What are the dimensions of a 10 yard dumpster?
A 10 yard dumpster measures roughly 12 feet by 8 feet with side walls around 3.5 feet high. That is small enough to tuck into a driveway or a tight lot in Kent without eating the whole yard. It holds about three pickup truck loads, which fits a bathroom tear-out, a garage cleanout or a small home renovation porta potty project running alongside it. 10 yard dumpster measurements matter most when clearance is the problem, not volume. If your access point is narrow, this is the size to ask about first. Kent Porta Pros still needs the standard drop clearance behind the truck, about 60 feet of straight room, the same clearance every roll-off dumpster rental needs regardless of box size. Check the full dumpster sizes and dimensions breakdown against your load estimate before locking in a size, because guessing low costs more than the size upgrade would have. Pair it with a 10 yard dumpster rental quote and confirm placement using our porta potty placement guide logic, which applies to box placement too.
What are 20 yard dumpster dimensions?
20 yard dumpster measurements land around 22 feet long, 8 feet wide and 4.5 feet tall, roughly double the depth of a 10 yard on a similar footprint. That extra wall height is what fools people. The 20 yard dumpster size handles a full roof tear-off, a deck demo, or a multi-room remodel where debris piles up fast. It is the size we quote most for mid-size jobs across Kent, and the one most often confused with the 30 yard because the length looks close on paper. Check 20 yard dumpster rental pricing directly rather than assuming it scales evenly from the 10 yard, since delivery and hauling costs move differently by weight, not just volume. If you are unsure which way to round, our dumpster rental cost page walks through the tradeoff, and what cannot go in a dumpster is worth a read before you fill either size with anything that changes the weight class fast, like wet drywall or shingles.
What is the 30 yard dumpster size?
A 30 yard dumpster keeps the same rough footprint as the 20 yard but stands about 6 feet tall, which is chest height for most adults loading it by hand. That height difference is the real story behind the 30 yard dumpster size, not the length. It is built for construction debris, whole-house cleanouts, and commercial strip-outs where volume outruns weight. Contractors running a construction dumpster rental alongside active framing or demo crews tend to land here rather than jump straight to a 40. Loading over the wall gets harder past shoulder height, so plan for a ramp or a lift if the crew is loading heavy sheet goods by hand. Kent Porta Pros checks dumpster weight limits with every 30 yard quote, because weight, not just fill line, is what triggers overage charges on the bigger boxes. If your load is dense material like concrete or tile, a smaller box under weight often beats a bigger box over it.
Which dumpster size fits my project?
The honest answer depends on what you are hauling, not just how big the pile looks. A kitchen gut job in Kent usually fits a 20 yard. A full home cleanout or a small commercial strip-out usually needs a 30, and anything larger than that points toward the 40 yard dumpster rental. Weight matters as much as volume: a 10 yard full of shingles can hit its weight cap long before it looks full, while a 20 yard of bulky furniture might never get close. Walk the site before you order and measure your access point, since delivery trucks need that 60 foot straight approach whether you book a 10 or a 40. If the job is a renovation with a bathroom out of service, pair the dumpster with a porta john rental or a full portable restroom rental so the crew has a place to go while the water is shut off.
Do I need a permit for dumpster placement in Kent?
Permit rules depend on where the box sits, and placement in the public right of way needs confirming with the city before delivery. If the dumpster stays fully on private property, driveway or lot, permitting is rarely an issue, but curb or street placement is a different question entirely. Read dumpster permit requirements before delivery day so there is no scramble once the truck is on its way. This is also the point to double check dumpster weight limits and confirm your box size against the actual scope, since resizing after delivery costs more than getting it right the first time. Kent Porta Pros handles delivery logistics for storage container rental jobs the same way, checking access and placement before the truck rolls.
Comparing the three sizes
| size | length | width | height | best for |
|---|---|---|---|---|
| 10 yard | 12 ft | 8 ft | 3.5 ft | small cleanouts, tight driveways |
| 20 yard | 22 ft | 8 ft | 4.5 ft | remodels, roof tear-offs |
| 30 yard | 22 ft | 8 ft | 6 ft | whole-house jobs, active construction |
How much space do I need for delivery?
Plan for about 60 feet of straight clearance behind the truck, regardless of which box size you order. That number does not change between a 10 yard and a 30 yard. Tight alleys or short driveways in older Kent neighborhoods sometimes need a placement conversation before the truck shows up, so call ahead if access looks marginal.
Can I put construction debris and household junk in the same dumpster?
Usually yes, but not everything is allowed regardless of size. Check what cannot go in a dumpster first, since items like tires, batteries and certain chemicals get rejected at the dump and billed back to you.
How long can I keep a rental dumpster?
Rental periods run by the day, week or month depending on your project timeline. A short cleanout might only need a day or two, while an active renovation often runs a full month. Ask Kent Porta Pros to match the rental window to your actual schedule.
Does dumpster size affect weight limits?
Not directly. A smaller box can hit its weight cap before it looks full if you are loading dense material like tile or concrete. Review dumpster weight limits before choosing size based on volume alone.
What is the difference between a 20 and 30 yard box?
Mostly wall height, not length. Both share a similar footprint, but the 30 yard stands about 6 feet tall versus 4.5 feet on the 20 yard, which changes how easily crews can load it by hand.
