Product size tiers

Determine if your products are Envelope, Standard-Size, or Oversize

A packaged Unit with the following weight and dimensions is an Envelope:

  • 500 g or less
  • 38 cm or less on its longest side
  • 27 cm or less on its median side
  • 2 cm or less on its shortest side

A packaged Unit with the following weight and dimensions is Standard-Size:

  • 9 kg or less
  • 45 cm or less on its longest side
  • 35 cm or less on its median side
  • 20 cm or less on its shortest side

A Unit exceeding any of these measurements is Oversize. As of September 13, 2021, the Oversize size tier is divided into the following size tiers:

Size tier Maximum unit weight (kg) Longest side (cm) Median side (cm) Shortest side (cm) Length + girth (cm)
Small oversize Up to 32 kg Up to 152 cm Up to 76 cm Not applicable Up to 330 cm
Medium oversize Up to 68 kg Up to 270 cm Not applicable Not applicable Up to 330 cm
Large oversize Up to 68 kg Up to 270 cm Not applicable Not applicable Up to 419 cm
Special oversize Over 68 kg Over 270 cm Not applicable Not applicable Over 419 cm
Note: Any packaged unit that is over 9 kg or with a longest side over 45 cm, its shortest side over 20 cm, or its median side over 35 cm is oversize.
Note: If a product is sold as a set, use the dimensions and weight of the combined Units when packaged together.
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 that the fee is calculated.

Oversize Special Handling

An additional fee will be applied to large-screen televisions* and other products that meet these criteria:

  • Exceed 270 cm on the longest side; or
  • Exceed 419 cm for the longest side + 2x height + 2x width; or
  • Exceed an outbound shipping weight of 68 kg

*Large-screen televisions refer to TVs with screens 106.7 cm or larger. However, smaller televisions could qualify for the Special Handling surcharge based on other factors such as weight and how delicate the TV is.

Change a product's weight or dimensions

When you are the only seller of an ASIN, and you have to change your product's weight or dimensions, contact Selling Partner Support and explain that you have 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 are shown.

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, the weight and dimensions information may not represent your specific units.
