How Big Is a 45ft High Cube Container?

A 45ft high cube shipping container measures 13.71 metres (45 feet) long, 2.44 metres (8 feet) wide, and 2.90 metres (9 feet 6 inches) tall on the outside. Inside it holds about 86 cubic metres, roughly 13% more volume than a 40HC on the same footprint. The width and height match a 40HC; only the length grows.

A 45ft high cube container looks like a 40HC that someone stretched by five feet, and that is functionally what it is. The frame holds the same 8ft width and 9ft 6in height as a 40HC, but adds 1.52 metres of length. The ISO designation is 45’G1, falling under ISO 668 for classification and ISO 1496-1 for general cargo specification. Built by the same factories that turn out 20ft and 40ft stock (China International Marine Containers, Singamas, CXIC), they roll off the line on the same Corten weathering-steel construction with marine-grade plywood floors and double swing doors at one end.

External length is 13.71 metres (45 feet flat). External width holds at 2.44 metres (8 feet). External height is 2.90 metres (9 feet 6 inches), the high cube standard. Interior length runs roughly 13.56 metres because the corrugated end walls and door frame eat a few centimetres. Interior width is 2.35 metres after the corrugation. Interior height is 2.70 metres (8 feet 10 inches), giving you the same extra foot of headroom a 40HC delivers.

The numbers that matter for a buyer comparing capacity: interior volume runs 86 cubic metres (about 3,040 cubic feet). A 40HC sits at 76.3 cubic metres (2,697 cubic feet). The 45HC gives you roughly 9.7 cubic metres more interior space, or about 13% more usable volume on essentially the same yard footprint. That is the headline number behind every 45HC purchase decision: same width, same height, same parking pad, 13% more inside.

Tare weight is heavier because there is more steel: a typical 45HC empties out at 4,800 kilograms (10,580 pounds), compared with about 3,900 kg for a 40HC. Maximum gross weight is 32,500 kg (71,650 lb), and maximum payload runs about 27,700 kg (61,070 lb). The interesting wrinkle here: a 40HC can sometimes carry slightly more payload because its lower tare leaves more headroom under the same gross-weight cap. For heavy dense cargo (steel coil, machinery, sand), a 40HC actually maxes out legal weight before a 45HC does. The 45HC wins decisively only when cargo is voluminous but not unusually heavy.

Christian LeBlanc, who runs the yard with his father Paul, puts the size choice plainly: “The number people latch onto is the extra five feet, but what they are really buying is 13% more cube on the same parking pad. If your stuff is light and bulky, that is free space. If it is heavy, the weight cap catches you first and the length does nothing for you.” The LeBlanc family has operated Van Blanc out of Brantford since 1995, and Christian grew up in the trade, traveling to Asia with Paul from age 15.

One number not on most spec sheets but matters in the yard: ground clearance. A 45HC sits at about 165 mm (6.5 inches) at the bottom rail, the same as a 40HC. The corner castings line up on the ISO 1161 grid spaced at 40ft pitch (the back two castings sit at the 40ft mark even on a 45HC, with the front overhanging by 5 feet). That detail matters for chassis and twist-lock compatibility, covered below.

What Is ISO 1496-1 and Why Does the CSC Plate Matter?

The 45HC is a fully ocean-rated ISO container. That is not marketing language. ISO 1496-1:2013 is the international standard for series 1 freight container specification and testing, covering everything from base lifting to stacking, racking, end-wall strength, side-wall strength, floor concentrated load, restraint forces, water-tightness, and weather-tightness. A 45HC built to ISO 1496-1 passes a stacking test rated at 8 times its maximum gross weight (260,000 kg load on top), which is what makes a six-high stack on a container vessel safe in heavy seas.

Sitting alongside ISO 1496-1 is the CSC plate, the safety certificate required by the 1972 International Convention for Safe Containers (IMO). Reading that plate correctly is one of the things we walk first-time buyers through before they pay for any used unit. The CSC plate is a metal data plate riveted to the container door (usually on the left) listing the manufacturer, manufacture date, serial number, ACEP scheme or next-inspection date, maximum gross weight, allowable stacking weight, and racking test load. Without a valid CSC, the container cannot legally move in international maritime trade.

