Start with footprint, not cube (where will it sit?)

Most buyers come to the yard with a cube number in their head. They know roughly how much stuff they have. The first thing we ask is the opposite question: where are you putting it, and how much flat ground can the truck reach? Cube comes second, because if your driveway is 22 feet long, the 40ft is already off the list no matter how much you have to store.

Here is the footprint reality for each Canadian container size when you account for the container itself plus the access space the tilt-deck truck needs to land it.

The straight-approach number is what catches first-time buyers. The tilt-deck truck has to tilt the bed back almost to vertical to slide the container off. If your driveway curves, if the gate post is in the way, if there is a tree branch hanging at 14 feet, the driver might not be able to place the container where you want it. Christian has walked away from more than one delivery because the customer measured the slab but did not measure the approach.

The other footprint factor is what is under the container. A 20ft fully loaded weighs about 4,500 to 6,000 kg. A 40ft fully loaded can hit 30,000 kg of gross weight. Asphalt cracks, interlock shifts, soft soil deforms. ISO 6346 specifies that the entire container rests on its four corner castings, so all that weight comes down on four points the size of dinner plates. Compacted gravel works. Concrete pads work. Grass works if the soil is firm and dry. Soft spring soil after thaw is a problem.

So before we even talk cube, the footprint conversation goes: how long is the pad, how long is the approach, what is the surface, and how level is it. The cube question gets answered after that.

10ft container: when it’s the right call (and when it isn’t)

The 10ft is the smallest size in our standard fleet. External length 9’10”, internal length 9’3″, roughly 560 cubic feet of capacity. That is about the contents of a one-bedroom apartment or a tidy single-car garage. Used 10ft containers in Canada, with one-trip units pushing. Rental rates start around per month.

The 10ft is the right call in three specific situations.

Tight residential driveways. A buyer in an older Hamilton or Brantford neighbourhood with a 25-foot driveway and a gate post can land a 10ft where a 20ft would not fit. Same for downtown Toronto and the GTA core where placement constraints kill the bigger sizes.

Document or tool storage. A small contractor needs lockable steel storage for hand tools, a few power tools, and a desk’s worth of files. A 10ft holds it with room to spare and costs roughly 60 percent of a 20ft to buy outright.

Pop-up retail and event use. Garden centres, ski-hill rental kiosks, fair-ground concessions. The 10ft is small enough to tuck into a corner of a parking lot and big enough to lock up overnight.

The 10ft is the wrong call when you have any meaningful volume of household goods, any serious construction materials, or you are reasonably sure you will need more space within the year. The cube limitation is severe. You will outgrow it fast.

One thing buyers do not always realise: 10ft containers are not ISO standard intermodal containers. They are not built to the same 20ft or 40ft ISO 668 dimensions and they are not used on ocean shipping routes. Most 10ft containers in the Canadian market are purpose-built or cut down from 20ft units. That matters because resale value is lower (smaller secondary market) and stacking strength is sometimes less than a full ISO 20ft. For storage on the ground, both are fine. For stacking two-high in a yard or moving between sites frequently, the 20ft is more durable per dollar.

20ft container: the default workhorse for most Ontario buyers

If you do not have a strong reason to pick another size, pick a 20ft. The 20ft is the most-built, most-traded, most-resold container in the world and the default answer for the majority of Canadian buyers. External dimensions 20’0″ by 8’0″ by 8’6″ (standard) or 9’6″ (high cube). Internal capacity about 1,170 cubic feet standard or 1,360 cubic feet high cube. Used 20ft pricing in Ontario for Wind & Watertight or Cargo Worthy for one-trip new.

The 20ft works for almost every storage application Christian sees at the Brantford yards.

Residential renovation storage. A 20ft holds the contents of a three-bedroom Ontario house if you stack carefully. Furniture, boxed household goods, appliances. Buyers doing a kitchen reno, basement finish, or whole-house reno park one on the driveway for two to six months.

Construction job-site tool and material storage. Locked, weatherproof, mobile if needed. The 20ft is the universal job-site bin. Lockbox upgrade essential. A 20ft sits comfortably in a single parking-stall footprint when you need to share lot space with other trades.

Farm equipment shelter. Smaller Ontario farms use 20ft for feed, tools, ATV storage, seasonal equipment. Bigger operations go 40ft, but the 20ft is the right pick when you only need one bin.

Retail backstock and seasonal storage. Christmas tree lots, garden centres, ski-rental shops, pumpkin patches. The 20ft is portable enough to move site-to-site between seasons.

