Dumpster Size Calculator

Not sure which dumpster size you need? Answer three quick questions about your project and we will recommend the best size, plus show you how it compares to all available options.

Step 1 of 3Project Type

What type of project are you working on?

Select the option that best describes your project. This helps us estimate the type and volume of debris.

How the Size Calculator Works

Our calculator uses data from thousands of completed dumpster rentals to match your project to the right container. We factor in three things: the type of project you are doing, the estimated volume of debris, and whether you have any heavy materials like concrete or dirt.

Heavy materials take up less space but add significant weight. A 10-yard dumpster full of concrete can weigh over 10 tons, well above the 1-2 tons of weight included with smaller containers. That is why our calculator recommends a larger size when heavy materials are involved, giving you more capacity while staying within weight limits.

Keep in mind that this is a starting recommendation. If you are between sizes or your project scope changes, our team can help you adjust. You can also use our Weight Estimator for a more detailed weight analysis, or our Cost Calculator to see estimated pricing.

Dumpster Size Calculator FAQ

Common questions about choosing the right roll-off dumpster size.

For most home projects a 10-yard dumpster handles small cleanouts and single-room remodels, a 20-yard fits whole-home cleanouts and mid-size renovations, and a 30 or 40-yard suits large construction and new builds. Our calculator asks about your project type, debris volume, and whether you have heavy materials, then recommends the best fit. When you are between two sizes, going one size up is almost always cheaper than ordering a second dumpster.

A 10-yard dumpster (about three pickup-truck loads) is right for a single room, a small bathroom or kitchen tear-out, or a garage cleanout. A 20-yard dumpster (about six pickup loads) is the most popular size and handles a full-home cleanout, a large flooring or roofing job, or a multi-room remodel. If you are doing a full renovation or new construction, step up to a 30 or 40-yard.

Yes. Heavy materials like concrete, brick, dirt, and asphalt take up little space but hit the weight limit fast, so the calculator recommends a larger container to stay under the included tonnage. Light, bulky debris like furniture, drywall, or yard waste fills up by volume instead. Tell the calculator if you have heavy material and it adjusts the recommendation accordingly.

If you overfill a container past the fill line the hauler cannot legally transport it, which can mean a return trip, an overage fee, or a second rental. Choosing the right size up front avoids all of that. When in doubt, our team places thousands of these every month and can confirm your pick before you book.
