Methodology
Transparent calculations with clear limits.
The planner uses related methods so every estimate can be understood and checked.
Last reviewed: September 2, 2026Same-size layer and height estimate
Perimeter clearance is removed from both sides of the pallet length and width. The tool calculates whole rows and columns in one orientation, repeats the calculation after turning every box 90 degrees, and shows the higher count. It then divides the available load height by the outside box height to estimate complete layers. The 3D view illustrates those dimensions; it does not validate stability.
Mixed-size freight estimate
The freight-saving option first fills open positions on the pallet deck with a largest-first floor-packing heuristic and tries both box orientations. It then adds boxes to the lowest fully supported column. At the same height, an upper box may slide inside the footprint of its single supporting box so equal cartons form a tighter block. Every upper box must still fit entirely inside that one support; boxes that cannot be supported within the height or payload limit move to another pallet. The simple-layer option keeps one size per layer.
Weight and compression inputs
Declared box weights can prioritize heavier boxes on the pallet deck and enforce an optional pallet payload. In freight-saving mode, if a tested allowable top load is also entered, the planner totals every known weight transmitted through each column and rejects a demonstrated excess. Zero or missing values keep the overall compression check incomplete; simple-layer mode does not apply this top-load calculation.
What is excluded
An allowable top load is not inferred from ECT, burst strength or the maximum contents weight printed on a box certificate. The planner does not account for humidity, storage time, box age, closure, contents, dynamic handling or every loss factor that affects real box compression. It also does not prove stability, securement, equipment access, door clearance or compliance.
