What Is Ti × Hi?

Ti × Hi (sometimes written TiHi or Ti-Hi) is the standard warehouse notation for a pallet's stacking pattern. Ti (tier) is the number of cases per layer, and Hi (high) is the number of layers stacked on the pallet. A 9×5 pallet holds 9 cases per layer across 5 layers — 45 total cases. Knowing Ti × Hi at a glance lets receivers verify pallet completeness, lets pickers know how many cases they're taking, and lets planners calculate truck loads.

Pattern Strategies

Column is the standard floor-division grid — all cases in the same orientation. Interlock alternates two layer orientations (A/B) for pallet stability, a common practice in warehouse operations. Pinwheel arranges four cases per tile in a windmill pattern, useful when cases are nearly square. Mixed orientation fills the primary grid in one direction, then rotates cases to fill the leftover strips. The tool compares all four and highlights the best fit.

Mixed-Pallet Planning

Mixed Layer mode packs 2–5 different SKU sizes onto a single pallet layer — useful for order fulfillment when shipping partial cases of multiple products. The algorithm tests every orientation and ordering combination to find the densest shelf-based layout. Layer Stack mode places different SKUs on separate layers with priority-based stacking (heavy on bottom, fragile on top), calculating cumulative height and weight against pallet limits.

Use the Pallet & Container Calculator for container-level load planning, the Bill of Lading Generator for shipping documents, and the Container Loading Planner when loading mixed-SKU pallets into a container. On the receiving end, the Multi-Vendor Receiving Dock Scheduler places these inbound pallets into dock and time slots so trucks aren’t queueing in the lot.
