WooCommerce product variations let you sell one product in multiple versions – different sizes, colors, or materials – from a single product page, instead of creating a separate listing for each option. A T-shirt in three sizes and four colors becomes one product with up to 12 variations, each with its own price, stock, SKU, and image.

This guide walks through the native WooCommerce setup step by step, the mistakes that trip up most store owners, and where the built-in dropdown starts to fall short.
