Dumpster weight limits, explained
Every rental includes a weight allowance, and going over it is the most common surprise fee. Here is how much a dumpster typically includes, how much common debris weighs, and how to stay under.
How weight allowances work
A dumpster rental price includes disposal up to a set weight. When we pick up the full box, it is weighed at the disposal site. If the load is over the allowance, the extra is billed per ton at the rate in your quote, which follows local landfill rates.
Typical allowance by size
These are typical figures. Allowances vary by hauler and area, and your quote gives the exact number.
| Size | Weight typically included | Holds |
|---|---|---|
| 10-yard | 1 to 2 tons | about 3 pickup loads |
| 15-yard | 1 to 2 tons | about 4 to 5 pickup loads |
| 20-yard | 1 to 2 tons (some areas more) | about 6 pickup loads |
| 30-yard | 3 to 4 tons | about 9 pickup loads |
| 40-yard | 3 to 4 tons | about 12 pickup loads |
How much debris weighs
The U.S. Environmental Protection Agency publishes average weights for loose materials, measured per cubic yard. Real loads mix materials and have air gaps, and wet debris weighs more, so treat these as rough guides. The last two columns are simple math: what a 10-yard and a 20-yard would weigh filled level with only that material.
| Material | Per cubic yard (EPA) | Full 10-yard | Full 20-yard |
|---|---|---|---|
| Household trash and clutter (loose, mixed) | 250 to 300 lb | about 1.3 to 1.5 tons | about 2.5 to 3 tons |
| Mixed construction and demolition debris | 417 to 484 lb | about 2.1 to 2.4 tons | about 4.2 to 4.8 tons |
| Drywall (gypsum board) | 467 lb | about 2.3 tons | about 4.7 tons |
| Asphalt roofing shingles | 731 lb | about 3.7 tons | about 7.3 tons |
| Clean lumber | 169 lb | about 0.8 tons | about 1.7 tons |
| Carpet | 147 lb | about 0.7 tons | about 1.5 tons |
| Branches and stumps | 127 lb | about 0.6 tons | about 1.3 tons |
| Mixed yard waste (loose) | 250 lb | about 1.3 tons | about 2.5 tons |
| Leaves | 250 to 500 lb | about 1.3 to 2.5 tons | about 2.5 to 5 tons |
| Asphalt paving (broken) | 773 lb | about 3.9 tons | Use a 10-yard |
| Concrete (broken) | 860 lb | about 4.3 tons | Use a 10-yard |
| Dirt and sand | 929 lb | about 4.6 tons | Use a 10-yard |
| Rock and gravel | 999 lb | about 5 tons | Use a 10-yard |

What the numbers tell you
- Household junk and yard waste are light. Bulky, airy loads usually run out of space before they run out of weight.
- Drywall and shingles are dense. A 20-yard filled with drywall alone would be around 4.7 tons, and with shingles alone over 7 tons, well past a typical 1 to 2 ton allowance. That is why we size roofing and remodel jobs by weight, not just space. See roofing dumpsters.
- Heavy debris needs its own box. Even measured loose, a 10-yard of dirt would be about 4.6 tons. Solid concrete is heavier still: about 140 to 155 lb per cubic foot, or roughly 2 tons per cubic yard. That is why concrete, dirt, brick and rock go in a 10-yard filled only to the line the hauler marks. See heavy debris dumpsters.
How to stay under your allowance
- Tell us about heavy items up front: shingle layers, tile, plaster, stone counters, wet debris. We match the allowance to the job.
- Keep heavy debris out of a general load. A little concrete mixed in can push a box over.
- Cover the box when rain is forecast. Soaked debris weighs more.
- Pick a bigger size for bulky, light loads rather than overfilling a small one, and a second box (or a swap) for dense ones.
Some items can't go in at any weight. See what can't go in a dumpster.
