Submit the correct system for each product. If you have different products each with different size systems, make sure to submit the correct size system. If you don’t submit a size system, we’ll use the standard system for your target country, which might not be right for your product.
Submit the size attribute. Along with the size system, make sure to submit the specific size of your product using the size attribute.
Submit the size_type attribute if relevant. If your product also has a size type, submit the size_type attribute.
