Shipping Container Sizes Explained: Which Size Do You Need to Move Abroad?

When you’re moving everything you own abroad, the container you choose affects both cost and convenience. Book one that’s too large and you may pay to ship empty space, but book one that’s too small and you may need to leave items behind, reduce your shipment, or arrange a second consignment that removes any saving.

Choosing the right size is easier once you understand how container capacity works. The right fit depends less on the number of rooms in your home and more on the total volume of your belongings, so careful estimating matters before a booking is made.

Simpsons has over 35 years of experience helping customers move worldwide and across Europe, with international removals services covering household moves, smaller luggage consignments, container shipping, packing, and destination planning. That experience matters here because container size is not just a technical detail. It affects quote accuracy, loading plans, transit costs, and whether your belongings travel in one well-planned shipment.

What Are the Standard Shipping Container Sizes?

Two container sizes cover the majority of household moves: the 20ft and the 40ft, with a taller variant called the 40ft High Cube for bulky loads. The table below gives the dimensions, usable volume, and payload for all three.

Specification	20ft Standard	40ft Standard	40ft High Cube (HC)
External length	6.06 m (20 ft)	12.19 m (40 ft)	12.19 m (40 ft)
External width	2.44 m (8 ft)	2.44 m (8 ft)	2.44 m (8 ft)
External height	2.59 m (8 ft 6 in)	2.59 m (8 ft 6 in)	2.90 m (9 ft 6 in)
Internal length	5.90 m	12.03 m	12.03 m
Internal width	2.35 m	2.35 m	2.35 m
Internal height	2.39 m	2.39 m	2.70 m
Door opening width	2.34 m	2.34 m	2.34 m
Door opening height	2.28 m	2.28 m	2.58 m
Usable internal volume	Approx. 33 cubic metres	Approx. 67 cubic metres	Approx. 76 cubic metres
Maximum payload	Approx. 28,000 kg	Approx. 26,500 kg	Approx. 26,500 kg
Typical household match	1 to 2-bed home	3 to 4-bed house	4+ bed house or extra-bulky items

These figures are the industry standard for ISO containers and can vary slightly between manufacturers, so treat them as reliable rather than absolute. The usable volume is always less than the theoretical volume, because furniture does not stack into a neat cube and packing around awkward shapes leaves gaps. 

The High Cube shares the standard 40ft footprint but adds roughly 30cm of internal height, which helps with tall items or with maximising volume on the same shipping slot.

What Shipping Container Size Do I Need to Move My House Overseas?

The size you need is determined by the volume of your belongings rather than the number of rooms, though the room count provides a starting point. The table below matches household sizes to container options. Two homes with the same number of bedrooms can hold very different amounts, so the matches below are a guide rather than a fixed rule.

Household Size	Typical Volume	Recommended Option	What It Typically Includes	Notes
Studio / 1-bed flat (minimal furniture)	8 to 15 cubic metres	Shared container (LCL)	Bed, sofa, wardrobe, boxes, small appliances	Rarely worth a full 20ft; share to save money
1 to 2-bed flat or small house	15 to 30 cubic metres	20ft container or large LCL share	Full bedroom and living room furniture, white goods, boxes	20ft if close to filling it; otherwise share
2 to 3-bed house	30 to 50 cubic metres	20ft (if minimal) or 40ft (if full)	Multiple bedrooms, lounge, dining, kitchen, garage items	The most common borderline decision; survey essential
3 to 4-bed house	50 to 67 cubic metres	40ft container	Full house contents including garden and garage	Standard choice for established family homes
4+ bed house or large volume	67+ cubic metres	40ft High Cube or multiple containers	Full house plus bulky/specialist items	May need 40ft HC or a second container

Room count is only a rough guide, which is where sizing often goes wrong. Two three-bedroom houses can differ by a whole container’s worth of volume depending on how much each family owns, so a professional volume survey is the only reliable method. Simpsons provides that survey free and without obligation, because getting the size right at the planning stage costs far less than discovering the mistake at the port.

How Much Furniture Fits in a 20ft Versus a 40ft Container?

Seeing what each container typically holds makes it easier to compare your own move. A 40ft container gives roughly double the usable space of a 20ft container, but the final fit depends on furniture shape, box count, and how efficiently the load can be packed. 

