The Basics: What FTL and LTL Mean
FTL means your freight gets an entire trailer — typically a 53-foot dry van, flatbed, or reefer. The truck picks up at your dock, drives to the destination, and delivers. No other freight shares the space. LTL means your freight shares trailer space with shipments from other companies. An LTL carrier picks up from multiple shippers, consolidates freight at a terminal, and delivers to multiple receivers. Your shipment may be handled (loaded and unloaded) two to four times between origin and destination.
When to Use FTL
FTL makes sense when your shipment weighs more than 10,000 lbs or fills more than 10 linear feet of trailer space. It also makes sense for fragile or high-value goods that cannot tolerate multiple handling events, time-sensitive shipments where transit time matters, and freight that requires dedicated temperature control. A typical FTL shipment from Toronto to Chicago costs $1,800 to $2,500 (dry van) and takes 1 day of transit. The rate is per truck, not per pound — so whether you ship 20,000 lbs or 40,000 lbs, the cost is similar.
When to Use LTL
LTL makes sense when your shipment weighs between 150 lbs and 10,000 lbs and you do not need the entire trailer. LTL pricing is based on weight, freight class (a density-based classification system from NMFC), and distance. A 2,000-lb shipment from Toronto to Chicago might cost $400 to $700 via LTL — significantly less than booking a full truck. The trade-off is transit time (3 to 5 days vs 1 day for FTL) and handling. LTL freight is loaded and unloaded at terminals, which means more touchpoints and higher damage risk for fragile goods.
The Cost Crossover Point
There is a weight range — roughly 8,000 to 12,000 lbs — where LTL and FTL costs converge. Below 8,000 lbs, LTL is almost always cheaper. Above 12,000 lbs, FTL is almost always cheaper. In the crossover zone, you should get quotes for both modes. Volume LTL (also called partial truckload) is another option in this range. A volume LTL shipment gets dedicated space on the trailer without terminal handling — fewer touchpoints than standard LTL, but lower cost than a full truck. This is the sweet spot for shipments in the 6,000 to 12,000 lb range.
Freight Class and Why It Matters
LTL pricing depends heavily on freight class, which ranges from Class 50 (dense, easy to handle — like bricks) to Class 500 (light, bulky, fragile — like ping pong balls). Your freight class is determined by density (weight per cubic foot), stowability, handling difficulty, and liability. Getting your freight class wrong is one of the most common and expensive LTL mistakes. If you declare Class 70 but the carrier re-weighs and reclassifies to Class 125, you will receive an invoice adjustment that can double or triple your shipping cost. Always measure and weigh accurately, and ask your logistics partner to verify your classification before booking.
Damage Risk: The Hidden Cost
FTL freight is loaded once and unloaded once. LTL freight may be handled three to five times — pickup, origin terminal, linehaul transfer, destination terminal, delivery. Each handling event is a damage opportunity. If you ship products that are fragile, irregularly shaped, or high-value, the lower freight cost of LTL may be offset by higher damage rates and claims. Proper packaging and palletizing reduce this risk, but they do not eliminate it. For goods where a damage claim would cost more than the FTL-LTL price difference, FTL is the safer choice.
Making the Right Choice
Ask three questions: (1) Does my shipment exceed 10,000 lbs or 10 linear feet? If yes, FTL. (2) Is my freight fragile, high-value, or time-sensitive? If yes, lean toward FTL even for smaller shipments. (3) Am I in the 6,000 to 12,000 lb range? If yes, get quotes for both FTL and volume LTL. A good logistics partner will quote both options and recommend the best fit based on your specific shipment — not push the mode that generates the highest margin.
