Quick Answer: A standard 40ft shipping container holds the contents of a typical three to four bedroom home, roughly 2,390 cubic feet, or about 20 to 21 standard pallets floor-loaded. A 20ft holds a two to three bedroom load, near 1,170 cubic feet and 10 pallets. Payload caps both well before the space runs out.

How much fits inside a shipping container?
A 40ft shipping container holds about 2,390 cubic feet of usable space, which absorbs the furniture and boxed belongings of a three to four bedroom house, or roughly 20 to 21 standard pallets set on the floor in a single layer. A 20ft container holds close to 1,170 cubic feet, enough for a two to three bedroom load or about 10 standard pallets. Those are the two numbers most buyers actually need, and the rest of this page shows where they come from and where the real-world catches are.
Capacity sounds like a simple question and it is not, because there are two separate ceilings on every container. The first is volume, the cubic space inside the steel. The second is payload, the maximum weight the box is rated to carry. For anything dense, like flooring, tile, machinery, feed, or packed records, you hit the weight ceiling long before you run out of floor. For light, bulky goods, like furniture and seasonal storage, you fill the space first. Knowing which ceiling you are about to hit is the whole game, and it is the piece most online capacity charts leave out.
We sell and deliver these boxes across Ontario from our Brantford yards, and the capacity question lands at the yard every week. So this is the honest version, built on the ISO 668 and ISO 6346 internal figures, not a rounded-off marketing graphic.
Why we get this question at the Brantford yard
Van Blanc Ent. Inc. is a family-run shipping container yard in Brantford, Ontario, in business since 1995. We sell new and used sea cans, build modifications, and deliver across Ontario in 1 to 3 days from our four yards on a cash-on-delivery basis. Buyers come in trying to size the box to the load, a barn’s worth of equipment, a shop’s overflow inventory, a household stored for a year, and the right answer is always the smallest box that clears both the space and the weight you actually have. Walk the yard with us and you can stand inside both sizes before you decide.
What are the real internal dimensions and cubic capacity?
The usable space inside a container is smaller than the external badge size, because the corrugated steel walls, corner castings, and floor structure all eat into it. A 20ft container measures 20 feet on the outside but gives you about 19 feet 4 inches of internal length. A 40ft gives you about 39 feet 5 inches inside its 40 foot shell. Those inches matter when you are fitting pallets end to end, which is exactly why pallet math is tighter than people expect. Here are the figures that come straight from the ISO 668 dimensional standard, in both Imperial and metric.
| Spec | 20ft Standard | 40ft Standard | 40ft High Cube |
|---|---|---|---|
| Internal length | 19 ft 4 in (5.90 m) | 39 ft 5 in (12.03 m) | 39 ft 5 in (12.03 m) |
| Internal width | 7 ft 8 in (2.35 m) | 7 ft 8 in (2.35 m) | 7 ft 8 in (2.35 m) |
| Internal height | 7 ft 10 in (2.39 m) | 7 ft 10 in (2.39 m) | 8 ft 10 in (2.70 m) |
| Door opening width | 7 ft 8 in (2.34 m) | 7 ft 8 in (2.34 m) | 7 ft 8 in (2.34 m) |
| Internal volume | 1,170 cu ft (33 m³) | 2,390 cu ft (67.7 m³) | 2,694 cu ft (76.4 m³) |
| Max payload | 62,000 lb (28,200 kg) | 59,000 lb (26,800 kg) | 63,000 lb (28,560 kg) |
| Floor area | 146 sq ft (13.6 m²) | 300 sq ft (27.9 m²) | 300 sq ft (27.9 m²) |
The High Cube line is the one people overlook. A 40ft High Cube is the same length and width as a standard 40ft, but it stands a foot taller, which adds about 300 cubic feet of pure overhead volume. For light, stackable storage, that extra foot is the cheapest cubic capacity you can buy, because you pay for footprint and ground space once and gain a whole layer above your head. If your goods stack and your driveway can take the height, the High Cube is usually the smarter cube. For full specs on each, compare the seven sizes on our container options page or read the deeper container sizes and dimensions guide.
How many pallets fit in a 20ft or 40ft container?
