How Much Can You Fit in a 20ft Storage Container?

What are the dimensions of a 20ft storage container?

A standard 20ft shipping container measures 20ft long by 8ft wide by 8ft 6in high on the outside, following the ISO dimensions used across the shipping and storage industry. Converted or purpose-built storage containers, like the ones used for self storage, are usually described as 20ft x 8ft x 8ft for simplicity, though actual internal space is slightly less once you allow for the steel walls, floor and roof structure.

Internally, you can expect a usable space of approximately 5.9 metres long, 2.35 metres wide and 2.39 metres high. That works out at around 33 cubic metres, or roughly 1,170 cubic feet, of storage volume. The door opening at the end is typically close to the full width and height of the container, which makes it straightforward to walk furniture straight in rather than having to manoeuvre it through a narrow hatch.

Because the walls and roof are solid steel, a container is a fully enclosed, weatherproof space from floor to ceiling, which means you can genuinely use the full height for stacking boxes and furniture, rather than losing capacity to sloped roofs or low beams as you might in a loft or some indoor storage rooms.

Which size home fits into a 20ft container?

The amount of furniture a household owns varies enormously, but removal industry guidance and self storage operators generally agree on a rough rule of thumb that links container size to the number of bedrooms in a home. A 20ft container sits comfortably in the middle of the typical range, suitable for most 2 to 3 bedroom households, and often stretching to a small 4 bedroom home if you are reasonably organised with packing.

These figures are approximate, because two three bedroom households can have very different amounts of furniture depending on how long they have lived there, whether they have a garage full of tools, or children's bedrooms packed with bulky items. If in doubt, it is always worth erring on the side of a little extra space, or asking a storage provider for advice based on what you actually own.

For customers near York, a single 20ft container is often the sensible starting point for a house move, a renovation, or decluttering before selling, since it covers the contents of most typical family homes in the area without paying for space you will not use.

What furniture and items fit in a 20ft container?

To make the numbers above more concrete, here is a practical look at what a 20ft container can typically hold for households of different sizes. These are general examples based on average-sized furniture, and your own items may be larger or smaller.

1 bedroom flat

• A double bed, mattress and bedside tables
• A small sofa or two-seater and a coffee table
• A wardrobe or chest of drawers
• A small dining table with two chairs
• A fridge-freezer, washing machine and a handful of boxes

2 bedroom house or flat

• Two bedrooms of beds, mattresses and wardrobes
• A three-seater sofa and armchair
• A dining table with four chairs
• Kitchen appliances including a fridge-freezer, washing machine and microwave
• A television, bookshelves and around 50 to 70 standard boxes

3 bedroom house

• Three bedrooms of beds, mattresses, wardrobes and chests of drawers
• A full living room suite, including sofa, armchair, coffee table and TV unit
• A dining table with six chairs
• Kitchen white goods and a washing machine or tumble dryer
• Garden furniture, a lawnmower, and 70 to 90 boxes

4 bedroom house

• Four bedrooms worth of beds, wardrobes and drawers
• A larger living room suite plus a second TV or home office setup
• A dining set for six to eight people
• Multiple white goods, bikes and garden equipment
• Upwards of 90 to 110 boxes, which may mean a second container is worth considering

How many boxes fit in a 20ft container?

Box counts are one of the most useful ways to estimate storage needs, since most house removals are measured in standard-sized boxes. A typical standard moving box measures around 45cm x 45cm x 45cm, giving a volume of roughly 0.09 cubic metres. A larger box, often used for bedding and lighter bulky items, might measure 55cm x 45cm x 45cm, or about 0.11 cubic metres.

Working from the approximate 33 cubic metres of usable space in a 20ft container, and allowing for the fact that boxes never stack with perfect efficiency, plus space needed for furniture and walking access, a realistic estimate is that a 20ft container filled mostly with standard boxes could hold somewhere in the region of 200 to 250 boxes if that were the only thing being stored.

