See new size attributes for listing your apparel products
Amazon is standardizing Apparel sizes to improve the overall customer shopping experience through ingestion of consistent and accurate data.
Starting September 29, 2020, new size attributes for listing pants, shorts, overalls, socks, underpants, sweatshirt and pajamas product types are available as optional for your listings. Previously, you used free form text to provide apparel sizing information. Now, you will need to select values from a standardized list for size attributes like apparel size, body type, and height type.
These attributes will enhance the customer experience when browsing and viewing your products by displaying standardized and consistent size values.
We encourage you to review details and additional product type release dates outlined on our Help page Apparel Product Listing Experience and related FAQ page
