How to add Product Specifications in WooCommerce?

To add product specifications, use Product Attributes and the Additional Information tab. Edit the product, scroll to Product data, and open the Attributes section. Add attributes such as Material, Size, Weight, Power, or Compatibility, then enter values (or create global attributes in Products → Attributes for reuse). Tick “Visible on the product page,” and save. WooCommerce automatically shows these specs in the Additional Information tab and can use them for filters and variations. If you want a dedicated “Specifications” block or a formatted table, install a product tabs/specifications plugin, then create a custom tab and paste your spec list there.
