Sizing
What Size Dumpster Do I Need?
A practical guide to choosing between a 10, 15, 20, 30, or 40 yard dumpster for your Bethlehem, PA project. Call (484) 510-8967 and we'll help you size it right.
“What size do I actually need?” is the question we hear on nearly every call, and it makes sense — nobody wants to pay for a container that sits half empty, and nobody wants a driver to show up with something too small for the pile in the yard. We stock five sizes at our Bethlehem yard — 10, 15, 20, 30, and 40 yard — and each one has a job it does best. Here is how we walk homeowners and contractors through the decision every day.
How dumpster sizes are measured
A “yard” in dumpster terms means cubic yards of volume, not a footprint measurement. Our smaller containers — the 10 and 15 yard — run about 14 feet long, 7.5 feet wide, and roughly 3.5 to 4 feet tall. Our 20, 30, and 40 yard containers share the same 22-foot by 7.5-foot footprint and simply grow taller as the yardage increases, topping out around 8 feet on the 40 yard. That matters for placement: a taller box needs more overhead clearance, so low tree limbs, carport roofs, or power lines can rule out the tallest sizes even when the driveway itself is plenty long.
10 yard dumpster: small cleanouts and tight spaces
Our 10 yard dumpster is the one we deliver most often for single-room cleanouts, a small bathroom or kitchen remodel, a garage purge, or clearing out a shed. It fits into tighter driveways and narrow side yards, which makes it a common pick for the older, closer-set rowhomes around South Bethlehem where every foot of driveway counts. If you are hauling out furniture, old flooring, or a few weekends’ worth of yard debris, this is usually enough.
15 yard dumpster: the mid-size cleanout
The 15 yard dumpster steps up from the 10 without needing much more driveway room, since it shares the same compact footprint. We recommend it for a multi-room cleanout, a deck tear-off, a mid-size landscaping project, or a garage-plus-basement purge that’s a bit more than a 10 yard can comfortably hold.
20 yard dumpster: the most requested size
Our 20 yard dumpster is the size we deliver more than any other, and it’s a genuine middle ground — large enough for a full basement or attic cleanout, a whole-house decluttering project, a roofing tear-off on an average single-family home, or a kitchen remodel that’s pulling out cabinets and flooring together. If you’re not sure which size to book, this is usually our starting recommendation until we know more about the project.
30 yard dumpster: additions and larger renovations
The 30 yard dumpster is built for bigger jobs — a home addition, a full interior gut renovation, replacing siding on a larger house, or a commercial tenant buildout. It needs the same 22-foot footprint as our 20 and 40 yard containers but stands taller, so we’ll always confirm overhead clearance before delivery, especially on properties with mature trees or a covered carport.
40 yard dumpster: new construction and major demolition
Our largest container, the 40 yard dumpster, is the choice for new home construction, commercial buildouts, full structural demolition, or a large-scale cleanout after a fire or major water event. Because it stands the tallest of our five sizes, it needs an open, unobstructed placement area — this one is almost always a job-site placement rather than a residential driveway.
| Size | Best for | Footprint |
|---|---|---|
| 10 yard | Single-room cleanouts, small remodels, tight driveways | ~14’ x 7.5’ |
| 15 yard | Multi-room cleanouts, deck tear-offs, mid-size landscaping | ~14’ x 7.5’ |
| 20 yard | Whole-house cleanouts, roofing tear-offs, kitchen remodels | ~22’ x 7.5’ |
| 30 yard | Additions, full gut renovations, larger siding jobs | ~22’ x 7.5’ |
| 40 yard | New construction, commercial buildouts, major demolition | ~22’ x 7.5’ |
Matching size to project type
A few patterns we see constantly around Bethlehem and Northampton County:
- Estate and full-house cleanouts — usually a 20 yard, sometimes stepping up to a 30 if the home is large or has a full basement and attic both packed. See our estate cleanout checklist for a room-by-room planning guide.
- Roofing tear-offs — shingles are heavy, so size depends more on roof square footage and layer count than on visual volume. Our roofing tear-off sizing guide breaks this down in more detail.
