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

36 cartons of 300 × 300 × 300 mm fit on a Standard pallet (1200 × 1000 mm): 12 cartons per layer, 3 layers within a 1200 mm stack height including the pallet.

Best pattern: Split-Row Interlock

Cartons sit lengthwise, long side along the pallet's length. 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 300 × 300 mm leave a strip of deck unused, and that strip is wide enough for cartons turned 90°. Splitting the layer this way fits 12 per layer and lets alternating layers mirror and interlock.

Pattern comparison

Several layouts tie at 12 of these 300 × 300 mm cartons per layer (grid 12, split-row 12, 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 90% of the deck footprint.

No better-interlocking layout exists for this carton on this deck within the computed patterns. Stack it column-aligned, corners over corners, and rely on stretch wrap or strapping for lateral stability.

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.
