ALL THE DEBRIS THAT'S FIT TO DUMP
The 30 yard is the big-job container, the one people reach for on a whole-house cleanout, a real renovation, a roof, or a construction haul. Here is what it actually holds, how big it is, and the honest read on when you need it over a 20 yard, so you rent the right box instead of defaulting to the biggest one and paying for air.

The 30 yard roll-off is the size people search for when the job got big. It holds about 30 cubic yards of debris, which is roughly nine pickup truck loads, or somewhere around 170 to 190 filled trash bags. It measures about 22 feet long, 7.5 feet wide, and 6 feet tall, and those 6 foot walls are the whole point: they are taller than a 20 yard, so bulky, high-volume material stacks up instead of maxing out the footprint. A standard 30 yard rental includes a 3 ton, 6,000 pound, weight allowance, and runs about 650 to 995 dollars all-inclusive across the markets we serve, delivery, pickup, disposal and a week of rental in one flat number.
What actually fits a 30 yard is high-volume work, not heavy work. A whole-house cleanout, a multi-room or whole-home renovation, a big roofing tear-off, a garage plus basement plus attic all at once, or construction and demolition debris that comes in bulky and fast. If you can picture the pile filling the bed of a pickup nine times over, that is a 30. The taller walls are what make it the right call for anything that is big in size rather than dense in weight, because you can keep loading up instead of running out of floor.
Now the honest part, the one most companies skip: a 20 yard already handles more than people think. A 20 yard holds about 20 cubic yards, measures 22 by 7.5 by 4.5 feet, and comes with a 2 ton allowance, and it covers most whole-house cleanouts and larger remodels just fine. So if your job is a single-room remodel, a garage or basement cleanout, a small roof, or a yard and deck teardown, the 20 is usually enough, and it is cheaper. The trap is renting the 30 as a safety margin. You do not pay for the space you do not fill, you pay for the container, so an oversized box is just money left in the driveway. Rent the 30 when you genuinely expect to fill more than a 20, or when the material is bulky enough to need the taller walls, not just in case.
There is one thing the 30 yard does not fix, and it is worth saying plainly: it does not carry more weight than its allowance, it carries more volume. Heavy material like concrete, dirt, brick, or roofing shingles hits the weight limit long before it fills the box, which is why those jobs usually go in a smaller, weight-rated clean load rather than a big 30. So the real question is never just how big is the pile, it is big-and-light or small-and-heavy. Big and light is the 30 yard job. Small and heavy is a 10 or a clean load. Getting that one distinction right is the difference between a smooth haul and an overage bill.
So the takeaway from the 30 yard desk is simple. The 30 is for big-volume, bulky jobs, whole-house, renovation, roofing, construction, and it holds about nine pickup loads behind six-foot walls. Below that, a 20 yard is usually the smarter, cheaper buy, and we will tell you so rather than upsell you. And if the material is heavy rather than bulky, the answer is a smaller weight-rated box, not a bigger one. Tell us the job and the heaviest thing going in, and we size it right the first time, at one flat price you can see before you book.

The 30 yard holds about 30 cubic yards, roughly nine pickup truck loads, behind six-foot walls. Pick by the volume and bulk of the job, and drop to a smaller weight-rated box for heavy material like concrete or dirt.
“The 30 yard is a volume box, not a weight box. If the pile is big and light, whole-house, renovation, roofing, that is the 30. If it is small and heavy, concrete or dirt, a big container just hits the weight limit half-empty. Tell me the heaviest thing going in and I will size it right the first time.”

People reach for the 30 to be safe, and half the time a 20 would have done it for less. You pay for the container, not the air in it. I will tell you when the 20 is enough, that is the whole job.
The six-foot walls are the tell. A 30 is right when the material is bulky and stacks up, framing, roofing, whole-house junk. For anything dense and heavy, we drop you to a smaller clean load so you are not paying overage on a half-full box.
A 30 yard dumpster holds about 30 cubic yards of debris, which is roughly nine pickup truck loads or about 170 to 190 filled trash bags, and it measures about 22 feet long, 7.5 feet wide, and 6 feet tall with a 3 ton weight allowance. Choose a 30 yard for high-volume jobs like a whole-house cleanout, a large renovation, a roofing tear-off, or construction and demolition debris. A 20 yard holds about 20 cubic yards, measures 22 by 7.5 by 4.5 feet, and already handles most whole-house cleanouts and larger remodels, so if your job is a single room, a garage or basement cleanout, or a small roof, the 20 yard is usually enough and cheaper. Rent the 30 when you genuinely expect to fill more than a 20 or the material is bulky enough to need the taller walls, and drop to a smaller weight-rated box for heavy material like concrete or dirt.
