What Size Dumpster Do I Need?
What size dumpster do I need is the question that decides your whole rental. Pick too small and you pay for a second haul. Pick too big and you pay for empty space. This guide matches every job to the right box.
Quick answer
For most home jobs, a 20 yard box is the right pick. It fits a kitchen remodel or a multi room cleanout. A 10 yard box fits small cleanouts and heavy debris. A 30 yard box fits a whole house cleanout. Use the estimator below to check your job.
Size comparison: all five boxes side by side
Dumpsters are measured in cubic yards. One cubic yard is about the size of a washing machine. A 10 yard box holds about 10 of those units. A 40 yard box holds about 40. The table below shows the real numbers for each size.
| Size | Size (L x W x H) | Pickup loads | Bags (33 gal) | Typical weight |
|---|---|---|---|---|
| 10 yard | 12 to 14 ft x 8 ft x 3.5 to 4 ft | About 3 | 50 to 70 | 1 to 3 tons |
| 15 yard | 16 ft x 8 ft x 4 ft | About 4 to 5 | 80 to 100 | 1.5 to 3 tons |
| 20 yard | 22 ft x 8 ft x 4 to 4.5 ft | About 6 | 110 to 130 | 2 to 4 tons |
| 30 yard | 22 ft x 8 ft x 6 ft | About 9 | 170 to 190 | 3 to 5 tons |
| 40 yard | 22 ft x 8 ft x 7 to 8 ft | About 12 | 230 to 250 | 4 to 6 tons |
Bag counts and pickup loads come from Budget Dumpster sizing guides and Jiffy Junk size charts. Dimensions are typical across haulers. Your exact box may differ by a few inches.
Match your job to the right size
Start with the job, not the box. A small bathroom remodel fits a 10 yard box. So does a single room cleanout. A mid size cleanout or a two room remodel fits a 15 yard box. Flooring jobs often land here too.
A kitchen remodel or a multi room cleanout fits a 20 yard box. This is the most rented size in the country. It suits most home projects. A whole house cleanout needs a 20 or 30 yard box. Furniture fills volume fast. Bulky items eat space even when they weigh little.
Major renovation and large construction jobs need a 30 yard box. Full demolition needs a 40 yard box. Both are for light, bulky debris only. Never load heavy material in a 30 or 40 yard box. The weight limit will break before the box looks full.
Weight matters as much as volume
Volume is only half the choice. Weight is the other half. Concrete, dirt, brick, and tile are heavy. A 10 yard box is the right pick for them. It is low and wide. It keeps the load under the truck limit.
Shingles are heavy too. One square of shingles weighs about 200 to 350 pounds. A 2,000 square foot roof can produce 3,000 to 7,000 pounds of shingles. That is why a roof tear-off often needs a smaller box than the volume suggests.
Our weight limits guide has a table of weight by material. Read it before you book a box for heavy debris. It can save you hundreds in overage fees.
Measure your space before you book
Delivery needs room. The truck needs about 10.5 feet of width and 60 feet of straight clearance. It also needs 25 to 30 feet of vertical clearance. Low wires and tree limbs can block a drop-off.
Walk your driveway before booking day. Move cars and bins. Note the slope. A steep slope can shift a loaded box. A soft spot in the drive can sink under the weight. Pick a flat, firm spot near the work area. The closer the box sits to the job, the less you carry.
If your drive is tight, tell the hauler. A 10 or 15 yard box fits where a 30 yard box cannot. Some homes need the box on the street instead. That needs a permit in most Colorado cities. Our permit guide covers the street rules city by city.
Common sizing mistakes to avoid
The top mistake is picking too small a box. It feels like a saving. It is not. An overfilled box cannot be picked up. You pay for a second haul or a swap. The second trip often costs more than the size upgrade would have.
The second mistake is picking a big box for heavy debris. A 30 yard box full of concrete can weigh over 10 tons. No truck can haul it legally. The driver will refuse the load. You will pay to unload it and reload a smaller box.
The third mistake is guessing the volume of furniture. A sofa looks small in a room. It fills a big share of a 10 yard box. Count your large items first. Then pick the size. When in doubt, use the estimator above and size up.
What size dumpster do I need for a remodel?
A remodel is the job where size choice matters most. A small bathroom remodel fits a 10 yard box. The tub, tile, and vanity are heavy but small in volume. A mid size bathroom may need a 15 yard box.
A kitchen remodel needs a 20 yard box in most cases. Cabinets, counters, flooring, and drywall fill volume fast. A large kitchen with an island and a wall removal may need a 30 yard box. A whole home renovation needs a 30 yard box. Demolition of a full structure needs a 40 yard box.
Watch the debris type as you pick. Tile and plaster are heavy. A kitchen with a tile floor may hit the weight limit in a 20 yard box. A kitchen with vinyl flooring will not. Tell your hauler the debris type when you book.
What if your job does not fit one box?
Some jobs need two boxes. A whole house cleanout plus a roof tear-off is two loads. A demolition plus a yard cleanup is two loads. Two small boxes can beat one big box when the debris types differ.
A swap is the other answer. The hauler takes the full box and drops a fresh one. Swaps fit jobs that fill a box before the work ends. Ask the swap price when you book. It is often close to a new rental.
Do not force one box to hold two jobs. An overfilled box cannot be picked up. A second box costs less than an overfill fee plus a failed pickup. Our overfill guide shows the fill line rule.
Frequently asked questions
Is it better to size up or size down?
Size up when you are between two sizes. The price gap between sizes is small. A second haul costs far more than the bigger box. Most homeowners underestimate by one size.
What size dumpster for a garage cleanout?
A 10 yard box fits most single garage cleanouts. It holds about 3 pickup loads or 50 to 70 bags. A two car garage packed floor to ceiling may need a 15 yard box.
What size dumpster for a kitchen remodel?
A 20 yard box fits most kitchen remodels. Cabinets, counters, and flooring fill volume fast. A small kitchen with light debris may fit in a 15 yard box.
What size dumpster for a roof tear-off?
A 10 yard box fits a one layer tear-off up to about 2,000 square feet. A two layer tear-off needs a 20 yard box. Shingles are heavy, so weight decides before volume does.
Can a dumpster be too big for my driveway?
Yes. A 30 or 40 yard box is about 22 feet long and needs 60 feet of straight clearance for the truck. Measure your driveway first. A tight drive may only fit a 10 or 15 yard box.
