What Size Dumpster Do I Need? Complete Selection Guide 2025
What size dumpster do I need? Compare 10–30 yard options by project type, capacity, and price. Includes a simple decision tree.
The quick answer by project type
Most people overthink this. Here is the short version I give on the phone. A small cleanout, a single bathroom, or a tight driveway: 10 yard. A one-room remodel, a garage cleanout, or a small deck: 15 yard. A kitchen remodel, a basement cleanout, or a small roof: 20 yard. A whole-house cleanout, a large roof, or a major demolition: 30 yard. If you are between two sizes, take the bigger one.
How the sizes compare
A 10 yard dumpster holds about four to five pickup truck loads and is the easiest to place on a short driveway. A 15 yard dumpster holds six to seven loads with lower walls that are easy to load. A 20 yard dumpster holds eight to nine loads and is the same footprint as the 30, just shorter. A 30 yard dumpster holds twelve to fourteen loads with taller walls for big, multi-day projects.
Volume is only half the story. Weight matters just as much. Light, bulky debris like drywall, wood, and household junk fills a container before it gets heavy. Dense debris like concrete, tile, dirt, and shingles can hit the weight limit while the container still looks half empty. If your load is heavy, say so when you book and we will set the right allowance.
A simple decision tree
Start with how many rooms or phases the project covers. One small room or a tight space points to the 10 or 15. Two rooms or a whole basement points to the 20. The whole house, a large roof, or a construction site points to the 30. Then check your placement spot: measure the length you have available and look up for low wires or branches. The 20 and 30 need about 22 feet of clear length.
Finally, think about pace. If the project runs over several days and the pile will grow, size up. Unused space costs a few dollars; a second haul or an overage costs a lot more. That single rule prevents most of the regrets I hear about.
