What Size Dumpster Do I Need? A No-Guesswork Guide
10, 15, 20, 30, or 40 yards? Match your project to the right dumpster size with real capacity comparisons, weight-limit warnings, and the one rule that saves money.
Start with the project, not the dumpster
The fastest way to pick wrong is to start from prices. Start from your debris: a kitchen remodel produces cabinets, counters, drywall, and flooring — call it 12–15 cubic yards loose. A single-layer roof tear-off on a 2,000 sq ft home produces about 20–25 squares of shingles, which is a weight problem more than a volume problem. A garage cleanout is usually 8–10 loose yards of accumulated everything.
The quick matcher
10-yard: garage/basement cleanouts, small bathroom remodels, concrete and dirt (heavy debris must go in small boxes). 15-yard: kitchen or bath remodels, flooring tear-outs, medium cleanouts. 20-yard: the most-rented size — roof tear-offs, whole-room renovations, large cleanouts. 30-yard: major renovations, new construction, whole-home cleanouts. 40-yard: commercial construction and demolition.
The one rule that saves money
When you're between two sizes, take the bigger one. The step-up from a 15 to a 20-yard typically costs $40–$80; overfilling a 15 and needing a second haul costs a full second rental. Nobody has ever been mad at a dumpster with a little room left over.
Watch the weight limit, not just the walls
Every container carries an included tonnage — typically 2–3 tons on mid-sizes — and heavy materials hit it long before the container looks full. Shingles, tile, plaster, and anything wet are the classic overweight culprits. If your debris is heavy, say so in your quote request: the right answer might be a smaller heavy-debris box, which is cheaper than an overage fee.
