How to use this calculator
- Enter or choose layers of cartons.
- Enter or choose carton height (outside).
- Enter or choose pallet height.
- Enter or choose slip sheets, tier sheets and top cap.
- Enter or choose height limit (including pallet).
- The loaded pallet height updates as you type. Use Copy result or Share to keep it.
Method
Height = Layers × Carton height + Pallet height + Sheets; Max layers = ⌊(Limit − Pallet − Sheets) ÷ Carton height⌋
- Sheets
- total thickness of slip sheets, tier sheets and caps
Worked example
- Height = 5 × 250 + 144 = 1394 mm.
- Headroom = 1800 − 1394 = 406 mm.
- Max layers = ⌊(1800 − 144) ÷ 250⌋ = ⌊6.62⌋ = 6.
Five 250 mm layers on a 144 mm pallet stand 1394 mm tall; a sixth layer would still fit under 1800 mm.
What the result means
If you have headroom for another layer, check the pallet weight limit and the bottom carton’s compression strength before adding it.
Assumptions and limits
- All layers are the same height.
- Cartons compress and bulge under load, so the real height can differ by several millimetres.
Questions
Does the limit include the pallet?
Here, yes. Racking and vehicle limits are usually for the whole unit load from the floor.
How many inches is 1800 mm?
1800 ÷ 25.4 = 70.9 inches.
