Product size tiers

Fulfilment fees are based on the weight and dimensions of the packaged item (the product size tier).

Important: For multi-channel fulfilment orders, refer to Fulfilment fees for multi-channel fulfilment orders (may not be available in your region).

Standard-size versus oversize

A standard-sized item is one that, when fully packaged, weighs 9 kg or less and does not exceed:

  • 45 cm on its longest side
  • 34 cm on its median side
  • 20 cm on its shortest side

Any item exceeding these dimensions or weighing more than 9 kg 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 specific 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.

Maximum weights and dimensions for packaged items
Product size tier Weight Longest side Median side Shortest side
Standard size <9 kg <=45 cm <=34 cm <=20 cm
Oversize* <30 kg >45 cm >34 cm >20 cm
* All items weighing more than 9 kg are classified as oversize

It is important to note that packaged Single items cannot exceed the below limits:

Maximum Dimension Limit - 150 cm (Longest side)

Maximum Girth Limit - 300 cm


Maximum Weight Limit - 30 kg

Important: Amazon may verify the weight and dimensions of a product using representative samples. Amazon’s information about a product’s weight and dimensions will be used to calculate fees if there is a difference between Amazon’s information and a seller’s information. Amazon may change its information about a product’s weight and dimensions from time to time to reflect updated measurements. Fees based on the weight and dimensions of a product are calculated using Amazon’s information about the weight and dimensions of that product at the time the fee is calculated.

Change a product's weight or dimensions

When you are the only seller of an ASIN and you need to change your product's weight or dimensions, contact Seller Support and explain that you need to update the measurements. If you currently have inventory for the product, you may need to sell through it before the new weight and dimensions show.

Note: Amazon stores weight and dimensions at the ASIN level. We cannot target a specific unit for measurement. When multiple sellers sell the same ASIN, weight, and dimensions information may not represent your specific units.
