What Size Dumpster Do I Need in Manchester, NH?

Every week our dispatch phone rings with some version of the same question: “What size dumpster do I actually need?” It's the right question to ask before you book, because guessing wrong in either direction costs you money — too small and you're paying for a second haul, too large and you're paying for empty space you never filled. Here's how we walk Manchester homeowners and contractors through it, size by size.

Start with the project, not the container

The container is the easy part. The harder part is being honest about what's actually coming out of the house, garage, yard, or job site. A single-room flooring tear-out generates a very different volume than a whole-house cleanout, and roofing debris is deceptively heavy for its size — shingles pack dense. At Granite Dumpster Rental we'd rather talk you into the right size on the phone than let you order the wrong one and call us back frustrated.

10-yard dumpster — small jobs, tight driveways

The 10-yard is our smallest roll-off, measuring 14' × 7.5' × 3.5'. It holds roughly 50–70 contractor bags, or about 3 pickup-truck loads, and carries a 1–2 ton allowance. This is the size for a single bathroom gut, a garage clean-out, a small deck tear-off, or clearing out a shed. It's also the only size we quote a published price range on — average cost runs $350–$550 depending on your specific job and debris type. If your driveway is tight or you just need something out of the way fast, start here. Full details are on our 10-yard dumpster page.

15-yard dumpster — the mid-size workhorse

Step up to a 15-yard (16' × 7.5' × 4.5') and you're looking at 80–100 bags, 4–5 truck loads, and a 2–3 ton allowance. This is the size we recommend most for kitchen and bath remodels, flooring replacement across multiple rooms, roofing tear-offs on smaller homes, and general yard work cleanup. It's a good middle ground — enough room to not think twice about what you're throwing in, without paying for capacity you won't use. See the specs on our 15-yard dumpster page.

20-yard dumpster — our most popular size, and probably yours

The 20-yard (22' × 7.5' × 4.5') is what most Manchester-area customers end up renting, and for good reason — it hits the sweet spot for whole-house cleanouts, larger remodels, roofing jobs up to about 50 squares, and bigger landscaping projects. It holds 110–130 bags or about 6 truck loads, with a 3–4 ton allowance. When someone calls unsure of what to order and describes a project that's more than a single room but not a full construction site, this is usually where we land. Check the 20-yard dumpster page for the full breakdown.

30-yard dumpster — whole-house and commercial jobs

At 22' × 7.5' × 6', the 30-yard holds 170–190 bags, roughly 9 truck loads, with a 4–5 ton allowance. This is the size for whole-house projects generating serious volume, commercial cleanouts, and new-build construction sites where framing scrap and packaging waste pile up fast. It needs more room to place than the smaller sizes, so make sure you've got the clearance before you book — more on that below.

40-yard dumpster — major demolition and large sites

Our largest container, the 40-yard (22' × 7.5' × 8'), holds 230–250 bags, about 12 truck loads, and a 5–6 ton allowance. This is reserved for major demolition, large construction sites, and commercial fit-outs where volume is the whole point. If you're not sure whether you need a 30 or a 40, call us — we'd rather ask two or three questions about your job than have you order the wrong one.

Don't forget site requirements

Whatever size you land on, our trucks need about 60 feet of clear space to back in and roughly 25 feet of overhead clearance, plus a flat, hard surface like a driveway or paved lot to set the container on. If your site is tight, tell us when you book so we can plan placement — this matters more on a 30 or 40-yard than it does on a 10.

When in doubt, call before you book

Sizing a dumpster over the phone takes us two or three minutes because we're not reading from a script — we're actually asking about your project. That's the advantage of being a local Manchester dumpster rental team and not a call center: whoever answers the phone has probably delivered a container to your street before. If you want the full lineup side by side, our sizes page covers all five, and our services page breaks things down by project type instead of size if that's an easier way for you to think about it.

A quick note on rental period

Every size comes with our standard 3–7 day rental window, which covers the vast majority of residential and small commercial jobs. If your project is going to run longer, mention it when you call — we'd rather set expectations up front than surprise you later.

Matching size to common Manchester-area project types

A lot of the confusion around sizing comes from thinking in terms of “small, medium, large” instead of the actual project. Here's how the sizes map to jobs we see regularly around Manchester, Bedford, Derry, and the rest of our service area:

• Single-room renovation or garage clean-out: 10-yard.
• Kitchen or bath remodel, flooring replacement, small roofing tear-off: 15-yard.
• Whole-house cleanout, larger remodel, roofing up to about 50 squares: 20-yard.
• Whole-house project, commercial cleanout, new-build construction: 30-yard.
• Major demolition, large construction site, commercial fit-out: 40-yard.

These are starting points, not hard rules — a heavily cluttered garage can push you from a 10 to a 15, and a roofing job on a larger home can push a 20 to a 30. What matters most is describing the actual project when you call rather than trying to guess a category it fits into.

Residential vs. commercial sizing tends to differ

Most homeowners land in the 10 to 20-yard range, since residential projects — even substantial renovations — rarely generate the volume of a commercial teardown or a new-construction site. Contractors and property managers more often need a 20-yard and up, sometimes with multiple pulls scheduled across a longer project. If you're planning a job that spans both categories, like a gut renovation ahead of a resale, it's worth talking through the full scope on the phone rather than sizing for just the first phase.
