What Size Dumpster Do You Need? A Real Sizing Guide for the Valley

Tue, 11 Aug 2026 21:46:11 GMT

Renting a dumpster sounds simple, until you're staring at a list of sizes with no idea what any of them actually mean for your project. Order too small, and you're paying for a second haul. Order too big, and you're paying for space you never use. For Phoenix homeowners tackling anything from a small cleanout to a full renovation, getting the size right the first time saves both money and headaches.

At Capital Waste Services , we carry six roll-off sizes, 10, 12, 20, 25, 30, and 40-yard, so there's a fit for almost any project, from a small garage cleanout to industrial-scale construction. Here's how they break down.

10 Yard (16' Long, 8' Wide, 3.5' Tall)

Great for concrete, dirt, small cleanouts, and light renovation. If you're clearing a garage, doing a small landscaping project, or handling a single-room decluttering job, this is usually your starting point.

12 Yard (18' Long, 8' Wide, 3' Tall)

Great for larger loads of concrete, dirt, small cleanouts, and light renovation. This size gives you a bit more length and capacity than the 10-yard while staying low profile, useful when you've got a slightly bigger version of the same kind of project.

20 Yard (18' Long, 8' Wide, 5' Tall)

Ideal for larger cleanouts, medium-scale construction projects, yard debris, and heavy materials. This is a common choice for kitchen or bathroom remodels, roofing tear-offs, and flooring replacement jobs where you need real capacity without going oversized.

25 Yard (20' Long, 8' Wide, 5' Tall)

A great option for large cleanouts, medium-scale demolition, commercial projects, and green waste cleanup. If your project sits between a standard remodel and a full renovation, this size adds meaningful capacity over the 20-yard.

30 Yard (22' Long, 8' Wide, 6' Tall)

Perfect for major renovations, estate cleanouts, and large construction jobs. When you're dealing with a whole-home renovation, a full property cleanout, or a sizable construction project, this is where most homeowners and contractors land.

40 Yard (23' Long, 8' Wide, 8' Tall)

Our largest option, ideal for industrial construction, commercial projects, major renovations, and multi-unit cleanouts. This size is built for big jobs: new construction, large commercial projects, or cleanouts spanning multiple units.

A Quick Way to Think About It

If you can picture your debris filling a pickup truck bed a few times over, start with a 10 or 12-yard. If you're mid-renovation with several rooms of debris or a roofing job, a 20 or 25-yard usually fits. If you're tackling a full home renovation, estate cleanout, or new construction, plan on a 30 or 40-yard.

Not Sure Which Size Fits Your Project?

That's exactly what our team is here for. When you call Capital Waste Services , we'll ask a few quick questions about your project, room count, material type, and timeline, and recommend the right size before you ever see a delivery truck. And if you fill your dumpster before your project is done, we offer swap-out service, so you're never stuck waiting on the wrong size.
