Container Carton Capacity Calculator
Estimate whole-carton container capacity by comparing all six axis-aligned carton orientations in a clear space.
Your results
Calculation breakdown
- Grid count
- maximum of floor(clear L ÷ carton axis 1) × floor(clear W ÷ axis 2) × floor(clear H ÷ axis 3)
Worked example
A 5.9 × 2.35 × 2.39 m clear space with 0.6 × 0.4 × 0.3 m cartons fits 315 in the best single-orientation grid.
Assumptions
- Cartons are axis-aligned rectangular cuboids.
- The full entered container dimensions are usable clear space.

How this calculator works
Estimate whole rectangular cartons fitting in a container for all six axis-aligned carton orientations and return the best grid count. All six orthogonal orientations are considered, making the result more useful than testing only a carton rotated on the floor. The result is kept transparent so the entered measurements can be checked against source records, physical labels and the operating plan before it is used.
Frequently asked questions
What should I verify for the container carton capacity result?
Use minimum clear internal dimensions and test the proposed pattern against doors, corrugations, lashing points and handling access. Record the basis beside the result so another person can reproduce the estimate.
Why can the real container carton capacity outcome differ?
Mixed-orientation packing, pallets, dunnage, mass limits, load restraint and practical loading sequence can reduce capacity. Recalculate whenever a load, measurement, route or operating assumption changes.
Does this container carton capacity calculation prove compliance?
No. It is a planning calculation using the values entered. For this topic, use minimum clear internal dimensions and test the proposed pattern against doors, corrugations, lashing points and handling access. Confirm current Australian requirements and competent advice wherever safety, legal compliance or equipment selection is involved.
