Dimensional weight is calculated based on package size rather than actual weight. For domestic shipments: (Length × Width × Height) / 166. Carriers charge based on whichever is greater: actual weight or dimensional weight.
USPS is often cheapest for small, light packages under 1 lb. UPS and FedEx may be better for heavier items or when speed is important. Always compare rates for your specific package.
Insurance is recommended for valuable items over $100. Basic coverage is often included, but additional insurance typically costs about 1% of the declared value.
Use the right-sized packaging to minimize dimensional weight, compare carrier rates, negotiate volume discounts, offer flat-rate shipping, and consider regional carriers for local deliveries.
