How many pallets fit in a 20ft and 40ft container? (2026 guide)

The honest answer is: it depends on your loading pattern, not just your container and pallet size. Published figures for “pallets per container” vary across the industry — and both the higher and lower numbers you’ll find are usually correct, just for different loading arrangements.

This guide gives you the real ranges for Euro pallets, GMA (standard American) pallets, and double-stacking scenarios across 20ft, 40ft, and 40ft High Cube containers — along with why the range exists and how to get a precise number for your specific shipment.

Quick answer

Ranges reflect single-layer floor loading. The lower end of each range is a simple grid layout; the higher end reflects optimised block-stow or pinwheel arrangements. Double-stacking (where cargo allows) can roughly double these figures. For the internal dimensions behind these figures, see our guide to shipping container dimensions.

Why the numbers vary — loading pattern matters more than container size

Two operations can use the same container and the same pallets and still fit a different number, because the loading pattern determines how much of the container’s width and length is actually used.

A simple grid layout — pallets placed in straight rows with consistent spacing — is the easiest to plan but wastes space near the container walls and doors. An optimised block-stow or pinwheel arrangement rotates some pallets and tightens spacing to use almost the entire floor area, typically adding 2 to 4 more pallets per container compared to a simple grid.

This is also why two reputable sources can both be correct while quoting different numbers — “10 Euro pallets” and “11 Euro pallets” in a 20ft container are both real, achievable figures depending on how carefully the load is arranged.

Euro pallets vs GMA pallets

The Euro pallet (1200 × 800mm) is the international standard, especially across Europe and in most cross-border ocean freight. The GMA pallet (48 × 40 inches, or 1219 × 1016mm) — sometimes called the standard American pallet — is the North American standard, common in retail, grocery, and food distribution.

Because the Euro pallet has a narrower footprint, more of them typically fit in the same container space compared to GMA pallets, even though the difference in any single dimension looks small on paper.

Double-stacking — when it’s possible and when it isn’t

Double-stacking pallets roughly doubles container capacity, but it is not always safe or appropriate. Cargo needs to be able to bear the weight of a second pallet stacked on top without crushing, shifting, or becoming unstable. As a general guideline, the total loaded pallet height — including the pallet itself — should not exceed approximately 1.7 meters for safe handling and stacking. Fragile goods, irregularly shaped cargo, and anything close to the container’s weight limit are usually not good candidates for double-stacking.

These ranges are useful for early planning, but they are generic — they don’t know your exact pallet dimensions, your cargo height, or whether your goods can be double-stacked.
