Apparel Product Listing Experience

Amazon is standardizing apparel sizes to improve the overall customer shopping experience through consistent and accurate data. Amazon has introduced new Apparel Size Standards, which set sizes based on industry standards. Previously, selling partners used free text to provide apparel sizing information. Going forward, this will be replaced with size attributes, such as body type and height type, which will only allow you to select values from a standardized list. Standardized size values will enable customers to view consistent sizes across apparel products, thereby providing an enhanced browse and search experience.

Amazon will roll out new apparel size attributes in waves across product types. We encourage all selling partners to begin familiarizing themselves with the details outlined below and those included on our FAQ page.

Apparel size attributes and requirements

After you select values for these two attributes, a specific set of values will populate for the attributes listed in the following section.

• Target Gender: Select the gender for which the product is intended.
  • Valid values: Masculin, Féminin, Unisexe
• Age Range Description: Select the age range for which the product is intended.
  • Valid values: Adulte, Enfant, Bébé, Enfant de moins de 5 ans

Size attribute examples and details

Using the separate fields that exist for each of the individual apparel size attributes, they will be automatically combined into a customer-friendly format once the required sizing information has been designated. The combined attributes will be displayed on the detail page as in the examples below:

For certain apparel products, the new apparel size attributes will appear with different attribute-specific prefixes and include additional size attributes to accommodate the product type needs. For example, for the Shirt product type, Apparel Size Class will appear as Shirt Size Class and additional attributes like Neck Size Value and Sleeve Length Value will be available. Requirements for using these attributes will follow the same guidance under the Product-type specific attributes table above. The tables below illustrate how each product-type specific attribute will populate and result in the customer-facing size value.