- Historic rowhome renovation — South Bethlehem’s older rowhomes and the properties near the Colonial Industrial Quarter often call for a 10 or 15 yard specifically because of narrow lots and shared driveways; see our historic rowhome renovation debris guide.
- New construction — typically a 30 or 40 yard, often with more than one container over the life of the build. Our new construction cleanup guide covers phased ordering.
- Yard and landscaping debris — a 10 or 15 yard usually covers a seasonal cleanup; see our yard waste dumpster rental service.
When in doubt, call and describe the project
Guessing on size is the single most avoidable mistake in dumpster rental — ordering too small means paying for a second haul, and ordering too large sometimes just wastes usable driveway space for no reason. When you call our Bethlehem yard, tell us the project type, roughly how much material you’re dealing with, and where the container will sit, and our team will recommend a size based on what we actually deliver for jobs like yours across Bethlehem, Allentown, Easton, and the rest of the Lehigh Valley. Visit our full sizing page to compare all five containers side by side, or explore our residential, commercial, and construction dumpster rental services for project-specific guidance.
Weight versus volume: why they’re not the same thing
Volume is only half the sizing question. A 20 yard container looks like it should swallow almost anything, but a load of roofing shingles, brick, or concrete can hit a weight limit long before the box looks full. When we size a project, we’re thinking about both dimensions at once — how much space the debris takes up, and how heavy it actually is. A basement full of old furniture and boxes might genuinely need a 20 yard on volume alone, while a small pile of concrete or masonry debris from a patio tear-out might only need a 10 yard box even though the material is dense and heavy. If your project mixes light household junk with something dense like tile, shingles, or concrete, mention that specifically when you call — it changes the recommendation.
Placement constraints can rule out a size before weight ever does
Sometimes the limiting factor isn’t volume or weight at all — it’s where the container physically fits. Bethlehem’s older neighborhoods, particularly the dense rowhome blocks in South Bethlehem near the former Bethlehem Steel site, often have narrow driveways, shared alleys, or on-street parking that limits what will actually fit. A 40 yard container needs a long, open, unobstructed area to be delivered and picked up safely; that’s rarely realistic on a tight urban lot, even if the project itself is large enough to justify one. In cases like this, we sometimes recommend a smaller container with a faster turnaround — swapping it out once or twice over the course of a project — rather than trying to force a container that won’t physically fit. Newer subdivisions out in Bethlehem Township or Hanover Township, by contrast, tend to have wider driveways and more open placement options, so the largest sizes are usually easier to accommodate there.
Renting across a multi-phase project
Larger renovations and new construction jobs rarely need just one container for the whole project. A common pattern we see: a 20 or 30 yard early on for demolition debris, followed by a swap to a fresh container partway through framing or finish work once the first one fills. If you know your project will run in phases, tell us that up front — we can plan the swap schedule with you instead of you having to call mid-project wondering whether to order a second box or wait for a pickup and redelivery.
Commercial and event sizing works a little differently
Everything above applies mainly to residential and typical contractor projects, but commercial accounts and event cleanups have their own patterns. A retail buildout or office renovation often lands in the same 20 to 30 yard range as a residential remodel, just with a longer rental period attached. Recurring commercial accounts — a property manager clearing multiple units, or a contractor running several jobs at once — sometimes benefit from a standing arrangement rather than booking size fresh each time. And seasonal events like Musikfest generate their own sizing questions entirely, since a vendor cleanup or festival-adjacent property cleanup has a much shorter, more concentrated timeline than a typical renovation; see our Musikfest and event cleanup sizing guide for that specific scenario.
A note on driver experience
Our drivers deliver into Bethlehem's full range of property types every week — wide-open driveways in the newer townships and tight urban lots in the older city blocks alike — and that experience is part of what goes into a sizing recommendation. When our dispatch team asks about your address along with your project type, it's not just paperwork; a lot near Lehigh University or Moravian University, for instance, tends to have different access constraints than a lot out past Coopersburg, and knowing the neighborhood helps us anticipate placement questions before they become a problem on delivery day.
