Here's the distinction that matters for Yard Waste Dumpster Rental: it is green material that many facilities compost separately from landfill waste. The question that decides the quote is whether the hauler already knows that the composting rate survives only while the container holds nothing but green material.
Picture the container two ways: full to the rim, or full to the ton limit. Dense debris hits the second ceiling long before it reaches the first. The booking pattern here skews toward homeowners and landscapers, since the job produces a fairly predictable volume of debris, which is why 10 or 15 or 20 yard containers cover most of what actually gets ordered. Know your timeline and know your restrictions. Those two facts get you a straight answer instead of a guess.
Furniture, boxes and old fixtures take up room without weighing much, so volume decides the size here, not a hauler's weight chart. Ask whether the size recommendation accounts for the material's density, not just its volume -- a driveway full of dirt needs a smaller box than the same space full of moving boxes. The dumpster you actually need is the one sized to the heaviest material in the load, not the one that looks roomy enough for everything else.
