Trailer Loading Calculator — How to Use

This tool calculates how many pallets will fit into a 52.6 ft box trailer (631.2" L × 98" W × 105" H interior). It handles up to 5 different pallet sizes in a single load and will work backwards from a known customer quantity to show you how much room is left for other pallets.

Step 1 — Confirm the trailer dimensions

At the top of the page, the trailer is preset to 631.2" long, 98" wide, 105" tall. Change these only if you are loading a different trailer.

Step 2 — Enter your pallet(s)

Fill in a row for each pallet type, up to 5. For each pallet, provide the following:

• Include? — check the box to include this pallet in the calculation.

• Recycled Boards — Yes or No. If Yes, the calculator automatically sets the pallet height to 4.75".

• Length (L) — in inches.

• Width (W) — in inches.

• Height (H) — in inches. (Skipped automatically if Recycled = Yes.)

• Type — 4-way or 2-way. A 2-way pallet can only be loaded with its length running down the trailer. A 4-way pallet can be rotated, which often fits more.

• Required Qty (optional) — enter this only if the customer has ordered a specific number. Leave blank for pallets you want the tool to fill with whatever space is left.

Step 3 — Click Calculate Load

The results appear below the form.

What the results show

For each pallet, you will see:

• Orientation — which way the pallet is loaded (for example "40×48, W along trailer length — rotated"). The first number is the dimension running the length of the trailer.

• Stack High — how many pallets tall.

• Across Trailer — how many fit side-by-side.

• Rows Used / Length Used — how many rows deep and how many inches of trailer length this pallet consumes.

• Total Count — the final number of pallets loaded for that type.

At the top, a summary line shows total pallets loaded and how much trailer length is used vs. unused.

How it decides the best orientation

For 2-way pallets, only one orientation is possible. For 4-way pallets, the tool compares three options and picks the one that fits the most:

1. LxW — length along the trailer length.

2. WxL (rotated) — width along the trailer length.

3. Pinwheel — alternating rows of LxW and WxL (only used when a pallet is loaded by itself).

Mixed loads and customer orders

If any pallet has a Required Qty entered, the tool first reserves the exact number of rows needed for that order, then distributes the remaining trailer length among the pallets that do not have a required quantity. This tells you, for example, "the 200 48×40 pallets the customer ordered take 240 inches of the trailer — here is what else you can fit in the remaining 391.2 inches."

Tips

• If a pallet will not fit, the calculator warns you.

• If the combined required quantities exceed trailer capacity, the calculator warns you and shows how much length you would need.

• The Reset button clears all inputs.
