Cubic Yard Calculator
Calculate cubic yards for concrete, gravel, sand, soil, stone, mulch and other construction materials using length, width and depth.
Project inputs
Enter your project dimensions, then press Calculate.
Result
Volume calculated from your project dimensions.
Actual material requirements may vary because of compaction, uneven surfaces and site conditions.
How this calculator works
Dimensions are converted to feet before calculating the final volume.
What Is a Cubic Yard?
A cubic yard is a unit of volume commonly used for construction and landscaping materials. One cubic yard represents the volume of a cube measuring one yard long, one yard wide and one yard high.
One cubic yard equals exactly 27 cubic feet. Concrete, gravel, sand, soil, stone and mulch are commonly measured and ordered in cubic yards.
How to Calculate Cubic Yards
To calculate cubic yards, first calculate the volume in cubic feet by multiplying length by width by depth. Then divide the cubic-foot result by 27.
Example
Suppose your project measures 10 feet long, 10 feet wide and 4 inches deep.
Four inches is approximately 0.333 feet.
33.33 ÷ 27 ≈ 1.23 yd³
The required volume is approximately 1.23 cubic yards.
How Many Cubic Feet Are in a Cubic Yard?
There are exactly 27 cubic feet in one cubic yard.
| Cubic Feet | Cubic Yards |
|---|---|
| 27 ft³ | 1 yd³ |
| 54 ft³ | 2 yd³ |
| 81 ft³ | 3 yd³ |
| 135 ft³ | 5 yd³ |
| 270 ft³ | 10 yd³ |
How to Convert Cubic Feet to Cubic Yards
Divide the number of cubic feet by 27 to convert cubic feet to cubic yards.
For example, 54 cubic feet divided by 27 equals 2 cubic yards.
Materials Commonly Measured in Cubic Yards
- Concrete
- Gravel
- Crushed stone
- Sand
- Topsoil
- Fill dirt
- Mulch
- Landscape rock
How Much Extra Material Should You Order?
Real projects may require slightly more material than the theoretical volume because of compaction, uneven excavation, spillage or site conditions.
Use the Extra material field in the calculator to add an allowance to your result.
Cubic Yard Calculator for Concrete
Concrete is commonly ordered by the cubic yard in the United States. Enter the length, width and thickness of your slab, footing or other concrete area to estimate the required volume.
