If you are buying mulch, gravel, soil, concrete, sand, compost, or other bulk materials, you may wonder how many cubic feet are in a yard. The answer depends on what type of “yard” you mean.
When measuring volume, the term usually refers to a cubic yard, not a linear yard. One cubic yard equals 27 cubic feet.
The calculation is straightforward:
1 cubic yard = 3 feet × 3 feet × 3 feet
3 × 3 × 3 = 27 cubic feet
Therefore, 1 cubic yard contains 27 cubic feet.
This measurement is especially useful for landscaping and construction projects because materials such as mulch, topsoil, gravel, sand, compost, and concrete are commonly sold by the cubic yard.

What Is a Cubic Yard?
A cubic yard is a unit of volume.
It represents a three-dimensional space measuring:
- 3 feet long
- 3 feet wide
- 3 feet high
To calculate the volume:
3 ft × 3 ft × 3 ft = 27 cubic feet
So one cubic yard is a cube that measures 3 feet on every side.
It is important not to confuse a yard with a cubic yard.
A yard is a unit of length:
1 yard = 3 feet
A cubic yard is a unit of volume:
1 cubic yard = 27 cubic feet
Why Is 1 Cubic Yard Equal to 27 Cubic Feet?
The reason is that volume requires multiplying length, width, and height.
One yard is equal to 3 feet. Therefore, a cubic yard can be represented as:
1 yard × 1 yard × 1 yard
Converting each dimension to feet:
3 feet × 3 feet × 3 feet
Then multiply:
3 × 3 × 3 = 27
Therefore:
1 cubic yard = 27 cubic feet
The number 27 comes from cubing the conversion factor of 3:
3³ = 27
How to Convert Cubic Yards to Cubic Feet
The conversion is simple.
Formula
Cubic feet = Cubic yards × 27
For example, if you have 4 cubic yards of mulch:
4 × 27 = 108 cubic feet
Therefore, 4 cubic yards equals 108 cubic feet.
More Examples
For 2 cubic yards:
2 × 27 = 54 cubic feet
For 6 cubic yards:
6 × 27 = 162 cubic feet
For 10 cubic yards:
10 × 27 = 270 cubic feet
The same formula works for any number of cubic yards.
How to Convert Cubic Feet to Cubic Yards
You can also convert in the opposite direction.
Formula
Cubic yards = Cubic feet ÷ 27
For example, suppose you have 81 cubic feet of soil.
81 ÷ 27 = 3 cubic yards
Therefore, 81 cubic feet equals 3 cubic yards.
Another example:
54 ÷ 27 = 2 cubic yards
So 54 cubic feet equals 2 cubic yards.

How to Calculate Cubic Yards From Length, Width, and Depth
If you are trying to determine how much material you need, you can calculate cubic yards from the dimensions of the area.
First, measure:
- Length in feet
- Width in feet
- Depth in feet
Then use:
Length × Width × Depth = Cubic Feet
After finding the cubic feet, divide by 27:
Cubic Feet ÷ 27 = Cubic Yards
Example
Suppose you have a garden bed that is:
- 20 feet long
- 10 feet wide
- 0.25 feet deep
First calculate the volume:
20 × 10 × 0.25 = 50 cubic feet
Then convert to cubic yards:
50 ÷ 27 = 1.85 cubic yards
You would need approximately 1.85 cubic yards of material.
When purchasing bulk material, you may choose to round up based on the supplier’s available quantities and the expected settling or compaction of the material.
How Many Cubic Feet Are in a Yard of Mulch?
A cubic yard of mulch contains exactly 27 cubic feet.
However, the important question for landscaping is often how much surface area that cubic yard will cover.
Coverage depends on the depth of the mulch.
For example, one cubic yard contains 27 cubic feet of material. If it is spread over a large area at a shallow depth, it will cover more square feet. If it is spread more deeply, it will cover fewer square feet.
The basic relationship is:
Square feet × depth in feet = cubic feet
Then:
Cubic feet ÷ 27 = cubic yards
How Many Cubic Feet Are in a Yard of Soil?
