As a general rule, we recommend using a standard shipping service to ship smaller packages, as the rate is determined purely by the size, maximum weight, and possible long distances it needs to travel. SFL Worldwide makes it easy for our users to get discounted rates for small and large flat rate box shipping and standard shipping with our intuitive rate calculator that gets quotes from some of the best carriers in the industry, such as DHL, UPS, and FedEx within seconds. Use our instant rate calculator to find a USPS Priority Mail Express standard or flat rate plan that suits your needs.

Unlike Flat Rate Shipping, regular or standard shipping calculates rates based on a package’s weight, size, destination, and service to determine your shipping prices. Flat Rate Shipping, as the name suggests, offer a fixed and flat rate for all shipments, irrespective of their size or weight. And when shipping packages, select First Class Large Package.Shipping methods have their own advantages and disadvantages. We suggest you review your shipping process to keep your larger packages in the smallest box possible to avoid these surcharges. * Starting April 3, 2022, the USPS is adding new surcharges for large packages: That is the exact cubic dimension of your package. Multiply the Length, Width, and Height, and then divide that total by 1,728. For boxes that aren't square, measure the Length, Width, and Height of your box in inches.

A 2 cubic foot square box is pretty big and well beyond the size of most packages being shipped. A square package 2 feet by 2 feet is 2 Cublic feet. A square package 1 foot by 1 foot is 1 cubic foot. * Calculating the cubic dimensions of your packages isn't difficult. And when shipping packages, select Large Package. * Does not apply to First Class and Media Mail.
