Dumpster Sizes Guide
Not sure which size you need? Compare dimensions, capacities, and ideal project types for every standard dumpster size. Visual comparisons make it easy to choose with confidence.
What size dumpster do I need?
A 10 yard handles a single room or garage cleanout, a 15 or 20 yard covers a whole-house cleanout or a kitchen or bath remodel, and a 30 or 40 yard is for construction, demolition or a large roof. Heavy material like concrete or dirt goes in a smaller heavy-material box, because weight fills a dumpster long before volume does.
Ultimate Dumpsters offers roll-off dumpsters in 10, 20, 30, and 40-yard sizes. A 10-yard holds about 3 pickup truck loads and suits small cleanouts and single-room remodels, a 20-yard holds about 6 loads for whole-room renovations and roofing, a 30-yard holds about 9 loads for large renovations and construction, and a 40-yard holds about 12 loads for major demolition and commercial jobs. When you are between two sizes, choosing one size up costs far less than renting a second container.
What Does "Cubic Yards" Mean?
Dumpster sizes are measured in cubic yards. One cubic yard is a space that measures 3 feet long, 3 feet wide, and 3 feet tall, about the size of a kitchen stove. When we say a dumpster is "20 yards," it means the container holds 20 cubic yards of debris, or roughly the equivalent of 6 full-size pickup truck loads.
The physical dimensions of the dumpster do not directly correspond to the cubic yardage because containers vary in length, width, and height. A 10-yard and a 20-yard dumpster may be the same length but the 20-yard has taller sides, giving it more capacity. Understanding this distinction helps you avoid ordering too small or paying for space you do not need. Volume is only half the picture: check our dumpster weight limits guide before you load heavy debris, and see the dumpster rental pricing guide for how size maps to cost.

Size Recommendations by Project Type
Home Cleanout
Recommended: 10 to 20 yard
A single room is usually a 10-yard. Whole-house cleanouts often require a 20 or 30-yard.
Roofing Project
Recommended: 20 to 30 yard
Roofing shingles are heavy. A 20-yard handles up to 30 squares; larger roofs need a 30-yard.
Construction / Demolition
Recommended: 30 to 40 yard
Construction generates high-volume debris. Go with 30 for remodels, 40 for teardowns.
Yard Waste / Landscaping
Recommended: 10 to 20 yard
Branches and soil are heavy but compact. A 10-yard is often enough unless you are clearing a large property.

Frequently Asked Questions
The 10-yard and 20-yard dumpsters are the most popular sizes for homeowners. A 10-yard works great for small cleanouts and single-room remodels, while a 20-yard handles most medium-sized projects like kitchen renovations, roof replacements, and multi-room decluttering.
Measure the length, width, and height of your debris pile in feet, then multiply all three numbers together and divide by 27. For example, a pile that is 6 feet long, 4 feet wide, and 3 feet high equals 72 cubic feet, or about 2.7 cubic yards. Our size calculator can help with this estimate.
If your dumpster fills up before your project is complete, you have two options. You can schedule a swap where we pick up the full container and deliver an empty one, or you can upgrade to a larger size. There may be additional fees for the extra trip, so it is generally more cost-effective to go one size up from the start.
While it is possible, 40-yard dumpsters are very large: 22 feet long, 8 feet wide, and about 8 feet tall. Most residential driveways can accommodate them, but you need significant clearance. These containers are more commonly used on commercial and construction sites. For most home projects, a 20 or 30-yard is sufficient.
Yes. Larger dumpsters cost more because they hold more debris and require larger trucks for transport. However, the price per cubic yard often decreases as you go up in size, making larger containers more cost-effective for bigger projects. A 20-yard dumpster typically costs 30 to 40 percent more than a 10-yard, not double.
Dumpster wall heights vary by size. A 10-yard container has sides about 3.5 feet high, making it easy to load by hand. A 20-yard is about 4.5 feet, a 30-yard is about 6 feet, and a 40-yard reaches roughly 8 feet. All dumpsters have a rear swing door that you can open for walk-in loading of heavy items.
