Shipping Container Sizes & What Actually Fits集装箱尺寸与实际装载量
Last reviewed: June 2026 · 4 minute read最后审核：2026年6月 · 约4分钟阅读
Container specs are easy to find; what trips importers up is the gap between theoretical capacity and what loads in practice. Here are the standard boxes with both numbers.集装箱规格很容易查到；让进口商栽跟头的是理论容量与实际装载量之间的差距。以下是标准箱型的两组数字。

*Container max payload is rarely your real limit in Canada — road weight rules usually cap loaded containers lower, and the legal maximum depends on the truck configuration and province. Heavy, dense cargo (tiles, steel, machinery) often "weighs out" a 20' before it "cubes out". Tell us your commodity and lane and we'll confirm the loadable weight before your supplier stuffs the box.*集装箱最大载重在加拿大很少是您的真正上限——公路重量法规通常把重柜限制得更低，合法上限取决于车型和省份。重而密的货物（瓷砖、钢材、机械）往往20尺柜"先到重量上限"而不是"先装满"。告诉我们商品和航线，我们在供应商装柜前确认可装重量。
Special equipment特种设备
Reefer (RF) — temperature-controlled; usable volume is smaller than a dry box of the same length冷藏柜（RF）——温控；可用容积小于同长度干柜
Open top (OT) — for cargo loaded by crane or taller than door height开顶柜（OT）——用于吊装或超过门高的货物
Flat rack (FR) — machinery and out-of-gauge pieces; lashing and permits matter平板柜（FR）——机械和超限件；绑扎和许可很关键
FCL or LCL?整柜还是拼箱？
LCL is priced per cubic metre and makes sense for small shipments. Above roughly 13–15 m³, a 20' FCL usually wins: flat cost, no shared-container handling, less damage exposure, faster at destination. Run your cartons through our CBM calculator to see where you land.拼箱按立方米计价，适合小批量。超过约13–15立方米时，20尺整柜通常更划算：固定成本、无拼箱操作、损坏风险更低、目的港更快。用我们的CBM计算器算算您的箱子。
Dimensions and payloads vary slightly by container manufacturer and carrier. Verify critical specs against your carrier's equipment guide, or ask us.尺寸和载重因集装箱制造商和承运人略有差异。关键规格请与承运人设备指南核对，或咨询我们。

FAQ常见问题
Frequently asked questions常见问题
How many pallets fit in a 40-foot container?一个40英尺集装箱能装多少个托盘？▼
With standard North American 48"×40" pallets, a 40' container typically takes around 20–21 single-stacked; a 20' takes roughly half that. Actual counts move with pallet overhang, stacking, and how the load is turned, so confirm against your real pallet dimensions before booking. Cube isn't the only limit either — heavy pallets can hit weight caps first.使用北美标准48×40英寸托盘、单层摆放的情况下，40'柜通常能装20–21个左右；20'柜大约是一半。实际数量会随托盘超边、堆叠方式和摆放方向而变化，订舱之前请按您托盘的实际尺寸核实。而且立方数并非唯一限制——重货托盘可能先触到重量上限。
What is the maximum legal weight for a loaded container in Canada?在加拿大，重箱的法定最大重量是多少？▼
Less than the container's rated payload, in most cases — the binding limit on Canadian roads is set by provincial weight regulations and the truck/chassis configuration, not by the box. Dense cargo like tile, steel, or machinery frequently maxes out legally allowable weight well before the container is full. Confirm the loadable weight for your lane before your supplier stuffs the container; we can check this for a specific commodity and destination.多数情况下低于集装箱本身的额定载重——在加拿大公路上，真正起约束作用的上限由各省的重量法规和车头/底盘配置决定，而不是由箱子决定。瓷砖、钢材、机械这类高密度货物，往往箱子还没装满就先顶到法定允许重量。请在供应商装柜之前确认您运输线路的可装载重量；针对具体商品和目的地，我们可以帮您核查。
What's the difference between a 40' standard and a 40' high cube?40'标准柜和40'高柜有什么区别？▼
Height — the high cube runs about a foot taller inside, which adds roughly nine cubic metres of capacity for light, bulky freight. High cubes dominate the trans-Pacific fleet and are often priced the same or close to a standard 40', so for volume-driven cargo they're usually the default ask. For weight-driven cargo the extra cube buys you nothing.区别在高度——高柜内部大约高出一英尺，对轻抛货而言约多出九立方米的容积。高柜在跨太平洋航线的箱源中占主导，价格常常与标准40'柜持平或接近，因此对以体积为主的货物，高柜通常是默认之选。而对以重量为主的货物，多出来的立方数派不上任何用场。
What happens if my container is overweight in Canada?如果我的集装箱在加拿大超重会怎样？▼
An over-legal-weight container either needs special permits (where the route allows them) or has to be transloaded — de-stuffed into lighter road loads — before it can travel, both of which add cost and days. The fix is upstream: verify the legal loadable weight for your delivery lane at booking and hold the supplier to it. Catching it at the port is the expensive version.超出法定重量的集装箱要么申请特殊许可（前提是线路允许），要么必须转运——掏箱分装成较轻的公路载荷——之后才能上路，两种方式都会增加费用和天数。解决之道在上游：订舱时就核实派送线路的法定可装载重量，并要求供应商严格执行。等到了港口才发现，那就是最贵的版本。
Is LCL slower than FCL from China to Canada?从中国到加拿大，拼箱（LCL）比整柜（FCL）慢吗？▼
Usually somewhat — LCL rides the same vessels but adds consolidation at origin and de-consolidation at a destination CFS, each with its own cutoffs and handling queue. It also passes through more hands, which raises damage exposure. That's why the FCL-versus-LCL decision is about total cost and risk, not just the per-cubic-metre rate.通常会慢一些——拼箱与整柜坐的是同样的船，但在起运地多了集拼、在目的地多了集装箱货运站（CFS）拆箱环节，每个环节都有自己的截止时间和操作队列。经手环节更多，货损风险也随之上升。所以整柜与拼箱之间的取舍，看的是总成本和总风险，而不只是每立方米的运价。