This is where the 45HC story diverges from the 53ft North American domestic container, and the difference matters for buyers who are choosing between sizes. 45HC units are ocean-rated and CSC-plated. They came across the Pacific on a vessel, they meet the ISO 1496-1 structural tests, and they carry the metal plate proving it. 53ft containers are not ocean-rated. They are built to AAR (Association of American Railroads) standards for domestic intermodal rail and truck use only, with thinner steel, lighter framing, and no CSC plate. A 53ft cannot move on an international vessel because no shipping line will load a non-CSC unit, and customs at every port stops them.

What does ocean-rated mean for a buyer who is never putting the container on a ship? It means the steel is thicker, the corner castings are heavier, the corrugation is more aggressive, the floor joists are denser, and the racking strength is higher. The same steel that lets a 45HC survive a Pacific crossing lets it survive a Canadian winter, a forklift hit, a snow load, or a 30-year service life on a back lot. ISO 1496-1 compliance is structural insurance you cannot see but you can feel in how the doors close on a 10-year-old unit.

Is a 45HC Ocean-Rated, and How Does It Compare to a 53ft?

The 45HC sits at an unusual point in the container catalogue. It is the largest size that still gets manufactured to full ocean-rated ISO 1496-1 specification with a CSC plate. Step up one size to a 53ft and you cross into the AAR domestic build standard, which is a structurally different animal: lighter steel, no CSC, no Pacific crossings, no stacking certification beyond domestic rail. Step down to a 40HC and you stay in the ocean-rated family but lose 5 feet.

This positioning shapes who actually buys 45HC stock. Three buyer profiles dominate. One-trip importers moving voluminous low-density cargo (apparel, plastics, consumer goods, automotive parts) use 45HC because the extra 13% volume on the same drayage cost improves freight economics. Container conversion specialists building modular offices, residential ADUs, or commercial pop-ups use 45HC because the extra 5 feet allows interior layouts that 40HC cannot accommodate. Industrial buyers needing high-capacity storage on a fixed yard footprint use 45HC because every cubic foot of stored material is one less unit they have to manage.

What 45HC buyers almost never include: long-haul road carriers running domestic Canadian freight. That market is owned by the 53ft because Transport Canada road regulations and tractor configurations are optimised around the 53ft footprint, and the AAR build is lighter weight, which lets carriers maximise payload under highway weight limits. If you want a domestic trucking container, 53ft is the answer. If you want an ocean-rated container with extra length, 45HC is the answer. Different tools, different jobs.

Should You Buy a 45HC or a 40HC?

The 45HC versus 40HC question is what brings most buyers to this page. They have already decided on a high cube. They have already ruled out 20ft. The choice comes down to 40HC versus 45HC, and the price gap is real but modest. If you are still weighing the smaller box, our breakdown of the standard versus high-cube 40-footer covers that earlier fork in the road. Across the Canadian market in May 2026, one-trip 45HC carries a single-digit-percentage premium over one-trip 40HC, reflecting the extra steel and the thinner supply of 45HC units. Used cargo-worthy 45HC carries a similar premium over CW 40HC. The question is whether the extra 5 feet justifies the extra cost.

The answer is shaped by what the container is for. Five buyer questions resolve the decision.

Question 1: Is your cargo or stored material voluminous but not unusually heavy? Apparel, plastics, consumer goods, foam, packaging materials, and seasonal inventory all benefit from the extra 13% volume because they fill the box on cube before they hit the weight limit. For these cargoes, 45HC always wins. If your cargo is dense (steel coil, machinery, building materials, sand, scrap metal), the 40HC might max out legal weight before you can fill the 45HC, so the extra length is wasted.

