# Dumpster size calculator

Pick your project and the calculator returns a size, the reason, and the constraint that decides it — because whether your job is limited by weight or by volume matters more than its square footage.

Direct answer
What size dumpster do I need? There is no formula, and any site that gives you one is guessing. The calculator maps your project to the container that fits its binding constraint — the tonnage cap for dense debris, the volume for bulky debris — and shows you which one it used.

## The formula

There is no formula, and any site that gives you one is guessing. The calculator maps your project to the container that fits its binding constraint — the tonnage cap for dense debris, the volume for bulky debris — and shows you which one it used.

## Assumptions
- Recommendations assume a level load at or below the container rim, which is a legal requirement for transport rather than a preference
- Where a project sits between two sizes we recommend the larger one, because a second delivery costs more than the size upgrade
- Included tonnage varies by hauler, so the size is right and the weight allowance still needs confirming on the phone