What Fits in a 20ft Container?

A 20ft container holds roughly the contents of a one to two-bedroom home, which in practice tends to look like this:

• One or two bedroom sets, comprising beds, wardrobes and drawers.
• A three-piece lounge suite.
• A dining table and chairs.
• A fridge-freezer and a washing machine.
• A small number of additional appliances.
• Somewhere between 50 and 100 packing boxes.

What Fits in a 40ft Container?

A 40ft container holds roughly double that, about the contents of a three to four-bedroom house:

• Three to four full bedroom sets.
• A large lounge suite and dining furniture.
• Full kitchen contents and white goods.
• Garden furniture along with garage and shed items.
• Bicycles and larger outdoor equipment.
• Somewhere between 100 and 200 packing boxes.

The comparison below draws out what each size means for cost and risk, not just capacity.

Factor	20ft Container	40ft Container	Practical Implication
Usable volume	Approx. 33 cubic metres	Approx. 67 cubic metres	40ft holds roughly double
Bedrooms it suits	1 to 2	3 to 4	Match to actual volume, not just rooms
Approx. boxes (medium)	50 to 100	100 to 200	Depends heavily on furniture-to-box ratio
Cost difference	Lower base cost	Higher, but better cost per cubic metre	40ft is cheaper per unit of space if you fill it
Best for	Smaller homes, downsizers, couples	Family homes, full relocations	Avoid paying for empty space
Risk if undersized	Items left behind, costly second shipment	N/A	A survey prevents this
Risk if oversized	Paying for unused space, items shifting in transit	Paying for unused space	Shared container avoids this for smaller loads

A 40ft container costs more in absolute terms but works out cheaper per cubic metre if you can fill it, so the wrong choice wastes money in either direction, through empty space you have paid for or a second shipment you did not budget for.

Should I Use a Shared Container or a Full Container for Moving Abroad?

This is one of the biggest cost decisions in the move, and it turns almost entirely on volume. Below roughly 25 to 30 cubic metres, sharing a container is usually cheaper; above it, hiring a whole container tends to give both better value and faster transit. Both approaches are explained below.

Full Container Load (FCL) Explained

With a Full Container Load you hire an entire container exclusively for your belongings, and the advantages are speed and security. The container is sealed at origin and opened at destination, it travels on a set schedule, and it passes through fewer hands along the way. FCL makes sense once your volume is above roughly 25 to 30 cubic metres, or whenever you place a high value on security and speed regardless of how much you are shipping.

Shared Container Shipping (LCL / Groupage) Explained

With Less than Container Load shipping, your belongings share container space with other consignments heading to the same destination, and you pay only for the space you use, which makes it economical for smaller moves. 

The trade-offs are time and handling: the shipment is consolidated with others before it sails and deconsolidated at the far end, passing through more hands on the way. LCL makes sense when your volume sits below roughly 25 to 30 cubic metres. The comparison below sets the two methods against each other.

Factor	Full Container (FCL)	Shared Container (LCL / Groupage)
How it works	You hire the whole container	You share space and pay per cubic metre
Best for volume	25 to 30+ cubic metres	Under 25 to 30 cubic metres
Cost structure	Flat rate for the container	Pay only for space used
Cost efficiency at small volume	Poor (paying for empty space)	Excellent
Cost efficiency at large volume	Excellent	Poor (per-cubic-metre rate adds up)
Transit time	Faster (direct)	Slower (consolidation and deconsolidation add time)
Security	Higher (sealed at origin, opened at destination)	Slightly lower (more handling, shared space)
Handling touchpoints	Fewer	More
Schedule	Set departure	Waits for container to fill or consolidation date
Typical suitability	3 to 4-bed house moves	1 to 2-bed flats, downsizers, partial moves

The decision comes back to volume. Below roughly 25 to 30 cubic metres, shared is almost always the more economical choice. Above that threshold, a full 20ft or 40ft container usually offers better value and a faster journey, because the per-cubic-metre rate on a shared load mounts while a full container gives a direct, sealed run to the destination.

How Do I Estimate the Volume of My Belongings for International Shipping?

