How many 24 × 18 × 18 in cartons fit on a US 48×40 pallet?

6 cartons of 24 × 18 × 18 in (610 × 457 × 457 mm) fit on a US 48×40 pallet, 48 × 40 in (1219 × 1016 mm): 3 cartons per layer, 2 layers within a 47.2 in (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 24 × 18 in leave a strip of deck unused, and that strip is wide enough for cartons turned 90°. Splitting the layer this way fits 3 per layer and lets alternating layers mirror and interlock.

Pattern comparison

Here the split-row interlock fits 3 of these 24 × 18 in cartons per layer, where a plain grid manages 2. Turning one strip of the layer 90° covers 67.5% of the deck footprint, and because alternating layers are mirrored, the load interlocks like brickwork. 2 layers reach 41.7 in (1060 mm) including the 5.7 in (146 mm) pallet deck.

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.
