Size setup attributes

- Common Attribute

"size..value": This attribute can be used to provide the main size of your product. 

- Category-Specific Attributes

Depending on the product category, additional size attributes might be required. 
Complete these attributes for your clothing products (valid values differ for each country):

• "target_gender..value" (required): Gender for which the product is intended. Possible values: "Female", "Male", "Unisex".
• "age_range_description..value" (required): Age range for which the product is intended. Possible values: "Adult", "Kid", "Toddler" (1-3 year of age), "Infant" (0-1 year of age).
• "size_system" (required): Country code corresponding to the selling country, used to display local sizes. Examples: "UK", "FR/ES".
• "size_class" (required): Type of clothing sizes. Examples: "Age", "Alpha", "Numeric".
• "size" (required): Clothing size value. Examples: "40", "S", "6 Months".
• "size_to" (optional): Use only if providing a range of sizes for a product. Select the ending clothing size range value. Examples: "42", "M", "12 Months".
• "body_type" (conditionally mandatory): Applicable body type. May not be required for specific products or age range descriptions. Examples: "Regular", "Plus".
• "height_type" (conditionally mandatory): Applicable height type. May not be required for specific products or age range descriptions. Examples: "Regular", "Tall".
   

Please note that the names of the "size", "size_system", "size_to", "size_class", "body_type" and "height_type" attributes vary depending on the product type.
Example: for pants, you will fill in the "bottoms" attributes ("bottoms_size.size", "bottoms_size.size_system", etc.).

Lengow Tips

• Always ensure logical consistency between age range and size.
  For example, a size labeled "Infant" shouldn't have a size value like "XXL".
• Do not populate size-related attributes for parent products.
• Use classification rules based on your sizing format (numeric, age, alphabetical).
• If unsure, test your configuration with sample products to verify no errors are returned from Amazon.
