Product Options: Size


The size display type is used to show the available sizes of a product. It’s commonly used for products that are available in different sizes, such as clothing, shoes, or food.

This option will use a rectangle display type. If you prefer to display your sizes in a drop-down or radio buttons, check out Product Options: Multiple Choice.

Use Product SKUs to add specific details about your different size variants, like different product photos, prices and weights.
