Length First, Then Width, Convention Matters
The universal convention states pallet dimensions as length by width, and getting the order right prevents costly confusion. For a stringer pallet, the length is the direction of the stringers, and the width is across the deck boards, so a 48×40 has 48-inch stringers and 40-inch deck boards. Stating a 48×40 as a 40×48 by accident can send you a rotated or genuinely different pallet, so always confirm which number is length before you order.
This matters because a 48×40 and a 40×48 describe pallets that behave differently in racking, on conveyors, and in a trailer, even though the numbers look similar. Suppliers work to the convention, so a measurement stated in the wrong order can produce exactly the wrong pallet. Whenever there is any ambiguity, specify explicitly which dimension is the stringer or fork-entry direction to remove all doubt.
The Three Core Dimensions
Measure overall length and width to the outermost edges of the deck boards, using a rigid tape and measuring the actual pallet rather than assuming the nominal size, because used pallets can vary slightly. Then measure overall height from the floor to the top of the top deck boards, which for a standard GMA pallet is around five and a half to six inches. Height matters for racking clearance, trailer stacking, and equipment fit, so do not skip it.
Record these to a sensible precision, typically the nearest quarter or eighth of an inch, and note whether you are measuring nominal or actual. A pallet described as 48×40 may actually measure a fraction over or under, and for tight applications like automation that fraction matters. For general reorders the nominal size suffices, but always measure a real sample rather than trusting a label, especially when reordering to match existing stock.
Deck Board Thickness and Count
Overall dimensions are not enough to reorder a matching pallet, because two 48×40s can differ substantially in deck board thickness and count. Measure the thickness of the deck boards, commonly around five-eighths of an inch, and count the top and bottom boards, because these drive load capacity and surface coverage. A replacement pallet with the same footprint but fewer or thinner boards may not support your product or perform in racking as the original did.
Note the spacing pattern too, whether boards are spaced with gaps or butted tightly, and the width of individual boards. These details define how the deck supports a load and whether small-footprint items will sag between gaps. Capturing the full board specification, not just the footprint, is what makes a reorder truly match rather than merely share the same outside dimensions.
Stringer or Block Dimensions and Entry
Record the construction and entry type, because a 48×40 stringer pallet and a 48×40 block pallet are different products that happen to share a footprint. For stringer pallets, note whether the stringers are notched for partial four-way entry and measure the stringer height, which sets the fork opening. For block pallets, note the block dimensions. This construction detail is essential for the pallet to work with your forklifts and pallet jacks as expected.
Measure the fork entry opening height, the gap between the top and bottom decks that a fork tine enters. Standard equipment expects a certain opening, and a reorder with a different stringer or block height can foul your forks or jacks. Confirming entry type and opening dimensions ensures the reordered pallet handles identically to what your operation is already tooled for.
Common Measurement Mistakes
The frequent errors are predictable: reversing length and width, measuring a single worn sample and assuming it represents the batch, ignoring board thickness, and forgetting height. Each produces a reorder that looks close on paper but fails in practice. Measuring several sample pallets and reconciling them guards against basing an order on one atypical unit, and using a written spec sheet rather than relying on memory removes the transcription errors that creep in between the dock and the purchase order.
Another trap is trusting a stamped or printed size on the pallet itself, which may reflect the original manufacturer's nominal spec rather than the actual current dimensions of a used, possibly repaired unit. Always verify by measuring. A five-minute measurement of a real sample is cheap insurance against a whole truckload of the wrong pallet arriving at your dock and stopping the flow.
Documenting the Spec for Reorders
Turn your measurements into a written spec sheet you attach to every reorder: length by width by height, construction type, entry type, deck board count and thickness, spacing, and grade. This single document removes ambiguity between you and the supplier and makes every future reorder a reference rather than a fresh guess. It also lets a supplier match your pallet exactly even if the person placing the order changes.
Keep the spec sheet with a photo and, ideally, a physical sample or the original spec on file. When you shop a new supplier or reorder after a gap, the documented spec ensures you get the same pallet you validated before, not a lookalike that fails on the details. Good measurement is only half the job; capturing it in a reusable spec is what prevents the mistake from ever recurring.
Key takeaways
- State length by width per convention; length follows the stringer direction.
- Measure a real sample for overall length, width, and height, not the label.
- Capture deck board count, thickness, and spacing, not just the footprint.
- Record construction and fork entry opening so handling matches your equipment.
- Document everything in a reusable spec sheet attached to every reorder.