In practice, most households store a mix of furniture and boxes rather than boxes alone, which is why the more useful figure for a typical 2 to 3 bedroom home move is around 50 to 90 boxes, alongside the furniture and appliances listed in the previous section. As a working method, you can estimate your own box count by multiplying the number of boxes per room, typically 15 to 25 for an average bedroom and a similar number for a kitchen or living room, and adding furniture separately.

These figures are approximate and intended as planning guidance rather than an exact calculation, since real households rarely pack a container with boxes alone, and box dimensions vary between suppliers.

How big is a 20ft container compared to a garage or van?

Numbers on a page can be difficult to picture, so it often helps to compare a 20ft container with everyday spaces you already know. A single domestic garage in the UK is typically around 2.4 to 3 metres wide and 5.5 to 6 metres long, which is a very similar footprint to a 20ft container. The key difference is height and usability: a container's straight steel walls and solid roof mean you get the full 2.39 metres of height to work with from front to back, whereas a garage often loses usable space to a sloped roof, roller door mechanism, or items such as a boiler or shelving already fixed to the walls.

A transit van, by comparison, is considerably smaller. A long-wheelbase high-roof transit typically offers around 10 to 13 cubic metres of load space, meaning a 20ft container holds roughly two and a half to three transit van loads. This is a useful comparison if you are planning a house move and trying to work out how many van trips it would take versus hiring a single container.

Seeing the three spaces side by side like this makes it easier to judge whether a 20ft container suits your needs, or whether a smaller or larger container would be a better match. If you are still unsure after comparing sizes, it is always worth speaking to a storage provider who can talk through your specific list of items.

What should you avoid storing in a 20ft container?

While a 20ft container is a versatile space for furniture, boxes, tools, stock and equipment, there are some items that are not suitable for container storage, either for safety reasons or because the environment is not ideal for them.

• Flammable liquids, gas canisters or other hazardous materials
• Perishable food items, which can attract pests
• Live plants or animals
• Items that are highly sensitive to temperature or humidity changes, such as some musical instruments or fine art, unless specifically suited to the storage environment
• Illegal items or anything that cannot legally be kept or transported

For general household and business items, including furniture, electrical goods, books, tools and stock, a well-maintained container is a practical option. At York Storage, the drive-up containers are vented and fitted with insulated roofs, which is designed to help reduce the build-up of condensation compared to a standard unvented container, making them a sensible choice for furniture and fabric items as well as more robust goods.

How can you maximise space in a 20ft container?

Getting the most out of a 20ft container is mostly about planning the load before you start rather than simply carrying items in as they come to hand. A little preparation can be the difference between comfortably fitting a 3 bedroom house and running out of room halfway through.

• Disassemble large furniture such as bed frames, tables and flat-pack wardrobes to reduce their footprint
• Load heavy and bulky items first, placing them along the back and sides to create a stable base
• Use the full height of the container by stacking boxes safely to near the roofline, heaviest at the bottom
• Fill gaps and voids inside wardrobes, drawers and appliances with smaller items, towels or bedding
• Keep a clear central aisle if you expect to need access to items before fully clearing the container
• Label boxes clearly by room so unloading is faster if you need something back out quickly
• Protect upholstered furniture and mattresses with covers to keep them clean during loading

What does a 20ft container cost and how does access work?

Pricing for container storage varies between providers and regions, so it is always worth checking current rates directly. At York Storage, based at The Old Station Works, Station Lane, Shipton by Beningbrough, York YO30 1BS, drive-up 20ft x 8ft x 8ft containers are available from £140 per month, with a 2 month minimum term.

Because the containers are drive-up, you can park your vehicle or van directly alongside the door, which makes loading and unloading furniture far easier than carrying items through corridors or up stairs, as can be the case with some indoor storage facilities. Access is available 24 hours a day, seven days a week, so you are not restricted to limited opening hours if you need to collect or drop off items outside of normal working hours.

For questions on deposits, insurance options or any current offers, it is best to ask us directly, as these details can change and are not something we would want to misstate here.

York Storage also offers commercial yard space from £250 per month, subject to permitted use, which may suit trades or businesses who need a container alongside outdoor space for vehicles, plant or materials.