There are two ways to estimate your volume. One is a professional survey, the accurate method, and the other is a do-it-yourself estimate, useful for a first ballpark before anyone visits. Both are covered below, and they work best in that order.

The Professional Volume Survey (Most Accurate Method)

A professional survey, carried out in person or by video call, has a surveyor itemise your belongings and calculate the volume precisely. It is free, quick, and removes the guesswork that leads to sizing errors, which is why Simpsons recommends it at the point of booking. It is the difference between paying for exactly the space you need and finding out about a miscalculation once the container is at the dock.

The DIY Volume Estimation Method

For a rough figure ahead of a survey, you can estimate the volume yourself. List your major furniture items and assign each an approximate cubic metre value, count your packing boxes, add them up, and add a buffer of 10% to 15% for packing inefficiency. The quick-reference values below will get you started.

• Three-seat sofa: approx. 1.5 cubic metres
• Double bed and mattress: approx. 2.3 cubic metres
• Double wardrobe: approx. 1.5 cubic metres
• Chest of drawers: approx. 0.6 cubic metres
• Dining table (seats six): approx. 1.2 cubic metres
• Fridge-freezer: approx. 0.9 cubic metres
• Washing machine: approx. 0.8 cubic metres
• Standard medium packing box: approx. 0.1 cubic metres
• Bicycle: approx. 0.8 cubic metres

A DIY estimate is useful for a ballpark, but confirm it with a professional survey before booking, because under-estimating leaves belongings behind while over-estimating means paying for space you never use. The buffer matters, since belongings rarely pack as tidily as the raw numbers suggest.

How Much Does It Cost to Ship a Container Overseas?

Container shipping costs depend on several variables rather than a fixed price, and any figure quoted in the abstract dates quickly. The factors below are the ones that matter, and knowing them helps you read a quote and see where you can influence it.

• Container size and load type, meaning 20ft versus 40ft versus a shared LCL load.
• Destination and route, since Europe is the cheapest and fastest while Australia, New Zealand and remote destinations cost more.
• Door-to-door versus port-to-port, as a full service including collection, packing, customs and delivery costs more than moving container to container.
• Season and shipping market conditions, because freight rates rise and fall with global demand and fuel costs.
• Customs, duties and port handling, which vary from one destination country to the next.
• Insurance, which is based on the declared value of your goods.
• Access and special requirements, where difficult access, long carries or special items such as pianos and vehicles add cost.

The most reliable way to turn all of that into a firm figure is a personalised quote based on a volume survey, which pins down both the volume and the services included rather than leaving either to estimate.

How Long Does Container Shipping Take Internationally?

Transit times vary considerably by region, and the table below gives indicative sea transit figures from the UK. These cover the sea leg alone, so you will need to add packing time at the UK end and customs clearance and delivery at the destination.

Destination	Approx. Sea Transit Time (FCL)	Add for LCL (Consolidation)	Notes
Western Europe	1 to 2 weeks	1 to 2 weeks	Short routes; road freight sometimes faster
USA East Coast	2 to 4 weeks	1 to 3 weeks	Customs clearance adds days
USA West Coast	4 to 6 weeks	1 to 3 weeks	Longer route via Panama or transhipment
UAE / Middle East	3 to 5 weeks	1 to 3 weeks	Direct routes available
Australia / New Zealand	6 to 12 weeks	2 to 4 weeks	Longest routes; consolidation schedules vary
South Africa	4 to 6 weeks	2 to 3 weeks	Direct and transhipment routes
Far East (Singapore, Hong Kong)	4 to 7 weeks	2 to 3 weeks	Well-served routes

Because these are sea transit estimates only, and exclude packing at origin, customs clearance, and delivery at destination, it is sensible to add a buffer of one to two weeks when you plan around them.

Can You Ship a Car or Special Items in a Container?

Yes, a car can travel in a 40ft container alongside household goods, loaded first and secured while the belongings are packed around or in front of it, behind a bulkhead, subject to the destination country’s import rules. 

The same approach handles other special items, from pianos and artwork to wine collections and garden equipment, each of which may need its own packing or crating. 

Customs and biosecurity are the main considerations, particularly for Australia and New Zealand, which enforce strict cleanliness standards for vehicles and outdoor equipment, so anything that has touched soil needs a thorough clean before packing. With professional handling and the right documentation, a mixed shipment of this kind moves through customs without delay.

