Dumpster sizes explained
Roll-off dumpsters come in five standard sizes. They share the same 8-foot width — what changes is length and height, which sets both volume and how much driveway you need. Here is each size at a glance.
10 yard
Dimensions ~12' × 8' × 3.5', about 2 tons included, ~3 pickup loads. The smallest can and the only one for heavy material — concrete, dirt, brick. Also great for small cleanouts and bathroom remodels. Fits a typical driveway with room to spare.
15 yard
Dimensions ~14' × 8' × 4.5', about 2.5 tons, ~4–5 pickup loads. The flexible middle size — single-layer roof tear-offs, kitchen remodels, and medium cleanouts. Fits a standard driveway.
20 yard — most popular
Dimensions ~16' × 8' × 5', about 3 tons, ~6–8 pickup loads. The right call for roughly 60% of residential jobs: two-layer roofing, full remodels, and large cleanouts. Fits most residential driveways.
30 yard
Dimensions ~22' × 8' × 6', about 4 tons, ~9–12 pickup loads. Built for volume — whole-house cleanouts, new construction, and major renovations. Needs full clearance and ~60 ft of straight access to drop.
40 yard
Dimensions ~22' × 8' × 8', about 5 tons, ~12–16 pickup loads. The largest can, for commercial jobs and big construction. Reserve it for bulky, lighter debris — never concrete or dirt, which would exceed road weight long before it is full.
Frequently asked
Roll-off dumpsters come in 10, 15, 20, 30, and 40 cubic-yard sizes. The 20-yard is the most popular for residential work.
About 16 ft long, 8 ft wide, and 5 ft high — roughly 6–8 pickup-truck loads of capacity, with about 3 tons of weight included.
Both are 22 ft long and 8 ft wide; the 40-yard is taller (8 ft vs 6 ft), so it holds more volume. The 40-yard suits bulky light commercial debris, while the 30-yard handles most large residential jobs.