Question 2: Are you converting the container to a habitable or working space? A 40HC interior runs 12.03 metres long. A 45HC runs 13.56 metres long. That 1.53 metres (5 feet) is the difference between a tight conversion and a comfortable one. Five feet is enough to add a full bedroom, a separate office, a kitchen extension, an extra workbench, or a vestibule. For residential conversions and commercial workspace builds, the 45HC is meaningfully more flexible.

Question 3: Will you ever ship the container internationally? Both 45HC and 40HC are CSC-plated and ocean-rated, so this question is neutral between the two. But if the answer is yes, both win against a 53ft. Worth confirming because it sometimes flips the decision against going larger to a 53ft.

Question 4: Does your yard or property accommodate the extra length? A 40HC needs about 14 metres of clear length for placement (12.19m container plus 1.5m for forklift or tilt-deck clearance). A 45HC needs about 15.5 metres. Most rural and industrial properties accommodate either; some urban driveways and tight commercial lots cannot fit the 45HC. Measure before ordering. Christian or Paul will walk you through the placement question on the call.

Question 5: Is local availability a constraint? 45HC stock is thinner than 40HC stock across the global fleet. In Ontario, some yards carry 45HC and some do not. Lead times can stretch from a few days (when stock is on the yard) to a few weeks (when an order has to source from a partner yard or the next inland arrival). 40HC stock is universally available. If you need a container in 48 hours and have flex on the length, 40HC sometimes ships faster.

What Is a 45ft High Cube Container Used For?

The 45HC has a different buyer profile from the 20ft and 40ft. It does not show up much in farm storage, secondary tool sheds, or general industrial back-lot use. Those are the 20ft and 40ft territories. The 45HC instead shows up in specific use cases where the extra five feet unlocks a layout or function that the smaller sizes cannot support.

Workshop with truck pull-through. A 45HC fitted with a roll-up door on each end becomes a 45-foot covered drive-through workshop. Park a long-bed pickup or a small flat-deck trailer entirely inside with room to walk around it. The same 40HC layout leaves the truck nose sticking out. For mechanics, fabricators, classic-car restorers, and outdoor-equipment service operations, the extra five feet is the difference between working under cover and working with the doors open in February.

Mobile event space. Pop-up bars, corporate event lounges, sponsor-branded experiences, mobile coffee shops, and festival kiosks built into 45HC frames give organisers a longer interior runway. A 40HC pop-up bar tends to feel tight when you add a back-bar, a serving counter, a register zone, and a small storage corner. The 45HC layout breathes. Event-rental operators we have seen in the Brantford area run multi-unit fleets specifically because the 45HC reads as more polished on site.

Modular construction build longer than 40 feet. Modular site offices, classroom modules, healthcare modules, and remote-site bunkhouses sometimes need a layout longer than 40 feet but cannot accept the build-quality compromises of a 53ft. The 45HC fits this gap: 5 feet more layout space than 40HC, full ISO 1496-1 structural integrity, CSC-plated for ocean transport if the unit is being deployed to a remote international project. This is the niche where 45HC stock most often gets bought by container conversion specialists.

High-density industrial storage. Manufacturing facilities, distributors, and warehouse operators who need to maximise stored cubic feet on a fixed yard footprint stack 45HC units instead of 40HC and gain 13% more storage per stack. Over a 10-unit yard array, that math compounds: ten 45HC units hold the equivalent of about 11.3 forty-foot HC units of cargo. For high-turn inventory, the math justifies the modest unit-price premium quickly.

Long-stock storage. Steel suppliers, lumber yards, electrical and plumbing wholesalers, and HVAC distributors stocking long pipe, conduit, dimensional lumber, or rigid product runs often need lengths in the 12 to 13 metre range. A 40HC interior at 12.03 metres is uncomfortably tight for 12-metre stock. A 45HC at 13.56 metres gives you 1.5 metres of work room to load and unload long product without standing on a forklift to wrestle it through the door.

Is a 45HC Good for a Backyard ADU or Container Home?

