Calculate a Cubic Yard
To calculate a cubic yard, follow these important steps:
 Measure length.
 Measure width.
 Measure height.
 Multiply dimensions.
 Convert to cubic yards.
 Consider material density.
 Use online calculators.
 Consult experts if needed.
By following these steps and taking into account the material’s density, you can accurately calculate the cubic yards required for your project, ensuring you order the appropriate amount of material and avoid wastage.
Measure Length.
Measuring the length of the area or object you’re calculating the cubic yardage for is the first step in the process. Here’s how to do it accurately:
1. Choose the Right Measuring Tool:
Select a measuring tool that’s appropriate for the size of the area or object. For smaller measurements, a tape measure or ruler will suffice. For larger measurements, consider using a measuring wheel or laser distance meter.
2. Determine the Starting Point:
Identify the starting point from where you’ll begin measuring the length. This point should be a fixed reference that’s easy to identify, like a corner or edge.
3. Measure the Length:
Start measuring the length from the starting point. Hold the measuring tool straight and parallel to the ground or surface you’re measuring. Make sure the tool is taut and not sagging.
4. Read and Record the Measurement:
Once you reach the end of the area or object, read the measurement on the measuring tool. Record the measurement in an appropriate unit, such as feet, inches, or meters.
5. Consider Obstacles and Irregular Shapes:
If there are obstacles or irregular shapes in the area you’re measuring, you may need to break the measurement into smaller segments. Measure each segment separately and then add the measurements together to get the total length.
By accurately measuring the length, you’re establishing the first dimension needed to calculate the cubic yardage. In the next step, we’ll discuss how to measure the width.
Measure Width.
Once you’ve measured the length, it’s time to measure the width of the area or object you’re calculating the cubic yardage for:
1. Determine the Width Direction:
Identify the direction perpendicular to the length that you measured in the previous step. This is the direction in which you’ll measure the width.
2. Choose a Starting Point:
Select a starting point along the width direction. Similar to measuring the length, this point should be a fixed reference that’s easy to identify.
3. Measure the Width:
Start measuring the width from the starting point. Hold the measuring tool straight and perpendicular to the length you measured earlier. Ensure the tool is taut and not sagging.
4. Read and Record the Measurement:
Once you reach the end of the area or object, read the measurement on the measuring tool. Record the measurement in an appropriate unit, such as feet, inches, or meters.
5. Consider Obstacles and Irregular Shapes:
If there are obstacles or irregular shapes in the area you’re measuring, you may need to break the measurement into smaller segments. Measure each segment separately and then add the measurements together to get the total width.
By accurately measuring the width, you’re establishing the second dimension needed to calculate the cubic yardage. In the next step, we’ll discuss how to measure the height.
Measure Height.
The final dimension required to calculate cubic yardage is the height:
1. Determine the Height Direction:
Identify the direction perpendicular to both the length and width that you measured in the previous steps. This is the direction in which you’ll measure the height.
2. Choose a Starting Point:
Select a starting point along the height direction. Similar to measuring the length and width, this point should be a fixed reference that’s easy to identify.
3. Measure the Height:
Start measuring the height from the starting point. Hold the measuring tool straight and perpendicular to both the length and width you measured earlier. Ensure the tool is taut and not sagging.
4. Read and Record the Measurement:
Once you reach the end of the area or object, read the measurement on the measuring tool. Record the measurement in an appropriate unit, such as feet, inches, or meters.
5. Consider Obstacles and Irregularities:
If there are obstacles or irregular shapes in the area you’re measuring, you may need to break the measurement into smaller segments. Measure each segment separately and then add the measurements together to get the total height.
By accurately measuring the height, you’ve now established all three dimensions necessary to calculate the cubic yardage. In the next step, we’ll discuss how to multiply these dimensions to determine the cubic yardage.
Multiply Dimensions.
Now that you have the length, width, and height measurements, it’s time to multiply them to calculate the cubic yardage:
1. Understand Cubic Yards:
A cubic yard is a unit of volume that represents the space occupied by a cube that measures one yard on each side. It’s commonly used to measure the volume of materials like soil, mulch, gravel, and concrete.
2. The Formula:
To calculate cubic yardage, use the following formula:
Cubic Yards = Length x Width x Height
Make sure all dimensions are in the same unit of measurement, such as feet or meters, before multiplying them.
3. Multiply the Dimensions:
Multiply the length, width, and height measurements together. The result is the cubic yardage of the area or object you’re measuring.
4. Example:
Let’s say you have a rectangular garden bed that measures 10 feet long, 5 feet wide, and 2 feet high. To calculate the cubic yardage, multiply these dimensions:
Cubic Yards = 10 feet x 5 feet x 2 feet = 100 cubic feet
Since there are 27 cubic feet in a cubic yard, you would divide the result by 27 to convert cubic feet to cubic yards:
100 cubic feet ÷ 27 cubic feet/cubic yard = 3.7 cubic yards
Therefore, the rectangular garden bed has a volume of 3.7 cubic yards.
Convert to Cubic Yards.
In some cases, you may have measurements in different units or need to convert the result to cubic yards:
1. Understand Unit Conversions:
Cubic yards is the most common unit for measuring large volumes of materials, but you may encounter other units like cubic feet, cubic inches, or even gallons.
2. Conversion Factors:
Here are some common conversion factors:
 1 cubic yard = 27 cubic feet
 1 cubic yard = 46,656 cubic inches
 1 cubic yard ≈ 201.97 gallons (US liquid gallons)
3. Convert the Dimensions:
If your measurements are not in cubic yards, convert them using the appropriate conversion factor.
4. Example:
Suppose you have a pile of mulch measured as 150 cubic feet. To convert this to cubic yards, divide by 27:
150 cubic feet ÷ 27 cubic feet/ yard = 5.56 cubic yards
Therefore, the pile of mulch is approximately 5.56 cubic yards.
By converting to cubic yards, you can easily compare volumes and ensure you have the correct amount of material for your project.
Consider Material Density.
While calculating cubic yardage is straightforward, it’s important to consider the material’s density, especially when dealing with loose or granular materials like soil, gravel, or mulch:

What is Material Density?
Material density is the mass of a material per unit volume. It’s typically measured in pounds per cubic yard (lbs/yd³).

Why is it Important?
The density of a material affects how much space it occupies and how much it weighs. This is important because you may need to adjust your calculations or consider additional factors when ordering or transporting materials.

Loose vs. Compacted Density
Materials like soil or mulch can have different densities depending on whether they are loose or compacted. Compacted materials have a higher density and take up less space.

Estimating Material Density
If you don’t have specific density information for your material, you can use general estimates or consult with suppliers or experts in the field.
By considering material density, you can more accurately calculate the volume of material you need and avoid over or underordering, saving time and money.
