What is My Freight Density? XPO Calculator 2026

Our freight density calculator uses the official 2026 NMFC standards to determine exactly what your freight density is and which freight class applies to your shipment. Simply enter your dimensions and weight, and we'll calculate:

Why Knowing Your Freight Density Matters in 2026

With LTL carriers tightening density requirements, knowing your exact freight density can save you 15-25% on shipping costs. Here's why:

✅ Correct Classification

Wrong density = wrong class = reweigh fees up to $75 per shipment + higher rates.

💰 Accurate Quotes

Get precise quotes upfront instead of surprise adjustments later.

📦 Optimized Packaging

Reduce dimensions to improve density and lower class.

🚚 Carrier Selection

Some carriers specialize in specific density ranges.

2026 Freight Class by Density (NMFC Standards)

Dimensional Weight (DIM) Explained for 2026

Density Range (lb/ft³)	Freight Class	NMFC Category	Common Examples
≥ 50	Class 50	Dense	Steel, machinery, bricks
35 - 49.9	Class 55	Medium-Dense	Ceramic tiles, auto parts
22 - 34.9	Class 60	Medium	Furniture, appliances
15 - 21.9	Class 70	Medium-Light	Boxed goods, electronics
8 - 14.9	Class 92.5	Light	Clothing, books
5 - 7.9	Class 125	Very Light	Empty boxes, plastics
3 - 4.9	Class 175	Bulky	Furniture, ping pong tables
1 - 2.9	Class 250	Very Bulky	Pillows, sleeping bags
< 1	Class 400	Extremely Bulky	Lampshades, foam products

Understanding dimensional weight is crucial for accurate freight pricing. Here are the 2026 DIM factors:

❓ Frequently Asked Questions About Freight Density (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. Use our calculator above to see your exact class based on density.

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. Density = Weight (lbs) ÷ Cubic Feet. All carriers use this standard formula.

What's the DIM factor for 2026 LTL shipments?

The standard LTL DIM factor for 2026 remains 139. For parcel shipments, DIM factor is 166. Dimensional Weight = (Length × Width × Height) ÷ DIM Factor. Billable weight is the greater of actual weight or dimensional weight.

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. Our calculator helps you avoid these costly adjustments.

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). Check our full table: 50+ = Class 50, 35-50 = Class 55, 22-35 = Class 60, 15-22 = Class 70, 8-15 = Class 92.5, 5-8 = Class 125, 3-5 = Class 175, 1-3 = Class 250, <1 = Class 400.
