What Is a Cubic Yard?
A cubic yard is a unit of volume equivalent to a cube with a length, width and height of 1 yard. One yard is equal to 3 feet, or 36 inches, so 1 cubic yard is equal to 27 cubic feet — 3 feet long, 3 feet wide and 3 feet high. To get an idea of how big a cubic yard is, a standard washing machine is about the size of 1 cubic yard. Dumpsters are similar in shape to long cubes, so dumpster volume is calculated in cubic yards — not to be confused with regular yards, which measure a two-dimensional area. Cubic yards measure three-dimensional volume, such as a pile of debris. Knowing how to calculate cubic yards and estimate the amount of debris you have will help you choose the right container size for your project.
How Much Is a Cubic Yard?
Wondering how to measure cubic yards? It’s surprisingly simple.
Measure the Area
First, measure the area in feet. To convert inches to feet, divide the number of inches by 12. Measure the length, width and height (or depth) of your debris. Use a tape measure for this purpose. For larger areas, a measuring wheel may be useful.
Calculate the Volume
Next, multiply the length, width and height measurements. Divide this number by 27. This will give you the volume in cubic yards. For how to calculate cubic yards using the graphic above as an example, the steps would be: You can also easily calculate cubic yardage by converting all three dimensions of your material into yards and multiplying them. For example, if you dig up a flower bed that is 9 feet long, 3 feet wide and 12 inches deep, you will have one cubic yard of dirt. This is how it breaks down: Multiplying the three dimensions — length, width and height/depth — gives you the total cubic yardage of your debris. In this example, 3 yards x 1 yard x 1/3 yard = 1 cubic yard of dirt.
How Big Is a Cubic Yard?
Once you’ve figured out how to measure cubic yards, it may still be difficult to envision how much is a cubic yard. Dumpsters with varying dimensions can hold the same amount of volume. Some may be long, some may be tall and some may be short — but they may all hold the same number of cubic yards inside. It can help to picture cubic yards as wheelbarrow loads, trash bags or pickup truck loads.
Here’s how they break down, approximately, for several of our most common dumpster sizes.
Dumpster Size | 33-Gallon Trash Bags | Wheelbarrow Loads | Pickup Truck Loads |
|---|---|---|---|
10 cubic yard dumpster | 50 to 70 | 80 to 100 | 3 |
12 cubic yard dumpster | 65 to 85 | 98 to 118 | 3.5 |
15 cubic yard dumpster | 80 to 100 | 125 to 145 | 4.5 |
20 cubic yard dumpster | 110 to 130 | 170 to 190 | 6 |
30 cubic yard dumpster | 170 to 190 | 260 to 280 | 9 |
40 cubic yard dumpster | 230 to 250 | 350 to 370 | 12 |
How Much a Cubic Yard Weighs by Debris Type
Besides volume, the weight of your debris is an important factor in choosing the right dumpster size. Each dumpster has a set weight limit, which is different from its volume capacity. Cubic yards are a measure of volume, not a measure of weight. So, depending on what you’re throwing away, two full 10 cubic yard dumpsters could have significantly different weights. Our weight calculator is helpful for determining the weight of your specific debris types. Here are the approximate weights of 1 cubic yard of common materials.
1 Cubic Yard of Material | Weight in Pounds |
|---|---|
Household debris | 150 to 300 |
Scrap wood | 300 |
Drywall | 500 |
Mulch | 600 to 1,000, depending on moisture content |
Scrap metal | 1,000 |
Soil | 2,000 |
Carpet | 2,300 to 3,200 |
Sand | 2,700 |
Gravel or Rock | 3,000 |
Concrete | 4,000 |
Asphalt | 4,000 |
