Minimum requirements

These are the requirements 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 you submit can't be used.

Best practices

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

• Submit this attribute for all apparel 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 to 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 to 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.
