Standard Pallet Sizes & Dimensions: The Complete Guide

The standard pallet size in North America is 48″ × 40″ — the GMA pallet. It accounts for roughly 30% of all wooden pallets in U.S. circulation and is the workhorse of every truckload, every warehouse rack, and every retail backroom. But “standard” varies by region and industry: ISO recognizes six pallet sizes worldwide, Europe runs on the 800 × 1200 mm EUR pallet, and dozens of specialty sizes serve dairy, automotive, beverage, and chemical supply chains.

This guide gives you every dimension, weight, and use case in one place — plus the trade-offs that decide which size you actually need.

Common pallet sizes — the full chart

These are the U.S. pallet sizes you’ll encounter day to day, with how many fit in a standard 53-foot dry van trailer at single-stack height.

What is a “standard” pallet?

In the United States, “standard” almost always means the 48″ × 40″ GMA pallet (sometimes called a “stringer pallet” or “grocery pallet”). The Grocery Manufacturers Association — now the Consumer Brands Association — standardized it in the 1960s to align grocery distribution. Today every major retailer, broker, and 3PL is built around its footprint.

Internationally, “standard” depends on where you ship. ISO 6780 recognizes six approved sizes; Europe uses the EUR pallet (1200 × 800 mm) under the EPAL pool; Asia uses 1100 × 1100 mm. If you ship globally, no single size is “the” standard — your destination decides.

Standard U.S. pallet sizes by industry

Different industries have settled on different defaults — usually because the pallet matches the case dimensions of whatever they’re shipping.

• Grocery / general freight — 48 × 40 (GMA): The default. Anything that doesn’t need a specialty size ships on this.
• Beverage — 48 × 36 or 36 × 36: Narrower footprint matches case dimensions for soft drinks, beer, and bottled water.
• Dairy — 40 × 40: Square pallet sized to milk crates.
• Drums / chemical — 48 × 48 or 44 × 44: A 48 × 48 holds exactly four 55-gallon drums; 44 × 44 is heavy-duty for pharma.
• Pharmaceutical — 44 × 44 (block): Sterile-compatible, four-way entry, racking-friendly.
• Automotive — 48 × 45: Sized for parts bins on assembly lines.
• Telecom / paint — 42 × 42: Square, easy to rotate, fits cable spools and 5-gallon paint pail layers.
• Military / DoD — 40 × 48: Effectively a GMA, rotated. Spec’d in MIL-STD-1660.
• Aerospace — 88 × 108: The unit load device (ULD) footprint used in cargo aircraft.

ISO and international pallet sizes

ISO 6780:2003 defines six approved pallet dimensions for international shipments. If your freight crosses an ocean, your pallet should match one of these — and it must be heat-treated to ISPM-15.

Standard pallet height

A pallet by itself is shorter than most people think. The empty deck height is typically 4.5″ to 6.5″. With a load, total stacked height is what matters for warehouse racking and trailer clearance:

• Empty pallet height: 4.5–6.5″ (most 48 × 40 GMA pallets are 6.5″)
• Single-stack loaded height: 48″–60″ — the most common ceiling
• Double-stacked in a 53′ trailer: up to 100″ (interior trailer height is 108–110″)
• Warehouse rack pick height: 48″, 72″, or 84″ depending on rack configuration

How much does a pallet weigh?

Weight matters for two reasons: trailers have a 45,000-lb cargo limit, and warehouse racking is rated by load.

Empty pallet weight

Loaded pallet weight

A typical loaded 48 × 40 pallet weighs 1,500–4,500 lbs in the field. Beverage pallets push the upper end; case goods sit closer to 2,000 lbs.

How pallet dimensions are written

Pallet sizes are written stringer length first, deckboard length second — so a “48 × 40” pallet has 48-inch stringers (the boards that run along the bottom, perpendicular to forklift entry) and 40-inch top deckboards. In most warehouse and freight contexts:

• First number: the side a forklift enters from
• Second number: the side that faces the trailer doors when straight-loaded

Stringer vs. block pallets

The two main construction styles are stringer pallets and block pallets. The U.S. defaults to stringers; the rest of the world defaults to blocks.

Stringer pallets have three to four parallel stringers running between the top and bottom decks. They allow forklift entry from two sides (the stringer ends), or four sides if the stringers are notched. Most U.S. 48 × 40 GMA pallets are stringer pallets.

Block pallets have nine solid wood blocks at the corners and middle of the pallet, allowing forklift entry from all four sides. They’re stronger and racking-friendly but cost more. The EUR pallet is a block pallet.

GMA pallet specifications

The GMA pallet has tight published tolerances — and most reputable U.S. pallet recyclers will hit them on a Grade A pallet:

• Footprint: 48″ L × 40″ W
• Deck height: 6.5″ total
• Boards: 7 top deckboards, 5 bottom deckboards, 3 stringers
• Stringer dimensions: 48″ × 4″ × 1.375″, with two notches for 4-way entry
• Wood: hardwood (oak, maple) or southern yellow pine
• Empty weight: 30–48 lbs
• Max load: ~4,600 lbs dynamic, ~7,500 lbs static
• Heat-treated stamp: required for international shipping under ISPM-15

The dimensions aren’t arbitrary — two 40″ pallets side by side measure 80″, comfortably under a 53-foot dry van’s 98–101″ interior width.

How many pallets fit in a 53-foot trailer?

Using standard 48 × 40 pallets, the orientation and stack pattern decide everything:

Pallet quality grades

Size is only half the story. Pallets also come in grades, and the grade decides price as much as condition:

• Grade A (#1): like new — straight, no broken boards, repairs only with new components. The premium tier.
• Grade B (#2): 1–2 repaired boards, may have minor stains or weathering. The most common reused tier.
• Grade C (#3): more visible repair, structurally sound but not for export-grade or aesthetic-sensitive shipments.

Grade A 48 × 40 pallets typically run $10–$16; Grade B sit $4–$8; Grade C $2–$4. For current pricing across regions, see our recycled wooden pallet pricing trends report.

Heat-treated pallets and ISPM-15

Inside the U.S., heat treatment is optional, but food and pharma buyers increasingly require it.

How to choose the right pallet size

Three questions decide it:

1. What’s your product’s footprint? Match the pallet to the case dimensions — a beverage case is 12 × 16 inches, so a 48 × 36 pallet fits 9 cases per layer perfectly. Picking the wrong size means wasted cube and unstable stacks.
2. Where does it ship? International? You’re locked into ISO sizes, with the EUR pallet (800 × 1200 mm) the safest European bet. Domestic only? GMA 48 × 40 is the default.
3. What does your customer accept? Big-box retailers, food distributors, and automotive OEMs each spec their own pallet sizes. Ask the receiving dock before you ship — a rejected pallet is more expensive than the right one.

If you’re stuck choosing between pallet types (stringer vs. block, hardwood vs. softwood, new vs. recycled), read our guide on how to choose the right pallet type for your shipping needs.

Bottom line

The “standard” pallet is the 48 × 40 GMA — and 90% of U.S. shippers will never need anything else. But if you ship overseas, run a specialty industry, or need to squeeze every cubic foot out of a trailer, the right size depends on your case dimensions, your destination, and your buyer’s spec.
