Roll-off containers come in a handful of standard sizes, named for how much they hold. Picking one is mostly a matter of turning your project into an estimate of volume and weight. This guide explains how dumpster rental sizes work, what each size is commonly used for, and how to estimate without guessing.
One call or a short form. An independent local provider quotes the size, the drop spot and the dates.
Dumpster Rentals Louisville is an independent referral service, not a dumpster company. Calls and form requests go to an independent local roll-off provider that quotes the job, drops off the container and hauls it away.
What the yard in a dumpster size means
A size such as 20 yard means 20 cubic yards of space. One cubic yard is a box three feet long, three feet wide and three feet high: 27 cubic feet. That gives each common size a simple volume:
| Size | Volume in cubic feet | Commonly used for |
|---|---|---|
| 10 yard | About 270 | Garage or basement clear-outs, a small bathroom, heavy loads such as brick or dirt where accepted |
| 15 yard | About 405 | Larger cleanouts, flooring from several rooms, a small kitchen |
| 20 yard | About 540 | A kitchen remodel, a typical roof, a whole-house cleanout of light items |
| 30 yard | About 810 | Major renovations, additions, large estate cleanouts |
| 40 yard | About 1,080 | New construction, commercial cleanouts, big volumes of light debris |
Not every provider carries every size, and some carry sizes in between. Length, width and wall height vary by maker and by provider too, which is why this site does not print them. If your driveway or lot is tight, ask the provider for the exact footprint of the container it would bring.
How big is a 10 yard dumpster?
A 10 yard dumpster holds about 270 cubic feet. It is the smallest size many roll-off providers offer and the one most often chosen for short driveways, single rooms and heavy material. Its low walls make it easier to throw debris over the side, and its smaller footprint leaves room beside it on a driveway. The small dumpster rental page covers 10 and 15 yard containers in detail.
How big is a 30 yard dumpster?
A 30 yard dumpster holds about 810 cubic feet, three times a 10 yard. It is a common choice for remodels that gut several rooms at once, additions, and cleanouts of whole houses with furniture. It is long and tall, so it needs a long driveway or a lot, and loading it usually means walking debris in through the door at one end.
Weight: the limit people forget
Every container comes with a weight allowance set by the provider, and charges usually apply above it. Light, bulky debris such as furniture, boxes and framing scraps fills a container by volume first. Dense material such as concrete, brick, tile, plaster, dirt, rock and roofing shingles reaches the weight allowance first, often long before the container looks full. For heavy loads, providers often recommend a smaller container, sometimes with a fill line.
Good to know
Wet debris weighs more than dry debris. A tarp over the container between loading sessions helps where the provider allows it.
How to estimate your load
- List what is coming out, room by room: cabinets, flooring, drywall, furniture, fixtures.
- Note the heavy items separately: tile, plaster, brick, concrete, shingles, dirt.
- Picture the pile in the driveway, then compare it with the volumes above. A pickup truck bed piled to the top of its sides is a rough mental unit for many people.
- Tell the provider both lists. It can suggest a size, a weight allowance and whether heavy material should go in its own container.
When in doubt between two sizes, ask what it would cost to swap a full container for an empty one versus booking the larger size from the start. Either can make sense, depending on how long the job runs.
Fitting the container to the space
The truck matters as much as the container. A roll-off truck needs a straight approach, firm ground and clear space overhead to tilt its bed. Measure the spot, look up for wires and branches, and move cars before the drop. If the container has to go in the street in Louisville Metro, it needs a Dumpster/Pod Permit; see the dumpster permit page.
Still between sizes? Call or send the form and describe the job; an independent local provider can suggest the container that fits.
Questions people ask
What dumpster size do most homeowners rent?
For a single room or a garage, 10 or 15 yards; for a kitchen, a roof or a whole-house cleanout, 20 yards; for major renovations, 30 yards. The load decides it.
Why does the weight allowance matter?
Heavy debris can reach the provider’s weight allowance before the container is full, and charges usually apply above it.
