Amazon will be standardizing the listing creation process for ASINs in the Apparel category starting in summer 2020. The standardized apparel sizes will allow us to display a clean and well-organized dropdown list of available sizes on our website, providing a better shopping experience for customers.
Apparel sizes that do not meet the new standards may be removed from display on detail pages after June 30. This applies to newly-created ASINs as well as existing ASINs. Therefore, we highly encourage all selling partners to begin adopting the new sizing standards and to proactively update apparel sizes that do not satisfy future requirements immediately.
To see guidelines and adjust your sizes to meet our standards, please go to the Seller Central help page and view compliant size values for Apparel products.
