Few things stall a weekend project faster than a dumpster that's too small to finish the job — or too big and sitting half-empty in your driveway. If you're tackling a cleanout, remodel, or roofing job around Newfield, Sanford, or out toward the Sebago Lakes Region, picking the right roll-off size up front saves you money and a second delivery. At Harvey's Heavy Hauling, we deliver fully insured roll-off dumpsters across Western and Southern Maine and Seacoast New Hampshire, and the most common question we hear is simple: what size do I actually need? Here's how to figure it out.

How Dumpster Sizes Work

Roll-off dumpsters are measured in cubic yards — that's the volume of debris they hold, not their footprint on your driveway. To picture it, one cubic yard is roughly the size of a standard washing machine, and a full-size pickup truck bed holds about 2.5 to 3 cubic yards. So a 10-yard container equals about three full truckloads of debris hauled away in one trip.

The four sizes most homeowners and contractors reach for are the 10, 15, 20, and 30-yard. Each has a sweet spot.

10-Yard Dumpster: Small, Focused Projects

The 10-yard is the smallest roll-off and the easiest to load — it sits low to the ground, so you can toss debris over the side without a ramp. It holds roughly three pickup-truck loads.

Single-room cleanouts or a small garage purge
Bathroom remodels and small flooring tear-outs
Modest yard cleanups and brush removal
Heavy debris like shingles, dirt, or concrete (where weight maxes out fast)

If your project is heavy but low-volume — say, a small roof or a patch of broken concrete — the 10-yard is often the smart pick because you'll hit the weight limit long before you fill the space.

15-Yard Dumpster: The Homeowner Favorite

The 15-yard is one of the most popular residential sizes because it adds real capacity while still fitting comfortably in a typical Maine driveway. Figure on four to five truckloads of room.

Large garage, attic, or basement cleanouts
Kitchen remodels and deck tear-offs
Mid-size roofing jobs
Estate and downsizing cleanouts

If you're between two sizes and your debris is mostly household material and light construction waste, the 15-yard usually hits the balance of capacity and cost.

20-Yard Dumpster: The Workhorse

The 20-yard is the most commonly rented size in the country, and for good reason — it handles the widest range of projects. It holds roughly six to eight pickup loads.

Whole-home or estate cleanouts
Major renovations spanning multiple rooms
Large landscaping overhauls and storm cleanup
Mid-to-large roofing and siding jobs

One caution: heavy materials like concrete, brick, and wet soil will reach the weight limit well before the box looks full. For those loads, the extra capacity you actually need is weight allowance, not floor space — so talk to us before you assume bigger is better.

30-Yard Dumpster: Big Jobs and Contractors

When you're gutting a house, clearing a multi-building property, or running a new construction site, the 30-yard gives you the volume to keep work moving without constant swaps. It's the go-to for contractors around Saco, Greater Portland, and Rochester/Dover NH who need to stage a large job efficiently.

What Can't Go in a Roll-Off Dumpster

Maine and New Hampshire have rules about what's allowed in a roll-off, and a banned item can mean extra fees or a refused load. Generally keep these out:

Hazardous materials — paint, solvents, oil, propane tanks, and chemicals
Tires, batteries, and large appliances with refrigerants
Electronics in many cases (check first)
Wet paint and certain liquids

When in doubt, ask. We'll tell you exactly what your local transfer station accepts and help you plan around the restricted items so there are no surprises on pickup day.

Picking the Right Size for Your Maine Project

A good rule of thumb: estimate your debris in pickup-truck loads, then round up one size. People underestimate volume far more often than they overestimate it, and a single right-sized container almost always beats paying for a second haul. Spring and early-summer cleanups across Shapleigh, Limerick, Cornish, and Waterboro tend to run heavier than expected once the brush, old decking, and garage clutter start piling up.

Not sure where you land? That's exactly what a quick phone call solves. Tell us about your project and we'll recommend a size — no upselling, just the right container for the job.

More Than Just Dumpsters

Many projects need more than a place to put debris. If your cleanup is also a refresh, we deliver bulk materials like screened loam, gravel, crushed stone, mulch, and compost to finish the job. Hauling a tractor, skid steer, or shed across the region? Our heavy equipment transport has you covered. And for the repairs that surface mid-cleanout — a wobbly deck rail or a fence section that finally gave out — our handyman services can knock them out while you've got momentum.