The 20ft also has the best secondary market in Canada. When you finally outgrow it or no longer need it, you can resell it. The pool of buyers is enormous because the 20ft is what every farm, contractor, and small business uses. Depreciation on a Corten steel 20ft is genuinely slow because the underlying steel commodity holds value and the size is universally usable.

The high cube version of the 20ft (9’6″ external height instead of 8’6″) adds about a foot of internal headroom and to the purchase price. Worth it if you are storing tall items, hanging shelving from the ceiling, or planning a future conversion to a workshop or office. Standard height is fine for most household and tool storage.

If we had to pick one container to recommend to a buyer who refuses to answer any of our sizing questions and just wants a guess, the answer is a 20ft standard dry, Wind & Watertight grade, used. It would work for roughly seventy percent of Canadian buyers who walk into the yard. The full 2026 Canadian container pricing breakdown goes deeper on what each grade actually costs.

40ft standard vs 40ft high cube: that extra foot of headroom

The 40ft is where the cube math gets interesting. The container is exactly double the length of a 20ft (40’0″ versus 20’0″) but only about 60 to 80 percent more expensive in purchase price. That means cubic-foot pricing on a 40ft is significantly better than a 20ft. If you have enough stuff to fill a 40ft, you are getting better value per cube than two 20ft units.

Used 40ft standard dry pricing in Ontario. Used 40ft high cube. One-trip 40ft (new from China, one ocean voyage to Canada to deliver cargo, then sold). Rental rates start around per month standard or per month for high cube.

The standard versus high cube question gets asked on every 40ft conversation. The difference is one foot of vertical height: 8’6″ external on a standard, 9’6″ external on a high cube. Internal headroom on a high cube is roughly 8’10” instead of 7’10”. That foot matters more than people think.

The other 40ft consideration is the high-cube transport restriction. A 40ft HC is 9’6″ external, which puts the top corner casting at about 9’8″ above the truck deck on a standard chassis. Some older rail bridges in Canada have clearances around 9’6″, which is why CN and CP rail intermodal moves through certain mountain passes still require confirmation before booking. For a buyer placing the container on a yard or job site, this is a non-issue. For someone moving the container between sites by rail, it is worth checking with the carrier. Road transport on standard chassis is fine in all Canadian provinces.

For long-term storage, the high cube is the better pick. The extra foot of headroom costs about 8 percent more and unlocks pallet stacking, future modification, and resale to buyers who specifically want HC for conversion projects. The HC also resells slightly better than standard because the secondary market for conversion-grade containers favours high cube.

For short-term storage where you do not need the height, the standard is fine and saves a few hundred dollars. Our shipping container types guide walks through every variant including standard, HC, reefer, flat rack, and open-top.

45ft high cube: when the extra five feet actually pays for itself

The 45ft high cube is the largest standard container in the Canadian market. External length 45’0″, which is five feet longer than a 40ft. Always built as high cube (9’6″). Internal capacity about 3,040 cubic feet versus 2,690 on a 40ft HC. Used 45ft HC pricing in Ontario with one-trip units at.

The 45ft is a niche pick. It exists because pallet-shipping math favours it: a 45ft can hold 28 standard Euro pallets (1200mm x 800mm) double-stacked, versus 24 in a 40ft HC. That is 17 percent more cargo for 12 percent more container cost on the purchase, which is a meaningful per-cube savings if your operation moves enough freight.

The 45ft is the right call in three specific cases.

Industrial pallet operations. Manufacturers, beverage distributors, retail distribution centres. If your operation routinely fills 40ft HCs to the back wall, the 45ft gets you 350 more cubic feet at a small premium.

Equipment storage with long items. Lumber, structural steel, irrigation pipe, conduit. Anything that comes in 40-foot lengths technically fits in a 40ft but does not stack with anything else. The extra five feet on a 45ft gives you cross-stacking room.

Container conversion at scale. Office conversions, mobile classrooms, retail pop-ups. The extra five feet of interior length translates into useful additional floor area when you build out walls, electrical, and furniture.

The 45ft is the wrong call for most buyers because of two limitations. First, the footprint. You need 47 feet of pad and 80 feet of truck approach. Most residential lots cannot accommodate that. Second, the secondary market. There are fewer buyers for a 45ft than for a 20ft or 40ft, so resale takes longer and prices are softer relative to original purchase.

