often recommended.
Expert Tips for Ordering Soil
Professionals recommend the following.
Measure Carefully
Record:
- Length
- Width
- Desired depth
before ordering.
Order Slightly Extra
Allow for settling and compaction.
Consider Soil Type
Topsoil, compost, and garden blends may settle differently after installation.
Use a Volume Calculator
Large landscaping projects benefit from precise calculations.
Real-World Example
Suppose you have a garden bed measuring:
- 9 feet long
- 6 feet wide
- 6 inches deep
Volume:
9×6×0.5=27 Cubic Feet
Convert to cubic yards:
27÷27=1 Cubic Yard
Result:
- You’ll need approximately 1 cubic yard of soil.
