Clothing Size Standards
Standardization of clothing sizes is part of a larger initiative to improve the overall shopping experience via incorporation of consistent and accurate data. In 2020 (2H20), Amazon is introducing a new set of attributes specific to clothing sizes that will be used to display standardized and consistent size values to on-site customers.
We highly encourage all sellers to begin adopting the new standards and to proactively update clothing sizes that do not conform to future requirements. In addition, we recommend that sellers spend time reviewing the standards outlined below and the Frequently Asked Questions. To ensure that your clothing sizes are displayed properly on the website, we ask that you include the following information for each clothing size that you submit.
The following tables provide detail about the compliant size values for clothing products.
