LTL vs. FTL Shipping: What Is the Difference?

What is LTL shipping and when do you use it?

LTL shipping combines freight from multiple shippers in one trailer, so it is usually the best fit for smaller shipments that do not need the speed or dedicated space of a full truck. Your freight shares space with other companies' cargo. Each shipper is billed based on their specific shipment: weight, dimensions, and NMFC freight class.

LTL makes sense when:

• Your shipment is under 10,000 pounds or occupies fewer than 10-12 pallets
• Delivery time is flexible (LTL transit typically runs 1-5 days longer than FTL for the same lane)
• You ship small batches regularly rather than full loads occasionally

LTL carriers operate hub-and-spoke networks. Your freight may change trailers at one or more terminals between origin and destination, which adds handling and transit time but keeps costs low for smaller loads.

What is FTL shipping and when do you use it?

FTL shipping gives one shipper the entire trailer, so it is usually the right choice for heavy, fragile, or time-sensitive freight that benefits from direct transit. FTL reserves the entire trailer for a single shipper. The freight goes straight from origin to destination without stopping at intermediate terminals. You pay for the lane regardless of how much space your freight actually fills.

FTL makes sense when:

• Your shipment weighs 20,000 pounds or more, or fills most of a standard 53-foot trailer
• The freight is time-sensitive or fragile and cannot tolerate additional handling at LTL terminals
• You need guaranteed departure and delivery windows
• Your freight class is high and the LTL rate becomes uncompetitive with a flat truckload rate

How is LTL freight priced differently from FTL?

LTL pricing depends on freight class, shipment weight, and accessorials, while FTL pricing is usually a flat lane rate for the whole truck. LTL carriers price by hundredweight (CWT, or per 100 pounds). The base CWT rate varies by:

• Freight class (50 through 500, assigned by the NMFC)
• Origin and destination ZIP codes (the lane)
• Total shipment weight (heavier LTL shipments earn discount brackets)
• Accessorial charges (liftgate, residential delivery, inside delivery, etc.)

FTL carriers price by the lane -- a flat rate from point A to point B that reflects distance, fuel, market supply and demand for drivers, and seasonality. Freight class does not enter the calculation. If you need a refresher on how class is assigned, read what freight class means.

At what shipment size does FTL become cheaper than LTL?

FTL often becomes cost-competitive once a shipment reaches about 10,000 pounds or roughly 12 pallets, but the real crossover depends on freight class, lane, and carrier pricing. The crossover point varies by:

• Freight class: High-class freight (125 and above) hits the FTL crossover at lower weights, because LTL CWT rates rise steeply for high classes.
• Lane: Dense, high-demand lanes have competitive FTL rates. Thin lanes push FTL prices up and keep LTL competitive longer.
• Carrier pricing: Some carriers offer volume LTL discounts that delay the FTL crossover. Running both quotes is the only reliable way to find your specific breakeven.

A rough rule: if you are shipping more than 8-10 pallets or your LTL quote is coming in above $2,000-2,500 for a domestic lane, request a FTL rate and compare.

What is a freight class and why does it only apply to LTL?

Freight class is the NMFC rating used to price LTL shipments, and it does not apply to FTL because full-truckload carriers charge for the lane instead of shared trailer space. Freight class is an NMFC number (50 through 500) that carriers use to standardize LTL pricing across commodities.

FTL does not use freight class because there is no shared-trailer pricing problem to solve. The shipper rents the whole vehicle. This is why the freight class calculator is an LTL tool. If you are not yet sure whether your shipment will move LTL or FTL, start by calculating freight class and freight density. Those numbers tell you your LTL pricing tier and help you judge whether FTL might be cheaper at your weight.

What are the transit time differences between LTL and FTL?

FTL transit is usually faster because the freight stays on one truck from pickup to delivery, while LTL transit adds terminal stops and rehandling between shared-load moves.

LTL transit time depends on how many terminals the freight passes through. A regional move (under 500 miles) might deliver next day. A cross-country LTL shipment can take 5-7 business days or longer if the freight changes carriers mid-route on an interline segment.

FTL transit time is direct: pickup to delivery with one driver (or team for long-haul). Federal Hours of Service rules limit driving to 11 hours per day, which translates to roughly 500-600 miles per day for solo drivers. A 2,000-mile cross-country move takes about 3-4 days under normal conditions.

How do you choose between LTL and FTL for your business?

Choose LTL for smaller flexible shipments, choose FTL for larger or time-critical freight, and compare both quotes when your shipment sits in the middle range. Run both quotes whenever your shipment is in the gray zone (8,000-15,000 pounds or 8-14 pallets). Outside that range, the choice is clearer:

• Under 5,000 pounds or fewer than 6 pallets: LTL almost always wins on cost.
• Over 20,000 pounds or 20+ pallets: FTL almost always wins on cost and simplicity.
• High freight class (125+) with significant weight: Get an FTL quote earlier than you think you need to.
• Fragile, high-value, or time-critical freight: Lean toward FTL regardless of size.

For LTL shipments, knowing your freight class before you quote saves time and avoids reclassification surprises. Use the OnSumo freight class calculator to determine your class before contacting carriers or brokers. The companion guides on freight density and freight class help if you need to validate the numbers yourself.
