Whether you are a construction company working on a big project in Toronto or a homeowner cleaning up your backyard, you will no doubt need a dumpster bin rental service. But before you ask, “What size should I go with?”, you need to answer an even more important question: How much waste do I actually have?
Most rental companies offer bins measured in cubic yards (e.g., 10-yard, 14-yard, 20-yard). If you don’t know how to estimate your debris volume, choosing a bin is just a guessing game. Here is a practical guide on how to measure and visualize your waste so you never pay for empty space or a second delivery.
What Exactly is a Cubic Yard?
Dumpsters are measured by volume, specifically in “cubic yards.” A single cubic yard is a block of space that measures 3 feet long by 3 feet wide by 3 feet high.
If you are having trouble visualizing that, think of standard household appliances. One cubic yard is roughly the same size as a standard washing machine or a kitchen stove. So, a 10-yard dumpster can hold about 10 washing machines’ worth of debris.
The “Pickup Truck” Rule of Thumb
If you are staring at a pile of renovation debris in your garage, the “pickup truck method” is one of the easiest ways to estimate your volume:
- A standard full-size pickup truck bed filled level to the brim holds about 2.5 cubic yards of material.
- Therefore, a 10-yard bin is equivalent to about 4 pickup truck loads.
- A 20-yard bin is equivalent to about 8 pickup truck loads.
If you look at your pile and think, “I’d have to make 5 trips to the dump in my truck to clear this,” then you have about 12.5 cubic yards of waste. You would want to order a 14-yard bin to be safe.
How to Calculate Your Debris Volume (The Math Method)
If your waste is stacked neatly or if you are tearing down a specific structure (like an old shed or deck), you can use simple math to find your cubic yardage.
- Measure the Length, Width, and Height of your debris pile in feet.
- Multiply them together to get the total Cubic Feet. (Length × Width × Height = Cubic Feet)
- Divide that number by 27. (Since there are 27 cubic feet in one cubic yard).
Example: You have a pile of old drywall and framing that is 10 feet long, 6 feet wide, and 4 feet high.
10 x 6 x 4 = 240 cubic feet.
240 ÷ 27 = 8.8 cubic yards.
In this scenario, a 10-yard bin would be the perfect fit!
Don’t Forget the “Fluff Factor”
When calculating volume, remember that your debris won’t fit together perfectly like Tetris blocks. Items like old chairs, tree branches, or oddly shaped cabinetry will create air pockets, known as the “fluff factor.”
Always add a 20% to 30% buffer to your estimated volume to account for these air gaps. It is always cheaper to rent one slightly larger bin than to realize you are out of room and have to order a second drop-off.
