Picking the wrong dumpster trailer size is the most common — and most expensive — mistake in rental. Order too small and you'll pay for a second trailer or overflow fees; order too large and you're paying for air. Our dumpster size calculator uses your project type and a rough debris estimate to recommend the right 14, 16, or 20 yard trailer.
How the calculator works
- Select your project type (cleanout, remodel, roofing, construction, landscaping).
- Estimate the volume of debris in pickup-truck loads or cubic yards.
- We factor in weight for dense materials like concrete, dirt, and shingles.

Why weight matters as much as volume
Concrete, dirt, and asphalt shingles are dense. A 14 yard trailer can hold ~14 cubic yards of light debris but may hit its weight limit with only 4–5 yards of concrete. For heavy materials, we always size down and run a dedicated heavy-debris load.
