Heavy-debris rule: Concrete, dirt, and asphalt are very dense. If you fill a 20 or 30-yard container with these materials, the truck will be overweight before the container is full. For clean heavy loads, use a 10-yard lowboy dumpster.

How to Pick the Right Dumpster Size
The biggest mistake homeowners make is ordering too small and then paying for a second container. The second biggest mistake is filling a large container with heavy debris and blowing past the weight limit. Here's how to avoid both.
- 1
Estimate the debris volume
Think in pickup truck loads. A 10-yard container holds about 4 truckloads, a 20-yard about 8, a 30-yard about 12, and a 40-yard about 16.
- 2
Check the weight of the material
Concrete, dirt, asphalt, tile, and roofing shingles weigh much more than furniture and cardboard. Heavy materials need a 10-yard lowboy or multiple small loads.
- 3
Measure your driveway or placement area
Make sure the container length fits. A 20 or 30-yard dumpster is roughly 22 feet long — about the size of a standard parking space. Leave room for the truck to maneuver.
- 4
When in doubt, size up
One larger container is almost always cheaper than two smaller deliveries. If you think you'll fill 18 yards, book a 30-yard to avoid a second trip.
