Linear feet of freight describe length occupied along a vehicle floor under a stated loading layout. They are not the same as cubic feet, and they should not be estimated simply by adding every pallet’s longest dimension when units can sit alongside each other.
The calculation below is a rectangular planning exercise. It does not approve a loading arrangement, establish legal payload or replace the carrier’s actual space assessment.
Start with the usable width and orientation
Record how much usable floor width is assumed, which side of each unit sits across that width and which side runs along the vehicle. Then determine how many units fit across and how many rows the quantity needs.
Units across = whole number of units that fit within the assumed width. Rows = quantity divided by units across, rounded up. Occupied length = rows × each unit’s length along the vehicle.

This calculator assumes identical units, one layer, no gaps and one orientation. A result of zero units across means the input does not fit that orientation; it is not a zero-space shipment.
Worked example
Assume six hypothetical units, each 48 inches along the vehicle and 40 inches across, with 100 inches of usable floor width. Two fit across. Six units require three rows. The occupied floor length is 3 × 48 = 144 inches, or 12 linear feet.
Now consider five units under the same assumptions. They still require three rows. One partially occupied row does not automatically reduce the required length to ten feet. Whether its remaining space can be used depends on the real load arrangement.
Why the quoted floor space can differ
Handling clearance, securement, incompatible cargo, projections and packaging constraints can affect the actual layout. Non-stackable freight can reserve useful space even when its height is low. Long freight may restrict the use of areas that a simple rectangle calculation treats as empty.
Tell dispatch whether the unit can be turned and provide photographs of unusual shapes. Do not rotate a hypothetical load in a calculator and assume the goods or packaging permit that orientation.
Keep height and weight beside the result
Linear feet alone do not determine vehicle suitability. Include the maximum packed height and individual gross weights. A load may fit the floor but not the door opening; its total or distribution of weight may also require a different plan.
Our pallet layout example explores a larger rectangular arrangement, while the freight volume calculator answers the separate cubic-space question.
Use it to explain, not to self-assign a rate
A space estimate helps the quoting team understand the load. It is not a universal price formula or an entitlement to a particular linear-foot rate.
