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.

When to use

Optional for each product

If you submit a size through the size [size] attribute, then also submit the size system [size_system] attribute to explain which system you're using.

Guidelines

Follow these guidelines to make sure that you submit high quality data for your products.

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 on the Diagnostics page of your Merchant Center account.

  • Ensure that you only use this attribute if you are sure that your product doesn't have any assigned unique product identifiers. 
  • Products for which the identifier_exists [identifier_exists] attribute is incorrectly set to no [no] or false [false], and for which there is evidence that a unique product identifier exists, will be disapproved.

Best practices

These best practices can help you 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.
