A twenty foot container is built for one car, and when you are shipping one car it is very often the sensible and cheaper booking. Where it gets interesting is at the margins: whether something small enough can share it, what else can travel around the vehicle, where the weight limit bites, and when you are actually better off paying for a bigger box. This page works through those decisions.
One car, and the one exception
A twenty foot container takes one vehicle. That is what the box is sized for and that is what it does well, and in the great majority of cases there is no second car to be had out of it at any price.
The exception is a vehicle small enough that two of them genuinely fit, and in practice that means something on the scale of a Smart car. Two of those will go into a twenty foot container. Anything appreciably larger will not, whatever is claimed, and a quote built on the idea that it will is a quote that falls apart at the warehouse. If you think your vehicle might fall into that category, send us the model and we will measure it against the box rather than guess.
For two ordinary cars, a forty foot high cube is the answer and it is usually cheaper per vehicle than two twenty foot containers would be. Our container loading guide sets out the numbers across all the sizes.
When a 20ft is the cheaper booking
If you are moving one vehicle and nothing else, the twenty foot is usually the better value. The ocean freight on the smaller box is lower on most lanes, the handling is the same, and you are not paying for space you cannot use. On routes where equipment is tight, there is also often better availability on twenty foot containers than on forty foot high cubes, which can mean an earlier sailing.
Where the comparison flips is when you have more to send than you first thought. The cost gap between the two boxes on most lanes is smaller than people expect, and the moment a second vehicle, a motorcycle, a pallet of parts or a quantity of spares comes into the picture, the forty foot high cube usually wins on cost per item by a comfortable margin. It is worth telling us everything you might send before you book rather than only what you have decided on.
Height is the thing to check
A standard twenty foot container has an internal height of a little under eight feet, and a door opening lower than that. Most sedans, hatchbacks and small crossovers go in without difficulty. Where people run into trouble is with tall vehicles: full size pickups, large sport utility vehicles, vans and anything with a roof rack, a light bar or a lifted suspension.
A tall vehicle may still fit a twenty foot container with the suspension deflated, the roof fittings removed, or the tires let down, and we do that regularly. But it has to be checked against the specific vehicle rather than assumed from the class, because the difference between a model that fits and one that does not is often only an inch or two. Send us the year, make and model and we will check the figures against the box. You can see the internal dimensions yourself on our shipping tools page.
For a vehicle that genuinely will not go in at any reasonable effort, a forty foot high cube gives you the extra height and is the straightforward answer.
What else can travel with the car
There is real usable space around a vehicle inside a twenty foot container, in front of it, behind it and along the sides, and filling that space is one of the most efficient things you can do. Spare parts, wheels and tires, boxed items and tools all travel well there and cost very little extra in freight.
Everything has to be declared before the container is sealed. Each item appears on the United States export filing and on the bill of lading, so send us the inventory when you book rather than turning up with extra pallets on loading day. A container that has to wait while paperwork is amended is an expensive container.
Household goods and personal effects are a separate category with their own treatment at many destinations, so tell us if you intend to send any rather than packing them in with the parts. Our parts and engines guide covers how that cargo is prepared.
The weight limit, and when it matters
A twenty foot container has a payload limit that is lower than most people assume, and on a car shipment it rarely bites, because a passenger vehicle is lighter than it looks. Where it does bite is when the box is filled with heavy items around the car: engines, transmissions, axles, brake rotors and similar dense cargo will reach the weight limit long before the container runs out of room.
If you are loading a vehicle plus a significant quantity of heavy parts, tell us the rough weight when you book. There are also road weight limits on the trucking leg at both ends, and a container that is legal at sea can still be over the limit on the road, which is a problem best discovered before it is packed rather than after.
Machinery and non car cargo
A twenty foot container is not only a car box. Compact machinery frequently goes into one: a small skid steer, a mini excavator under about three tonnes, a compact tractor, or a quantity of implements and attachments. Whether a particular machine fits comes down to its width across the tracks or tires and its height in transport position rather than to its weight.
Heavy parts loads also suit a twenty foot container very well, for the reason given above. A container of engines reaches its weight limit with the box less than full, so paying for a forty foot would be paying for space you cannot legally fill. Our mini excavator guide and skid steer guide cover the machine side in more detail.
20ft container shipping FAQ
How many cars fit in a 20ft container?
One. A twenty foot container is sized for a single vehicle and that is what it does well. The only real exception is a car small enough that two genuinely fit, which in practice means something on the scale of a Smart car. Anything appreciably larger takes the box on its own, whatever anyone claims.
Can two small cars fit in a 20ft container?
Only if they are very small indeed, on the scale of a Smart car. Two of those will go in. Two ordinary small hatchbacks will not, and a quote built on the idea that they will is a quote that changes at the warehouse. Send us the models and we will measure them against the box rather than estimate.
Is a 40ft high cube better for two cars?
Yes, almost always, and it is usually cheaper per vehicle than two twenty foot containers would be. A forty foot high cube takes two ordinary cars comfortably and more with disassembly. If you are moving two or more vehicles, that is the box to be looking at rather than trying to force a twenty foot.
Can I put a car and a motorcycle in a 20ft container?
