How to Choose the Right Dumpster Size: A No-BS Guide for 2025
Quick Answer: Most homeowners need a 20-yard dumpster. It handles 85% of residential projects (kitchen remodels, garage cleanouts, small deck removals). For full home renovations or large roofing jobs, go with a 30-yard. Construction pros typically need 40-yard containers.

Why Dumpster Size Actually Matters
Look, choosing a dumpster size isn’t rocket science. But get it wrong? You’ll either pay for a second dumpster (adding $300-$500 to your bill) or rent something way too big and waste money on empty space.
Here’s what nobody tells you: rental companies make serious profit when you get the size wrong. Order too small, they charge you overage fees or deliver a second container. Order too large, they pocket the difference. That’s why most company websites are deliberately vague about sizing.
I’ve seen people rent 40-yarders for basic garage cleanouts. Total waste of $150-$200. I’ve also watched homeowners cram debris around their yard when their 10-yard filled up halfway through a deck removal. Don’t be either of these people.
Insider Tip: Rental periods are usually 7-14 days regardless of size. So the “rent small, get a second one later” strategy actually doubles your cost AND the hassle. Size up if you’re uncertain.
The 4 Standard Dumpster Sizes Explained
Dumpster sizes are measured in cubic yards—how much space they hold, not their physical dimensions. This confuses everyone at first because a “20-yard dumpster” doesn’t mean 20 yards long.
10-Yard Dumpster
-
- Holds: About 4 pickup truck loads
- Dimensions: Roughly 14′ long × 7.5′ wide × 3.5′ tall
- Weight limit: 2-3 tons (4,000-6,000 lbs)
- Costs: $250-$450 for a week
Think of this as the “apartment cleaner.” Great for small projects where you don’t have much square footage to work with. The low sides make it easy to toss stuff in without a ramp.
Best for:
-
- Single room cleanouts
- Small bathroom remodels (just the demo, not full gut jobs)
- Yard waste from small properties
- Minor deck repairs (not full removals)
Real talk: Most homeowners skip this size. It fills faster than you think, and the price difference between a 10-yard and 20-yard is usually only $50-$75. Not worth the risk.
20-Yard Dumpster
-
- Holds: About 8 pickup truck loads
- Dimensions: Roughly 22′ long × 7.5′ wide × 4.5′ tall
- Weight limit: 3-4 tons (6,000-8,000 lbs)
- Costs: $325-$575 for a week
This is your Goldilocks size. Not too big, not too small. If you’re reading this guide because you don’t know what to get, get a 20-yarder. Seriously.
Best for:
-
- Kitchen or bathroom renovations
- Garage cleanouts with years of accumulated junk
- Medium deck removals (up to 300 sq ft)
- Flooring removal from 1,500-2,000 sq ft
- Carpet and padding removal
- Estate cleanouts for 2-3 bedroom homes
The 20-yard handles what I call “enthusiastic homeowner projects”—stuff you can realistically demo yourself over a weekend or two without a full crew.
Insider Tip: If you’re doing a kitchen reno and keeping your cabinets, a 20-yard works. Ripping out cabinets too? Consider a 30-yard. Cabinets eat up space like you wouldn’t believe.
30-Yard Dumpster
-
- Holds: About 12 pickup truck loads
- Dimensions: Roughly 22′ long × 7.5′ wide × 6′ tall
- Weight limit: 4-5 tons (8,000-10,000 lbs)
- Costs: $375-$650 for a week
Now we’re talking serious renovation territory. The 30-yard is for projects that generate a LOT of bulky debris or when you’re gutting multiple rooms.
Best for:
-
- Whole-home renovations (gutting 2-3 rooms)
- New construction cleanup
- Large deck removals (300-600 sq ft)
- Full roof replacements (up to 3,000 sq ft)
- Major landscaping overhauls
- Commercial cleanouts
One thing that surprises people: the 30-yard isn’t much more expensive than the 20-yard. Usually $50-$100 difference. So if you’re on the fence, the 30-yard gives you breathing room.
Watch out: These are tall. The sides are 6 feet high, which means you’ll need to lift debris higher or use the walk-in door. Not ideal if you’re throwing in a lot of heavy material by hand.
40-Yard Dumpster
-
- Holds: About 16 pickup truck loads
- Dimensions: Roughly 22′ long × 7.5′ wide × 8′ tall
- Weight limit: 5-8 tons (10,000-16,000 lbs)
- Costs: $450-$800 for a week
The beast. This is overkill for most residential projects unless you’re doing a complete home gut or major commercial work.
