Dumpster size guide
- 10-yard dumpster: Small renovation, 2-3 tons limit
- 20-yard dumpster: Medium remodel, 3-4 tons limit
- 30-yard dumpster: Large renovation, 4-5 tons limit
- 40-yard dumpster: Major construction, 5-6 tons limit
Weight limits vary by provider. Heavy materials like concrete, brick, and dirt may reach weight limits before the dumpster is full.
Worked example
For example, for a 6×4×3 ft pile of debris from a bathroom renovation:
- Volume = 6 × 4 × 3 = 72 cu ft
- Cubic yards = 72 ÷ 27 = 2.67 yd³
- Recommended dumpster: 4-yard minimum (holds 4 yd³)
- Common debris: drywall, wood, tile, fixtures, and packaging
- Heavy materials like concrete may need a smaller dumpster
Common mistakes
| Mistake | Why it matters |
|---|---|
| Overfilling the dumpster | Debris should not extend above the rim — overloaded dumpsters may be refused for pickup |
| Putting prohibited items inside | No paint, chemicals, tires, batteries, or electronics in standard dumpsters |
| Underestimating debris volume | A small bathroom renovation can easily fill a 4-yard dumpster — size up if unsure |
