Trailer load
planner.

Per-layer counts computed from interior dimensions in both orientations, layers from your actual load height, and a weight check against the federal gross limit. No lookup tables, no rounding in our favour.

LoadedTwo strapped columns in a dry van. The planner below works out how many of these you actually get per load.

Footprint: 48" × 40" GMA
Equipment: 53 ft dry van
Pallets per load: 48
Limited by: weight

What this cannot know

Your actual trailer's interior — builds vary by an inch or two
Whether your dock can accept double-stacked freight
Axle distribution, which can fail even at legal gross
Whether your load is crushable under a second layer
Local bridge-formula limits on the route

Every number we publish, in one place

The same appendix appears at the foot of our reference pages so you never have to leave an article to check a figure. All of it is revised annually and matches the constants used by the Carbon Ledger.

53 ft dry van	100–102"	48×40 straight	26 pallets
53 ft dry van	100–102"	48×40 pinwheel	28 pallets
48 ft dry van	98–100"	48×40 straight	24 pallets
20 ft container	92.5"	1200×800 EUR	11 pallets
40 ft container	92.5"	1200×800 EUR	24 pallets
40 ft HC container	92.5"	1200×1000 ISO	20 pallets

Service rings from Meeks Blvd

Beyond roughly 950 miles, freight emissions cancel the carbon benefit of reuse. We will say so and recommend a nearer yard.
Ring	Distance	Example markets	Delivery window	Pickup window
One	0–60 mi	St. Louis, St. Charles, Metro East	Next business day	48 business hours
Two	60–180 mi	Columbia, Springfield IL, Cape Girardeau	2–4 business days	Within the week
Three	180–300 mi	Kansas City, Memphis, Indianapolis	Weekly scheduled run	By arrangement
Beyond	300+ mi	Quoted case by case	By arrangement	Full trailers only

Handling and rack dimensions

Measure your own equipment before specifying a pallet. These are the values that decide whether a footprint works in your building.
Dimension	Typical value	Note
Fork length	42"–48"	Must not protrude beyond the far side of a 48" pallet
Fork width	4"–6"	Wider forks spread load across deck boards
Fork thickness	1½"–2"	Determines minimum pallet entry height
Fork spread, GMA entry	24"–27" centres	Between the stringers of a three-stringer pallet
Pallet-jack wheel path	6½" clear	Why notched stringers do not admit jacks
Minimum entry height	3½"	A crushed bottom deck blocks the forks entirely
Rack beam span, two pallets	≥ 96" clear	For two 48×40 pallets, 40" face out
Flue space, back to back	≥ 6"	Most fire codes; check your jurisdiction

Glossary — thirty terms worth knowing

Core: A used pallet bought for grading — the currency of the industry.
Deck board: Any board on the top or bottom face of a pallet.
Lead board: The outermost deck board at each end; absorbs every fork entry.
Stringer: The long member running the length of a stringer pallet; usually three.
Stringer board: On a block pallet, the board that ties the blocks together.
Block: One of the nine supports in a block pallet.
Notch: The cut-out in a stringer that creates four-way fork access.
Chamfer: A bevel on a lead board's lower edge to ease fork entry.
Companion: A full-length board nailed alongside a damaged stringer. A strong repair.
Plug / scab: A short piece fixed over a break. A weaker repair; #2 grade here.
Re-nail: Restoring the fastener pattern on a loose but intact pallet.
Regrade: Moving a pallet between grade lanes after inspection.
Down-cut: Re-cutting a larger deck into a smaller footprint.
Static load: Capacity at rest on a flat, continuous surface.
Dynamic load: Capacity while being lifted and moved.
Racked load: Capacity spanning beams with no deck support. Always the smallest figure.
Unit load: Pallet, product and wrap considered as one structure.
Overhang: Load or deck projecting beyond its support. The leading cause of rack failure.
Flue space: The gap between back-to-back rack bays; six inches minimum in most codes.
GMA: The Grocery Manufacturers Association 48×40 specification.
EPAL: The licensing body for the European 1200×800 block pallet.
ISPM-15: The international phytosanitary standard for wood packaging.
HT: Heat treatment: 56 °C at core for 30 minutes.
IPPC mark: The wheat-sheaf stamp evidencing phytosanitary treatment.
Collar: Four hinged timber sides that turn a pallet into a container.
Top cap: A lightweight cover protecting the uppermost layer of a stack.
Dunnage: Timber used to fill voids, brace loads and spread point loads.
Fiber: Ground wood: mulch, animal bedding or boiler-grade chip.
Diversion rate: Share of intake kept out of landfill. Ours is 100%.
Reuse rate: Share of intake that leaves as a pallet. Ours is 94%.
