What Size Dumpster Do I Need? A Complete Guide for Remodels, Roofing, and Cleanouts
Choosing the right dumpster size is one of the most important decisions you’ll make when planning a cleanup, remodel, or construction project.
Too small, and you’ll need extra hauls.
Too large, and you may pay for space you don’t need.
This guide breaks down dumpster sizes in real-world terms so homeowners, contractors, and property managers across the Portland metro area can confidently choose the most efficient and cost-effective option.
Why Dumpster Size Matters More Than You Think
Dumpster size affects:
Total project cost
Weight limits and disposal fees
Placement options
Jobsite safety and efficiency
A properly sized dumpster keeps debris contained, prevents overflow, and reduces downtime—especially on active jobsites.
If you’re planning ongoing debris removal, dumpster rental in the Portland metro area is often the most flexible solution.
Common Dumpster Sizes Explained
Dumpster sizes are measured in cubic yards, which refers to volume—not weight.
Below is a practical breakdown of the most commonly used sizes.
10-Yard Dumpster: Small Projects and Tight Spaces
Best for:
Small garage cleanouts
Bathroom remodels
Yard debris
Light household junk
This size works well when space is limited and debris volume is controlled. It’s also easier to place in tighter driveways.
However, it fills quickly and may not be ideal for bulky materials.
15-Yard Dumpster: Medium Cleanouts and Remodels
Best for:
Basement or attic cleanouts
Flooring removal
Small kitchen remodels
Partial home cleanouts
This size provides a balance between capacity and footprint, making it popular for residential projects that generate steady debris.
20-Yard Dumpster: The Most Popular Choice
Best for:
Full home cleanouts
Roofing projects
Large remodels
Construction debris
For most homeowners and contractors, the 20-yard dumpster offers the best value. It handles significant volume without requiring multiple hauls.
If you’re unsure what size to choose, this is often the safest option.
Larger Dumpsters for Construction and Demolition
Best for:
Commercial construction
Major renovations
Demolition debris
Multi-phase projects
Larger dumpsters reduce the need for frequent pickups and keep busy jobsites running efficiently.
These are commonly used alongside demolition services to manage debris from interior tear-outs and structural removal.
Weight Limits vs Volume: A Common Mistake
Dumpster size determines volume, but weight limits still apply.
Heavy materials include:
Concrete
Dirt and soil
Asphalt
Roofing shingles
Brick and masonry
If your project involves heavy debris, a standard dumpster may exceed weight limits quickly—even if it’s not full.
In these cases, specialty heavy-material dumpsters are the right choice. A professional provider will help match the dumpster to the material, not just the size.
Dumpster Size by Project Type
Home Cleanouts
Most whole-home cleanouts fit best in a 20-yard dumpster, especially if furniture or bulky items are involved.
Roofing Projects
Roofing shingles are heavy. Dumpster size depends on roof square footage and material type, not just volume.
Remodels
Kitchen and bathroom remodels often generate dense debris like tile, drywall, and cabinetry. Size selection should account for both volume and weight.
Construction and Demolition
Active jobsites benefit from larger dumpsters or multiple scheduled hauls to keep work areas clear and compliant.
Dumpster Rental vs Junk Removal for Sizing
If you’re unsure how much debris you’ll have, consider the difference between dumpster rental and junk removal.
With junk removal, the crew handles sizing by volume and labor. This works well for fast, one-day cleanouts.
With dumpster rental, you control the loading timeline, which is ideal for longer projects—but proper sizing is critical.
How to Choose the Right Dumpster Size
To get the most accurate recommendation, be ready to share:
Type of project
Materials being disposed of
Estimated timeline
Placement location
An experienced local provider will help you avoid common mistakes that lead to overage fees or extra hauls.
