Dumpster Sizes & Dimensions Guide
Roll-off dumpsters are measured in cubic yards — the volume of debris they hold. Choosing the right size helps you avoid paying for unused space or getting hit with overage charges for exceeding your container's limit.
| Size | Approx. Dimensions (L x W x H) | Typical Weight Allowance* | Best For |
|---|---|---|---|
| 10 Yard | ~12 ft x 8 ft x 3.5 ft | ~1–2 tons | Small cleanouts, single-room remodels, yard debris |
| 15 Yard | ~16 ft x 8 ft x 4 ft | ~1.5–3 tons | Garage cleanouts, small roofing jobs, mid-size decluttering |
| 20 Yard | ~22 ft x 8 ft x 4.5 ft | ~2–4 tons | Kitchen/bath remodels, larger cleanouts, flooring removal |
| 30 Yard | ~22 ft x 8 ft x 6 ft | ~3–5 tons | New construction, additions, whole-house cleanouts |
| 40 Yard | ~22 ft x 8 ft x 8 ft | ~4–6 tons | Large commercial builds, major demolition, bulky low-density debris |
*Weight allowances vary significantly by provider, region, and local landfill tipping fees. Always confirm the included weight limit and overage rate before booking. See our pricing guide for more on how weight affects cost.
Not sure which size to pick? As a general rule of thumb, a 10–15 yard container suits most single-room projects, 20 yards fits most mid-size remodels, and 30–40 yards fits construction, additions, or whole-property cleanouts. When in doubt, sizing up slightly is usually cheaper than paying for a second trip.
