Most products online are available in different colors, sizes, materials, and price points. These buyings options are product variants.
Shopify product variants offer customers different buying options for a product. On Shopify, you can add up to 100 variants (for example, different colors) per product and three customized choices (for example, color, size, and material). Your customers choose the variant they need from the options you have available.
When you create a new variant for your product, you can change the product’s price to suit each variant. Also, you can make other changes, like inventory and shipping options.
Options may differ depending on the product. For example, one product may allow buyers to select sizes, colors, and materials, while a different product in your store may have the options of flavor or style.
Each variant on Shopify has a unique stock-keeping unit (SKU), allowing you (and any third-party warehouse or shipping provider) to correctly identify every unique item in your catalog.
