Estimate boxes per layer, total pallet count, stack height, and space utilization for FBA, WFS, 3PL, and freight shipments. Planning tool — not a carrier compliance guarantee.
This calculator is a planning estimate, not a carrier compliance guarantee. Actual pallet loading depends on box compressibility, pallet board strength, forklift reach, and carrier or fulfillment center rules. Always verify pallet specifications with your carrier, Amazon Seller Central, WFS guidelines, or 3PL before booking freight. No live carrier API call is made.
A pallet calculator estimates how many boxes fit on a pallet given box dimensions, pallet dimensions, and stacking constraints. It is used for freight planning, 3PL onboarding, Amazon FBA palletized shipment prep, and warehouse layout optimization. This tool compares normal and rotated box orientations to find the denser layout.
Divide the usable pallet length by the box length (round down). Do the same for width. Multiply those two numbers to get boxes per layer:
Boxes per layer = floor(palletLength / boxLength) × floor(palletWidth / boxWidth)
Rotate the boxes and repeat to compare. Divide the maximum stack height by box height to get the number of layers. Multiply layers by boxes per layer for the total.
Total boxes = boxesPerLayer × layers
Freight cost is billed per pallet or per weight, whichever is greater. Low pallet utilization means you are paying for space you are not using. High utilization (85–95%) reduces per-unit freight cost but risks carrier rejections if the stack exceeds height or weight limits.
For Amazon FBA, each pallet incurs a receiving fee. Fewer pallets with higher utilization is generally better. For 3PL, some charge per pallet per month — higher utilization reduces the per-SKU storage cost.
Divide the pallet length by the box length and the pallet width by the box width, rounding down each result. Multiply those two numbers to get boxes per layer. Then multiply by the number of layers that fit within your maximum stack height to get total boxes per pallet. The pallet calculator does this automatically and compares normal vs rotated box orientation to pick the layout that fits more boxes.
The most common pallets in North America are the US pallet (48 × 40 inches) and the Euro pallet (1200 × 800 mm). Asia uses 1100 × 1100 mm. This calculator supports all three plus a custom option for non-standard pallets.
Yes. This calculator helps you plan FBA palletized shipments to Amazon fulfillment centers. Use the output to estimate total boxes, pallet weight, and stack height before booking freight. Amazon has specific pallet requirements — verify current guidelines in Seller Central before shipping.
No. This calculator is a planning tool. It estimates box layout, stack height, and pallet weight based on your inputs. Actual pallet compliance depends on carrier requirements, Amazon FBA pallet specifications, WFS guidelines, and local freight regulations. Always verify with your carrier or fulfillment provider before booking.
Try rotating the boxes (swap length and width) to see if more fit per layer. Choose a pallet size that matches your dominant box dimensions. Reduce overhang — boxes that hang over the pallet edge reduce stability and may violate carrier rules. Adjust box count or pallet dimensions until used area reaches 85–95% before adding a second pallet.
Pallet utilization is the percentage of the pallet's top surface area covered by boxes. A higher utilization percentage means less wasted freight space and better cost efficiency. Most shipments target 80–95% utilization. Below 70%, consider whether a second smaller pallet or different box mix would reduce per-unit freight cost.