A cubic yard of soil is also 27 cubic feet.
The same conversion applies regardless of the material.
So:
- 1 cubic yard of topsoil = 27 cubic feet
- 1 cubic yard of garden soil = 27 cubic feet
- 1 cubic yard of compost = 27 cubic feet
- 1 cubic yard of sand = 27 cubic feet
- 1 cubic yard of gravel = 27 cubic feet
The volume conversion remains the same even though the weight of each material can be very different.
How Many Cubic Feet Are in a Yard of Gravel?
One cubic yard of gravel equals 27 cubic feet.
However, gravel is much heavier than many landscaping materials, so weight becomes an important consideration when transporting it.
The number of cubic feet does not change based on the material:
1 cubic yard = 27 cubic feet
What changes is the weight per cubic foot.
How Many Cubic Feet Are in a Yard of Concrete?
One cubic yard of concrete contains 27 cubic feet.
Concrete is commonly ordered in cubic yards for larger construction projects.
For example:
3 cubic yards of concrete × 27 = 81 cubic feet
Therefore, 3 cubic yards of concrete equals 81 cubic feet.
Because concrete is heavy and time-sensitive, accurate measurements are especially important when calculating how much is needed for a slab, footing, driveway, walkway, or other project.
How Many Cubic Feet Are in a Yard of Sand?
One cubic yard of sand equals 27 cubic feet.
If you need 4 cubic yards of sand:
4 × 27 = 108 cubic feet
So 4 cubic yards is equivalent to 108 cubic feet.
The weight will vary depending on the type and moisture content of the sand.
How Many Cubic Feet Are in a Yard of Compost?
One cubic yard of compost contains 27 cubic feet.
For example, if you purchase 2 cubic yards:
2 × 27 = 54 cubic feet
Therefore, you would have 54 cubic feet of compost.
Cubic Feet vs. Square Feet
It is important to understand the difference between square feet and cubic feet.
Square Feet
Square feet measure area.
For example:
10 feet × 20 feet = 200 square feet
This describes a two-dimensional surface.
Cubic Feet
Cubic feet measure volume.
For example:
10 feet × 20 feet × 1 foot = 200 cubic feet
This adds depth to the measurement.
When buying mulch, soil, gravel, sand, or concrete, you generally need a volume measurement such as cubic feet or cubic yards.
Cubic Yard vs. Yard: What’s the Difference?
The terms are sometimes used interchangeably in casual conversation, but they describe different measurements.
A yard measures length:
1 yard = 3 feet
A cubic yard measures volume:
1 cubic yard = 27 cubic feet
For example, saying “one yard of fabric” generally refers to a length measurement, while “one cubic yard of mulch” refers to volume.
This distinction is important when calculating material quantities.
How Many Bags Equal One Cubic Yard?
The answer depends on the size of the bags.
For example, if each bag contains 2 cubic feet:
27 ÷ 2 = 13.5 bags
So you would need approximately 14 two-cubic-foot bags to equal one cubic yard.
If each bag contains 1 cubic foot:
27 ÷ 1 = 27 bags
Therefore, you would need 27 one-cubic-foot bags.
If each bag contains 1.5 cubic feet:
27 ÷ 1.5 = 18 bags
So approximately 18 bags equal one cubic yard.
How Many 2-Cubic-Foot Bags Are in a Cubic Yard?
One cubic yard equals 27 cubic feet.
If each bag contains 2 cubic feet:
27 ÷ 2 = 13.5
Therefore, 13.5 two-cubic-foot bags equal one cubic yard.
Since bags are normally sold as whole units, you would need 14 bags to have at least one cubic yard of material.
How Many 3-Cubic-Foot Bags Are in a Cubic Yard?
If each bag contains 3 cubic feet:
27 ÷ 3 = 9
Therefore:
9 three-cubic-foot bags = 1 cubic yard
This is an exact conversion.
How Many 1-Cubic-Foot Bags Are in a Cubic Yard?
Since one cubic yard contains 27 cubic feet:
27 ÷ 1 = 27
Therefore, 27 one-cubic-foot bags equal one cubic yard.
