How to Choose the Right Dumpster Size for Your Project
Match the dumpster size to your project type. A 10 yard fits single-room remodels and small roofing jobs. A 20 yard is the most popular size — right for mid-sized renovations, mid-sized roofs, and garage cleanouts. A 30 yard handles whole-house cleanouts, major construction, and additions. When in doubt, size up — it's cheaper than a second rental.
Quick Decision Tree
Answer these three questions to land on the right size:
- What kind of debris? Dense (concrete, dirt, shingles) → 10 yard. Mixed construction → 20 yard. Bulky household → 20 or 30 yard.
- How many rooms / how big a project? One room → 10 yard. 2–4 rooms → 20 yard. Whole house → 30 yard.
- Do you have room for the bigger one? A 30 yard needs ~22 ft of length plus truck clearance. Tight driveway → step down to a 20 yard.
Side-by-Side Size Comparison
| Size | Dimensions | Weight Included | Flat Rate | Best For |
|---|---|---|---|---|
| 10 Yard | 12' L × 8' W × 3.5' H | 1 ton included | $399 | Single-room remodel, small roof (under 15 squares), garage cleanout, concrete or dirt |
| 20 Yard | 16' L × 8' W × 6' H | 3 tons included | $597 | Average roof tear-off, mid-sized renovation, deck removal, flooring throughout home |
| 30 Yard | 22' L × 8' W × 6' H | 3 tons included | $597 | Whole-house cleanout, estate cleanout, additions, large construction projects |
By Project Type
| Project | Recommended Size | Why |
|---|---|---|
| Kitchen remodel | 10 or 20 yard | 10 yd if cabinets only; 20 yd if flooring + drywall too |
| Full roof replacement (~2,000 sq ft) | 20 yard | Average asphalt tear-off is ~25 squares (~5 tons) |
| Whole-house cleanout / estate | 30 yard | Furniture and household goods are bulky but light |
| Garage cleanout | 10 yard | Most garages produce 8–10 yards of debris |
| Deck or fence tear-off | 20 yard | Lumber stacks loosely and takes more space than expected |
| Small bathroom reno | 10 yard | Tile, vanity, tub fit comfortably with weight to spare |
| Flooring removal throughout house | 20 yard | Old hardwood, tile, and carpet add up fast |
| Concrete patio / driveway tear-out | 10 yard | Hits the weight limit before half full — never size up |
| New construction framing scrap | 30 yard | Lumber and OSB are voluminous but not heavy |
| Storm debris (branches, fencing) | 20 or 30 yard | Branches stack inefficiently — size up |
When NOT to Size Up
"When in doubt, size up" works for bulky debris — furniture, drywall, lumber. It's the wrong move for dense materials. Every dumpster has a weight limit. Concrete, dirt, asphalt, brick, and roofing shingles will hit that weight limit long before they fill the box visually. A 10 yard full of concrete already weighs more than a 30 yard full of a household cleanout. For dense debris, the 10 yard is almost always the right answer — you'll just have a half-full looking dumpster on the truck. The EPA's data on sustainable management of construction and demolition materials shows just how much of that tonnage is concrete and asphalt.

Cost Implications of Sizing
On the Eastern Shore, the 20 yard and 30 yard are the same flat rate ($597) — so for bulky debris, the 30 yard is almost always the smart choice if access permits. Stepping from a 10 yard ($399) to a 20 yard ($597) is a $198 jump, which is much cheaper than a second 10 yard delivery ($399).
