Skip & Dumpster Size Calculator

Work out the container size a job's waste needs, and check it against the weight limit before the volume runs out.

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

With the figures above, the container volume required comes to 6 m³. Behind that figure, volume this container can take at the weight limit is the biggest single quantity at 28.6 m³; start there if the total looks wrong. Note that loose waste volume sits at the low end of the range this calculator was checked against, so treat the output as indicative rather than settled. The method behind this is well established, though site conditions and material batches will move it somewhat. This is calculated for United States and cites IRC 2024. Building in another market?

Estimated cost — your price

This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Regulatory standards & verification citations

  • Typical loose waste densities: mixed construction 200-300 kg/m³; soil and rubble 1400-1600 kg/m³; timber 200 kg/m³
  • Skips and roll-off containers carry a weight limit as well as a volume; heavy waste reaches the weight limit first

Frequently asked questions

Why does my skip look half empty and get refused?
Because you filled it with rubble. At 1500 kg/m³ a heavy waste stream reaches an 8-tonne limit at about 5.3 m³ — roughly half a large skip. Hire companies size heavy-waste containers small for exactly this reason, and the breakdown shows the volume your limit actually allows.
How much waste does a strip-out actually produce?
More than the material occupied in place — commonly one and a half to two times. A tonne of plasterboard broken off a wall takes far more space than it did on the wall. Estimate the installed volume and then increase it, rather than measuring the room.
Can everything go in one container?
No. Plasterboard is separated in several jurisdictions because it produces hydrogen sulphide in landfill; paint, solvents and batteries are hazardous waste; and anything containing asbestos must be handled by a licensed contractor and never put in a general skip. Segregating is also usually cheaper than mixed disposal.
