ISO 6780 defines six international flat pallet dimensions for global trade.
Detailed Definition
ISO 6780, Flat pallets for intercontinental materials handling, sets principal dimensions and tolerances for flat pallets. It lists six footprints in millimeters: 1200 x 800, 1200 x 1000, 1219 x 1016 (the US 48 x 40 inch pallet), 1165 x 1165, 1100 x 1100 and 1067 x 1067. The 1200 x 800 size is the EUR/EPAL footprint, 1165 x 1165 is associated with Australia, and 1100 x 1100 is common in parts of Asia.
Why the standard lists six footprints
By the time ISO set international pallet sizes, regional sizes were already built into racking, trucks, containers and retail systems. Rather than pick one size, the standard recognizes six that are widely used. Unit conversion matters too: 48 x 40 inches is 1219 x 1016 mm, which is close to but not the same as 1200 x 1000 mm. The two do not substitute for each other in racking with tight clearances or in automated handling systems.
Tolerances matter as much as nominal sizes. A pallet a few millimeters oversize can bind in a dispenser, conveyor or automated storage system even though it carries the same size name, so automated sites often set tighter tolerances in their own specifications.
Choosing a footprint for export and mixed fleets
- Match the destination's dominant size when goods will be stored or reworked there.
- Plan container loading patterns before committing, since each footprint fits container widths differently.
- Confirm rack beam depth and fork entry for automated warehouses.
- Specify strength separately: ISO 6780 sets dimensions only, while performance comes from design and from test standards such as ISO 8611 or ASTM D1185.

Frequently Asked Questions
Is the 48 x 40 pallet an ISO standard size?
Yes. ISO 6780 includes 1219 x 1016 mm, which is the 48 x 40 inch pallet used widely in North American grocery and consumer goods distribution. Being on the list only confirms the footprint is recognized internationally. It does not set materials, number of boards, entry type or strength, which come from customer specifications, industry conventions such as GMA-style designs, and test standards.
Does ISO 6780 say how strong a pallet must be?
No. ISO 6780 covers principal dimensions and tolerances only. Load capacity and performance are addressed by test method standards such as ISO 8611 and, in the US, ASTM D1185, along with design tools such as the NWPCA Pallet Design System. A pallet can match an ISO footprint exactly and still be too weak for a given load or rack span, so specify capacity separately.
