If your product range includes items that come in different sizes and colors, it's important to consider setting up variants to help customers find the products they need. Variants allow you to create unique combinations of attributes for each product, making it easier for customers to select the right size and color for their needs.
For instance, let's say you sell t-shirts in various sizes and colors. You might have three size options: small, medium, and large, and two color options: blue and red. Using variants, you could create a unique combination for each t-shirt, such as a small blue t-shirt or a medium red t-shirt.
To add variants while you're adding a product, go to the Add product page, and click the Color & Sizes tab.
This option lets you specify different prices and stock for your product variants.
