If you've never rented a roll-off before, the size question feels bigger than it is. I get calls every week from folks out in Wilson County standing in their driveway, tape measure in hand, trying to guess whether the garage cleanout is a 10-yard job or a 20. Here's the honest truth after years of dropping cans all over Lebanon and the surrounding Middle TN towns: most people either overthink it or underestimate it, and both cost money. Overthink it and you pay for air. Underestimate it and you're calling me for a swap-out halfway through a Saturday demo. Let me walk you through how I'd size it if you were my neighbor.
Start With What You're Throwing Away, Not the Pile
The single most useful thing you can do before you call anyone is name the job. "A dumpster" isn't a job. "Gutting a 1990s master bath down to the studs" is a job. "Clearing out my late father's garage and the shed behind it" is a job. "Tearing off 22 squares of three-tab shingle" is a job. Once you can describe the work in a sentence, the size almost picks itself, because different debris behaves completely differently.
Volume is what you see. Weight is what you pay for when you cross the line. A 20-yard box packed with couch cushions and cardboard might roll away at 1,500 pounds. That same box filled to the brim with wet drywall, old tile, and a couple of cast-iron tubs can hit 8,000 and blow past your tonnage allowance. So we're really answering two questions at once: how much space do you need, and how heavy is it going to be?
The Size-by-Size Breakdown
Roll-off dumpsters are measured in cubic yards. One cubic yard is a cube three feet on every side. When I say "10 yard," I mean the container holds roughly ten of those cubes. Here's how the four common sizes actually play out on real Lebanon jobs.
10-Yard Dumpster
This is the small, low-profile can. It's about 12 to 14 feet long, 8 wide, and only around 3.5 feet tall, which is exactly why people love it for heavy stuff. You can practically step over the wall. Ten yards holds roughly three to four pickup truck loads. It's my go-to for a single-room renovation, a small bathroom tear-out, a modest garage or basement cleanout, or the classic concrete and dirt job. Because it sits low and stays under most weight limits, it fits on tight suburban driveways without eating the whole thing. If you're doing anything with heavy debris, this is usually the size, even when the pile looks small. Learn more on the 10-yard dumpster page.
15-Yard Dumpster
The 15 is the tweener, and honestly it's underrated. It splits the difference between the 10 and the 20, which makes it perfect for jobs that are too big for the little can but don't justify the full 20. Think a good-sized deck removal, a large bedroom plus closet gut, flooring across a couple of rooms, or a serious "we're finally dealing with the attic and the basement" household purge. It still keeps a reasonable footprint on the driveway and handles a mix of moderately heavy material better than a 20 you're afraid to fill.
20-Yard Dumpster
This is the workhorse and the one I drop most often around Lebanon. Twenty yards is roughly six pickup loads. It's the sweet spot for a whole-room-plus renovation, a big garage and shed combo, whole-house flooring, or a moving-related clear-out where you're tossing furniture, boxes, and years of accumulated stuff. It's tall enough to swallow bulky items but not so long it swallows your driveway. For a typical Middle TN three-bedroom home doing a real decluttering push, the 20 is where I'd start the conversation. See the 20-yard dumpster page for dimensions.
30-Yard Dumpster
Now we're into contractor and major-project territory. Thirty yards is a tall box, roughly six feet high, holding around nine pickup loads. This is for whole-home renovations, new construction cleanup, large commercial jobs, big additions, or when you're clearing an entire estate at once. The height is the trade-off: it holds a lot, but you're lifting debris higher to get it over the wall, so it's better suited to light and bulky material than dense heavy waste. If you're a builder running a jobsite, this is likely your default. Our construction dumpster rental service is built around these.
| Size | Best For | Approx. Truck Loads | Height |
|---|---|---|---|
| 10 yard | Single room, small bath, concrete/dirt | 3-4 | ~3.5 ft (low) |
| 15 yard | Deck removal, multi-room flooring, big purge | 4-5 | ~4 ft |
| 20 yard | Whole-room reno, garage + shed, moving | ~6 | ~4.5 ft |
| 30 yard | Whole-home reno, new construction, estates | ~9 | ~6 ft (tall) |
Weight Limits: The Part Everyone Forgets
Every roll-off comes with an included tonnage allowance, and going over it costs extra per ton. That's not a gotcha; it's physics and road law. Our trucks have legal axle limits, and the landfill charges us by weight. A rough rule of thumb for the sizes above: a 10 typically carries 2 to 3 tons included, a 15 around 3, a 20 around 3 to 4, and a 30 around 4 to 5. Always confirm the exact number when you book, because it varies by material and by what the local transfer station is doing that season.
Here's the practical takeaway. Household junk, furniture, cardboard, and general remodel debris are light for their volume, so you'll run out of space long before you run out of weight. Go bigger on volume there. But dense material flips the math entirely, and that's where people get burned.
Heavy Debris: Concrete, Dirt, and Roofing
If your load includes concrete, brick, block, asphalt, dirt, gravel, or roofing shingles, throw out everything I just said about going bigger. Heavy debris will max out the weight limit when the box is only a third or halfway full. I've seen a 20-yard can look practically empty and still be too heavy to legally haul because someone filled the bottom with broken driveway.
