Ti Hi Pallet Calculator

Enter the pallet and case sizes to get Ti (cases per layer), Hi (layers high) and total cases per pallet. It tries mixed layer patterns, not just block stacking, so it often fits more than a simple divide-and-round — and it draws the layer so the floor can build it.

Everything runs locally: what you type never leaves your browser.

Mixed pattern: 1 more case per layer than block stacking (9). Hi is limited by height. Load height 56 in, payload 1500 lb.

One layer, viewed from above. Dashed outline is the pallet deck.

How Ti and Hi are worked out

Ti is how many case footprints fit on the pallet deck in one layer. The obvious method divides each deck side by a case side and rounds down, trying the case both ways round. This calculator also tries every mixed pattern where part of the layer runs one way and the rest turns 90°. In the example above, block stacking stops at 9 cases a layer; the mixed pattern fits 10, and since 10 × 192 sq in is exactly the deck’s 1,920 sq in, no layout can do better.

Hi is how many layers fit. Subtract the deck height from the maximum load height and divide by the case height — then check the weight: if Ti × Hi cases would exceed the pallet’s maximum payload, Hi drops until they don’t. The result says which limit binds, because the fixes differ: a height limit calls for a shorter case or a taller load allowance, a weight limit for lighter cases or a stronger pallet.

Cases per tier, interlocking patterns and metric pallets

Warehouses search for this as a cases per tier calculator, and European and Asian operators often need the ti hi pallet calculator metric version — switch the units above and the EUR, ISO and Asia pallet presets fill in their exact millimetre footprints. Mixed layer patterns are also what make an interlocking ti hi pallet layout possible, because turning alternate layers only works when the pattern is not a plain grid.

Where the numbers come from

Pallet footprints are the ISO 6780 standard sizes: 48 × 40 in (GMA), 1200 × 800 mm (EUR), 1200 × 1000 mm, 1100 × 1100 mm and 42 × 42 in. Deck heights and load ratings are typical figures only — pallets vary by construction and condition, so enter the rating for the pallets you actually ship on.

Frequently asked questions

What is Ti-Hi and how is it calculated?
Ti is the number of cases in one layer (tier) on the pallet, and Hi is the number of layers stacked high. Cases per pallet is simply Ti × Hi. Ti depends on how the case footprint packs onto the pallet deck, and Hi on how many case heights fit under the maximum load height once the pallet deck itself is subtracted — or on the weight limit, if that runs out first.
What is the weight limit for a standard 48 x 40 GMA pallet?
A common working figure for a standard GMA wooden pallet is about 2500 lb of evenly distributed load, which is the default here. The real rating depends on the pallet’s construction, wood, condition and whether it is being moved or sitting static in a rack, so check the rating for the pallets you actually use and enter it as the maximum weight.
Why is an interlocking pallet pattern safer than block stacking?
In a block (column) stack every case sits directly on the one below, so the load behaves like separate towers that can lean apart. An interlocking pattern turns alternate layers so each case bridges two or more cases underneath, tying the stack together. Column stacking is stronger in compression, which matters for heavy or fragile cases in racking; interlocking is more stable in transit. Mixed patterns like the ones this tool finds make interlocking possible even when the case does not divide the pallet evenly.
How do I factor pallet overhang into a Ti-Hi calculation?
Enter the overhang you allow on each side, and it is added to the usable deck length and width before the layer is packed. Most shippers and retailers prohibit overhang, because cases hanging past the deck edge take crushing damage and weaken the stack, so the default is zero. Underhang — cases stopping short of the edge — is safe and is what the layer diagram usually shows.
How many cases fit on a pallet?
Multiply Ti by Hi. For example, 12 x 10 x 10 in cases on a 48 x 40 GMA pallet with a 60 in maximum load height fit 16 per layer and 5 layers high, for 80 cases — unless the weight limit stops the stack first, which this calculator checks and reports.
Is any of my data uploaded or stored?
No. The calculator runs entirely as a small script inside this page; the numbers you type never leave your browser, and there is no upload, no API call and no analytics here. That is enforced rather than promised: this site’s test suite scans the shipped HTML for every browser API capable of sending data off the page and fails the build if it finds one.
