Before you ship: the routing guide attached to your purchase order is the authority, and requirements vary by facility and change without much notice. Treat the figures below as the commonly published baseline for planning, then confirm against your current guide.
Costco's pallet rules are shaped by one thing: the pallet you ship is the pallet the member shops from. There is no unpacking step. Product moves through a no-touch cross-dock and onto the sales floor as-is, which is why the height limit is far tighter than any other major retailer and why the load has to survive clamp trucks and double-stacking without deforming.
That roughly 58-inch ceiling — including about 5.5 inches of pallet — leaves only around 52 inches of usable product height. Compare that with Walmart at 72 in or Target at up to 84 in and the design implication is stark: a case size that works everywhere else may not yield a viable layer count for Costco.
The height limit interacts with case height to produce hard layer counts. Assuming about 52 in of usable product height:
| Case height | Layers that fit | Wasted height |
|---|---|---|
| 10 in | 5 | 2 in |
| 11 in | 4 | 8 in |
| 12 in | 4 | 4 in |
| 13 in | 4 | 0 in |
| 14 in | 3 | 10 in |
Look at the 10 in to 11 in step: one extra inch of case height costs you an entire layer, roughly 20% of the pallet. This is why Costco case design usually starts from the height limit and works backwards, rather than starting from the product. Run your own numbers with the TI-HI calculator.
| Requirement | Commonly published rule |
|---|---|
| Footprint | 48 × 40 in GMA standard; actual load footprint often specified nearer 47 × 39 in for stability |
| Maximum height | Around 58 in including the pallet |
| Overhang | Minimal — commonly no more than 1 in per side, and many buyers expect zero |
| Structure | Must be stable enough to double-stack and to withstand clamp-truck pressure |
| Presentation | Floor-ready — the pallet goes to the sales floor without repacking |
| Labels | GS1-128 case labels, positioned for no-touch scanning |
The 47 × 39 in load footprint is deliberate. Building the load fractionally inside the pallet edge means that even with normal shifting in transit, nothing protrudes past 48 × 40 — see why overhang matters.
Costco item packaging is judged as retail display, not as transit protection. In practice that means:
| Expectation | What it implies |
|---|---|
| Shipper displays | Cases often double as the display tray — printed, die-cut, customer-facing |
| No repacking labour | Anything a warehouse worker would have to open, sort or restack is a failure |
| Structural integrity | The bottom layer carries the full stack plus a second pallet above it |
| Consistent facing | Product orientation is part of the spec, not a nicety |
This is the practical difference between Costco and a conventional DC retailer: elsewhere the pallet is a transport unit, here it is a merchandising unit that also has to survive transport.
Commonly published guidance is around 58 inches including the pallet, which is roughly 52 inches of usable product height once the pallet deck is accounted for. This is materially lower than Walmart, Target or Amazon FBA, and it is the constraint most Costco case designs are built around.
Very little. Guidance commonly permits no more than about 1 inch per side, and many buyers expect none at all. Loads are often built to a 47 × 39 in footprint so that normal shifting in transit still keeps the load inside the 48 × 40 pallet edge.
Because the pallet goes straight to the sales floor. Costco runs a no-touch cross-dock model with no repacking step, so the pallet is simultaneously a shipping unit and a retail display. It has to fit the warehouse ceiling and shopping sightlines, survive double-stacking, and look right to a member.
That the pallet arriving at the club can be placed on the sales floor without any unpacking, sorting or restacking. Cases usually double as printed display trays, product facing is specified, and the bottom layer must carry the full load plus whatever is stacked above it.
The 48 × 40 in GMA standard footprint. See the GMA pallet page for construction details and the pallet sizes comparison for how it relates to other standards.
It depends entirely on case height against roughly 52 inches of usable height. A 10 in case gives five layers; an 11 in case gives only four. One inch of case height can cost a full layer, so it is worth optimising deliberately.
