Two Different Limits: Cubic Yards and Tons
Almost every call we get at Blue Fox Dumpster Rental Aurora starts the same way: “What size dumpster do I need?” People usually expect a single number to settle it. In practice, every roll-off box has two separate ceilings, and they don’t move together.
The first ceiling is volume — how many cubic yards of space are inside the box. The second is weight — how many tons the box, and the truck hauling it, is allowed to carry once it’s full. For most household projects — old furniture, cardboard, drywall scraps, broken toys, yard waste, general construction debris — you run out of room long before you get close to the weight limit. The box fills up visually, and that visible fullness is the number that decides your size.
For dense material — concrete, brick, tile, asphalt, landscape rock, xeriscape stone, packed dirt, wet soil — the opposite happens. The truck hits its weight limit while the container still looks a third empty. Renting a bigger box doesn’t solve that problem, because the weight allowance built into each size grows much more slowly than the visible airspace does. A 40-yard box holds four times the volume of a 10-yard, but it only carries about three times the tonnage.
This guide walks through all five sizes we deliver out of our yard at 753 Salida Way, with real project examples for each, then breaks down exactly why the heaviest material on a job site is usually the reason to size down, not up. For the short version with current pricing, see our dumpster sizes page; for what things typically cost locally, see our dumpster rental cost guide for Aurora. And if you’re not sure what’s even allowed in a roll-off in the first place, it’s worth checking the rules before you book.
The 10-Yard Dumpster: Small Jobs — and Small Heavy Jobs
The 10-yard dumpster measures roughly 12 × 8 × 3.5 feet, holds about 3 to 4 pickup-truck loads of material, and includes 1 to 2 tons of weight in the rental.
For light debris, this is the size for a single-room cleanout, a small wood deck tear-off, a garage purge, or clearing out a storage shed. It’s also the size most homeowners underestimate for heavy material. A small concrete patio or walkway tear-out — say 10 × 12 feet at four inches thick — looks tiny sitting inside a 10-yard box. But plain concrete runs roughly 150 pounds per cubic foot, so a slab that size can already push toward that 1 to 2 ton allowance before the container is a third full.
That’s the pattern to remember through the rest of this guide: with concrete, brick, tile, and stone, the 10-yard is very often the correct call even on jobs that feel bigger than they are, simply because there’s nowhere for the extra weight to go. See our concrete and heavy debris removal page for more on how we price those loads, including how a reweigh works if a load comes in over the included tonnage.
The 15-Yard Dumpster: The Mid-Size All-Rounder
The 15-yard dumpster measures roughly 16 × 8 × 4 feet, holds about 4 to 6 pickup-truck loads, and includes 2 tons of weight.
On the light-material side, this size handles a whole-house carpet and pad tear-out, removal of 100 to 150 linear feet of wood fencing, a single-layer asphalt shingle tear-off on a smaller roof, or the debris from a kitchen or bathroom remodel — cabinets, drywall, old fixtures, flooring. It sits right between the 10-yard and the 20-yard, and it’s a good default when you’re not sure which of those two to book.
On the heavy-material side, the 15-yard is a good fit for a brick or paver walkway removal, a small retaining wall tear-out, or a mixed load that combines some concrete with lighter construction debris. If your roof tear-off involves multiple layers of shingles rather than one, plan on stepping up a size — shingle stacks get heavy fast, since a single square of asphalt shingles can weigh well over 200 pounds once you’re tearing off two or three layers at once.
The 20-Yard Dumpster: Aurora’s Most-Booked Size
The 20-yard dumpster measures roughly 22 × 8 × 4.5 feet, holds about 6 to 8 pickup-truck loads, and includes 2 to 3 tons of weight.
This is the size most Aurora homeowners land on. It’s big enough for a combined garage-attic-basement cleanout, a full kitchen remodel, new flooring throughout a house, or a mid-size roof tear-off in the 20 to 30 square range. It’s also the size we recommend most often for general home renovation debris that mixes drywall, cabinetry, flooring, and furniture — bulky and voluminous, but not especially dense.
Where the 20-yard gets tricky is when a remodel also includes something heavy — a tile floor tear-out, an old concrete slab, or a masonry fireplace. If those heavy items make up more than a small slice of the load, talk to us before booking; you may be better served by a smaller box for the heavy material and a separate one for everything else, rather than a single 20-yard that caps out on weight with plenty of visible room still left inside it.
