Pallet Ti Hi Calculator: Estimate Pallets Needed

A pallet ti hi calculator works out how many product layers fit on a pallet and the total number of units, or the total pallet height, from the cases per layer, layer count, and case dimensions. Enter the package and pallet measurements plus your stacking plan to get a practical estimate; the result depends on how your supplier defines a case and whether pallet height is included.

Formula

The first result is the total count of individual units on one pallet:

Total units = cases per layer × number of layers × units per case

• Cases per layer (c): the number of cases arranged on a single pallet layer, in cases.
• Number of layers (h): the number of case layers stacked vertically, in layers.
• Units per case (u): individual items packed in each case, in units per case.

The second result estimates loaded height: Loaded height = pallet height + (number of layers × case height). Pallet height and case height must use the same unit. This specification uses inches; to work in centimetres, convert both measurements first or use a calculator configured for centimetres. The total-units calculation is unaffected by length units.

Worked Example

With the calculator’s default inputs—10 cases per layer, 5 layers, 12 units per case, 8-inch cases, and a 6-inch pallet—the arithmetic is:

1. Cases on the pallet = 10 cases per layer × 5 layers = 50 cases.
2. Total units = 50 cases × 12 units per case = 600 units.
3. Case stack height = 5 layers × 8 inches = 40 inches.
4. Loaded height = 6-inch pallet + 40-inch case stack = 46 inches, or about 116.8 cm.

The first, headline result is 600 units. The height is a separate estimate and assumes the cases are stacked directly without extra sheets, gaps, or other materials.

What “Ti Hi” Means

“Ti” and “hi” are warehouse shorthand for the two dimensions of a pallet pattern. Ti is the number of cases placed on each layer; hi is the number of layers stacked. A ti-hi listing such as 10 × 5 therefore means 10 cases per layer and 5 layers, or 50 cases on the pallet.

That figure counts cases, not necessarily the sellable items inside them. If each case contains 12 bottles, for example, 50 cases represent 600 bottles. The calculator makes this distinction explicit by multiplying cases per layer and layers by units per case.

How to Find the Inputs

Use the product’s packaging specification, pallet label, or information from the supplier where available. The layer count and cases per layer can vary with the case footprint, pallet dimensions, orientation, and stacking pattern. Do not assume a ti-hi pattern from another product or pallet is suitable for yours.

• Cases per layer: count the cases in one complete layer of the intended pattern. If the pattern alternates by layer, use the actual count for each layer rather than assuming every layer matches.
• Number of layers: use the planned stack height, not a guess based only on how many cases are available. Confirm any stacking constraints with the product or shipping specification.
• Units per case: check the case pack quantity. A mixed case may not have the same quantity as a single-product case.
• Case and pallet height: measure in the same units. Include the pallet only if you need the overall loaded height.

For an irregular or mixed-layer pattern, calculate each layer separately: add the case counts for all layers, then multiply by units per case if every case has the same pack quantity. If case pack quantities differ, total the units in each group rather than multiplying by one shared number.

When the Estimate Is Useful

A ti-hi calculation is useful for checking pallet quantities, comparing a planned stack with a product specification, or estimating how many individual items a full pallet contains. It can also help with inventory arithmetic: if a shipment has 8 pallets of 600 units each, the estimated total is 4,800 units, provided all pallets use the same configuration and are full.

Loaded height can help with basic space planning, but it is only the vertical measurement. It does not establish whether a pallet will fit a particular vehicle, doorway, rack, or storage location. Those checks may also depend on load overhang, wrapping, top sheets, uneven surfaces, and handling requirements.

Common Errors and Limits

The most common mistake is treating ti-hi as the number of individual products. It normally describes cases per layer and layers; convert to units only after multiplying by the case pack. Another frequent error is mixing inches and centimetres in the height formula. For example, adding a 6-inch pallet to a 20-centimetre case stack gives a meaningless total unless one measurement is converted.

Also distinguish the height of the cases from the height of the entire loaded pallet. If the pallet is already included in a supplier’s stated overall height, do not add it a second time. The simple formula assumes identical cases, equal layer heights, and a uniform stack. It does not determine whether the stack is stable, safe to handle, or suitable for a particular load. Follow applicable product, pallet, and workplace instructions for stacking and transport; a numerical estimate is not a safety assessment.

Finally, the calculation assumes all planned positions are filled. If a pallet is incomplete, use the actual case count rather than the maximum pattern. Rounding is unnecessary for these results when inputs are whole counts, but an estimated or partial layer should not be rounded up and presented as a confirmed quantity.

Frequently Asked Questions

What does ti-hi mean on a pallet label?
Ti is the number of cases in one layer, and hi is the number of layers. Multiply them to find the total cases on a full pallet when every layer has the same case count.

How do I calculate cases per pallet?
Multiply cases per layer by the number of layers. For example, a 10 × 5 pattern holds 50 cases, assuming all five layers contain 10 cases.

How do I calculate individual items per pallet?
Multiply cases per layer × layers × items per case. A 10 × 5 pallet with 12 items in each case holds 600 items.

Does ti-hi include the pallet itself?
No. Ti-hi describes the case pattern, not pallet height. Add the pallet’s height separately when estimating the total loaded height.

Can every layer have a different number of cases?
Yes, but a single cases-per-layer input will not represent an uneven pattern accurately. Add the case count from each layer, then convert cases to individual units as needed.

Is a ti-hi calculation enough to confirm a pallet is safe to stack?
No. It estimates quantity and, if entered, height. It does not assess load stability, pallet condition, weight limits, or suitability for storage and transport; follow relevant handling specifications.
