Dumpster Size Calculator
Estimate the volume of your debris to find the perfect roll-off container size.
How to Choose the Right Dumpster Size
Choosing the correct dumpster size is critical for both project efficiency and budget management. If you rent a container that is too small, you'll face the expense of a "dry run" or a second rental. If you rent one that is too large, you are paying for unused air space.
Understanding Cubic Yards
Dumpster sizes are measured in cubic yards. One cubic yard is a cube that is 3 feet long, 3 feet wide, and 3 feet high. To calculate your needs, you multiply the length, width, and height of your pile of debris in feet, then divide that total by 27.
The "Air Space" Rule
Items rarely stack perfectly. When debris is tossed into a bin, it creates "void space" or air pockets. This calculator automatically applies a 15-30% buffer to account for this reality. We recommend always rounding up to the next available dumpster size to ensure you don't exceed the fill line.
Weight Limitations
While volume is important, weight is equally crucial. Heavy materials like concrete, brick, dirt, or asphalt usually require specific "heavy debris" bins. Standard roll-off containers have weight limits (often 2 to 6 tons); exceeding these limits can result in significant overweight fees.
