FedEx Maximum 150 lbs. and Shipping Rates

FedEx allows packages up to 150 pounds to be shipped via their Express services. However, the maximum length and girth of a package are specific rules. This applies to both the single side and the entire package.

The single side maximum length for FedEx Express is 119 inches. This is the maximum length for a single side of a package, regardless of its orientation.

The overall maximum length for a package, including its girth, is 165 inches. This is the total length for a package, including its length and girth.

For packages weighing 150 pounds or less, the FedEx Residential Delivery Charge is $6.45 per package. The FedEx Express Delivery Charge is $6.95 per package. Additional Handling surcharges can range from $29.50 to $58.75 based on zone, weight, or dimensions.

Oversize charges apply if a package exceeds 96 inches on its longest side, 130 inches in length plus girth, or weighs over 110 pounds.

Packaging and Fulfillment Supply Costs

As a small e-commerce business, you need to understand the current costs and regulations associated with packaging and fulfillment. Here are some key facts to keep in mind:

• The cost of packaging can vary from $0.15 to $4.00 per unit for mailers and shipping boxes combined, depending on the order quantity and custom printing.
• Shipping charges may be exempt in some states if they reflect actual delivery costs.
• Fulfillment fees for standard-size items range from approximately $2.29 to $7.46, depending on size and price band.
• Holiday peak fees add roughly $0.32 per unit from October 15, 2026, through January 14, 2027.

When calculating your packaging and fulfillment costs, it's essential to consider the shipping carrier, volume, and weight of your packages.

USPS Maximum 70 lbs. and Shipping Rates

The United States Postal Service (USPS) allows for the combined length and girth of a package to be up to 108 inches for Priority Mail and Priority Mail Express services. This means that packages with a combined length and girth of 108 inches or less can be sent via USPS at a lower rate.

However, if the combined length and girth exceeds 108 inches, the package will be considered oversized and will be charged a higher rate. For example, packages between 108 and 130 inches will be charged at an oversized price.

In addition to the combined length and girth, the weight of the package also plays a role in determining shipping rates. USPS Ground Advantage allows for parcels with a combined weight of up to 130 inches to be sent at a discounted rate, with parcels between 108 and 130 inches charged at an oversized price.

For standard shipping boxes, the cost varies depending on the weight and size of the box. The cost of a standard shipping box can range from $0.80 to $2.50 per unit, depending on the size and weight of the box.

This surcharge will be added to the total cost of shipping, and will be based on the weight and size of the package.

USPS and FedEx Shipping Surcharges and Fees

The shipping carrier's ability to charge additional fees has become a crucial factor in determining the total cost of packages for small e-commerce businesses. As of July 12, 2026, the USPS DIM divisor changed from 166 to 139, which means that packages larger than 1 cubic foot now round up to the next whole inch. This change has a significant impact on packages weighing between 1-100 pounds.

In addition to the DIM divisor change, FBA fees have increased by an average of $0.08 per unit sold, effective January 15, 2026. This means that businesses selling through the FBA program may need to adjust their pricing accordingly to ensure they are not overpaying for shipping.

Another important aspect to consider is the added fees for high-priority and expedited shipping options.

It is essential for small e-commerce businesses to be aware of these changes and how they will impact their shipping costs. By understanding the new rules and fees, businesses can make informed decisions about their shipping strategy and adjust their pricing to ensure they are in compliance with the regulations.
