By submitting consistent sizes, you can help ensure that the size is standardized correctly. The size that you submit is standardized before it’s shown to users. For those variants, submit 'S', 'M', and 'L'. For example, imagine you’re selling a shirt that comes in small, medium, and large. The values that you provide could be shown to users, so make sure that values you submit can be understood by your users. Provide values that your users will understand.Sizes for different types of products vary widely, but providing this information can help ensure that your product is shown to the right users. For non-apparel products, submit the relevant size.For example, enter 16/34 to represent a neck size of 16 inches and a sleeve length of 34 inches. Instead, condense multiple dimensions into one size value using a slash.

For products with multiple dimensions, don’t submit multiple sizes separated by a comma ( ,).For example, enter 'small/medium/large' (and not 'small, medium, large'). Don’t submit multiple sizes separated by a comma (, ).Also submit each variant as a separate product with the same value for the item group ID attribute. For example, use “S” as the value for a 'small red T-shirt' and use “L” as the value for a 'large red T-shirt'. For apparel products, use this attribute when your product is a variant that is distinguished by its size.Submit this attribute for all products that vary by size.Make sure to submit non-size information through the correct attribute, such as color, material, and pattern.Don’t submit values such as 'n/a', 'none', or 'multisize'. Additional size attributes will be discarded, and you will receive a warning. If you provide multiple size attributes for the same product, only the first will be applied.

Submit only one attribute per product.
