Container Load Calculator
How It Works
Maximizing container utilization is key to reducing per-unit shipping costs in international trade. This calculator determines how many cartons fit inside standard shipping containers by considering both volume constraints and weight limits.
A standard 20-foot container has internal dimensions of approximately 233 x 92 x 89 inches (1,172 cubic feet). A 40-foot standard container doubles the length to 474 inches (2,390 cubic feet). High cube containers add 13 inches of height (102 inches internal).
Weight limits are equally important. A 20-foot container has a maximum payload of about 47,900 lbs, while 40-foot containers allow approximately 58,800 lbs. Dense cargo like machinery or beverages often hits the weight limit before filling the space.
Frequently Asked Questions
What is the difference between a standard and high cube container?
A high cube (HC) container is 1 foot taller than standard — 9.5 feet vs 8.5 feet internal height. The length and width are the same. HC containers are preferred for lightweight, voluminous cargo to maximize cubic capacity.
How many pallets fit in a 40ft container?
A 40-foot container fits 20-24 standard pallets (48x40 inches) in a single layer depending on arrangement. With stacking, you may fit 40-48 pallets. Always verify with your carrier for loading specifications.
What is container tare weight?
Tare weight is the empty container weight: about 5,070 lbs for a 20ft, 8,380 lbs for a 40ft, and 8,600 lbs for a 40ft HC. The maximum gross weight minus tare weight equals maximum payload.
How can I improve container utilization?
Design carton dimensions to divide evenly into container dimensions, use floor-loaded cartons instead of pallets when possible, fill void space with smaller items, and consider mixed container loads.