Best for:
-
- Complete home demolitions
- Large commercial construction sites
- Major roof replacements (3,000+ sq ft, or heavy materials like slate/tile)
- Window/siding replacement for large buildings
- Industrial cleanouts
Real talk: The 40-yard is more common on construction sites than residential driveways. And here’s the thing—it’s TALL. Eight feet tall means you’re not casually tossing stuff in. You need a plan (or a crew) to load it efficiently.
Size Comparison Table
| Size | Holds | Best Projects | Avg Cost | Length | Height |
|——|——-|—————|———-|———|———|
| 10-Yard | 4 truck loads | Small cleanouts, minor demos | $250-$450 | 14 ft | 3.5 ft |
| 20-Yard | 8 truck loads | Kitchen remodels, garage cleanouts | $325-$575 | 22 ft | 4.5 ft |
| 30-Yard | 12 truck loads | Whole-home renovations, roofing | $375-$650 | 22 ft | 6 ft |
| 40-Yard | 16 truck loads | Commercial projects, full demos | $450-$800 | 22 ft | 8 ft |
Prices vary by location, rental period, and disposal fees. These are national averages.
How to Calculate What Size You Need
Forget the complicated cubic yard calculators. Here’s how to actually figure this out:
Method 1: The Pickup Truck Rule
How many pickup truck loads would your debris fill? Multiply that by 1.5 (because you’ll pack a truck tighter than a dumpster).
Method 2: Square Footage Trick
For flooring/carpet removal: Divide your square footage by 100. That’s roughly the dumpster size you need.
-
- 1,000 sq ft of carpet ≈ 10-yard
- 2,000 sq ft of hardwood ≈ 20-yard
For roofing: Divide roof square footage by 100, then add 10%.
-
- 2,000 sq ft roof ≈ 20-yard (22 yards to be safe)
- 3,000 sq ft roof ≈ 30-yard
Method 3: Room Count Method
Cleanouts/renovations:
-
- 1-2 rooms = 10-yard
- 2-4 rooms = 20-yard
- 4-6 rooms = 30-yard
- Whole house = 40-yard
This assumes you’re generating typical demolition debris, not just grabbing a few things.
Insider Tip: Call the rental company and describe your project in detail. Good companies have seen thousands of jobs and can dial in the size better than any calculator. But know the basics first so you can smell BS if they’re upselling you.
Common Projects and Their Sizes
Kitchen Remodel
-
- Keeping cabinets, replacing counters/appliances: 10-yard (but 20-yard is safer)
- Full gut including cabinets: 20-yard
- Kitchen + demo of adjacent wall/dining area: 30-yard
Cabinets are deceptive. They’re bulky and awkward. A full set of kitchen cabinets alone can eat up half a 20-yard dumpster.
Bathroom Renovation
-
- Cosmetic (vanity, toilet, fixtures): 10-yard
- Full gut (tile, tub, everything): 15-20-yard
- Multiple bathrooms: 20-30-yard
Tile and concrete backerboard add weight fast. If you’re demoing a lot of tile, watch your weight limits.
Roofing Projects
-
- 1,000-1,500 sq ft roof: 20-yard
- 1,500-3,000 sq ft roof: 30-yard
- 3,000+ sq ft or multi-layer removal: 40-yard
Asphalt shingles are HEAVY. A roofing project that looks like it might fit in a 20-yard often maxes out the weight limit. Size up here.
Deck Removal
-
- Small deck (under 200 sq ft): 10-yard
- Medium deck (200-400 sq ft): 20-yard
- Large deck (400-600 sq ft): 30-yard
Breaking down the deck into smaller pieces saves space. Tossing full boards in wastes probably 30% of your capacity.
Estate Cleanout
-
- 1-2 bedroom home: 20-yard
- 3-4 bedroom home: 30-yard
- Full house + garage + shed: 40-yard
Estate cleanouts vary wildly. Hoarder situations? Add a size. Mostly empty house? You might get away with one size smaller.
Garage Cleanout
-
- 1-car garage, moderately full: 10-yard
- 2-car garage, packed over the years: 20-yard
- Garage + attic + basement purge: 30-yard
People underestimate garage cleanouts. Years of accumulated stuff compresses into dense, space-eating piles.
3 Mistakes That’ll Cost You Money
Mistake 1: Ordering Too Small “To Save Money”
The price difference between a 10-yard and 20-yard is usually $75-$100. Know what a second dumpster costs? The full price again, plus another delivery fee ($75-$150). Plus the hassle of scheduling, waiting, coordinating.
Do this instead: If you’re between two sizes, go bigger. The peace of mind is worth $75.
Mistake 2: Not Accounting for Demo Expansion
Here’s something wild: demolished materials take up 3-4x more space than when they were installed. A neat stack of drywall becomes a mountain of broken chunks. A tidy deck becomes a pile of splintered boards.
