Carton Optimization Tool
Maximize your shipping efficiency. Calculate the best stacking orientation to fit more units per box and reduce your total CBM.
Product Size (cm)
Carton Inner Size (cm)
Inner dimensions provide the most accurate results.
85–95% efficiency is realistic for most stacked products to account for padding, human error, and structural integrity.

Why Carton Optimization Matters
Every cubic centimeter of "air" in your shipping container is money wasted. Carton optimization ensures you are utilizing the maximum volume of your shipping boxes, which directly reduces your total CBM (Cubic Meters) and freight costs.
Lower Shipping Costs
Small improvements in stacking can reduce the total number of cartons needed by 10-20%, drastically cutting sea freight bills.
Reduced Damage
Properly optimized cartons have less "void space," meaning products are less likely to shift and break during transit.
Carton Optimization FAQ
Why does wasted space increase shipping cost?
Freight is priced by volume (CBM). Empty space inside cartons still counts toward your total volume, so you pay for the air inside the box.
Should I use inner or outer carton dimensions?
Always use Inner dimensions for stacking calculations. Outer dimensions are only needed for the final CBM calculation used by the carrier.
What is packing efficiency?
This factor accounts for cardboard thickness, bubble wrap, and stacking errors. A value of 90% is a safe industry standard for planning.
