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 | $395 | Single-room remodel, small roof (under 15 squares), garage cleanout, concrete or dirt |
| 20 Yard | 16' L × 8' W × 6' H | 3 tons included | $570 | Average roof tear-off, mid-sized renovation, deck removal, flooring throughout home |
| 30 Yard | 22' L × 8' W × 6' H | 3 tons included | $570 | 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.

Cost Implications of Sizing
On the Eastern Shore, the 20 yard and 30 yard are the same flat rate ($570) — so for bulky debris, the 30 yard is almost always the smart choice if access permits. Stepping from a 10 yard ($395) to a 20 yard ($570) is a $175 jump, which is much cheaper than a second 10 yard delivery ($395).
