Houston, Texas, to Seattle, Washington, stretches approximately 2,340 miles, crossing through the mountain states and into the Pacific Northwest. Packages typically route through hubs in Denver, Salt Lake City, or along the I-5 north corridor. This long-distance lane falls into the highest USPS shipping zones, making flat-rate options and carrier selection critical for managing costs.

Cheapest Option by Package Size
- Small packages (under 1 lb): USPS First-Class Mail or Ground Advantage starts at ~$5.00–$6.80. This remains the most affordable tier even at cross-country distances.
- Medium packages (1–5 lb): USPS Priority Mail ranges from
$11.50–$17.00. The Flat Rate Medium Box ($17.10) provides predictable pricing that often beats calculated rates. - Heavy packages (5–20 lb): USPS Priority Mail Large Flat Rate Box (~$23.00) is a strong value. UPS and FedEx Ground range from ~$22.00–$40.00 and offer dimensional weight pricing that can work in your favor for light, bulky items.
- Large or oversized items (20+ lb): UPS and FedEx Ground range from ~$42.00–$75.00. Items exceeding 70 lb should be evaluated for LTL freight, which lowers per-pound costs substantially on long routes.
Delivery Time Comparison
| Speed | USPS | UPS | FedEx |

Ground shipping takes most of a business week on this 2,340-mile route. USPS Priority Mail cuts 1–3 days off ground delivery for a modest premium, making it the practical middle-ground option.
Tips for This Route
- Always price flat-rate boxes first. At zone 8 distance, calculated USPS rates spike. Flat Rate boxes lock in a price that ignores the 2,340-mile gap, saving significantly on packages over 2 lb.
- Plan around Pacific Northwest weather. Seattle receives heavy rain from October through April. Use waterproof poly mailers or sealed inner bags for moisture-sensitive items like paper goods, textiles, and electronics.
- Build in a transit buffer. Long-distance ground shipments cross multiple sorting facilities and state lines. Add 1–2 extra days to published estimates when planning delivery commitments, especially during Q4 holiday surges.
- Evaluate 2nd Day Air for time-sensitive items. UPS 2nd Day Air at ~$32.00 can be worth the premium when delayed delivery would cost more in customer dissatisfaction or operational disruption.
