集装箱装载计算器

The calculator estimates volume utilisation by dividing total carton CBM by the container's usable volume. It also estimates how many cartons could theoretically fit, based on volume alone, assuming perfect cubic packing. It does not account for carton orientation, stacking patterns, weight distribution, or actual physical loading constraints.

A 20ft standard container has approximately 33 CBM of internal volume, but effective usable volume (accounting for door swing clearance, load bracing and packing efficiency) is typically 25–28 CBM. This calculator uses 28 CBM as the planning usable volume. Actual usable volume depends on cargo stacking height, pallet configuration and your freight forwarder's loading method.

Full Container Load (FCL) generally becomes more cost-effective when a shipment exceeds 12–15 CBM in a 20ft container, or 25–28 CBM for a 40ft. However, cost depends on lane, carrier and market conditions. FCL also provides faster transit (no consolidation waiting), less cargo handling, and lower damage risk. Always compare FCL vs LCL rates from your forwarder for the specific lane.

A 20ft standard container has a maximum gross weight (container tare + cargo) of approximately 30,480 kg, with a typical maximum payload of 21,600–28,200 kg depending on the container grade. A 40ft standard container typically carries up to 26,760 kg payload. Weight limits are set by the shipping line and road transport regulations — both must be respected.

A High Cube (HC) container is 30 cm taller than a standard container — typically 269 cm internal height versus 239 cm. This provides approximately 10–15% more volume per container length. High Cube containers are ideal for light but tall cargo. The 40ft High Cube is the most commonly used container in international trade for general cargo.

This calculator assumes perfect cubic packing — that every cubic centimetre of carton volume fits neatly against every other. In practice, cartons have fixed orientations (some cannot be turned on their side), some stack above load height restrictions, and physical loading requires lanes for forklifts and strapping points. A practical loading efficiency of 70–85% of the theoretical maximum is common. The estimate shown is a planning guide, not a guaranteed load plan.
