Not sure? The dumpster size calculator estimates volume and tons from your project.

Weight, not volume, is usually the real limit

A 20-yard full of shingles weighs far more than a 20-yard full of furniture. US EPA conversion factors: composition roofing ~731 lbs per loose cubic yard, concrete ~860, dirt and sand ~929, mixed C&D ~417, loose household waste 250-300. Ten yards of dirt is about 4.6 tons - more than most 20-yard allowances - which is why haulers often limit dirt and concrete to 10-yard containers.

Which size do you need?

Pick the project, enter its size, and get a container size plus an estimated weight. Weights use US EPA volume-to-weight factors for loose debris.

Estimate only. Heavy debris (dirt, concrete, shingles) usually hits the weight limit before the container is full, and many haulers restrict heavy loads to 10-yard containers. Confirm with your hauler.
