Dumpster Size Calculator
Pick a 10, 15, 20, 30, or 40 yard dumpster from your project, with typical rental cost, extra days, and weight cap.
How to use this dumpster size calculator
Dumpsters are sold by cubic yards of volume, not by how full they look from the street. Roofs and dirt are heavy — you can hit the weight cap before the box is full, and overage fees hurt. Mix rules matter: no paint, fuel, or dirt in a construction box unless the hauler says so.
This dumpster size calculator maps common jobs to a size and a typical 7-day rental. Permit fees for street placement are extra. Book drop-off so the driveway still works; 20-yard boxes are the usual homeowner sweet spot.
Formula
Worked example

Often 2 tons on a 10-yard, ~4 tons on a 20-yard, more on 30–40. Dirt and shingles hit caps fast.
