How Many Boxes Fit on a Pallet?

Start with pallet and carton dimensions

Use the usable pallet length and width together with the external length and width of the packed carton. All measurements should use the same unit.

Calculate cartons in one orientation

Divide pallet length by carton length and pallet width by carton width. Round each result down because partial cartons cannot occupy a full position.

Check the rotated orientation

Rotating the cartons by 90 degrees can sometimes fit more units. Repeat the calculation with carton length and width reversed and compare the two results.

Calculate total cartons

Once the number of cartons per layer is known, multiply it by the intended number of layers.

Why simple pallet calculations are approximate

• Mixed-orientation patterns can sometimes improve space utilization.
• Carton strength can limit the number of vertical layers.
• Maximum pallet height can restrict stacking.
• Weight limits may be reached before the geometric capacity is filled.
• Some operations prohibit or restrict pallet overhang.

Pallet weight matters too

A layout that fits geometrically may still exceed a pallet, warehouse-rack, vehicle or transport weight limit. Total loaded weight should therefore be checked separately.
