How many 350 × 350 × 350 mm cartons fit on a Standard pallet?
18 cartons of 350 × 350 × 350 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 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 350 × 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.
Pattern comparison
| Pattern | Cartons per layer |
|---|---|
| Grid | 6 |
| Split-Row InterlockBest | 6 |
| Pinwheel | 4 |
Several layouts tie at 6 of these 350 × 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 1200 mm including the 150 mm pallet deck, at 61.3% of the deck footprint.
Prefer stability? The pinwheel alternative
The maximum-load layout above leaves 6 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 350 × 350 mm cartons per layer, 2 fewer, and all but 4 cartons per layer rest across at least two cartons below and interlock like brickwork. 12 cartons per pallet at 1200 mm, using 40.8% 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.