Residential conversion is the growth segment for 45HC sales in Canada, and Christian sees it on the call sheet more often than any other use case as of 2026. Backyard accessory dwelling units (ADUs), garden suites, secondary suites, in-law units, and tiny-home conversions built from shipping containers have become a real category in Ontario, with garden-suite and ADU projects multiplying across the province over the last three years. The 45HC has emerged as the size of choice for these conversions because of the layout math.

A 40HC interior at 12.03 metres by 2.35 metres gives you about 28 square metres of floor space. That is enough for a studio layout (bed, kitchenette, bathroom, small living area) but tight for anything more. A 45HC interior at 13.56 metres by 2.35 metres gives you about 32 square metres, a 14% increase. That extra 1.53 metres is exactly the dimension a designer needs to add a small separate bedroom, a closet zone, or a vestibule entry that keeps the bathroom door from opening into the main living area.

The reason 45HC beats 53ft for residential conversion is structural. ISO 1496-1 compliance and the CSC plate give engineers a known structural baseline to work from. The container’s racking strength, stacking certification, and corner casting locations are all standard ISO values that show up cleanly on engineered drawings. A 53ft AAR domestic build does not have the same documented structural envelope, which makes the engineering harder to sign off. Conversion specialists prefer the 45HC because the engineering pathway is well-trodden.

The 45HC conversion buyer tends to be informed. They have priced both new modular construction and stick-built ADU alternatives. By the time they call us, the question is no longer “should I use a container” but “which size and which grade.” Christian’s job on those calls is to confirm the 45HC fits their yard and their layout, walk them through one-trip vs CW pricing, and book a yard visit so they can see the container before they pay.

Common residential 45HC builds we see come through the yard: backyard guest suites (parents, adult children, rental units), home-office studios for remote workers needing separation from the house, painter and ceramicist studios, cottage country secondary dwellings, and stacked two-unit duplex builds (two 45HCs side-by-side with a connecting deck on top). The container itself is one input in a build that also includes insulation, electrical, plumbing, HVAC, windows, doors, interior finish, and exterior cladding. If you are mapping out what happens to the steel after it lands, our rundown of how containers get turned into finished spaces walks through the cut-and-frame stages most buyers do not picture up front. Total all-in conversion cost is driven mostly by finish level rather than the container itself, and typically lands well below the cost of an equivalent stick-built ADU.

What Drives the Price of a 45HC in Canada?

The price of a 45HC in Canada is driven by four things: grade (one-trip versus used), container origin, the global supply of 45HC stock, and the delivery route to your site. Pricing has been relatively stable through Q1 and Q2 of 2026 after the volatility of 2022-2024. Three grades sort into three tiers, summarised below as relative positions rather than posted numbers, because the market on a specialty size moves week to week and a stale figure helps no one. Delivery is always quoted separately per route. For brand-new one-trip stock specifically, our page on ordering fresh factory units covers what the newest-steel option looks like before it reaches the yard.

One-trip 45HC sits above one-trip 40HC in the Canadian market. The premium reflects two real cost factors: more steel per unit (the tare weight is 900 kg higher) and lower volume in the global fleet (about 5% of total container production is 45HC, vs about 50% for 40HC standard plus high cube). When supply tightens (sometimes seasonal, sometimes route-dependent on the rail haul from coast to inland), the 45HC premium widens. When supply loosens, it compresses.

Used 45HC pricing is more variable because the secondary market is thinner. A cargo-worthy 45HC that just came out of fleet rotation tends to sit at the upper end of the used range, while the same grade can soften when a seller is moving inventory ahead of new arrivals. WWT 45HC stock is harder to find consistently and pricing reflects scarcity rather than condition. If a buyer needs a specific grade in 45HC and the market is tight, sometimes the right answer is a 40HC at lower cost and faster availability.

Where Can You Find a 45HC in Stock in Ontario?

The 45HC is a real-but-niche size in the global container fleet. Industry data places 45HC production at roughly 5% of new container output, compared with about 40-50% for 40HC and 30-40% for 20ft standard. The number on the yard at any one time reflects that production ratio. Most Ontario yards carry a deep 20ft and 40HC inventory and a shallower 45HC inventory, sometimes none at all if the yard is small or specialises in entry-level storage stock.

