Size system [size_system]

With the size system [size_system] attribute, you can explain which country's sizing system your product uses. This information helps create accurate filters that customers can use to narrow search results. The sizing system that you submit will affect search, filtering and how variants are shown.

Minimum requirements

These are the requirements that you'll need to meet to show your product. If you don't follow these requirements, we'll disapprove your product and let you know in your Merchant Center account.

  • There are no minimum requirements for this attribute. Keep in mind that you still need to follow the formatting guidelines or the information that you submit can't be used.

Best practices

These best practices can help you to go beyond the basic requirements to optimise your product data for performance.

  • Submit this attribute for all clothing products. By submitting your product's size system, you can help ensure that the size is shown correctly.
  • Submit the correct system for each product. If you have various products with different size systems, make sure that you submit the correct size system. If you don't submit a size system, Google will use the standard system for your target country, which might not be right for your product.
  • Submit the size. Along with the size system, make sure that you submit the specific size of your product using the size [size] attribute.
  • Submit the size type if relevant. If your product also has a size type, submit the size type [size_type] attribute.
  • Submit the gender if relevant. To help show your product in the right search results, also submit the gender [gender] attribute.