Choosing the Right Container Size with Simpsons Removals

Choosing the right container size comes down to volume, not room count alone. A 20ft container holds around 33 cubic metres and is often suited to a one to two-bedroom home, while a 40ft container holds around 67 cubic metres and is more commonly used for a three to four-bedroom house. A 40ft High Cube gives extra height on the same footprint, so it can help when the load includes taller or bulkier items.

Those matches are useful, but they’re still only a guide. Two homes with the same number of rooms can hold very different amounts, especially if one has loft contents, garden furniture, tools, bikes, large wardrobes, or extra boxes in storage. That’s why the most reliable answer comes from measuring the shipment properly before you book.

If your belongings won’t fill a container, shared LCL shipping is often the more economical route. The crossover point is usually around 25 to 30 cubic metres, where a dedicated container can start to make more sense than paying for space in a shared load.

Online estimates are useful for reaching a rough figure, but they shouldn’t be the final basis for the booking. A professional survey helps confirm the actual volume, choose the right container, and avoid the two expensive mistakes this guide is designed to prevent: paying to ship empty space or leaving items behind and arranging a second shipment later.

Simpsons has over 35 years of experience helping thousands of customers move worldwide and within Europe, with survey-led quoting designed to size each move properly. That means your container recommendation is based on the space your belongings actually need, not a loose room-count estimate.

Frequently Asked Questions

What size shipping container do I need to move house?

For a 1 to 2-bedroom home, a 20ft container, offering approximately 33 cubic metres, is usually sufficient. For a 3 to 4-bedroom house, a 40ft container, offering approximately 67 cubic metres, is the standard choice. The most accurate way to decide is a professional volume survey, because the volume of your belongings matters more than the number of rooms.

How much can a 20ft container hold?

A 20ft shipping container holds approximately 33 cubic metres of usable space, equivalent to the contents of a 1 to 2-bedroom home. This typically includes one or two bedroom sets, a lounge suite, dining furniture, white goods and 50 to 100 packing boxes. Actual capacity depends on furniture shapes and packing efficiency.

What is the difference between a 20ft and 40ft container?

A 40ft container is twice the length of a 20ft container and holds roughly double the volume, approximately 67 cubic metres versus 33 cubic metres. Both share the same width and standard height. A 20ft container suits a 1 to 2-bed home, while a 40ft container suits a 3 to 4-bed house. The 40ft offers a better cost per cubic metre when filled.

Is it cheaper to share a container when moving abroad?

Yes, for smaller volumes. Shared container shipping, known as LCL or groupage, lets you pay only for the space your belongings occupy, making it more economical for volumes below approximately 25 to 30 cubic metres. For larger volumes, a full container usually offers better value per cubic metre and faster transit because it avoids consolidation delays.

How do I work out the volume of my belongings?

List your major furniture items and assign approximate cubic metre values, for example a sofa at around 1.5 cubic metres and a double bed at around 2.3 cubic metres, count your packing boxes at around 0.1 cubic metres each, then sum the total and add a 10% to 15% buffer. For accuracy, book a free professional volume survey before confirming your container size.

What are standard shipping container dimensions?

A standard 20ft container has internal dimensions of approximately 5.90m long, 2.35m wide and 2.39m high, giving around 33 cubic metres of usable space. A standard 40ft container is approximately 12.03m long with the same width and height, giving around 67 cubic metres. The 40ft High Cube adds roughly 30cm of internal height.

How long does container shipping take internationally?

Sea freight from the UK takes approximately 1 to 2 weeks to Western Europe, 2 to 6 weeks to the USA depending on coast, 3 to 5 weeks to the Middle East, and 6 to 12 weeks to Australia and New Zealand. Shared container shipping adds 1 to 4 weeks for consolidation. Add a buffer for customs clearance and final delivery.

Can I put a car in a shipping container with furniture?

Yes, a car can be shipped in a 40ft container alongside household goods, with the vehicle loaded first and belongings secured around it. However, destination import rules vary, and countries such as Australia and New Zealand enforce strict biosecurity cleanliness standards for vehicles. Professional handling and correct documentation are essential to avoid customs delays.
