Product size tiers for Seller Flex

Seller Flex fulfillment fees are based on the weight and dimensions of the packaged item – known as the product size tier.


Standard-size versus oversize

A standard-size item is one that, when fully packaged, 12 kg or less and does not exceed:

  • 45 cm on its longest side
  • 34 cm on its median side
  • 26 cm 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.

Determine the product size tier for your item

To determine the correct tier for your item, find the row in the table below with measurements that do not exceed the weight or the dimensions of your item.

Use the larger of either the single unit weight or the dimensional weight. The dimensional weight is equal to the unit volume (length x width x height) divided by 5,000.
