How Many Edge Protectors per Pallet? A Simple Way to Count

Published 26 October 2026 · By Ranjeet Kumar, Proprietor, Solution Enterprises

Short answer: start with four — one full-height board on each vertical corner of the load. Then add protection wherever a strap crosses a top edge: either two short pieces per strap, or one long board along each top edge the straps cross. A pallet with two straps running one way needs four vertical boards plus four short pieces (or two long top boards).

Rule one: four vertical boards

A rectangular load has four vertical corners, and each one gets a board. This is not a matter of taste. The vertical corners carry most of the stacking load when another pallet sits on top, and they are where stretch film and straps press hardest. PAHO’s palletizing guideline for its suppliers says corner boards should run the full height of the load and be used on all corners. Patent literature on pallet wrapping describes the same practice: protectors on the four vertical corner edges.

Three boards is not a saving. The unprotected corner becomes the weak one: film bites into it, the stack leans towards it, and the corner carton is the first to crush. Why vertical boards add stacking strength is covered in pallet stacking strength and edge protectors.

Rule two: protect every top edge a strap crosses

A strap that runs over the top of the load and under the pallet deck bends over two top edges of the load. At each of those points the strap tension is concentrated on a narrow line of carton, and it will cut in. A short angle piece under the strap spreads that line into an area. Distributors sell such pieces specifically for this purpose; Uline describes its laminated paperboard strapping protectors as pads placed on skid corners and held by the strap.

So the short-piece count is simple: number of straps × 2. If you would rather not place loose pieces one by one, lay one full-length board along each top edge that the straps cross. Straps in one direction cross two top edges; straps in both directions cross all four.

Counts for common strapping patterns

Securing	Vertical	Short top pieces	Or long top boards
Film only	4	0	0
2 straps, one way	4	4	2
3 straps, one way	4	6	2
2 + 2 crossed	4	8	4
3 + 3 crossed	4	12	4

With crossed straps, two straps meet over each top corner. A short piece there does double duty, so a careful packer can save a few pieces. A long board along each top edge avoids the question altogether.

When to add more

• Soft or tall faces. On a long pallet face with weak cartons, some packers add a vertical board at mid-face under the film. Treat this as something to test on your own loads, not a fixed rule.
• Top sheets. If the top layer is uneven, a board or sheet across the top spreads strap load better than short pieces at the edges.
• Export and long routes. A container load is handled more often and may sit for weeks. Customers abroad often send their own packing specification, and it usually states where boards go; follow it, even where it asks for more than this guide. For first shipments, see the export packaging checklist.
• Two pallets in one stack. Each pallet load needs its own four vertical boards. A board that spans two pallets does not survive separation at the far end.

Getting the length right

A vertical board should cover the load from the pallet deck to the top layer, so that every carton in the corner column is supported. A board that stops short leaves the top carton bare; one that sticks up above the load lifts the strap off the top edge it is meant to protect. Measure the loaded height and choose a length to match. The edge protector size calculator does this, and also suggests a leg width and thickness.

Turning the count into an order

Multiply boards per pallet by pallets per month, then add a margin for spoilage and the odd pallet that needs re-packing. For example, 400 pallets a month with two straps one way and long top boards uses 400 × (4 + 2) = 2,400 boards a month, in two lengths: one for the verticals and one for the top edges. Keep the two lengths on separate, clearly labelled stock so the line does not mix them. For a reorder rhythm, see the warehouse packaging replenishment guide.

When you have the count and the lengths, send them with your leg size and thickness through the quote form. The shapes we make are on the paper angle board page.

Common questions

Do I need boards if the load is only stretch wrapped?

Usually yes, at least the four verticals. Film squeezes the corners hardest. See edge protectors with stretch wrap.

Should the bottom edges be protected too?

Where the strap runs under the pallet’s top deck, it bends around the pallet rather than the bottom carton, so bottom pieces are rarely needed. Check where your strap actually touches.

Is one U-shaped board better than two short L pieces?

For a single long product such as a panel or a coil edge, a U channel can be neater. For a pallet of cartons, L-shaped pieces are the usual choice.
