Size is known as one of the most common variations that we often encounter for a product. This would be extremely helpful for those who sell clothing items that require customers to know their size before they make a purchase, so you need to add a custom size chart to your product page.

For example, there are some options that your product’s size can include: Small, Medium, Large, or XL. Additionally, when you input sizes for your product, you must change the way that you set their product details. If you have different prices for different sizes, you need to adjust those settings for each variant from the variant details page as well. Also, you are able to manage inventory for each variant from the Inventory page at your disposal.
