Pallet Carton Count Calculator
Estimate whole cartons per pallet layer and pallet across two right-angle packing orientations and entered layers.
Your results
Calculation breakdown
- Grid cartons per layer
- maximum of floor(pallet L ÷ carton L) × floor(pallet W ÷ carton W), including 90° rotation
Worked example
A 1,200 × 1,000 mm usable pallet with 400 × 300 mm cartons fits nine per layer in the better orientation and 45 over five layers.
Assumptions
- One orientation is used across each rectangular layer.
- Cartons have no overhang and dimensions include packaging tolerances.

How this calculator works
Estimate whole cartons per pallet layer and per pallet for two orthogonal carton orientations, then identify the better rectangular layout. Testing both 90-degree orientations avoids losing an obvious packing improvement while keeping the layout conservative and grid-based. 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 pallet carton count result?
Use external carton and usable pallet dimensions, then trial the pattern for gaps, overhang, stability and handling clearances. Record the basis beside the result so another person can reproduce the estimate.
Why can the real pallet carton count outcome differ?
Mixed orientation, interlocking, compression, pallet mass, height, corner protection and irregular cartons are not optimised. Recalculate whenever a load, measurement, route or operating assumption changes.
Does this pallet carton count calculation prove compliance?
No. It is a planning calculation using the values entered. For this topic, use external carton and usable pallet dimensions, then trial the pattern for gaps, overhang, stability and handling clearances. Confirm current Australian requirements and competent advice wherever safety, legal compliance or equipment selection is involved.
