The Cheapest Ways to Ship Large Boxes Across the US

Understanding Large Box Shipping Options Across the US

The cheapest ways to ship large boxes across the US hinge on weight (up to 150 lbs for FedEx/UPS), dimensions (under 165″ girth), and zones (1-8 distance bands)—with ground services like USPS Retail Ground or UPS Ground edging express for non-urgents. 2025 updates include USPS’s $0.05-0.10/lb increases, favoring flat-rate for dense loads.

Use Case: A Chicago retailer ships 40-lb furniture via UPS Ground—arrives Seattle in 4 days at $45, vs. $120 Priority Express.

Checklist for Large Box Prep:

  • Max 70 lbs USPS; 150 lbs UPS/FedEx.
  • Girth <165″ (L+2W+2H).
  • Declare value for insurance ($100 free).
