Apparel size standards

Standardization of apparel sizes is part of a larger initiative to improve the overall shopping experience through ingestion of consistent and accurate data. In 2020 (2H20), Amazon is introducing a new set of attributes specific to apparel 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 apparel sizes that do not conform to future requirements. Additionally, we recommend that sellers spend time reviewing the standards outlined below and the Frequently Asked Questions.

To ensure your apparel sizes display properly on the website, you need to include the following information for each apparel size you submit.

The following tables provide detail about the compliant size values for apparel products.

Important: Syntax and letter case must be exactly as described in the examples below.