A 20ft container fits 10 standard pallets floor-loaded in a single layer, and a 40ft container fits 20 to 21, using the standard North American 48 by 40 inch GMA pallet. The internal width of 7 feet 8 inches will not quite take two 48-inch pallets side by side turned the same way, so loaders alternate orientation, one pallet long-side-in beside one short-side-in, to claw back the floor. That alternation is why the real count lands where it does instead of a clean round number.
| Pallet type | 20ft, single layer | 40ft, single layer | 40ft, double-stacked |
|---|---|---|---|
| Standard GMA (48 x 40 in) | 10 pallets | 20 to 21 pallets | up to 40 to 42 (if light) |
| Euro pallet (1200 x 800 mm) | 11 pallets | 23 to 25 pallets | up to 46 to 50 (if light) |
| Industrial (1200 x 1000 mm) | 9 to 10 pallets | 20 to 21 pallets | up to 40 to 42 (if light) |
Double-stacking is where the headline numbers come from, and where the honesty has to come in. Yes, a 40ft can theoretically take up to 40-plus standard pallets in two tiers, but only if the loaded weight stays under the payload rating and the stacked height clears the ceiling. Stack two layers of anything dense and you will blow the weight limit long before the second tier is full. So treat the double-stacked column as a height-and-weight-permitting ceiling, not a promise. The single-layer count is the number you can actually plan around for most goods.
The pallet trap that bites first-time loaders
Pallets do not fill a container to the wall. With 48-inch pallets in a 7-foot-8 box, you are left with a strip of dead space down one side after alternating orientation. That gap is normal and unavoidable with standard skids. The fix is not a bigger container, it is loose-loading the gap with boxes, or switching to a pallet footprint that nests tighter to your width. If your whole operation runs on Euro pallets, a container actually carries more of them than the North American count suggests.
How much furniture can fit in a 40 foot container?
A 40 foot container fits the furniture and packed belongings of a typical three to four bedroom home, and a 20ft holds a two to three bedroom load. The working rule of thumb, used across the storage industry, is that each furnished room takes up roughly 150 cubic feet once its furniture and boxes are packed. Run that against the cubic capacity and the room counts fall out cleanly: a 20ft at 1,170 cubic feet covers about seven to eight rooms of contents, a 40ft at 2,390 covers fourteen to sixteen, which is why the bedroom shorthand works.
To put real objects in the box, a well-packed 40ft container comfortably absorbs something on the order of three sofas, four bed sets, a couple of dining suites, major appliances, and a wall of boxes, with room left over. A 20ft swallows the heart of a smaller household, the beds, the couches, the fridge and washer, the seasonal bins, with the boxes filling the gaps between the big pieces. These are storage capacities, the volume of the box you own and load yourself or have loaded. Van Blanc supplies and delivers the container; we are not a moving company and we do not pack or haul your belongings.
Household stored for a year: which box won
A common yard scenario: a family selling and rebuilding needs their whole house held for about a year while construction runs. A three-bedroom worth of furniture and boxes lands right around the 40ft line. The deciding factor is rarely the furniture itself, it is the awkward tall pieces, the armoire, the fridge, the standing mirror. On a standard 40ft those clear with inches to spare. The moment someone has a tall china cabinet or wants a clean walkway down the middle to reach things during the year, the 40ft High Cube and its extra foot of height earns its keep.
The single biggest variable is packing quality. A poorly packed container holds far less than a tightly packed one, on the order of 30 percent less usable load, because air between loose pieces is wasted cubic capacity. Disassemble bed frames and tables, stand mattresses and sofas on end against the walls, fill drawers and appliances with soft goods, and build a solid wall of uniform boxes. The difference between a careful load and a careless one is often a whole size of container.
Christian LeBlanc, second-generation operator: “People size by the floor plan and forget the box has a weight rating. I had a buyer last spring sure he needed a 40ft for a load of patio stone and tile. Volume-wise, half a 20ft. But by weight that tile would have buried the payload limit on either box. We split it across two drops instead. The container is rated to the pound, not just the cubic foot, and that is the number that actually stops you.”
Why is weight the limit that catches people?
Weight stops a load before space does whenever the cargo is dense, and that surprises people who size purely by cubic feet. Every container carries a maximum payload, the weight of cargo it is rated to hold on top of its own empty tare weight. A 20ft is rated near 28,200 kilograms of payload and a 40ft near 26,800, with the combined gross weight capped at 30,480 kilograms under the ISO standard. Those are large numbers for furniture and light storage, which is why a household load never threatens them. They are small numbers for stone, tile, brick, steel, packed paper, or wet feed, which is why dense loads hit the wall fast.
