What is Ti Hi? Complete Guide
Ti Hi meaning in shipping and warehousing
Ti stands for Tier — the number of cartons or cases in a single layer on a pallet. Hi stands for High — the number of layers stacked on the pallet. Together, Ti × Hi gives you the total number of units per pallet.
Example: if you can fit 10 cases per layer and stack 5 layers high, the Ti Hi is 10 × 5 and the pallet holds 50 cases.
How to calculate Ti Hi manually
To calculate Ti (units per layer):
- Divide pallet length by carton length → columns
- Divide pallet width by carton width → rows
- Columns × rows = Ti
- Try rotated orientation (swap L and W) and use whichever gives more units
To calculate Hi (layers):
- Take your maximum pallet height (e.g. 60")
- Subtract pallet board height (typically 5.5")
- Divide by carton height → Hi
Ti Hi requirements for Walmart, Amazon, and Target
Major retailers require vendors to print the Ti Hi on pallet labels. Mismatches between the declared Ti Hi and the actual pallet configuration result in chargebacks.
- Walmart SQEP: Ti Hi must be declared on the GS1-128 pallet label. Maximum height 60" including pallet.
- Amazon FBA: Maximum pallet height 72" for non-stackable, 48" for stackable. Ti Hi declared in Seller Central.
- Target: Follows GS1 standards. Ti Hi printed on licence plate label.
Standard pallet sizes for Ti Hi calculation
| Pallet Type | Size (L×W) | Used By |
|---|---|---|
| GMA Standard | 48×40" | Walmart, Target, most US retail |
| Square | 48×48" | Industrial, drums, heavy goods |
| EUR/EPAL | 47×31" | European supply chains |
Ti-Hi Calculator — Frequently Asked Questions
What does Ti-Hi mean?
Ti-Hi (also written Ti × Hi or "tie-high") is a two-number pallet pattern. Ti is the number of cartons in a single layer — the "tier" — and Hi is the number of layers stacked on the pallet — the "high." Multiply them (Ti × Hi) to get total cartons per pallet. A Ti of 10 and a Hi of 5 means 50 cartons per pallet.
How do you calculate Ti-Hi?
Find how many cartons fit in one layer by fitting the carton footprint into the pallet footprint (that's your Ti), then divide the maximum allowed stack height by the carton height to get the number of layers (your Hi). The calculator above does both automatically and tests rotated carton orientations to maximize floor use, so you don't have to work the geometry by hand.
What is a Ti-Hi pallet pattern?
It's the standardized way a shipper builds every pallet of a given product — the same cartons per layer and the same number of layers each time. A consistent pattern keeps pallets stable, makes case counts predictable at receiving, and ensures the load fits the retailer's racking and trailers.
What's a good Ti-Hi for a 48×40 pallet?
It depends on your carton size, but for a standard GMA 48×40" pallet, common patterns fall between Ti 8–12 and Hi 4–6 — roughly 40–60 cartons per pallet at a 50–60" stack height. Enter your real carton dimensions above for an exact figure for your product.
What's the difference between Ti and Hi?
Ti is horizontal — cartons per layer — and Hi is vertical — the number of layers. "Ti" comes from "tier" and "Hi" from "high." Together the two numbers describe an entire pallet build at a glance.
Why do retailers like Walmart and Amazon specify a required Ti-Hi?
A fixed Ti-Hi guarantees pallet stability, full trailer cube utilization, and accurate case counts. Missing the required pattern can trigger OTIF or SQEP chargebacks, which is why big-box retailers publish exact Ti-Hi requirements per item.
