Amazon is standardising clothing sizes which they say will improve the overall customer shopping experience through ‘ingestion of consistent and accurate data’. Previously, merchants used free text to provide clothing 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 standardised list.
From the 22nd of February 2021, you will be required to use these standardised size attributes when creating new listings and updating existing listings.
I have to say I’m massively in favour of this – there’s nothing worse than a garment arriving just to discover that the sizing is Chinese and it’s practically child size in the UK (and I imagine the reverse is also true).
It’s worth pointing out that sizing is specifics to the country site you are listing on. The first attribute to set is the “Clothing Size System” and the Clothing Size System is associated with the selected marketplace (e.g. UK for the UK and US for Amazon.com). This will set the options available, for instance for ‘Body Type’ in the UK options are ‘Regular, Plus’, whereas for the same attribute in the US options additionally include ‘Big’ and ‘Husky’.
“Previously, sellers used free-form text to provide apparel sizing information. Now, you must select values from a standardized list for size attributes like apparel size, body type, and height type for DRESS, SWEATER, BLAZER, SWEATSHIRT, COAT, VEST, ROBE, TIGHTS, KURTA, TUNIC, TRACK_SUIT, PAJAMAS, SOCKS, UNDERPANTS, SUIT, and SALWAR_SUIT_SET. These attributes will enhance the customer experience when browsing and viewing your products by displaying standardized and consistent size values.”
