A 20 yard dumpster typically holds 2 to 3 tons before hitting its weight cap, and a 30 yard runs 3 to 4 tons depending on what you're throwing in it. Go over and you'll pay overage fees by the ton. Medford Porta Pros builds the weight allowance into your quote so there's no surprise at pickup.
Most 30 yard containers are rated for 3 to 4 tons of mixed debris, though that number swings hard based on material. A yard of shingles weighs a lot more than a yard of old furniture, so how many tons a 30 yard dumpster can hold really depends on density, not volume. Renovation crews in Medford filling a 30 yard dumpster rental with drywall and framing lumber usually stay under the cap without thinking about it. Concrete, dirt and roofing material are the loads that push weight limits fast, and those often call for a dedicated construction dumpster rental sized for heavier debris. Check dumpster weight limits against your material type before you order, and compare it against a 20 yard dumpster rental if your job runs lighter. Pricing in the table below reflects a standard container, not a heavy-debris load.

A 20 yard dumpster generally holds 2 to 3 tons, which covers most single-room demolitions, garage cleanouts and roofing tear-offs under a couple thousand square feet. An empty 20 yard container itself weighs somewhere in the neighborhood of a few thousand pounds before you add anything, so know that the truck is already carrying tare weight before your debris goes in. If you're not sure which size fits, the dumpster sizes and dimensions page breaks down footprint alongside capacity. Homeowners in Medford doing a kitchen gut often start here, and it pairs well with a home renovation porta potty if the crew is on site for more than a day. For heavier hauls, the 40 yard dumpster rental or a 10 yard dumpster rental for smaller jobs both carry different tonnage math, so match the container to the material, not just the mess.
Certain materials get restricted or banned outright because they blow past weight allowances fast, tires, wet concrete, and full paint cans among them. Full details live on what cannot go in a dumpster, and it's worth a read before loading day. OSHA 1926.25 requires scrap and debris to be cleared from work areas regularly, which matters on active job sites where a container fills faster than expected. OSHA 1926.252 covers disposal chutes and enclosures for construction waste, relevant if you're loading from height on a multi-story job in Medford. If your project needs formal permitting for street placement, see dumpster permit requirements since city rules on right-of-way placement need confirming directly with Medford before delivery day. A roll-off delivery needs about 60 feet of straight clearance behind the truck, so measure your driveway or curb space in advance.
Weight, not volume, is what triggers overage charges, because haulers price by the ton past your included allowance. A homeowner in Winchester, 3.7 miles northwest of Medford, filling a 20 yard with roofing shingles will hit tonnage long before the container looks full. Compare that to someone in Woburn, 6.0 miles northwest, tossing bulky but light furniture into the same size box; they'll run out of room before they run out of weight allowance. This is true whether you're renting in Medford or comparing notes with a roll-off dumpster rental Dayton Ohio crew or a roll-off dumpster rental San Antonio job, the pricing logic is the same nationwide. Review dumpster rental cost and dumpster weight limits together before booking so the estimate matches your actual debris type.
| unit | duration | low | typical | high |

| dumpster | weekend | 390 | 440 | 497 |
| dumpster | week | 426 | 600 | 778 |
| dumpster | month | 91 | 108 | 500 |
Prices assume standard mixed debris within the container's rated weight allowance. Heavy material like concrete, dirt or roofing shingles may need a different container class or a flat per-ton arrangement, so ask when you request a quote.
An empty 20 yard dumpster weighs a few thousand pounds on its own, before any debris goes in. That tare weight is factored into what the truck can legally haul, which is part of why weight caps exist at all. Ask Medford Porta Pros for the specific tare weight on your container if you're calculating close to the limit.
You'll be charged an overage fee per ton beyond your included allowance, billed after the container is weighed at the facility. It's not a flat penalty, just a per-ton rate added to your invoice. Ask for the per-ton overage rate up front so there are no surprises on the final bill.
Not directly. Size sets the volume, but tonnage depends on what you put in it. Heavy material like concrete fills the weight cap long before the container looks full, while bulky light items like furniture can fill the space without ever approaching the ton limit.
Usually yes, but check restricted material rules first. Some items are banned outright regardless of weight, covered on what cannot go in a dumpster. Mixing dense material like tile with lighter household debris is common and generally fine within the standard weight allowance.
Match debris type to size, not just estimated volume. A renovation producing heavy material needs a smaller container with more weight allowance, while a cleanout with bulky light items can use a larger box. The how many porta potties do I need page covers sizing logic for restrooms, and similar logic applies here: describe the job to Medford Porta Pros and get a size matched to weight, not guesswork.
Yes. Medford Porta Pros delivers dumpster weight limits across Medford and the surrounding metro, with same-day and next-day drop-off available on most orders.