The 30-Yard Dumpster: New Construction and Major Cleanouts
The 30-yard dumpster measures roughly 22 × 8 × 6 feet, holds about 9 to 12 pickup-truck loads, and includes 3 to 4 tons of weight.
This size is built for volume, not density. It’s the go-to for new home construction framing waste, room additions, whole-house cleanouts that include furniture and appliances, and larger estate cleanouts where the sheer quantity of belongings — not their weight — is the real challenge. See our new construction dumpster guide for how builders typically stage these on an Aurora job site over the course of a multi-week build.
A 30-yard is rarely the right call for a heavy-material job on its own. Filled with concrete or masonry, it would blow past its weight allowance long before the box looked full — and you’d be paying for airspace you can never legally load.
The 40-Yard Dumpster: Commercial-Scale Jobs
The 40-yard dumpster is the largest box we run, measuring roughly 22 × 8 × 8 feet, holding about 12 to 16 pickup-truck loads, and including 4 to 5 tons of weight.
This size is almost exclusively for large-volume, light-to-moderate density loads: big commercial cleanouts, large new-home builds, and demolition of framing and other light structures. Notice that even at the top of the lineup, the weight allowance only climbs from 3 to 4 tons at the 30-yard to 4 to 5 tons at the 40-yard — a modest bump for nearly double the visible airspace. That gap is exactly why volume-heavy jobs (framing, drywall, packaging, general commercial debris) belong in the 40-yard, while weight-heavy jobs never do, no matter how much space they seem to need on paper.
Side-by-Side: All Five Roll-Off Sizes
Here’s the full lineup in one place. Dimensions and load counts are approximate — actual containers vary slightly by manufacturer — but the weight allowances are what we quote on every rental agreement.
Why Concrete, Brick, and Landscape Stone Break the “Go Bigger” Rule
Around Aurora and the rest of the Denver metro area, the heaviest debris we haul isn’t usually from inside the house — it’s concrete patios and driveways, brick and paver walkways, old masonry, and increasingly, landscape rock and xeriscape stone pulled out during water-wise yard conversions. All of that material shares the same problem: it’s dense.
Plain concrete runs about 150 pounds per cubic foot. Packed soil and landscape gravel land in a similar range. Do the rough math on a 10-yard box completely full of solid concrete and you’re well past 20 tons — far beyond what the container, the delivery truck, or Colorado road weight limits allow. The Colorado Department of Transportation sets the vehicle weight and permitting rules our trucks operate under on Front Range roads. So haulers cap what you’re billed for at the stated tonnage — 1 to 2 tons on a 10-yard, for example — no matter how much visible room is left in the box once it’s loaded.
The practical upshot: for a pure concrete, brick, or tile tear-out, a small patio or walkway job almost always calls for a 10-yard, and a larger driveway or foundation job might move up to a 15-yard — but rarely further, because a bigger container’s tonnage allowance doesn’t scale proportionally with its size. You’d just be paying for empty air on top of material you’ll hit the weight limit on anyway. This is the same reasoning behind our xeriscape and landscape debris disposal guide: homeowners converting turf to xeriscape rock often need a smaller, weight-focused box for the old soil and stone, separate from any lighter plant debris.
If your project mixes both — say, a kitchen remodel that also involves ripping out a tile entry floor — tell us that when you call. It’s often cheaper and more reliable to split heavy and light debris across two appropriately sized boxes than to force everything into one large container that hits its weight cap early and gets flagged for an overage at the scale. For general background on how construction and demolition debris is tracked and diverted nationally, the EPA’s C&D debris data is a useful reference point.
Still Not Sure Which Size to Book?
Most sizing mistakes happen when someone guesses the size based on how big the project feels rather than what the debris is actually made of. When you call (720) 674-7563, we’ll ask what’s coming out — furniture and boxes, framing and drywall, or concrete and stone — and match you to the right box the first time, with a flat price and a stated tonnage allowance up front. No online guesswork, no forms, and no surprise reweigh fees because the size was wrong from the start.
Whenever you’re ready to book, give us a call — we deliver throughout Aurora and the rest of Adams County as part of our regular Denver metro routes.
