Certain products, especially those classified as oversized or with unique storage requirements, may require providing packing dimensions. In this case, you will be prompted to add them while listing the item.
If your product requires packing dimensions, follow these steps:
Select the appropriate weight unit (e.g., pounds or kilograms) and enter the correct package weight.
Choose the dimensions unit.
Enter the width, height, and length of the package. These values must be greater than zero, as shown in the image below.
Product dimensions and volume are critical inputs to determining the product size tier. Along with product weight, dimensions are used to calculate a variety of FBA fees, including storage fees, fulfillment fees, and returns processing fees.
