Confusing it with the Australian standard
Australia's standard is 1165 x 1165 mm, about 45.9 inches square. The 42x42 is a North American size.
FixConfirm the destination footprint before assuming it transfers.
01Where the square footprint wins
Rectangular pallets carry an assumption: that someone knows which way round they go. On a conveyor line, a pallet fed the wrong way jams. In a rack designed for a 48-inch depth, a 40-inch-deep presentation loses beam contact. Square footprints delete that entire class of problem.
- Telecom. Cable reels are round; a square deck wastes less and supports the reel flange evenly.
- Paint and coatings. Pails tile onto a square face in a 4x4 or 3x3 pattern with minimal void.
- Adhesives and chemicals. Drum ring patterns are radial, so a square base is the natural fit.
- Automated lines. No orientation logic, no jams, no vision system needed to check rotation.
02Specification
| Component | Quantity | Nominal dimensions |
|---|---|---|
| Top deck boards | 6–7 | 42 x 5.5 x 0.625 in |
| Stringers | 3 | 42 x 3.5 x 1.5 in |
| Bottom deck boards | 3 | 42 x 5.5 x 0.625 in |
| Notch | 2 per stringer | 9 x 1.5 in |
| Overall height | — | 5.0–5.5 in |
Because the stringer length equals the deck board length, a 42x42 can be built with the stringers on either axis without changing the parts list — which makes it unusually cheap to build in a mixed shop and unusually easy to repair from general board stock.
03Availability and what it costs
42x42 is a regular but not continuous item in our yard. Recovery volume tracks the industries that use it, so supply arrives in batches rather than a steady stream. If you need weekly volume, tell us — we will build the recovery route around it rather than promising stock we do not hold.

Rules of thumb
Carry these in your head
- 01Square means there is no wrong way round — a real advantage on automated lines.
- 02Stringer length equals deck board length, which makes it cheap to build and easy to repair.
- 03Availability is batch, not continuous. Plan ahead.
Before you order
The decisions we will ask you to make
A quote turnaround is limited by how many follow-up questions we have to ask. Working through this list removes nearly all of them.
- 01
Is the product round or square?
Cable reels, pails and drum ring patterns waste less on a square deck than on a rectangle.
- 02
Does orientation matter?
Square footprints delete an entire class of conveyor and rack presentation problems.
- 03
Beam depth
Racking configured for a 40-inch depth leaves a 42-inch pallet overhanging the rear beam by two inches.
- 04
Volume commitment
42x42 is batch stock, not continuous. Ask before planning weekly volume around it.
What goes wrong
Expensive mistakes, and the fix for each
Every one of these turns up in ordinary purchase orders. All of them cost multiples of whatever they appeared to save.
02
Choosing it for general dry freight
Two 42-inch pallets waste 14–16 inches of trailer width. That is the price of squareness.
FixUse 48x40 for general freight; reserve 42x42 for round product and orientation-sensitive automation.
Against our interest
When this is the wrong answer
We would rather lose the order than sell you the wrong thing. These are the situations where this page is not what you need.
- 01
General dry freight
Two 42-inch pallets waste 14–16 inches of trailer width. That is the price of squareness, and it is why 42x42 never displaced the 48x40.
- 02
Racking configured for 40-inch depth
A 42-inch pallet overhangs the rear beam by two inches. Tolerable for light loads, a bad idea for heavy ones.
- 03
Programmes needing continuous availability
This is batch stock, not continuous. Recovery volume tracks the industries that use it, so supply arrives in waves.
What moves the price
Cost drivers, and roughly how much each one is worth
A quote is not a list price with a discount applied. It is these variables added up, which is why two quotes for nominally the same thing can differ so widely.
| Driver | What it is | Rough effect |
|---|---|---|
| Batch availability | Recovery arrives in waves rather than a steady stream, so timing matters more than for 48x40. | $9–$15.50 depending on position |
| Build simplicity | Stringer length equals deck board length, so it is unusually cheap to build in a mixed shop. | New builds price closer to 48x40 than the volume suggests |
| Freight inefficiency | Two across uses 84 in of a 98–100 in trailer. | Higher cost per pallet-foot |
| Repair simplicity | One board length covers every component, so repair stock is easier to hold. | Lower repair cost |
Due diligence
Questions to ask any supplier
Us included. The answers tell you a great deal, and so does how quickly they arrive — a yard that has these documents ready is a yard that has thought about them.
- 01
“What is your current batch position, and when is the next expected?”
- 02
“What is your rack beam spacing — will a 42-inch depth overhang?”
- 03
“Is orientation a problem on our conveyors today?”
- 04
“Would a 48x40 with a different case tile solve the same problem?”
The rulebook
Standards and authorities that actually apply
Plenty of pallet marketing invokes standards loosely. These are the real documents behind this subject, and what each one does and does not cover.
- ANSI MH1
Lists 42x42 among recognised North American footprints.
- ISO 6780
Does not include 42x42. The nearest international square footprint is 1100x1100 mm, used across Asia.
- Australian standard 1165x1165 mm
Frequently confused with 42x42. It is about 45.9 inches square and is not interchangeable.
Confirm the destination footprint before assuming it transfers.
Vocabulary
The terms used on this page
Defined the way the trade uses them, not the way a dictionary would.
- Four-way entryalso: Partial four-way
- Access from all four sides. True four-way requires block construction; a notched stringer pallet is only four-way for forklifts, not for pallet jacks.
- Notch
- The cut-out in a stringer allowing fork entry from the side, typically 9 inches long by 1.5 inches deep. Also the most common point of structural failure.
- Racked load
- The weight a pallet carries spanning two rack beams with nothing beneath the centre. Always the lowest of the three load ratings.
- Deck coverage
- The percentage of the pallet face covered by boards. A seven-board 48x40 top deck is roughly 87% coverage.

Questions
Answers to what buyers actually ask
Straight answers, including the ones that cost us the sale.
Why would I choose 42x42 over 48x40?
Three reasons: round or square product that wastes corner space on a rectangle, automated handling where orientation is a liability, or an existing rack and conveyor system already built around it. For general dry freight, 48x40 is cheaper and more available.
Do 42x42 pallets fit standard racking?
Yes, but check beam depth. Racking configured for a 40-inch pallet depth will leave a 42-inch pallet overhanging the rear beam by two inches, which is acceptable for light loads and a bad idea for heavy ones. Confirm your beam spacing before switching.
Is 42x42 the Australian standard?
No, though the two are often confused. Australia's standard is 1165 x 1165 mm, about 45.9 inches square. The 42x42 is a North American size. If you are shipping to Australia, ask before assuming the footprint transfers.
Are 42x42 pallets easy to source second-hand?
Less readily than 48x40, and in regular batches rather than continuously. If 42x42 is a running size for you, tell us the annual volume and we will buy cores against it. Spot demand for this footprint is where lead times stretch from days into weeks.
What loads suit a 42x42 pallet best?
Drums, pails and anything that arrives in a square arrangement. Telecommunications, paint and adhesive shippers use it because four drums sit inside the footprint with no overhang — and overhang is what quietly removes a third of a pallet's effective capacity.
