TI-HI explained
TI-HI pallet calculator
TI describes cases per layer. HI describes complete layers high. Multiply them to estimate cases per pallet, then check weight and stability.

TI comes from the pallet footprint and the carton footprint. The calculation must use complete rows and columns rather than area alone. Turning the upright carton 90 degrees can change the result.
HI is the vertical layer count.
If the total allowed height includes the pallet, subtract the pallet base first. Divide the remaining load height by the upright carton height and keep only complete layers.
TI × HI gives the geometric pallet quantity.
For a 48 × 40 inch pallet with 16 × 12 × 12 inch cartons, a uniform layout gives 9 TI. The planner combines upright orientations to fit 10 TI without gaps or edge clearance. With 66 inches available above the pallet, five complete layers fit: 5 HI. The two geometric estimates are 9 × 5 = 45 cartons for the uniform layout and 10 × 5 = 50 cartons for the combined layout. Confirm that the chosen pattern is suitable for the real load.
Why the final number can be lower.
TI-HI describes geometry. It does not automatically prove payload, compression strength, stability, overhang compliance or safe handling. Add weight and strength information when available and confirm the completed load.
Common questions
Quick answers before you calculate.
What does TI-HI mean?
TI is the number of cases in one pallet layer. HI is the number of complete layers stacked vertically.
How do I calculate cases per pallet from TI-HI?
Multiply TI by HI. For example, 9 TI × 5 HI equals 45 cases per pallet before operational limits are applied.
Does TI-HI include the pallet height?
TI does not use height. For HI, subtract pallet base height if your maximum height includes the pallet, then divide the remaining load height by carton height.
