Container library: sizes, interior dimensions, and payload capacity

Interior dimensions and payload for shipping containers, trailers, trucks, air cargo ULDs, railcars, and pallets. Browse any type online, then import it straight into your Truck Packer container inventory.

Shipping Containers
14 containers

Internal dimensions and payload for every common ISO ocean container, from the 10ft box to the 45ft pallet-wide high cube, plus reefers, open tops, and flat racks.

Semi-Trailers
13 containers

Interior cargo dimensions and payload for US and European semi-trailers: 53ft and 48ft dry vans, reefers, flatbeds, step decks, lowboys, and the 13.6 m European artic.

Box Trucks
17 containers

Cargo box dimensions and payload for commercial straight trucks and vans by class, from cargo vans and Luton bodies up to 26ft box trucks and European 26t rigids.

Rental Trucks
12 containers

Interior cargo dimensions, volume, and payload for every common self-serve rental truck from Penske, U-Haul, and Budget, 10 ft to 26 ft, in one sortable table.

Air Cargo ULDs
16 containers

Dimensions and maximum gross weight for the IATA unit load devices air freight actually moves on: LD-series lower-deck containers and PMC, PAG, PLA, and PGA pallets.

Rail Cars
4 containers

Inside dimensions and load limits for the boxcars and rail intermodal boxes that carry general freight by rail in North America and Japan.

Pallets
7 containers

Footprints and load ratings for the pallet standards that decide how everything else packs: the GMA 48 x 40, the Euro EPAL, and the ISO 6780 footprints used across Asia and Australia.

Every container size, in one place

Load planning starts with one question: how big is the space? It sounds trivial until you go looking, and find that the answer is scattered across carrier spec sheets, ISO standards, rental storefronts, IATA documentation, and a lot of blog posts quoting each other. The Container Library pulls it into one place. Each group below covers one class of cargo space with its interior length, width, and height, its cargo volume, and its payload capacity, with a link to the published source for every row. Whether you are deciding between a 40ft and a 40ft high cube, checking whether a rig fits a 26 ft box truck, working out how many LD3s a shipment needs, or confirming that two Euro pallets will sit abreast in a pallet-wide container, the number you need is here.

From a size on a page to a 3D load plan

Knowing the dimensions is only half the job. The reason to look them up is almost always to answer a downstream question: does it all fit, in what order, and what does the crew load first. Every container on these pages can be imported directly into a Truck Packer inventory in one click, dropped into a pack, and packed against with AutoPack. Pair a container from this library with a case library from the manufacturer library and you can plan an entire trailer, container, or ULD build-up without a tape measure, then hand the crew a load order and a printable label set.

Frequently asked questions

What is the Truck Packer Container Library?
A free reference of interior dimensions and payload capacity for the cargo space freight actually moves in: ISO shipping containers, semi-trailers, box trucks, rental trucks, air cargo ULDs, rail boxcars, and pallets. Every figure is the published specification of the manufacturer, carrier, or standards body linked on each row. The same data can be imported straight into a Truck Packer container inventory, so you can lay out a 3D load plan against a real piece of equipment rather than a guess.
Are these interior or exterior dimensions?
Interior, wherever the concept applies. A 40ft container is 40 feet long on the outside but gives about 473.7 in of usable length inside, and a 26 ft box truck name refers to the cargo box, not the overall vehicle. For open equipment such as flatbeds and pallets the height shown is a load-planning height rather than a physical ceiling, and the page for that group says so.
What units are the numbers in?
Dimensions are in inches, volume in cubic feet, and payload in pounds, matching the rest of the Truck Packer libraries. Truck Packer itself supports both metric and imperial, and converts on import, so importing into a metric organization gives you metres and kilograms automatically.
Is payload the same as gross weight?
No, and confusing the two is the most common load-planning mistake. Payload is the maximum weight of cargo. Gross vehicle weight or gross container weight includes the equipment itself, which can be several tonnes. Every payload figure in this library is cargo weight. On the road the binding limit is usually the legal gross combination weight rather than the trailer rating, so check local axle rules before loading to the maximum.
How do I get these containers into Truck Packer?
Open Truck Packer, go to Containers, and open the Container Library: pick a group and import the whole set, or add individual containers one at a time. No files to download and no columns to map. Once a container is in your inventory you can drop it into any pack and run AutoPack against it.
How accurate are these figures?
They are captured as published, and each row links to its source. Real equipment varies by make, model, year, and operator, and rental companies say as much themselves. Treat them as planning numbers and confirm the specific unit before you load it. If you spot a discrepancy, email help@backlinelogic.com with the container name and we will update it.
Can you add a container type that is missing?
Yes. Tank containers, curtain-side rigids, additional regional truck classes, and more freighter ULDs are all candidates. Email help@backlinelogic.com with the equipment and a link to its published specification and we will add it to the library.
