SFP Item Size, Weights and Dimensions
Standard-size versus oversize
A standard-size item is one that, when fully packaged, weighs 20 lb or less and does not exceed:
18 inches on its longest side
14 inches on its median side
8 inches on its shortest side
Any item exceeding these dimensions is considered oversize.
Important: If a product is sold as a set, the weight and dimensions are the combined total of all of the items in the set packaged together.
As a SFP Seller, you can go to Manage Seller Fulfilled Prime page to view your product’s size-tier classification (Column: Size Tier) and packaged weights and dimensions (Column: Item Package Dimensions). In the Item Package Dimensions column, longest side of the product will be displayed as length, median side as width and shortest side as height.
