So, in this article, we will be discussing how to calculate the cheapest shipping charge to ship your large packages with an advanced shipping calculator tool.

To pack the items in a perfectly fitting box and calculate the shipping cost, you need to measure the length, width, and height of the items.

Large packages could often be electronics, furniture, or any fragile items. In such cases, you have to pack the items carefully in a best fitting box with cushioning materials inside to protect the items.

  • Check the weight of your packages

As you know, the weight of the product has a major role in determining the shipping cost. The heavier your packages are, the higher the shipping charge will be. Hence, in order to ship the large packages domestically and internationally, you have to weigh the items precisely to calculate the shipping cost of various shipping carriers.

The shipping label contains the relevant information for the carriers to deliver your products to the right person in the exact location. Also, it will contain a barcode which is mandatory to be present on the shipping label. 

  • Paste the shipping label and seal the package

After generating the label, you have to paste it outside of the package. Also, do not forget to use quality tapes to seal the package.

Sometimes you may need to send the large packages to the shipping carrier office or their hub to get them shipped. But, popular shipping carriers provide pickup facilities. In such cases, you can make your packages ready to ship and wait for the pickup person!

Well, these are the steps to ship the oversized packages. Now, let us check what is an ‘oversized’ package for the popular shipping companies USPS, UPS, FedEx, and DHL.


If the combined length and weight of the package are more than 108 inches and 130 inches, the package is considered oversized in USPS. If your package’s measurement values are greater than these values, you need to contact USPS to get a special rate for you. Or, you may need to go for the slower services like USPS Retail Ground.

Its Parcel Select can be used to ship packages that exceed 108 inches in length but less than 130 inches in width. 


All packages that weigh more than 150 pounds and have a combined length/width over 165 inches are considered large packages by UPS.

UPS categorizes large packages into 2 categories as Large Package and Over Maximum Limits.


Large Package: They charge normal rates for large packages. And packages with more than 96 inches on their longer side, and/or more than 130 inches when combining length + width + girth are considered as large packages. If the packages exceed 90 pounds, UPS will charge additional charges.

Over Maximum Limits: They use UPS Freight Services for packages that are over maximum limits. This means, the weight will be over 150 lbs, and dimensions will be 108 inches on one side, or exceeding 130 inches as combined length + width + girth. 


All packages that weigh more than 90 pounds are considered large items in FedEx. Also, if the length/width exceeds 130 inches and 96 inches, it will be a large package for FedEx. FedEx large packages are comparatively smaller than large packages of USPS and UPS.

You might need to use the International Ground Services and US Express Package option to ship the large packages internationally and domestically. For shipping the large packages with these services on holiday seasons, you have to pay additional charges than usual.


All packages that weigh over 70 kilograms or 155 pounds are large items for DHL. Also, if the dimensions exceed 120 cm x 80 cm x 80 cm or 47 in x 31 in x 31 in. As DHL mainly focuses on international shipping, they prefer you to contact them directly for getting better quotes for shipping large packages internationally.

These are the meanings of ‘large packages’ or ‘oversized’ packages for the popular shipping carriers.
