What Size Dumpster Do I Need?

When embarking on a new project, whether it’s a home renovation, a major cleanout, or a construction job, one of the key questions you’ll face is: “How big of a dumpster do I need?” It’s a crucial decision, as the right dumpster size will ensure that your waste management is efficient, cost-effective, and compliant with local regulations.

Here, we’ve broken down every step to choosing the right dumpster for whatever projects life throws your way.


Understanding Dumpster Sizes

Getting the right size dumpster — measured in cubic yards or cubic feet — can make or break your project. If it’s too big, you’re spending extra money and effort. But if it’s too small and you have to take multiple truckloads to empty it, you’re using up more time and money. Here are some tips to find out what size dumpster you need.

10 Yard Dumpster

  • Dimensions: Typically 12 ft. long by 8 ft. wide by 3.5 ft. high
  • Best for: Small basement, attic, or garage cleanouts; 250 sq. ft deck removal; 1500 sq. ft. of roof shingles.

15 Yard Dumpster

  • Dimensions: 16 ft. long by 8. ft wide by 4 ft. high
  • Best for: medium-sized projects like minor landscaping or home renovations.

20 Yard Dumpster

  • Dimensions: Generally 22 ft. long by 8 ft. wide by 4 ft. high
  • Best for: Large basement, attic, or garage cleanouts; 300-400 sq. ft deck removal; 2500-3000 sq. ft. of roof shingles.

30 Yard Dumpster

  • Dimensions: Usually 22 ft. long by 8 ft. wide by 6 ft. high
  • Best for: Major home additions, new home construction, garage demolition.

40 Yard Dumpster

  • Dimensions: Commonly 22 ft. long by 8 ft. wide by 8 ft. high
  • Best for: Large-scale demolition, significant home construction projects, commercial roof tear-off.

When determining the dumpster size you need, consider both the scale of your project and the type of heavy debris you’ll be disposing of. Each size has its own weight limits and cubic yardage that determine its suitability for different jobs.


Determining the Right Size for Your Project

Selecting the most appropriate dumpster size is crucial to the success of your project, ensuring efficiency and cost-effectiveness. Deciding what size roll-off dumpster you need revolves around accurately estimating the volume and weight of waste your venture will produce.

Volume Calculation

Different projects will yield other volumes of waste. Selecting a dumpster that’s big enough to hold all that you’re throwing away is vital.

Room Cleanouts

When clearing out a room that’s no match for your pickup truck, start by assessing the dimensions of the space. For example, a 12×15-foot room filled with old furniture, boxes, and miscellaneous junk could typically require a 10-yard dumpster. However, if you’re dealing with larger or bulkier items, or if the room is particularly cluttered, stepping up to a 15 or 20-yard dumpster might be necessary.

Imagine you’re cleaning out an attic that has become a storage area over the years. It’s not just about the square footage; it’s about the accumulated belongings. Old trunks, bookcases, and boxes of forgotten items could easily fill a 20-yard dumpster, especially if you’re unable to donate or sell any of the contents.

Construction Debris

Construction projects vary widely, from bathroom remodeling projects to new home builds. A small bathroom renovation might generate enough debris to fill a 10 cubic yard dumpster, considering the old fixtures, tiles, and possibly drywall that will be removed. In contrast, constructing a 2,000-square-foot home could require a 30-yard or even a 40-cubic-yard dumpster due to the sheer volume of material waste, such as lumber offcuts, packaging, and mixed debris.

For instance, if you’re tearing down a 500-square-foot deck, you’ll need to consider the volume of lumber and other materials involved. A 20-yard dumpster might be sufficient, but discussing your project with a Doylestown dumpster rental company for their expert recommendation is always wise.

Weight Considerations

The type of material you’re disposing of is just as important as the volume when it comes to selecting the right dumpster. Heavy materials will influence your choice because dumpsters have weight limits, and overloading can lead to additional fees.

Concrete and Brick Projects

Let’s say you’re replacing an old concrete patio that’s 300 square feet in size. The weight of concrete is substantial, necessitating a dumpster that’s designed to handle heavier loads. In such cases, a 10-yard dumpster with lower walls would be ideal for easy loading yet strong enough to handle the weight.

Mixed Material Renovations

Consider a kitchen remodel where you might dispose of old appliances, cabinetry, and flooring. The combination of materials can add up in weight. A 20-yard dumpster might be appropriate, but it’s crucial to discuss the specifics with the rental companies, as the old appliances might be particularly heavy or require special disposal considerations.


Local Regulations

Always check local regulations regarding dumpster rentals. Some areas have restrictions on the placement of dumpsters or require permits for certain sizes. For more detailed information on Montgomery County regulations, visit this article.

Remember, it’s better to err on the side of renting a slightly larger dumpster than needed rather than choosing one that’s too small. A dumpster that’s too small may require additional pickup truck loads, which can add to your project costs and timeline.

Avoiding Common Mistakes When Selecting a Dumpster

Choosing the right dumpster size is not just about waste removal; it’s about managing your project’s budget and timeline as well. One common mistake is underestimating the amount of debris a project will generate. This often results in needing a second dumpster, which can double your expected costs.

To avoid this:

  • Always Overestimate: If in doubt, choose the next size up. It’s better to have extra space than not enough.
  • Consult with Professionals: Use the expertise of your dumpster rental company. They can provide valuable advice based on experience with similar projects.
  • Account for the Unknown: Unexpected waste can appear during a project, especially with renovations. Old materials and hidden layers can increase debris.

On the other hand, you should also be cautious of the potential extra costs of choosing a dumpster that is too small:

  • Overage Fees: Exceeding the weight limit can incur hefty overage charges.
  • Additional Rentals: You may need to rent a second dumpster if the first one fills up, leading to double the haul-away fees.
  • Project Delays: Waiting for another dumpster can set your project timeline back significantly.


How to Maximize the Space in Your Dumpster

Maximizing the space within your dumpster can have significant cost benefits and efficiency gains. By loading your dumpster strategically, you can avoid the additional expense and inconvenience of renting a second container.

  • Break Down Items: Disassemble furniture and break down large items before throwing them away.
  • Load Strategically: Place flat items at the bottom and stack heavier items on top to compress the debris.
  • Fill Gaps: Use smaller debris to fill in the open spaces between larger items to minimize voids.


Financial Considerations

The cost of renting a dumpster can vary greatly depending on the size you need and the rental period:

  • Size Cost Differential: Larger roll-off dumpsters cost more to rent than smaller ones, but they are more cost-effective than renting multiple smaller dumpsters.
  • Rental Periods: Most companies offer weekly rental periods, but you can often negotiate for longer if needed. Be aware that extending the rental period can increase the price.
  • Budget for Extras: Always set aside a portion of your budget for potential overage fees or extensions in the rental period.

Remember, the cheapest option upfront may not always be the most cost-effective choice in the long run!

Regulations and Restrictions

Before renting a dumpster, you should check up on any local regulations and restrictions:

  • Permits: Some municipalities require a permit to place a dumpster on public property, such as the street. Check with your local government to see if this applies to your area.
  • Prohibited Items: Hazardous materials, electronics, and certain types of appliances are often not allowed in dumpsters due to local laws. Make sure to choose the right service for the type of material that you’re throwing away.

Failure to comply with these regulations can result in fines or the removal of the dumpster at your expense, so always do your homework before you rent.