For those jobs, we almost always use a 10-yard can, and often we'll cap it at a fill line. Some materials we ask you to keep clean and separated, because mixed heavy loads can't always go to the same facility. A few specifics from experience:
- Concrete and asphalt: Small can, hard fill limit. A full 10-yard of concrete is extremely heavy. Don't guess; ask us for a clean-concrete rate, which is often cheaper because it can be recycled.
- Dirt, sand, and gravel: Same story. These are deceptively heavy when wet. Keep it separate from your other debris if you can.
- Roofing shingles: A single square of asphalt shingle weighs a couple hundred pounds. A typical Wilson County re-roof of 20 to 30 squares needs its own dedicated can, and I'd size that as a 15 or 20 with the understanding that weight, not volume, is the ceiling.
The rule I give everyone: when it doubt on heavy material, go smaller on the box and honest on the weight. It's cheaper than an overage. If you're not sure what your debris weighs, describe it to us and we'll size it for you. Not sure what's even allowed in the can? Read what can go in a dumpster before you start loading.
Don't Forget the Driveway and the Approach
This one's specific to how a lot of Middle TN homes are laid out. Plenty of driveways out here are on a slope, or narrow, or have a low-hanging limb or a basketball hoop right where the truck needs clearance. A roll-off truck needs a straight, fairly level shot to set the can down and pick it back up, and roughly 60 feet of length plus overhead clearance to work. Before you decide on a 30-yarder, walk your driveway and picture a truck backing in. If it's tight, a 20 or two smaller hauls may actually be the smarter play. We'll always put boards down to protect the surface, but the geometry has to work.
Also think about where the can sits relative to your work. You want it close enough to walk debris to it, but not blocking the garage you're emptying or the door the trades need. A little planning here saves a lot of steps over a weekend.
How I'd Size a Few Common Lebanon Jobs
- Single bathroom remodel: 10 yard. Tile and a cast-iron tub add up fast, so the low can and its weight allowance fit perfectly.
- Two-car garage and shed cleanout: 20 yard. Bulky, light, lots of it. Space is your limit, not weight.
- Kitchen gut plus new flooring: 15 or 20 depending on whether you're pulling old tile. Tile pushes you toward being weight-conscious.
- Re-roof, 25 squares: Dedicated 15 or 20, weight-limited. Keep it shingles-only.
- Whole-house renovation: 30 yard, or a 20 you swap out. Builders usually run a roll-off rental for the duration.
- Broken-out patio, concrete only: 10 yard, clean-concrete rate. Never mix it with wood or trash.
When You're Truly Torn Between Two Sizes
Ninety percent of the time, if you're stuck between two sizes and the debris is light household or remodel material, go up one. The price difference between a 15 and a 20 is small compared to the cost and hassle of a second haul or an overloaded can we can't pick up. But if the debris is heavy, do the opposite: stay smaller and keep a second load in your back pocket. Weight overages are where budgets quietly blow up.
And if you genuinely can't tell, just call and describe the job. Tell me the rooms, the material, and roughly the square footage, and I'll size it in about ninety seconds. That's the whole reason we're local. You can reach us at (615) 257-9262, or see everything we offer on the services page.
The Bottom Line for Lebanon Homeowners and Contractors
Name the job, respect the weight, and check your driveway. Do those three things and the size question stops being intimidating. Light and bulky, go bigger on volume. Heavy and dense, go smaller and watch the tonnage. When you're between sizes on ordinary debris, round up; on heavy debris, round down. That's the entire framework I've used on thousands of drops around Wilson County.

Frequently Asked Questions
What size dumpster do I need for a single room or bathroom remodel?
A 10-yard dumpster is almost always the right call for a single-room or bathroom remodel. The low walls make it easy to load, and its weight allowance handles the tile, old tub, and drywall that these jobs produce. If you're gutting more than one room at once, step up to a 15-yard.
Can I put concrete or dirt in any size dumpster?
Technically yes, but you shouldn't put heavy debris in a large box. Concrete, dirt, brick, and asphalt are so dense they hit the weight limit when the can is only a third full, so we use a 10-yard for those loads and often apply a fill line. Ask about our clean-concrete rate, since separated concrete can be recycled and usually costs less to haul.
What happens if I go over the weight limit?
Every rental includes a set tonnage allowance, and anything over that is billed per additional ton. It's not a penalty, it's what the landfill charges us by weight plus legal road limits on our trucks. The best way to avoid overages is to describe your debris honestly when you book so we size the can correctly and, for heavy material, keep it smaller.
How much room do I need on my driveway for a roll-off dumpster?
Plan on roughly 60 feet of straight, fairly level space plus overhead clearance so the truck can set the can down and pick it up. Many Middle TN driveways slope or have a tight approach, so walk yours before choosing the biggest size. We always put down boards to protect the surface, but the truck still needs a clear, straight shot.
Should I round up or round down when I'm between two sizes?
It depends on the debris. For light, bulky household or remodel material, round up a size, because a second haul costs more than the small price bump. For heavy material like concrete, roofing, or dirt, round down and keep a second load in reserve, since weight is your real limit. When in doubt, call us and we'll size it in about a minute.
