What Size Skip Bin Do I Need? A Straightforward Guide
Brett Taylor geo-content skip-sizes
After a decade of matching customers to skip bins across Australia, the single most common mistake I see is ordering a bin that's too small. Here's how to get it right the first time.
The quick rule of thumb
One cubic metre is roughly one standard box trailer load, or about four to five wheelie bins. So a 4m³ skip holds around four trailer loads. If you're standing in front of your pile of junk trying to estimate, count trailer loads and add 20% — waste always expands once you start pulling it apart.
Common sizes and what they suit
- 2m³ – 3m³ (mini skips): Small declutters, a single room, garden tidy-ups. Fits on most driveways.
- 4m³ – 6m³: The workhorse range. Kitchen or bathroom renovations, moving-house clear-outs, medium landscaping jobs. A 6m³ is our most commonly booked size for a reason.
- 8m³ – 10m³: Full house clean-ups, deceased estates, large renovation strip-outs, big green waste jobs.
- 12m³ – 15m³: Builders' waste on construction sites, office fit-out strip-outs, multi-room renovations.
- 20m³ – 30m³ (bulk bins): Commercial projects, factory clear-outs, major demolition. These are hook-lift bins and need decent access.
Why one size up almost always wins
The price difference between a 4m³ and a 6m³ bin is usually modest. The cost of ordering a second bin because the first one filled up is not — you pay a full second hire including delivery. If you're on the fence between two sizes, take the bigger one.
What the step up actually costs
Real numbers make this case better than the principle does. Checked in August 2026, the typical Melbourne 4m³ was $543 against $743 for the 6m³; in Brisbane it was $541 against $656; in Adelaide $384 against $502. Now compare that to ordering a second bin, which starts at the full from-price again — $418 in Melbourne, $519 in Brisbane, $370 in Adelaide — plus another delivery run and another wait. Every one of those step-ups is smaller than the cheapest second bin in the same city.
Those figures shift with supplier availability. Size-by-size ranges for the major cities sit on the national price index, and the home page checker prices a specific size against your postcode.
Heavy waste changes the maths
If your load includes soil, brick, concrete or tiles, size isn't the only constraint — weight is. Heavy waste is typically restricted to smaller bins or has fill-level limits, because trucks have legal lifting limits. When you search your postcode on our site, the results show which bins in your area accept heavy waste and on what terms.
