How many 450 × 350 × 300 mm cartons fit on a Standard pallet?

18 cartons of 450 × 350 × 300 mm fit on a Standard pallet (1200 × 1000 mm): 6 cartons per layer, 3 layers within a 1200 mm stack height including the pallet.

Best pattern: Split-Row Interlock

Cartons sit in mixed orientations, the pattern combines both directions. Most rows face one way and the remaining strip is turned 90°, so layers can be mirrored and lock together like brickwork.

Why this pattern here: Straight rows of 450 × 350 mm leave a strip of deck unused, and that strip is wide enough for cartons turned 90°. Splitting the layer this way fits 6 per layer and lets alternating layers mirror and interlock.

Several layouts tie at 6 of these 450 × 350 mm cartons per layer (grid 6, split-row 6, pinwheel 4). The tool selects the Split-Row Interlock pattern because when counts are equal an interlocking layout beats a plain grid on load stability. 3 layers reach 1050 mm including the 150 mm pallet deck, at 78.8% of the deck footprint.

Prefer stability? The pinwheel alternative

The maximum-load layout above leaves 1 of its 6 cartons per layer stacked in unbonded columns, a carton bonded to only one below rides the stack as a free tower held by wrap alone. If stability matters more than count: a pinwheel fits 4 of these 450 × 350 mm cartons per layer, 2 fewer, and every carton rests across at least two cartons below, so the layers interlock like brickwork. 12 cartons per pallet at 1050 mm, using 52.5% of the deck.

These figures assume the height limit binds at 1200 mm. Weight is not shown here because it depends on the actual carton weight, the interactive calculator also enforces a max payload per pallet.
