TI is boxes per layer; HI is number of layers. Total boxes ≈ TI × HI.

When should I allow 90° rotation?

Enable rotation to try both orientations and pick the larger per‑layer count. Some products restrict orientation due to labeling or stability.

They are planning estimates that ignore minor tolerances and packaging deformation. Verify with your logistics provider.

TI‑HI Calculator

Compute boxes per layer (TI) with/without 90° rotation, then estimate layers (HI) by a stack height. Includes EU/US presets plus AU/JP.

We compute TI both at 0° and 90° orientations when rotation is allowed and pick the larger (ties prefer 0°).
Optional gap/overhang reduce the effective pallet area when calculating rows × columns.
