Load Planner
Freight regularly costs more than the boxes. This works out how many trailers your quantity needs, and exactly what you burn by shipping assembled.

Size in, trailers out
53-foot dry van, 26 pallet positions, knocked-down counts from our own loading records.
Last trailer is about 8% full. Rounding up to a full load is usually cheaper per box than paying for a partial one.
- Boxes per 53′ trailer
- 480
- Total cubic capacity
- 40,000 cu ft
- Freight penalty if assembled
- 18× more trailers
Assembled counts assume single-stacked pallet positions. Some geometries nest and do better than 26 — tell us the box and we will check against the actual loading pattern.
How many gaylord boxes fit in a 53-foot trailer?
About 480 knocked-down 48×40×36 boxes, or 26 pallets of assembled ones. Half gaylords reach roughly 900 knocked down.
Why is assembled so much worse?
Because you are paying to ship air. A flat-packed box occupies roughly a quarter of the space of an assembled one, and floor positions cap you at 26 regardless.
Should I round up to a full trailer?
Usually yes. Half a trailer costs nearly the same as a full one, so the marginal boxes are close to free — provided you have somewhere to put them.
Does this include weight limits?
It does not need to. Bulk corrugated never approaches a 44,000 lb payload ceiling; it is a cube calculation from start to finish.
