What this means
- This shipment occupies 20.0 linear feet (240 inches) of trailer floor space across 6 rows.
- 12 pieces require 12 floor positions at up to 2 units side-by-side.
- Utilizes 37.7% of a 53 ft trailer floor (33.0 linear feet remaining).
- Carrier thresholds and pricing rules vary. Many LTL carriers apply cubic capacity or linear foot rules (often between 10 and 20 linear feet) that invoke spot quotes or linear foot minimums.

Assumptions used
- Linear feet measures trailer floor length occupied along the trailer axis from front to rear.
- 96 in is a reference interior planning width; actual interior widths of North American dry vans range between 96 and 100 inches.
- 53 ft (636 in) is a standard North American trailer reference length assumption; 28 ft pup trailers and 48 ft vans are also widely operated.
- GMA pallet dimensions (48 × 40 in) reflect the Grocery Manufacturers Association standard footprint.
- Items are arranged to minimize total floor length using 2D strip packing.
- Carrier linear-foot surcharges, cubic capacity rules, and minimum charge thresholds vary by carrier tariff.

Planning Notice & Scope Boundary
Carrier linear foot thresholds, cubic capacity rules, and pricing penalties vary by carrier tariff.
Formula & Calculation Methodology
Linear Feet = Total length of trailer floor occupied from front to back, considering items side-by-side across trailer width.
Linear Feet = Trailer Floor Length Occupied (in inches) / 12| Variable | Definition & Basis |
|---|---|
| Linear Feet | Trailer floor length in feet occupied by shipment |
| Usable Width | Internal trailer width (typically 96 to 102 inches) |
Worked Example: 12 Standard GMA Pallets on a 53ft Trailer
Shipping 12 non-stackable 48 × 40 in pallets on a standard 53ft dry van (96 in usable interior width).
Input Parameters
- Pallet Size48 × 40 in
- Quantity12 pallets (non-stackable)
- Trailer Width96 in
Step-by-Step Calculation Breakdown
- 1Pallets loaded turned side-by-side (pinwheeled or straight): 2 pallets of 48 in width fit across 96 in trailer width.
- 2Each row of 2 pallets occupies 40 in of trailer length.
- 312 pallets require 6 rows: 6 × 40 in = 240 inches of trailer length.
- 4Convert to feet: 240 in ÷ 12 = 20.0 linear feet.
Assumptions Used
- Assumes items are loaded on the trailer deck utilizing available width before extending lengthwise.
- Standard dry van trailer width modeled as 96 in interior usable space.
Important Limitations
- Carriers enforce proprietary linear foot rule thresholds (commonly spot-quoted when freight exceeds 12 to 20 linear feet).

Frequently Asked Questions
What is the LTL linear foot rule?
Many North American LTL carriers enforce a linear foot rule (often 12 to 20 feet) where shipments exceeding that length are deemed capacity-consuming and subject to higher truckload spot rates or minimum charge floors.
How many pallets fit in a 53-foot trailer?
A standard 53ft dry van trailer accommodates 26 standard 48 × 40 inch pallets straight loaded or up to 30 pinwheeled on a single tier.
