Dumpster Size Guide: 10, 15, 20, and 30 Yard Dumpsters Compared

Quick answer: on the South Shore, a 15-yard dumpster handles the vast majority of residential jobs, and a 20-yard covers almost everything else - the 10-yard and 30-yard you've seen advertised elsewhere are mostly solving problems you probably don't have. (Yes, we just answered the whole "which size do I need" question in one sentence. Keep reading anyway - the part where people overpay for the wrong size is the part that actually saves you money.)

Every roll-off dumpster company lists the same four sizes - 10, 15, 20, and 30 yard - and every page that compares them reads like it was written by someone who's never actually dropped one in a South Shore driveway. Narrow lots, tight side yards, and a steady mix of renovation debris, cleanout junk, and yard waste mean the "right" size here isn't always the one a generic chart recommends. This guide walks through what each size actually holds, what we see it used for across Hull, Hingham, Cohasset, and the rest of the South Shore, rough pricing by size, and - more usefully - when sizing up or down from the default actually makes sense.

Dumpster Sizes at a Glance

Here's the short version before we get into each size individually. "Truck loads" assumes a standard full-size pickup bed, heaped.

10-Yard Dumpster: What It's For (and Why We Don't Stock One)

A 10-yard is the smallest size most companies offer - roughly 14 feet long, holding about 4-5 pickup truck loads or 50-70 trash bags. It's genuinely the right call for a few narrow situations: a single small room with heavy, dense debris like concrete, brick, or tile, where weight fills the container long before volume does.

Here's the part most size-comparison pages skip: for most South Shore homeowners, a 10-yard isn't actually the cheaper option it looks like on paper. The delivery truck, the driver, and the trip to the transfer station cost roughly the same whether the box is 10 yards or 15 - so a 15-yard often runs close to the same price while holding 50% more. If you're not dealing with pure heavy debris, size up by default.

15-Yard Dumpster Rental South Shore MA: Our Most-Booked Size

The 15-yard is the size we rent out more than any other, and it's not close. At roughly 16 feet long and holding about 6 pickup truck loads, it's sized for single-room cleanouts, a garage or basement clear-out, or a small renovation like a bathroom gut or a deck tear-off - and it still fits comfortably in most standard driveways.

15 yards is the right size for most residential cleanouts - that's not a hedge, it's the default we'd give almost every homeowner who calls us. Oversizing to "be safe" just means paying for airspace you never fill; the smarter move is sizing to the job in front of you and upgrading only if you're clearly past the halfway point before you're done loading.

20-Yard Dumpster Rental South Shore MA: When You Need More Room

The 20-yard is our other size, and it's the right call once a job outgrows a 15 - whole-house cleanouts, roofing or siding jobs, construction debris, or a renovation touching more than one room. At roughly 22 feet long and holding about 8 pickup truck loads, it's noticeably bigger than a 15 without being hard to place in a typical residential driveway.

If you're genuinely unsure between a 15 and a 20, the honest tell is the project itself: one room or one system (garage, basement, a single bathroom) usually fits a 15; anything touching the whole house, the roof, or multiple rooms at once usually needs a 20. When in doubt, describe the job when you call - we'd rather talk you into the right size than the bigger one.

30-Yard Dumpster Rental South Shore MA: Rare, and Here's Why

A 30-yard is a real size in the industry - roughly the same footprint as a 20 but taller, built for major demolition, large commercial cleanouts, and new-construction debris. It's standard equipment for a big job site, and if that's genuinely your situation, it's worth asking any South Shore hauler whether they can source one or arrange it through a partner.

For a typical homeowner, though, a 30-yard is almost always overkill. If you've searched "30 yard dumpster rental South Shore MA" because a whole-house renovation or a major cleanout feels huge, call first and describe the scope - in our experience, most of those jobs land comfortably in a 20-yard once you actually start counting rooms and loads instead of guessing from how overwhelming the project feels.

The Most Common Sizing Mistake (and How to Avoid It)

The mistake isn't usually under-ordering - it's over-ordering "to be safe," which just means paying for cubic yards that sit empty. The opposite mistake, ordering too small, is worse in a different way: once a dumpster is full, you're either paying for a second pickup and drop-off or cramming debris above the fill line, which most haulers won't take on the truck at all.

• Count rooms and loads, not square footage. A big, lightly-cluttered house can fill less space than a small, packed one.
• Separate heavy debris from bulky debris. Concrete and shingles hit the weight limit fast; furniture and boxes hit the volume limit fast. Know which one you've got more of.
• When you're between two sizes, size up one step - not two. The jump from a 15 to a 20 is a few more truck loads of headroom; jumping straight to a 30 for a residential job is almost always unnecessary cost.

Weight Limits and Overage Fees

Every roll-off rental, regardless of size, comes with two limits: a volume limit (the cubic yards) and a weight limit (usually a few tons, depending on size and provider). Go over the included weight allowance and you'll owe a per-ton overage fee - typically $40-$100 per ton industry-wide, though it varies by hauler.

This is where dense materials catch people off guard: shingles, concrete, dirt, and wet debris are heavy enough to hit a weight limit while the container still looks half-empty. If a job is mostly that kind of material, say so when you book - it changes which size actually makes sense far more than the room count does.

Driveway Placement and Permits

Most South Shore homeowners never think about permits because they don't need one - if the dumpster sits entirely on your own driveway or property, that's generally all you need to worry about. Where it gets more complicated is when a driveway is too short or too narrow and the box has to sit partly or fully on the street.

Massachusetts towns generally follow the same pattern here: private property placement doesn't require a permit, but putting a dumpster on a public street does, through a street occupancy or obstruction permit from the town's DPW. Boston's own guide to getting a street occupancy permit lays out the general process, and most South Shore towns run a similar system through their own DPW - worth a quick call to your town before the truck shows up if your driveway's on the short side.

Dumpster or Full-Service Junk Removal?

A dumpster makes sense when you're sorting and loading it yourself over several days - a renovation generating debris as you go, or a cleanout you want to tackle at your own pace. If you'd rather point at what goes and let a crew do the lifting in one visit, our junk removal service is the faster path, and our pricing guide breaks down what that typically runs. Not sure which fits? Describe the job when you call - we'll tell you straight.
