About 9 to 10 standard 48 by 40 inch pallets fit on a 20 ft floor in a single layer packed edge to edge. Leave a working aisle and plan on 8. Stack low, stable freight two high and the total climbs toward 18. The bigger variable is not the container size, it is how you plan to load it.
Before you count pallets, decide whether you are loading them once and leaving them, or loading and unloading regularly. Packed edge to edge, a single layer of about 9 to 10 standard pallets covers the roughly 160 square feet of floor a 20 ft gives you. Keep a working aisle open so you can reach individual pallets later and that drops to about 8.
Stack tight, stable freight two pallets high and the same floor holds closer to 18, sometimes 20 if the load is light and even. That extra capacity only works if nothing needs pulling out until the whole load comes back off, because a stacked pallet in the back of a 20 ft is not something you retrieve on a Tuesday afternoon.
A standard GMA pallet measures 48 by 40 inches, and a 20 ft interior runs roughly 19 feet 4 inches long by about 7 feet 8 inches wide. Orient pallets with the 40 inch side across the width and two fit side by side with inches to spare, four rows deep before you run out of length. That is 8, and the roughly 40 inches left at the door end is where the ninth goes, turned crossways, with a tenth when the pallets run a little under standard size. Used boxes vary, so measure the actual unit before you plan a load down to the inch.
Euro pallets, oversized crates, or irregular loads change that math fast. A pallet even a few inches wider than standard can knock the two across pattern down to one, cutting your usable count nearly in half. Measure what you are actually shipping, not the industry standard, before you book a size.
The 9 to 10 figure assumes a clean load with no wasted space, and real yards rarely work that way. A forklift needs a turning radius near the door, uneven pallets need shimming, and freight that is not perfectly square wastes a few extra inches every row.
If your pallet count is pushing past what a 20 ft holds comfortably in a single layer, a 40 ft roughly doubles the floor without doubling the price. See how a 40 ft's pallet count actually works out, since the extra length does not split evenly.
For most farms, small shops and one-time moves, though, a 20 ft covers the load with room to spare, and it is the size that fits a normal driveway without needing extra pull-in space.
Pallet counts here are a planning estimate, not a promise, because the site does not publish one fixed figure and your load is not standard freight off a shelf. Tell us your pallet size, how many, and whether you are stacking, and we will help you pick between a 20 ft and a 40 ft before you commit to either.
We will help you land on a 20 ft or a 40 ft before you book either one.
