Sitting neatly between the popular 20ft and 40ft sizes, the 30ft shipping container is the perfect middle-ground steel box for buyers who need more than a 20ft offers but cannot justify a full 40ft. This less common length gives you generous storage and conversion space while still fitting many sites that a 40ft cannot reach. At StackCrateCo we source new and used 30ft container for sale options, every unit inspected, honestly graded and delivered across the lower 48 states. If you have been searching for that ideal in-between size, the 30ft is well worth a look.
Why choose a 30ft shipping container?
The appeal of a 30 foot shipping container is balance. It delivers around 50 percent more length than a 20ft box, which is often exactly the extra room you need for a workshop, a larger store or a roomier conversion, without the footprint and access demands of a 40ft. Because 30ft units are rarer than the standard sizes, they are prized by buyers who want something that stands out while remaining practical. The same heavy-gauge steel, lockable doors and weatherproof seals you expect from any quality container come as standard.
- Ideal middle size: more room than a 20ft, easier to place than a 40ft.
- Great for conversions: generous length for offices, studios and homes.
- Strong and secure: heavy steel, lockable doors and watertight seals.
- Distinctive: a less common length that suits unique projects.
- Versatile: storage, workshops, site offices and living space.
30ft container dimensions and capacity
A 30ft shipping container measures roughly 30ft long by 8ft wide by 8ft 6in tall externally, giving around 1,800 cubic feet of internal volume and about 240 square feet of floor space. That is a substantial amount of room, enough for the contents of a larger home, a fully kitted workshop, or a comfortable single-box conversion. High cube versions, where available, add a foot of height for taller loads and roomier living spaces. For exact internal and door measurements across every size, see our shipping container dimensions guide, and for the international build standard you can review the reference on intermodal containers.
New vs used 30ft containers
As with any container, the grade you choose drives the price. A new or one-trip box looks almost factory fresh and suits homes, offices and anything on display, while a used unit offers honest value for storage and site work.
- New / one-trip: near-pristine, ideal for conversions and customer-facing uses.
- Cargo-worthy: certified for transport, excellent structure with cosmetic age.
- Wind and watertight: sealed and dry, the budget-friendly storage choice.
How much does a 30ft shipping container cost?
Because the 30ft is a specialty length, pricing varies with availability as well as the usual factors of condition, location and modifications. Used units are the most affordable, while new one-trip boxes carry a premium for their near-new appearance. Delivery is priced transparently by ZIP code so there are no surprises. For a full breakdown of what drives pricing, read our guide on how much a shipping container costs, then check live prices and current 30ft availability in our shop.
30ft vs 20ft and 40ft containers
Choosing between the three lengths comes down to space and budget. A 20ft box is the easiest to place and cheapest, a 40ft offers the best cost per square foot for maximum volume, and the 30ft threads the needle with extra room over a 20ft while remaining more manageable than a 40ft. If you find the 20ft too small but the 40ft too large or hard to access, the 30ft is your answer. Compare our 20ft shipping containers and 40ft shipping containers to see the full range side by side.
Popular uses for a 30ft container
The generous middle length makes the 30ft a flexible performer for storage and conversions alike.
- Larger storage: more room for stock, equipment and bulky items than a 20ft.
- Workshops: space for benches, tools and projects with room to move.
- Site offices: a roomy, secure base for crews and paperwork.
- Conversions: a comfortable single-box footprint for offices, studios and homes.
- Agriculture: dry, secure storage for feed, machinery and supplies.
30ft containers for conversions
The 30ft length is a sweet spot for conversions. It offers noticeably more usable space than a 20ft, so you can include a proper living area, kitchenette and bathroom in a single box without the footprint of a 40ft. That makes it a smart base for backyard offices, studios, guest rooms and compact homes. Explore our shipping container homes and cabins ranges for ideas, and choose a one-trip unit for the cleanest starting point.
What to check when buying a used 30ft container
A good used 30ft container for sale can serve you for decades, so it pays to know what to look for. Inspect the roof for dents and pooling, the floor for soft spots, and the doors for clean opening and a tight seal. Surface rust is normal and easily treated, while deep corrosion is a warning sign. At StackCrateCo we carry out this inspection for you and grade every unit honestly, so you never gamble on an unseen box.
- Doors: should swing freely and seal against the gaskets.
- Floor: solid marine plywood with no rot.
- Roof: no major dents or standing water.
- Frame: straight rails and sound corner castings.
Modifying your 30ft container
The 30ft adapts as readily as any container. Add personnel or roll-up doors, cut in windows and vents, line and insulate the walls, or fit shelving and power to create a workshop or office. The strong structure means most modifications are straightforward, and the extra length over a 20ft gives you more design freedom. Finish the job with genuine container accessories such as lock boxes, vents, shelving and ramps.
Delivery of your 30ft container across the USA
We deliver every 30ft shipping container nationwide from our Sauget, Illinois depot using tilt-bed and flatbed transport. Tilt-bed needs no equipment and slides the container gently onto a level surface, while flatbed suits sites with a forklift or crane. The 30ft length is more manageable than a 40ft, so access is often easier on restricted sites. Delivery is priced by distance from your ZIP code at checkout, so the figure you see is the figure you pay. Confirm coverage and access on our delivery areas page.
How to prepare for delivery
A 30ft container needs a firm, level spot and clear access for the delivery truck. For tilt-bed delivery, allow generous straight clearance so the driver can angle the bed and roll the box off smoothly. A bed of gravel or sleepers keeps the container off wet ground and helps the doors stay square. Our team will confirm site requirements when you order so the drop goes cleanly first time.

30ft container grades explained
Understanding the grades helps you buy a 30ft shipping container with confidence. One-trip units are the newest available, having shipped just once, so they show minimal wear and the cleanest paint, which makes them ideal for homes, offices and anything on display. Cargo-worthy boxes remain certified for international transport and are structurally excellent with cosmetic age. Wind and watertight units are sealed and dry but no longer cargo-certified, offering the most affordable route to secure, weatherproof storage. As-is containers are sold for their steel value and suit only specific projects. Every 30 foot shipping container we offer carries a clear grade, so you always know exactly what you are buying and never pay for condition you do not need.
Stacking, strength and durability
Like every container we sell, the 30ft is engineered to survive the rigours of ocean and road transport. Its corner castings and steel frame are designed to be stacked and lifted when fully loaded, so a single unit on your site is exceptionally robust. Corrugated steel walls shrug off impacts and weather, marine-grade plywood floors carry heavy point loads, and the whole structure is built to last. For buyers, that means a low-maintenance, long-lasting steel building block. With a level base, occasional rust treatment and well-kept door seals, a 30ft container stays watertight and structurally sound for 25 years or more, making it a genuine long-term investment rather than a disposable store.
The sustainable choice
Buying a used 30ft container for sale is one of the greenest building decisions you can make. Each box is a massive, ready-made steel structure that would otherwise sit idle, so repurposing it keeps valuable steel in productive use rather than the scrap yard. Compared with pouring concrete or framing a new structure of similar size, reusing a container dramatically cuts the material footprint of your storage or build. It is durability and sustainability in a single rugged package, which is part of why container projects appeal so strongly to environmentally minded buyers.
