What Size Dumpster Do I Need for Your Newnan Project?

The most common question we hear from folks around Newnan and Coweta County is some version of “how big a dumpster do I actually need?” It's a fair question, because guessing wrong in either direction costs you — too small and you're arranging a second pickup, too big and you're paying to haul away mostly empty space. The good news is that most projects fall into a pretty predictable pattern once you know what to look for. Below is a practical breakdown of our five container sizes, plus the one factor people underestimate more than any other: weight.

10-Yard Dumpster: Small Cleanouts and Tight Spaces

A 10-yard dumpster is the right call for small, contained jobs — a single-room cleanout, a garage or shed purge, a small bathroom gut, or clearing out a few years of accumulated clutter. It's also the size that fits most comfortably on a tight driveway or in a narrow side yard, which matters if you're working one of the older in-town lots near the historic downtown courthouse square, where “City of Homes” architecture often comes with a tighter footprint than newer subdivisions. If your project is “a weekend of hauling stuff to the curb” rather than “a full renovation,” start here.

15-Yard Dumpster: The Mid-Size Middle Ground

The 15-yard sits between the 10 and the 20, and it's a good fit for projects that are a notch bigger than a single-room cleanout but don't need a full-scale roll-off — think a garage plus attic combined, a deck removal, a mid-size landscaping cleanup, or a kitchen remodel that's mostly cabinets and flooring rather than structural work. If you're torn between the 10 and the 20, the 15 is worth asking about specifically; it often threads the needle without paying for space you won't fill.

20-Yard Dumpster: The Most Common All-Around Size

The 20-yard dumpster is the workhorse size for a reason — it handles most whole-home cleanouts, larger remodel projects, flooring and carpet tear-outs, and moderate yard debris jobs without needing a second container. It's also a common choice for a roofing tear-off on a small to mid-size roof, though shingle weight deserves its own conversation — more on that below. If you're not sure which size to book and your project feels “medium,” the 20-yard is the safest default to ask about.

30-Yard Dumpster: Larger Renovations and Whole-House Projects

Step up to a 30-yard dumpster when you're tackling a larger home renovation, a whole-house decluttering ahead of a move or an estate cleanout, a multi-room remodel, or a new-construction cleanup where framing offcuts and packaging add up fast. This size is also popular for larger junk removal jobs where volume, not weight, is the limiting factor — bulky furniture, old appliances, and general household volume that just takes up a lot of space without being especially heavy.

40-Yard Dumpster: Major Demolition and Commercial Jobs

The 40-yard dumpster is our largest container, built for major demolition debris work, large-scale construction dumpster rental projects, and commercial jobs generating a high volume of lighter debris — framing lumber, drywall, packaging, and general job-site waste. It's less often the right call for dense material like concrete or dirt, since those loads hit their weight allowance long before they fill the box — which brings us to the part of sizing that trips up more people than the size chart itself.

Why Weight Matters as Much as Volume

Every container size comes with a weight allowance, and it's entirely possible to fill a large dumpster only halfway and still hit that limit, especially with dense debris like concrete, brick, tile, roofing shingles, or dirt. A 20-yard box of shingles can weigh far more than a 20-yard box of household junk, even though they take up the same physical space. This is the single biggest reason a “bigger is safer” approach to sizing can backfire — a bigger container doesn't buy you a bigger weight allowance in proportion, and dense material can push you over the limit regardless of how much room is left in the box. If your project involves concrete, brick, roofing, or other heavy material, our guide to construction debris disposal walks through which materials run heavy and how that should shape your size choice.

When In Doubt, Call and Describe the Project

If you've read through the sizes above and you're still not sure, that's completely normal — and it's exactly what a quick phone call is for. Tell us what you're clearing out, roughly how much of it there is, and whether it leans toward bulky-and-light or dense-and-heavy, and our crew will walk you through sizing on the spot. It's a faster and more accurate path than trying to eyeball cubic yards from a size chart, and it means you get a size — and a flat rate quoted up front — that actually fits your project the first time.
