What size dumpster do I need?
Pick too small and you pay for a second haul; too big and you pay for air. Here’s how to match your job to the right roll-off.
Roll-off dumpsters are measured in cubic yards — how much they hold, not how heavy. MCI Waste runs 10, 15, 20, 30 and 40 yard containers across Westchester, Putnam and Dutchess. Most homeowners land on a 20.
Quick size guide
| Size | Best for | Holds about |
|---|---|---|
| 10 yard | Single room, small yard, small cleanout | 3–4 pickup loads |
| 15 yard | Garage or basement, small renovation | 5–6 pickup loads |
| 20 yard | Kitchen/bath remodel, whole-home cleanout | 7–8 pickup loads |
| 30 yard | Roofing tear-off, large renovation | 9–12 pickup loads |
| 40 yard | Construction & demolition, commercial | 12–16 pickup loads |
How to choose
Think about the heaviest, bulkiest day of your project, not the average. If you’re between two sizes, size up — one container that fits everything beats paying for a swap-out.
- Decluttering a room or yard? A 10–15 yard is plenty.
- Remodeling a kitchen or bath? A 20 yard is the sweet spot.
- Re-roofing or gutting a space? Step up to a 30.
- Running a construction or demo job? A 40 yard keeps the site clear.