Van Blanc holds 45HC inventory across our four Brantford yards as a standing decision. The reasoning is operational. Conversion specialists, modular builders, motorsport buyers, and residential ADU customers ask for 45HC specifically. If we do not have one on the yard, we cannot serve them quickly. So we keep one-trip and CW 45HC stock rotating through, even though the turn is slower than 40HC. Most weeks we have at least one of each grade available; some weeks we have several. The rest of the bins we currently have ready to move sit beside the 45HC stock on the same Brantford lots. Christian or Paul will tell you on the call exactly what is on the yard that week.

Lead time from us follows a simple pattern. If the size and grade is on the Brantford yard, delivery to most Ontario destinations runs 1 to 3 days. If we need to source from a partner yard, lead time extends to 5 to 10 days. If the unit needs to be ordered from an inland arrival or a manufacturer (rare for 45HC unless the buyer wants a specific colour or modification), lead time extends to 2 to 6 weeks. Every quote we give comes with the real lead time on that specific unit, not a hopeful one.

How Is a 45HC Delivered from Brantford?

A 45HC ships on the same tilt-deck or roll-off trailer as a 40HC, but the truck-and-trailer combination is closer to its legal length limit. The 45HC is 13.71 metres long. Most Ontario tilt-deck trailers carry to 14 metres comfortably. A 53ft runs past what a standard tilt-deck handles and needs specialised oversize haulage. Site access for a 45HC delivery needs roughly 23 metres of straight pull-in path (trailer length plus tractor plus turnaround), and overhead clearance of about 4.5 metres for the tractor cab.

Delivery from our Brantford yards to most of Southern Ontario lands inside 1 to 3 business days. Niagara, the GTA, Cambridge-Waterloo, Hamilton, London, Norfolk-Haldimand, and the wider Grand River region are all single-day routes. Eastern Ontario (Kingston, Brockville, Ottawa) runs 1-3 days. Northern Ontario (Sudbury, North Bay, Sault Ste. Marie) is quoted per route at 5 to 10 days because freight is premium and routing is longer. Every quote includes the real lead time, not a hopeful one.

Site prep for 45HC placement: a flat pad of crushed stone or compacted gravel, sized at least 4.5 metres wide by 15 metres long. Corner blocks (railway ties, concrete piers, or steel blocks) at each of the four corner castings keep the container off the ground and let air circulate underneath, which is the single biggest factor in long-term rust prevention. Skipping the corner blocks and resting the container directly on soil is the most common reason a 10-year-old container shows underside rust. The container will sit on those blocks for the next 25 to 30 years. Get them right at delivery.

How Do You Avoid 45HC Scams on Facebook Marketplace?

Avoiding a 45HC scam on Facebook Marketplace comes down to one rule: never pay for a container you have not seen. The Facebook Marketplace scam wave that has hit the 20ft and 40ft container market has spread into the specialty sizes, including 45HC. The pattern is identical: a listing appears at below market, a non-local seller offers free or low-cost delivery, the buyer pays an “escrow” or “shipping coordinator” up front, and the container never arrives. Specialty sizes are particularly attractive to scammers because buyers searching for 45HC, 53ft, or reefer units tend to assume specialty pricing is more variable, which lowers their fraud alarms.

Many people call Van Blanc saying they found a 45HC far below the market on Facebook. Two weeks later they call back saying they got scammed. Don’t fall for it. The bin that looks suspiciously cheap on Facebook is the bin that never arrives, and the pattern repeats every week. Christian or Paul can walk you through the warning signs on a five-minute call.

The protection pattern is the same as it has been for 30 years. Visit the yard or have eyes on the actual container before any payment leaves your account. Confirm the seller has a verifiable physical address (not a PO box, not a Gmail address with no website). Cross-reference the seller’s reviews on Google with the timestamps and the photos. Do not wire funds, do not pay through Cash App, Venmo, or cryptocurrency. COD or wire-after-delivery is the only safe payment pattern.
