What Sized Dumpster Do I Need?

Jack Reed • November 22, 2024

Choosing the correct dumpster size is more than a matter of convenience—it can make or break the efficiency and cost-effectiveness of your project. Whether you’re cleaning out your home, renovating a kitchen, or managing a construction site, selecting the wrong size can lead to unnecessary delays, fees, and frustration.


Here are some common issues you can avoid by taking the time to assess your project and select the right dumpster size:

Why Choosing the Right Dumpster Size Matters

Overloading Small Dumpster Sizes

A dumpster that’s too small for your project can quickly become a headache:


  • Additional Fees: Overloading can lead to extra charges for exceeding weight limits or needing additional pickups. For example, filling a 12-yard dumpster with heavy materials like concrete may surpass its weight capacity, even if it looks like there’s space left.


  • Project Delays: When a small dumpster fills up mid-project, you’ll have to pause everything to wait for a replacement or arrange extra trips to the landfill.


Solution: It’s always better to slightly overestimate your waste volume and choose a size that allows extra room for unexpected debris.


Renting a Size Too Large

While it might seem safe to go bigger, renting a dumpster that’s unnecessarily large comes with its own drawbacks:


  • Higher Costs: Larger dumpsters are more expensive, and if you’re not filling the container, you’re essentially paying for unused space.


  • Limited Placement Options: Bigger dumpsters require more space for delivery and setup. In residential areas, a 30-yard or 40-yard dumpster may not fit comfortably in a driveway, creating logistical issues.


Solution: Match the dumpster size to your specific project type and waste volume. For example, a 12-yard dumpster is perfect for moderate home cleanouts, while an 18-yard dumpster handles larger residential or small commercial jobs.

Understanding Volume, Weight Limits, and Project Type

The key to avoiding these pitfalls is understanding the relationship between volume, weight limits, and the type of project you’re tackling:


  • Volume: Dumpsters are measured in cubic yards, and one cubic yard equals about 5–6 standard trash bags. Knowing your project’s debris size helps you estimate the volume needed.


  • Weight Limits: Each dumpster has a maximum weight it can safely carry. Heavy debris like concrete or bricks adds up quickly, so even a small dumpster can reach its limit. Choosing the right size ensures compliance with these restrictions.


  • Project Type: Some projects, like yard cleanups, produce lightweight waste that takes up more space, while others, like roofing, generate heavy but compact debris.


By understanding these factors, you can avoid unnecessary costs, prevent delays, and ensure your project runs smoothly from start to finish.

3 Factors to Select the Right Size

Choosing the best dumpster requires assessing your project needs. These three factors help guide your decision:


Type of Debris

Different waste types require different considerations:

  • Light Waste: Items like furniture, household junk, or yard debris fit well in smaller dumpsters.
  • Heavy Debris: Concrete, bricks, or roofing materials often need smaller dumpsters to stay within weight limits.
  • Restricted Items: Many companies do not handle hazardous materials like chemicals or electronics may require special handling.


Total Volume

Estimating your waste volume is key to selecting the right size. Use this simple formula:

Cubic Yards = Length (ft) × Width (ft) × Height (ft) / 27

For example:

  • A pile of waste measuring (12' x 6' x 3') / 27 = 8 cubic yards.
  • Round up to the nearest dumpster size to ensure you have enough space.


Delivery Location

Consider where your dumpster will be placed:

  • Residential: Driveways, small lots, or limited curb space may work best with compact sizes like 10 or 12 yards.
  • Commercial: Larger spaces like construction sites or retail lots can accommodate bigger equipment and dumpsters like 20 or 30 yards.

    Whether you’re updating your kitchen or tackling a bathroom remodel, our 18-yard dumpster offers ample space for drywall, flooring, and cabinets. Larger remodels may require a 20-yard dumpster for maximum efficiency.

  • Roofing:

    Recommended Size: 12 or 18 yards

    From asphalt to slate shingles, roofing debris adds up quickly. Our 12-yard dumpster is ideal for smaller roofs, while the 18-yard option is better for larger homes. Both sizes handle the weight safely.

    Our 12-yard dumpster is great for yard cleanups involving branches, leaves, or grass clippings. For larger landscaping overhauls involving stumps, soil, or sod, consider the 18-yard option for added capacity.

Frequently Asked Questions About Choosing the Right Dumpster Size

  • What does "dumpster size" mean?

    "Dumpster size" refers to the amount of material a container can hold, measured in cubic yards. For example, a 10-yard dumpster holds 10 cubic yards of waste, whether it's heavy debris like dirt or lighter items like household junk.


  • How do I calculate the size of the dumpster I need?

    To calculate the size of the dumpster you need, measure the length, width, and height of your trash pile (in feet) and divide by 27. This gives you the cubic yardage.


  • What happens if I rent a dumpster that’s too small?

    If you rent a dumpster that’s too small, you risk exceeding the load capacity, leading to extra rental costs or project delays while waiting for a second container.


  • Is it better to rent a dumpster that’s too big?

    Yes, renting a larger dumpster ensures you have enough space, especially if you’re unsure about the volume of your project debris. However, be cautious of renting unnecessarily large dumpsters, as this increases rental expenses.


  • How do I estimate the weight of my waste?

    To estimate the weight of your waste, consider the material:

    • Household trash: ~100–200 lbs per cubic yard.
    • Dirt or bricks: ~4,000 lbs per cubic yard.
    • Roofing materials: ~250 lbs per square of shingles.
  • What size dumpster do I need for a home cleanout?

    For a home cleanout, a 12-yard dumpster is ideal for average junk removal or cleaning out a single room. For larger cleanouts involving furniture or appliances, a 15- or 18-yard dumpster may be more suitable.


  • Can I use the same dumpster for multiple types of debris?

    Yes, you can use the same dumpster for multiple types of debris, such as trash and heavier materials like bricks or dirt. However, make sure the combined weight doesn’t exceed the limit for the size you choose.


  • Are there dumpsters designed specifically for heavy debris?

    Yes, smaller dumpsters like 12-yard or 10-yard options are better for heavy debris like concrete, dirt, or bricks because they stay within weight limits, even if fully loaded.

  • How much space does a dumpster need for delivery?

    A dumpster needs enough space for the container and the delivery truck. A 12-yard dumpster typically requires 12 feet of length, 6 feet of width, and clear access for the truck.
