What Size Dumpster Do I Need?

Every call we get starts the same way: someone describes a job and asks which dumpster they need. It is a fair question, and it is also the one homeowners and contractors get wrong most often — not because the sizes are confusing, but because South Florida debris behaves differently than the internet's generic sizing charts assume. We run five sizes out of our yard near downtown Fort Lauderdale, and this guide walks through each one honestly, including where volume alone will steer you wrong.

The five sizes we deliver

All five containers use the same industry-standard footprint family, just taller as you go up. Here is what actually shows up in your driveway.

Notice the 20, 30 and 40 yard containers share the same 22-foot footprint and only grow taller. That matters for placement — a 30 yard box does not need more driveway length than a 20, just more headroom for loading, which is worth knowing if your access is tight but you genuinely have a large-volume job.

Volume is only half the story in South Florida

Most sizing charts online talk purely in cubic yards, as if a yard of debris weighs the same everywhere. It does not. Two things about South Florida make weight the real limiting factor more often than volume:

• CBS construction debris is dense. Concrete block, stucco, and tile are the default building materials here, not wood framing. A 15 yard container full of stucco scraps and broken tile can hit its weight allowance long before it looks full. If your project involves demoing a CBS wall, tearing off tile flooring, or pulling old stucco, size up from what pure volume would suggest, or ask us about a dedicated smaller box you swap more often — see our concrete and stucco debris guide for the specifics.
• Storm and yard debris is often wet, and wet is heavier than it looks. Downed palm fronds, waterlogged drywall, and rain-soaked landscaping trim can weigh two to three times what the same pile weighs dry. If you are loading after a storm or clearing a yard mid-wet-season, do not judge the container by how full it looks — judge it by how heavy it is getting.

This is the single biggest reason a sizing conversation with us beats guessing from a chart: we ask what the material actually is, not just how big the pile looks, before we recommend a size.

Matching size to the job

Here is how we actually field these calls, broken down by project type.

Garage, attic or single-room cleanout: A 10 yard is almost always right. It fits in a condo courtyard or a tight Sailboat Bend driveway, and most cleanouts of this scale simply do not generate enough weight or volume to justify anything larger.

Bathroom remodel or small yard project: A 15 yard covers most single-bathroom gut jobs, fence removals, and moderate landscaping cleanups. It is our most-requested size for weekend DIY projects for a reason.

Kitchen remodel, roof replacement, or whole-house decluttering: The 20 yard is the workhorse. It is large enough for most asphalt-shingle roof tear-offs and kitchen demos, and it still fits the standard residential driveway without special placement planning. If you are specifically pricing a roof job, our roofing tear-off sizing guide gets more granular by roof size.

Additions, full interior gut jobs, or new-construction cleanup: Step up to a 30 yard. Framing offcuts, drywall scraps, and packaging from a new build in Coral Springs or Plantation add up fast, and contractors on a schedule would rather swap a smaller box twice than wait on a special order for a bigger one mid-project.

Commercial teardown or large-scale demolition: The 40 yard is built for volume over weight-dense material — think framing, packaging, and bulky commercial debris rather than solid concrete. We will flag it if your job is actually a weight problem in disguise, because a 40 yard full of concrete rubble is not a realistic ask for any hauler.

When two smaller boxes beat one big one

It sounds counterintuitive, but for dense material — old concrete driveway sections, full tile tear-outs, stucco demo — we often steer customers toward a 15 or 20 yard container with a scheduled swap rather than a single 30 or 40. A smaller box gets picked up, weighed, and dumped before it hits a problematic weight point, then we bring an empty one back. On a multi-day renovation this keeps the job moving instead of stalling out waiting on an oversized container that was never going to get loaded to its rim anyway.

Access matters as much as size

Before you commit to a size, walk your actual drop zone. Measure the width of your driveway entrance, note any low tree branches or power lines, and check whether the delivery truck has a straight shot in or needs to back in from the street. Our drivers protect driveways with boards on every drop, but they still need honest clearance numbers up front — a 22-foot container needs 22 feet of relatively straight approach, not 22 feet of curb-to-curb street frontage.

Common sizing mistakes we see

A few patterns come up over and over, and each one is avoidable once you know to look for it.

• Sizing off the room, not the material. A single bathroom demo sounds small, but if the job includes ripping out a tiled shower surround and a cast-iron tub, the weight adds up faster than the room size suggests. We ask what is coming out, not just how big the room is.
• Forgetting the yard debris pile that has been sitting for weeks. Storm-downed branches and palm fronds that sat through a few rain events are heavier and often already starting to break down, which changes both the weight and how they load. Fresh-cut debris and rain-soaked debris are not the same job.
• Assuming bigger is always safer. A 40 yard container full of packaging and framing offcuts is fine. A 40 yard container someone tries to fill with broken concrete is a weight problem waiting to happen, and it is also simply more container than most residential jobs need. Right-sizing saves a wasted trip as often as it saves an overage.
• Not accounting for multiple trades on one job. If a remodel involves a plumber, an electrician, and a general contractor all generating debris on different days, one container might need to be swapped partway through rather than sized enormous from day one. We can schedule a swap around your trade calendar instead of guessing at total volume up front.

How weight allowances actually work

Every container we deliver comes with a weight allowance built into the flat rate, scaled to the size. Go over it and there is a per-ton overage rather than a surprise renegotiation — but the honest goal on our end is to size you correctly the first time so overage never comes up. That is a different incentive than a generic online booking tool has, and it is part of why we would rather ask two extra questions on the phone than let a self-serve calculator guess for you. For more on how the flat rate itself is built — size, weight allowance, rental period, and distance — see our pricing structure guide.

Still not sure? Call instead of guessing

Sizing charts are a starting point, not a final answer. When you call (754) 354-3921, we ask three questions — what material, roughly how much, and where it is going to sit — and we will tell you the size, not just suggest one. That is faster and more accurate than any online calculator, and it is why most of our repeat customers stop measuring and just call.
