LTL Pallet Height and Weight Limits: How to Build Wholesale Pallets Carriers and DCs Accept

A wholesale order can be picked perfectly and still go wrong at the dock. The pallet is too tall for the receiving DC, too heavy for the carrier's handling assumptions, or built with cartons hanging over the edge. The result is a refused delivery, a reclass on the freight bill, or a chargeback weeks later. Most of those problems are decided when the pallet is built, not when the truck arrives.

This guide covers the height, weight and footprint limits that shape an LTL pallet, where those limits come from, and what to put in writing before your warehouse starts building pallets for a new account.

Where pallet limits actually come from

There is no single "maximum pallet height for LTL." Three different parties set limits, and the strictest one wins:

A 53-foot dry van has far more interior height than any pallet you would build, so the trailer is rarely the binding constraint. The carrier's tariff and the customer's routing guide usually are.

Height: the number that gets shipments refused

Retailer and distributor DCs set pallet height caps so loads fit their rack openings and can be handled safely. Many routing guides set a total height somewhere in the range of 50 to 72 inches, measured including the pallet itself, and some specify different caps for different product categories or for floor-loaded versus palletized freight.

Practical rules that keep height from becoming a problem:

• Measure from the floor, not from the deck boards. A standard wooden pallet adds roughly five to six inches.
• Write the cap into the SKU setup, not just the account notes. If the case pack is 12 inches tall and the cap is 60 inches, that pallet holds four layers, not five.
• Check the guide for each customer separately. Two retailers can carry the same item and require different pallet heights.

Stackable or not: the decision that changes your bill

LTL carriers price on the assumption that freight can share space. A pallet that cannot have anything placed on top of it uses the full height of the trailer above its footprint, so many carriers apply charges for non-stackable freight or rate it on the space it actually occupies.

What usually makes a pallet non-stackable:

• A pointed or uneven top layer
• Fragile goods without a load-bearing top sheet or cap
• Heights tall enough that a second pallet will not fit above it

If the product can take weight, build it flat-topped with a top sheet and say so on the bill of lading. If it cannot, declare it, because a carrier who discovers it later can rebill the shipment.

Weight and density

Weight limits show up in two places. The receiving dock may cap per-pallet weight for their equipment and racking. The carrier uses weight and dimensions together to work out density, and density increasingly drives freight class. A light pallet built tall has low density and often classes higher, which costs more.

We covered how class and accessorials set the price in what actually sets the LTL bill on wholesale orders. For pallet building, the takeaway is simple: record actual dimensions and weight for every pallet rather than estimating from the case count. Carriers reweigh and remeasure, and a mismatch between the BOL and the scale is the most common cause of a corrected invoice.

Footprint and overhang

The standard U.S. pallet is 48 by 40 inches, and most routing guides expect it. Two footprint mistakes cause most of the trouble:

• Overhang. Cartons sticking out past the pallet edge get crushed by forklifts and neighboring freight. Many guides prohibit overhang entirely. The fix is a pallet pattern that keeps cartons inside the edges, even if that means a slightly shorter layer.
• Underhang beyond tolerance. A load pulled far in from the edges can shift and is less stable. A small inset is normal; a large gap is a sign the case dimensions and the pallet pattern do not match.

A pallet build checklist to agree before the first order

Before your warehouse ships the first purchase order for a new wholesale account, settle these items in writing:

1. Maximum height including the pallet, per customer
2. Maximum weight per pallet, per customer
3. Pallet type and condition, including whether a specific grade or pallet exchange is required
4. Stackable or not for each SKU
5. Layer pattern for each case pack, including how many cases per layer and how many layers
6. Wrap and protection: stretch film, corner boards, top sheets
7. Labeling: where the pallet and carton labels go
8. Mixed pallets: whether SKUs may share a pallet and how they must be separated

Most of these questions also come up in the broader picture of how B2B orders move through the warehouse as case picks and pallet builds. The difference is that pallet limits are the ones that can stop a shipment outright at the receiving dock.

Where a 3PL fits

A fulfillment partner that handles wholesale orders should be able to store each customer's pallet rules against the account, build to them, and photograph and measure finished pallets before they leave. That record matters when a receiver disputes the condition of a delivery or a carrier rebills the shipment.

IDCEA handles case-pick and pallet orders for brands selling into wholesale and retail accounts from Southern California. You can see how that service is set up on our B2B fulfillment services page, or contact us with your routing guides and case-pack data to scope a quote.
