How to Calculate Cases per Pallet (Ti-Hi)
Cases per pallet = Ti x Hi, capped by the weight limit. Three steps:
- Ti: the most cases that fit in one layer on the deck, trying the case both ways round.
- Hi:
floor((max load height - pallet height) / case height) - Weight cap:
floor((max gross weight - pallet weight) / case weight). Cases per pallet is the smaller of Ti x Hi and the weight cap.
Worked example: US 48 x 40 pallet
Case 12 x 10 x 10 in, 10 lb; pallet 6 in high, 40 lb; limits 60 in and 2,500 lbTi = (48 / 12) x (40 / 10) = 4 x 4 = 16Hi = floor((60 - 6) / 10) = 5Weight cap = floor((2,500 - 40) / 10) = 246Cases per pallet = min(16 x 5, 246) = 80
16 x 5 = 80 cases, 56 in tall and 840 lb with the pallet. Height is the limit.
Worked example: Euro pallet 1200 x 800 mm
Case 400 x 300 x 250 mm, 8 kg; pallet 144 mm high, 25 kg; limit 1,800 mmTi: 300 mm along the 1200 side (4) x 400 mm along the 800 side (2) = 8Hi = floor((1,800 - 144) / 250) = 6Cases per pallet = 8 x 6 = 48, gross weight 25 + 48 x 8 = 409 kg
48 cases per Euro pallet, with the deck fully covered.
Standard Pallet Sizes
The six sizes in ISO 6780 cover most pallets in use. The calculator has presets for the first three; enter any other size as a custom pallet.
| Pallet | Millimetres | Inches | Where |
|---|---|---|---|
| GMA pallet | 1219 x 1016 | 48 x 40 | United States |
| UK standard | 1200 x 1000 | 47.2 x 39.4 | UK, Europe |
| Euro pallet (EUR 1) | 1200 x 800 | 47.2 x 31.5 | Europe |
| Australian | 1165 x 1165 | 45.9 x 45.9 | Australia |
| ISO square | 1067 x 1067 | 42 x 42 | North America, Europe, Asia |
| Asian | 1100 x 1100 | 43.3 x 43.3 | Asia |
Height and weight limits depend on the carrier, the pallet network and your customer's racking, so check them before you build a pallet plan. Retail distribution centres often publish a maximum Ti-Hi and load height in their routing guide.
From Pallet Plan to Shipment
Once you know the cases per pallet, work out the shipment volume with the CBM calculator (container fit and volumetric weight) and the LTL class with the freight class calculator. To put the freight into your unit cost, use the landed cost calculator.
