Represents the primary size designation of a product or variant.

The size attribute contains the specific size value for products such as apparel,
footwear, accessories, or any other sized merchandise.
Size values can be numeric (e.g., "8", "10.5"), alphabetic (e.g., "S", "M", "L", "XL"),
or descriptive (e.g., "Small", "Medium", "One Size"). This attribute is critical for
variant differentiation, search functionality, and product selection across all
applications.

General Usage

• Size-based variant selection and differentiation

• Size filtering and faceting in product listings

• Size recommendation and fit guidance

• Search and navigation by specific sizes

Examples

"XL"

"9.5"

"32x34"

In Discovery, size values are automatically converted to lowercase during processing to
