With over 25,000 daily users, it's the most trusted tool for freight classification in America.

📊 Freight Density Formulas

Volume (ft³): (L×W×H) ÷ 1728
Density (lb/ft³): Weight ÷ Volume
DIM Weight: (L×W×H × Units) ÷ 139
Billable Weight: Max(Actual, DIM)
LTL DIM Factor 2026: 139
Parcel DIM Factor: 166

📈 2026 Freight Class by Density

≥50 lb/ft³: Class 50 (Dense - Steel)
35-49.9: Class 55 (Auto parts)
22-34.9: Class 60 (Furniture)
15-21.9: Class 70 (Boxed goods)
8-14.9: Class 92.5 (Clothing)
5-7.9: Class 125 (Plastics)
3-4.9: Class 175 (Ping pong tables)
1-2.9: Class 250 (Pillows)
<1: Class 400 (Foam)

📐 Example: 1 Pallet - XPO Density Calculation (May 2026)

Dimensions: 48"L × 40"W × 36"H, Weight: 500 lbs

Volume: (48×40×36) ÷ 1728 = 69,120 ÷ 1728 = 40 ft³

Density: 500 lbs ÷ 40 ft³ = 12.5 lb/ft³

Freight Class: 12.5 lb/ft³ → Class 92.5 (Light category)

DIM Weight (LTL): 69,120 ÷ 139 = 497 lbs

Billable Weight: max(500, 497) = 500 lbs

Potential Savings: Wrong class (Class 70) would cost 15-20% more!

❓ Frequently Asked Questions About Freight Density (May 2026)

What is my freight density?

Your freight density is calculated by dividing total weight (lbs) by total volume (cubic feet). Use our XPO density calculator above: enter length, width, height, and weight. Density = (Weight × Units) ÷ ((L×W×H) ÷ 1728). This determines your freight class and shipping cost.

How do I calculate freight density for multiple boxes?

For multiple boxes: 1) Add all weights together, 2) Stack boxes to calculate total cube (L×W×H of entire stack), 3) Enter as single unit in our calculator. For example, 10 boxes each 12x12x12 weighing 20lbs → total weight 200lbs, stack as 12x12x120 = 10 ft³, density = 20 lb/ft³.

What density requires Class 50 freight?

Density of 50 lb/ft³ or higher qualifies for Class 50 - the lowest freight class and cheapest rates. Examples include steel, machinery, bricks, and dense manufacturing materials.

Does XPO use the same density calculations?

Yes! XPO Logistics follows the same NMFC density standards as all major LTL carriers. Our calculator matches the formulas XPO uses for their density-based pricing.

What freight class is 12 lb/ft³ density?

12 lb/ft³ falls in the 8-15 lb/ft³ range, which is Class 92.5 (Medium-Light).

How much can I save with correct density?

Correct density classification can save 15-25% on LTL shipments. Over 30% of LTL shipments are reclassified after pickup, resulting in average surcharges of $85 per shipment.

⚠️ Freight Density Disclaimer (Updated May 9, 2026)
