Warehouse managers can use this online calculator to find out how many pallets can fit on a trailer for transport. Enter the length and width of the pallet or load, the side spacing you anticipate and change the dimensions of the over the road trailer you intend to use (or stay with the default dimensions).
To begin, fill in the gray boxes and click calculate.
This is assuming the product is coming in or going out unpalletized.
This calculator checks cubic volume of a pallet against the available cubic volume of the ISO container.
