Layer planning

TI-HI Calculator

Calculate cases in one complete layer (TI), full layers (HI), and the resulting full-layer case count. Mixed 0°/90° footprints and every active limit remain visible.

Calculation workspace

Start with the case and pallet you will actually use.

Blank limits stay blank. A TI-only result does not invent a one-layer HI, and gross weight remains unknown until pallet tare is supplied.

Method

What this TI-HI result means

The footprint search and the vertical constraints are kept separate so no assumption is hidden inside a single number.

1. Find TI

Place identical rectangular case footprints inside the usable pallet footprint. Mixed results may combine 0° and 90° placements.

2. Find or validate HI

Count only complete layers that meet the entered height, gross-weight and rated-payload inputs, or test a planned layer count.

3. Keep the scope visible

TI × HI is used only for identical complete layers. Alternating, irregular and partial layers need a separate count.

Planning limits

Geometry is not load approval

Before loading, confirm case compression strength, center of gravity, stack stability, overhang, restraint, pallet condition, rack and forklift ratings, vehicle limits and site rules.

Need coordinates?

Open the configuration calculator for individual placements.

Use the same dimensions to inspect mixed layouts and placement coordinates. Neither tool models the physical loading sequence or transport stability.

FAQ

TI-HI questions

What do TI and HI mean?

TI is the number of cases in one complete pallet layer. HI is the number of complete layers in the palletized load.

Can TI multiplied by HI always be used as the total case count?

Only when every counted layer is a complete, identical layer. Alternating, irregular or partial layers require a separate count.

Does this TI-HI result certify a safe pallet load?

No. It is a geometry and arithmetic planning result. It does not evaluate case compression, center of gravity, stability, restraint, pallet condition, handling equipment or transport rules.

How are height and weight constraints applied?

Height uses the entered pallet height plus full case layers. A gross-weight limit first subtracts pallet tare and packaging extras; a rated pallet payload is checked separately against product weight.