The arithmetic is unforgiving. A 40ft holds 2,390 cubic feet, but if you filled all of it with something that weighs even 30 pounds per cubic foot, you would be carrying over 70,000 pounds, well past the payload rating and past what any road-legal axle setup can move. So dense cargo is always a weight calculation first and a space calculation second. The practical signal is simple: if you can lift a sample of your goods easily, you will fill the space first and should size by volume. If a single box of it is a two-person job, you will hit weight first and should size by payload, and often split the load across more than one container.
Space-limited or weight-limited? A quick read
- Size by VOLUME (you fill the space first): furniture, household goods, seasonal storage, retail stock, packaging, light equipment, anything you can carry by hand.
- Size by PAYLOAD (you hit the weight first): tile, flooring, stone, brick, concrete products, steel, machinery, packed records and paper, bagged or wet feed, automotive parts.
- The split-load signal: if a dense load pencils out over the payload rating, two containers or two drops is safer and road-legal, not one overloaded box.
- The High Cube bonus: for light, stackable goods, the extra foot of height on a 40ft High Cube is the cheapest cubic capacity available, because the footprint cost is the same.
Which size do you actually need?
The right container is the smallest one that clears both your volume and your weight with a little margin, and for most Ontario buyers that decision comes down to three honest questions. How much do you have, measured in rooms or pallets? How dense is it, hand-carry light or two-person heavy? And do you need height, because tall pieces or a center walkway change the answer toward a High Cube. Get those three straight and the size picks itself.
For storage that lives on your property long term, owning the box beats renting space the moment your timeline runs past a couple of years, and a container you own can be modified, shelved, vented, or wired to fit the goods exactly. A 20ft Cargo Worthy suits a trade or a household overflow that fits a two to three bedroom volume. A 40ft High Cube suits a full household hold, a growing business inventory, or any load where the extra cubic capacity overhead pays off. Whatever the load, the way to be certain is to stand inside both at the yard.

Frequently Asked Questions
How much furniture can fit in a 40 foot container?
A 40 foot container holds the furniture and packed belongings of a typical three to four bedroom home, roughly 2,390 cubic feet of usable space. Using the industry rule that each furnished room fills about 150 cubic feet, that covers fourteen to sixteen rooms of contents. A well-packed 40ft comfortably absorbs around three sofas, four bed sets, a couple of dining suites, major appliances, and a wall of boxes with room to spare.
How many pallets fit in a 20ft and a 40ft container?
A 20ft container fits 10 standard 48 by 40 inch pallets floor-loaded in a single layer, and a 40ft fits 20 to 21. Loaders alternate pallet orientation because two 48-inch pallets will not sit side by side in the 7-foot-8 internal width. If the cargo is light enough to double-stack and clear the ceiling and payload limit, a 40ft can theoretically take up to 40 to 42 pallets, but weight usually stops you before the second tier fills.
What is the internal cubic capacity of a shipping container?
A standard 20ft container has about 1,170 cubic feet (33 cubic metres) of internal volume, a standard 40ft has about 2,390 cubic feet (67.7 cubic metres), and a 40ft High Cube has about 2,694 cubic feet (76.4 cubic metres). The High Cube gains roughly 300 cubic feet purely from standing one foot taller, with the same length and width as a standard 40ft.
How much weight can a shipping container hold?
A 20ft container carries a maximum payload near 28,200 kilograms and a 40ft near 26,800 kilograms, with the combined gross weight, container plus cargo, capped at 30,480 kilograms under the ISO standard. Those limits are generous for furniture and light storage but tight for dense goods like tile, stone, or steel, which hit the weight ceiling long before the space is full. Dense loads should be sized by weight, not cubic feet.
Will a 20ft or 40ft container fit a two or three bedroom home?
A 20ft container holds the contents of a two to three bedroom home, including beds, couches, appliances, and seasonal storage, at about 1,170 cubic feet. A 40ft holds a three to four bedroom load at about 2,390 cubic feet. Packing quality is the biggest variable: a poorly packed box holds around 30 percent less than a tightly packed one, so disassembling furniture and building a solid box wall can save you a whole size.
Can I see both container sizes before I buy from Van Blanc?
Yes. You can drive to our Brantford yard at 90 Morton Avenue East, stand inside both a 20ft and a 40ft, and pick the exact box before you pay a dollar. Bring your rough room or pallet count and we will tell you which size clears both your volume and your weight.