Do this instead: Visualize your debris pile, then mentally double it. That’s closer to reality.
Mistake 3: Ignoring Weight Limits
Size isn’t just about volume. A 20-yard dumpster holds 20 cubic yards of space, but typically only 3-4 tons of weight. Fill it with concrete or dirt? You’ll hit the weight limit with 30% of the space used.
Heavy materials (concrete, asphalt, dirt, brick) need special attention. Check out our weight limits guide for details.
Do this instead: For heavy materials, order based on weight capacity, not volume. Or rent a separate dumpster just for heavy stuff.
When to Size Up vs. Size Down
Size UP if:
-
- You’re demolishing anything (demo creates more volume than you think)
- Your project might expand (“while we’re at it” syndrome is real)
- You’re renting during peak season (summer) and don’t want to wait for a second delivery
- You have heavy materials mixed with light materials
- Multiple people are working and generating debris quickly
- Your property has space for a larger dumpster
Size DOWN if:
- You have strict space limitations (narrow driveway, HOA restrictions)
- You’re CERTAIN about the scope and it’s a small, contained project
- You’re disposing of light, compactible materials
- You’re willing to load efficiently and break down materials
- Budget is extremely tight and you’d rather make two trips if needed
Insider Tip: “I’ll just compact everything” is famous last words. Sure, you can break down boxes and smash drywall. But you’re not going to compact 2x4s, cabinets, or a bathtub. Be realistic about what can actually be compressed.
Pro Tips for Getting the Size Right
Tip 1: Take Photos and Measurements
Before calling for a quote, take photos of what you’re tossing and measure the area you’re demoing. Rental companies can give better advice with visuals.
Tip 2: Check Your Space First
A 20-yard dumpster is 22 feet long. Measure your driveway. Account for the delivery truck needing space to maneuver. Don’t learn this lesson the hard way when the driver can’t fit it where you wanted.
Tip 3: Ask About Exchange Programs
Some companies let you exchange a full smaller dumpster for a fresh one at a reduced rate. If you’re really unsure, start with a 20-yard and ask about exchange options upfront.
Tip 4: Consider Rental Period
Standard rentals are 7-14 days. If you’re working solo on weekends only, you might generate less debris than a full crew working daily. But don’t rent a smaller size just because you’re working slowly—debris doesn’t shrink.
Tip 5: Call During Your Demo
Seriously. If you’re mid-project and realize you misjudged, call immediately. It’s easier to add a second dumpster while you still have debris to load than to figure it out after you’ve already piled stuff around your yard.
What About Bag Dumpsters?
You’ll see companies offering “dumpster bags”—basically giant waste bags you fill and they pick up. They hold about 3 cubic yards (roughly 1 pickup truck load).
When they work: Tiny projects, limited driveway space, or when you’re not sure when you’ll finish.
When they don’t: Any project bigger than a bathroom vanity swap. They’re expensive per cubic yard ($100-$200 for 3 yards vs. $250-$450 for 10 yards). And they’re a pain to fill because they collapse as you load them.
Get a Free Quote
Stop guessing. Get a free quote and talk to someone who’s seen your exact project type a hundred times. Describe your project in detail, mention any heavy materials, and ask for their honest recommendation.
Most good rental companies would rather get you the right size the first time than deal with angry callbacks and second deliveries. Use that to your advantage.
FAQ
What’s the most common dumpster size for homeowners?
The 20-yard is hands-down the most popular residential size. It handles probably 70-80% of typical home projects—kitchen remodels, garage cleanouts, medium renovations, and small roofing jobs. It’s the sweet spot between capacity and cost.
Can I change dumpster sizes after ordering?
Usually yes, but call ASAP. Most companies will let you adjust your order before delivery at no charge. After delivery, some offer exchanges (for a fee), but it’s way easier to get it right upfront. The earlier you call, the more flexible they can be.
How much does size affect price?
Less than you’d think. The jump from 10-yard to 20-yard is typically $75-$125. From 20-yard to 30-yard, another $50-$100. The biggest cost factors are actually your location, disposal fees, and rental period—not size. This is why “going small to save money” often backfires.
What if my dumpster is too small?
You have three options: (1) Rent a second dumpster at full price, (2) Haul the overflow yourself to a dump (time-consuming and often costs more than you’d save), or (3) Some companies offer “overage fees” if you go slightly over, usually $50-$100 per ton. None are ideal, which is why sizing correctly matters.
Do I need to fill the dumpster completely?
Nope. You pay for the size you rent, whether you fill it 50% or 100%. That said, don’t rent a 40-yard for a tiny bathroom remodel. But between a 20-yard and 30-yard? If you fill the 20-yard to 80%, you’re still fine. No refunds for empty space though.
