01The five and a half inches that cost you a container
The 48x40 GMA pallet exists because two of them fit side by side across a 53-foot trailer's 98 to 100 inch interior. That is the entire reason. It is a brilliant fit for domestic freight and it was never designed with an ocean container in mind.
A standard 40-foot container has an internal width of roughly 92.5 inches. Two 48-inch pallets occupy 96. They do not fit. So loads get turned, staggered, or shipped one wide with a gap, and the container leaves with air in it.
| Footprint | Two across | Width used | Waste |
|---|---|---|---|
| 48 x 40 in | Does not fit | 96 in | — |
| 45 x 45 in | Fits | 90 in | 2.5 in |
| 44 x 44 in | Fits | 88 in | 4.5 in |
| 40 x 48 in | Fits | 80 in | 12.5 in |
| 1200 x 800 mm | Fits | 63 in (two short-side) | Depends on orientation |
02What the cube is actually worth
This is where the argument gets settled, because it is not a pallet cost question. It is a container cost question, and containers cost far more than pallets.
Suppose you ship 200 containers a year and a footprint change gets you 10% more product into each. You now need 182 containers to move the same volume. At even a modest $2,800 all-in per container, that is roughly $50,000 a year — against a pallet premium that might be $6 a unit on 8,000 pallets, or $48,000 spread over the same period. And that is the pessimistic version, because the pallet premium falls on repeat orders while the freight saving does not.

03The costs that belong in the same calculation
I want to be even-handed here, because we sell custom pallets and it would be easy to stop at the paragraph above.
- No recovery market. Nobody else uses a 45x45. At end of life it is worth fibre value, not pallet value — roughly a tenth.
- No emergency supply. There is no yard in the country holding 300 of your size. Lead time is build time, always.
- Repair complexity. Odd boards mean odd stock, and repairs cost more and take longer.
- Receiver friction. Your customer's racking and dock plate were designed around a standard. An odd pallet can create a problem at their end that becomes yours.
- Lumber yield. An odd width may waste a rip that a standard width does not, and that waste is in every unit forever.
04The cheaper alternatives to check first
- Change the case tile. Sometimes the product pattern, not the pallet, is what wastes the width.
- Use slip sheets. A 0.03-inch sheet replaces a 5-inch deck. On push-pull lanes it recovers a whole tier of height per stack — but both ends need the attachment.
- Rotate the load. A 40x48 orientation fits where a 48x40 does not, at the cost of some racked capacity. Check the rack first.
- Ship one-wide with a wider product. Occasionally the answer is to redesign the case, not the pallet.
We go through these before quoting a custom build, because roughly a third of container-cube enquiries resolve into one of them. More on the trade-offs in custom and odd sizes.
