Describe your project and debris, and the calculator recommends the right dumpster (10, 20, 30, or 40 yard) for the job.

Most “it didn't fit” stories trace back to one of these oversights.
Frequently asked
A 10-yard dumpster handles a standard kitchen remodel (cabinets, countertops, flooring, drywall). If you're also replacing appliances or doing structural work, go with a 20-yard.
01A 10-yard holds ~3 pickup truck loads (small remodel or cleanout). A 20-yard holds ~6 loads (large remodel, deck removal). A 30-yard holds ~9 loads (new construction debris, whole-house cleanout). The 40-yard is for commercial demolition.
02Estimate the debris in pickup truck loads, because one load is roughly 3 cubic yards, then match: 3 loads to a 10-yard, 6 loads to a 20-yard, 9 loads to a 30-yard. Then check the material. Concrete, dirt, brick and roofing reach the weight limit long before the volume limit, and for those you size down and take two loads instead.
03Multiply the debris length, width and height in feet and divide by 27 to get cubic yards, then add about 15 percent because debris does not pack tidily. For a demolition, calculate the material volume rather than the finished room: a 10 x 12 ft room stripped back to the studs produces far more than the 120 sq ft of floor suggests.
04It depends on the material, which is why weight rather than volume is the usual limit. A 10-yard of household junk runs 1 to 2 tons, the same container full of roofing shingles runs 4 to 5 tons, and full of concrete it exceeds 10 tons. Most rentals include 1 to 2 tons and charge per ton above that, so heavy debris is the case where you call before you fill.
