How many 12 × 12 × 12 in cartons fit on a US 48×40 pallet?

27 cartons of 12 × 12 × 12 in (305 × 305 × 305 mm) fit on a US 48×40 pallet, 48 × 40 in (1219 × 1016 mm): 9 cartons per layer, 3 layers within a 47.2 in (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 12 × 12 in leave a strip of deck unused, and that strip is wide enough for cartons turned 90°. Splitting the layer this way fits 9 per layer and lets alternating layers mirror and interlock.

Pattern comparison

Several layouts tie at 9 of these 12 × 12 in cartons per layer (grid 9, split-row 9, 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 41.7 in (1060 mm) including the 5.7 in (146 mm) pallet deck, at 67.5% 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 47.2 in (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.
