The calculation, without hidden assumptions
Estimate the floor length a shipment occupies instead of multiplying pallet count by one guessed length. MAXScanner checks how many identical rectangular handling units fit across the usable trailer width, optionally compares a 90° floor rotation, then reports rows and occupied linear feet. Carrier capacity rules remain separate because tariff thresholds and rounding are not universal.
How to use this calculator
Measure the greatest wrapped pallet or handling-unit floor footprint, including overhang and projections.
Enter quantity and usable trailer width in the same selected dimension unit.
Allow 90° rotation only when the freight and loading process permit the alternate floor orientation.
Review the chosen orientation, units across, rows, occupied linear feet and trailer-length utilization.
If your carrier contract specifies a linear-foot review threshold, enter it as a comparison only; confirm the actual tariff before tendering.
Where people use it
- •Estimate LTL floor space before requesting a quote.
- •Compare standard pallet orientation with a legal 90° floor rotation.
- •Screen whether a shipment is approaching a carrier-specific capacity review threshold.
- •Estimate nominal trailer length remaining for a single-SKU straight-row load.
- •Pair floor-space planning with freight density and pallet-load calculations before tender.
Six 48 × 40 in pallets in a 96 in usable width
With rotation allowed, the solver compares both floor orientations. Two 48-inch cross-trailer widths fit across 96 inches, leaving the 40-inch dimension along the trailer. Six pallets require three rows, so occupied length is 3 × 40 = 120 inches = 10 linear feet.
What the result does not assume
- •This is a deterministic straight-row floor-placement estimator, not a mixed-SKU or global 2D/3D packing optimizer.
- •Trailer usable width and length vary by equipment. Enter dimensions appropriate to the actual equipment rather than treating a nominal trailer name as guaranteed clearance.
- •Stacking, vertical clearance, axle loading, securement, loading sequence, wheel wells, door aperture and irregular freight are not modeled.
- •There is no universal LTL linear-foot surcharge threshold. The optional threshold is user-entered and is never presented as a carrier rule.
- •Carrier billing may round or measure occupied space differently from this geometric estimate; confirm the tariff or contract that governs the shipment.
Frequently asked questions
How do I calculate linear feet for LTL freight?+
Work out how many handling units fit across the usable trailer width, round the required row count up, multiply rows by the depth of each row, then divide occupied inches by 12.
Why is pallet rotation important?+
A 90° floor rotation swaps which pallet dimension runs across the trailer. That can change both units per row and row depth, so the shorter valid layout is not always obvious from pallet count alone.
Is there one standard LTL linear-foot rule?+
No. Carrier tariffs and customer contracts can use different thresholds, rounding and capacity provisions. MAXScanner therefore applies only a threshold you explicitly enter.
Should pallet overhang be included?+
Yes. Use the greatest actual wrapped floor footprint, including overhang, protective packaging or projections, because that is the space the handling unit consumes.
Does this calculator double-stack pallets?+
No. It estimates single-layer floor positions. Only reduce floor positions for stacking when you have a separate load plan confirming stackability, height and load-bearing limits.
How is linear feet different from freight density?+
Linear feet measures occupied trailer floor length. Freight density divides shipment weight by cubic volume. They answer different planning and tariff questions, so check both for larger LTL shipments.