For a Brantford or Hamilton industrial buyer with the yard space and the pallet volume, the 45ft is the right answer. For a residential buyer or a small contractor, it almost never is. Christian sees a steady but small volume of 45ft purchases at the yard, mostly from food and beverage distributors, equipment dealers, and a handful of farm operations that store long lumber or pipe.

The decision tree itself (5 yes/no branches)

If you read no other section, read this one. Five questions in order. Answer each one yes or no and follow the branch. The size at the end is the right pick for roughly 90 percent of Canadian buyers.

Run through that ladder in order. The order matters because each question filters out a category. Q1 handles footprint. Q2 catches the majority of buyers (most go to 20ft). Q3 handles the second footprint check for buyers with bigger needs but tight sites. Q4 separates pallet/conversion buyers (HC) from bulk-freight buyers (standard). Q5 catches the rare 45ft case.

About seventy percent of the buyers who walk into the Brantford yard end up at 20ft. About fifteen percent end up at 40ft standard. About ten percent at 40ft HC. About three percent at 10ft. About two percent at 45ft HC. Those proportions have held steady for years and they match what other Canadian yards report.

If the decision tree gives you an answer that does not feel right, the most common reason is a misread of Q2. Buyers underestimate how much they have to store because their stuff is currently spread across a basement, garage, attic, and shed. Put it all in one place and the cube adds up faster than expected. Erring upward by one size is usually safer than erring down, with the exception of 45ft which is genuinely worse than 40ft if you do not have the freight volume.

Resale value by size when you outgrow the box

The reason container sizing matters even on a permanent purchase is resale. If your needs change, you sell the bin. Some sizes sell fast. Others sit. Knowing the resale market shapes the right purchase today.

Here is what the Canadian secondary market actually looks like in 2026.

The 20ft has the best resale market in Canada by a wide margin because every farm, contractor, and small business can use one. The 40ft HC is the second-best because conversion projects almost universally specify HC for the headroom. The 10ft and 45ft both have thin secondary markets because they suit narrower use cases.

The practical implication for sizing today: if you are uncertain whether you will keep the container long-term, the 20ft is the safest purchase because you can sell it inside a month if your situation changes. The 45ft is the riskiest because you may sit on it for months if you need to liquidate.

Corten steel itself does not depreciate quickly. The commodity (steel) holds value, and well-maintained containers can hold 70 to 85 percent of purchase price for ten years or more if stored on the ground (not stacked) with the doors greased and the floor kept dry. The depreciation is in the wear, not the steel.

Common sizing mistakes Christian sees at the yard

Thirty years of watching Ontario buyers walk in, look at the inventory, and try to pick a size has produced a fairly predictable list of mistakes. Here are the five Christian sees most often, with the right call for each.

Mistake 1: Buying too small to save money. A buyer needs about a 20ft worth of storage but buys a 10ft because it is cheaper. Four months later they call to buy a 20ft. They have now paid two deliveries (about round trip), they own two containers, and they are out almost the same money they would have spent on a single 20ft. The 20ft was cheaper than the 10ft after the second delivery.

Mistake 2: Buying too big on a tight site. A residential buyer with a 24-foot driveway buys a 40ft. The truck cannot place it. The driver has to leave with the container on board. Re-delivery to a different site costs another delivery fee, and now the buyer is paying us to find them a new pad. Measure the pad and the approach before ordering, not after.

Mistake 3: Choosing standard when you need HC. A buyer plans a future conversion into a workshop or office. They buy a 40ft standard because the price is lower than an HC. Eight months later they start the conversion and realise the sub-floor and drop-ceiling will leave them at 6’8″ of usable interior height. They sell the standard and buy an HC. The price difference at purchase is now a swing including delivery fees and resale discount.

Mistake 4: Two 20ft when a 40ft would have worked. Some buyers split a load across two 20ft units thinking it gives flexibility. Two 20ft costs more to purchase than one 40ft, takes more pad space (two 22-foot pads instead of one 42-foot pad), and creates more delivery cost. If the load fits in a 40ft, one 40ft is almost always the cheaper move. The exception is buyers who genuinely need bins on two different sites or who plan to move one and not the other.

Mistake 5: Buying 45ft as a flex. The 45ft sounds bigger and more impressive. It is also harder to place, harder to resell, and only saves cubic-foot pricing if you actually fill it. Buyers who think they “might fill it eventually” usually do not. The 45ft is the right answer for industrial pallet operations and specific equipment storage; it is the wrong answer for almost everyone else.