In many cases yes, since a motorcycle takes up far less room than a second car and fits in space that would otherwise be wasted. It has to be secured properly so that nothing can move against the vehicle, and it has to appear on the export filing and the bill of lading. Tell us when you book and we will confirm it against your particular car.
Is a 20ft container cheaper than a 40ft?
For a single vehicle, usually yes. The ocean freight on the smaller box is lower on most lanes and you are not paying for space you cannot use. The gap is smaller than people expect, though, and the moment a second vehicle or a quantity of parts comes into it, the forty foot high cube usually wins on cost per item.
When should I pay for the bigger container instead?
When you have more to send than one car. A second vehicle, a motorcycle, a pallet of spares or a significant parts load all tip the comparison, because the cost difference between the boxes is modest while the usable space difference is large. Tell us everything you might send before you book rather than only what you have already decided on.
How much does it cost to ship a car in a 20ft container?
It depends on where the vehicle is collected in the United States, the destination port, the sailing frequency on that lane and what else is in the box. Because we are the ocean carrier of record rather than a broker reselling space, the figure you get is the real one. Send us the car and the destination and we will price it.
Is a 20ft container easier to get than a 40ft?
On some lanes, yes. Equipment availability moves around, and there are routes and weeks where twenty foot containers are easier to come by than forty foot high cubes, which can mean an earlier sailing. We check what is actually available on your route when we quote rather than assuming either way.
Will a pickup truck fit in a 20ft container?
It depends on the truck, and height is what decides it rather than length. A smaller pickup often will, while a full size crew cab frequently will not without work. Deflating the suspension, removing roof fittings and letting the tires down can gain the inches needed on some models. Send us the year, make and model and we will check the figures.
Will an SUV fit in a 20ft container?
A small or mid size crossover usually will. A large full size sport utility vehicle often will not without lowering it, and some will not at all. The difference between a model that fits and one that does not is frequently only an inch or two, which is exactly why it needs checking against the specific vehicle rather than the class.
What is the internal height of a 20ft container?
A little under eight feet inside, with the door opening lower than the internal height, and it is the door opening that usually decides whether a vehicle goes in. You can see the full internal dimensions on our shipping tools page. For a tall vehicle, a forty foot high cube gives you the extra height and removes the question.
Can you lower a vehicle to make it fit?
We do it regularly. Deflating the suspension, letting the tires down and removing roof racks, light bars or aerials can gain the clearance needed on a vehicle that is close to the limit. It is normal work rather than a last resort. What we will not do is tell you a vehicle fits when the figures say it does not.
Can I ship parts in the same container as my car?
Yes, and there is genuine usable space in front of, behind and alongside a vehicle. Spare parts, wheels, tires, boxed items and tools all travel well there and add very little to the freight. Everything has to be declared before the container is sealed, so send us the inventory when you book rather than on loading day.
Can I ship personal effects with the car?
Household goods and personal effects are declared differently from vehicles and parts, and several destinations apply their own rules to them. They are not simply filler for the leftover space. Tell us if you want to send any so that it is handled correctly from the start, because packing them in quietly is how shipments get held.
Do I have to list everything in the container?
Yes, every item appears on the United States export filing and on the bill of lading. A pallet that turns up unannounced on loading day holds up the whole booking while the paperwork is amended, and a container waiting at a port is an expensive container. Sending the full inventory at booking takes a few minutes and avoids all of it.
What is the weight limit on a 20ft container?
It is lower than most people assume, though on a car shipment it rarely matters because a passenger vehicle weighs less than it looks. Where it does matter is when the box is filled with dense cargo around the car, since engines, transmissions and axles reach the limit long before the container runs out of room. Tell us the rough weight if you are loading heavy items.
Can a 20ft container be too heavy for the road?
Yes, and it is worth knowing. There are road weight limits on the trucking leg at both ends, and a container that is perfectly legal at sea can still be over the limit on the road. It is a problem far better discovered before the box is packed than after, so give us the weights when you book a heavy load.
Is a 20ft better for heavy parts than a 40ft?
Often yes, for exactly that reason. A load of engines or similar dense cargo reaches the weight limit with the box less than full, so a forty foot would be space you are paying for but cannot legally fill. For heavy, compact cargo the smaller container is frequently the more economical choice.
Can machinery go in a 20ft container?
Yes, and it is a common use for the box. A small skid steer, a mini excavator under about three tonnes, a compact tractor or a quantity of implements and attachments all fit regularly. What decides it is the width across the tracks or tires and the height in transport position rather than the weight.
Will a mini excavator fit in a 20ft container?
A smaller machine under about three tonnes frequently will, and that can be the cheaper booking for a single unit. The deciding numbers are the transport height with the boom folded and the width across the tracks. We check the specific model, because dimensions change between model years more often than buyers expect.
How do I work out whether my cargo fits?
Send us the dimensions and we will check them against the box, or use the CBM calculator on our shipping tools page to work out your volume first. For vehicles the model number alone is usually enough for us to look up the rest. We would far rather check it properly at the quote stage than discover it at the warehouse.
How fast can you quote?
Within 24 to 48 hours in normal cases. We need the vehicle or cargo details, the collection location in the United States, the destination port and a list of anything travelling alongside. Send those over and we will tell you which box is cheaper for your shipment.
