How We Calculate Your Ideal Bin Size
The right dumpster size balances three factors: the volume of debris, the weight of debris, and the physical footprint of the container.
Volume
Each project type and scale maps to a measured volume tier. A 10-yard bin holds roughly 3-4 pickup truck loads, a 20-yard bin holds about 8 loads, and a 40-yard dumpster holds 12 or more.
Weight
Heavy masonry materials like concrete, dirt, and brick exceed highway axle limits in larger containers. The calculator locks heavy debris to a dedicated 10-yard clean-fill bin for safe transport.
Roofing Math
One roofing square (100 sq ft) of tear-off produces about 0.5 loose cubic yards. The calculator snaps your roof area to the nearest tier with padding for multiple shingle layers or overlapping bundles.
Heavy-debris safety override: heavy masonry materials exceed legal transport highway axle limits in larger containers. You must use a dedicated 10-yard mini bin to prevent structural overloads, regardless of your project volume.
