What is pallet configuration?

Pallet configuration is how cases are arranged on a pallet: how many fit per layer and the stacking pattern they form. Common patterns are column (stacked straight), brick and pinwheel (rotated so seams overlap), and interlocked (alternating layers), each trading capacity against stability.

Which pallet stacking pattern is most stable?

Interlocked and pinwheel patterns are the most stable against toppling because rotating the boxes ties the layers together. Column stacking is strongest vertically (best compression strength) but least stable laterally, so it needs good strapping or stretch-wrap.

What is a column stack vs an interlocked stack?

A column stack places each box directly on the one below, corner to corner, giving maximum compression strength but poor lateral stability. An interlocked stack rotates boxes each layer so seams don't align, tying the stack together for stability at the cost of some compression strength.

How do I lay out boxes on a 48x40 pallet?

Fit case footprints into the 48x40 inch deck, rotating some boxes to fill gaps, and keep everything inside the pallet edge to avoid overhang, which weakens the stack and draws damage claims. Cases that divide evenly into 48x40 tile with the least waste.

Pallet Configuration & Layout Patterns

Pallet configuration is how you arrange cases on the pallet — both how many per layer and the pattern they form. The four common patterns are column (boxes stacked straight, strongest vertically), brick and pinwheel (layers rotated so seams overlap, more stable), and interlocked (alternating layers that tie the stack together). The right one trades a little capacity for stability. Here’s each pattern, when to use it, and how to lay out a 48×40 pallet — with the calculator one click away.

Column stacking

Boxes stack directly on top of each other, corner over corner. This is the strongest vertically — a box’s corners carry most of its compression strength, so column stacks bear the most weight and protect the product best. The downside is lateral instability: with no overlap between layers, the stack can shear or topple in transit unless it’s well strapped or stretch-wrapped.

Column stacks are strongest straight down; interlocked stacks are strongest against a shove. Match the pattern to the risk.

Brick, pinwheel and interlocked

These rotate boxes within or between layers so the vertical seams don’t line up. A pinwheel turns boxes around a center gap; a brick pattern offsets each row like masonry; interlocked alternates the orientation every layer. All three tie the stack together and resist toppling far better than a column — at the cost of losing some compression strength and, sometimes, a box or two of capacity. They shine for lighter, sturdier cartons that won’t crush.

Laying out a 48×40 pallet

Start from the footprint. Cases that divide evenly into 48×40 tile with little waste; odd sizes leave gaps you fill by rotating some boxes. Keep everything inside the pallet edge — overhang of even an inch cuts stack strength sharply and draws carrier damage claims. Underhang (boxes short of the edge) wastes cube. The goal is a full, square footprint with a flat top to stack on. The boxes-per-pallet math gives the counts.

Choosing a pattern

Heavy or crush-sensitive product → column, strapped well. Light, strong cartons that need to survive handling → interlocked or pinwheel. Mixed or fragile → interlock the lower layers for stability and column the top. Whatever the pattern, stretch-wrap to the pallet and consider corner boards for tall loads.
