Use a variable product when the item has options, such as different sizes.
- Go to Products → Add New (or edit an existing product).
- In the Product data dropdown, choose Variable product.

- Click the Attributes tab:
- Select Size (or create a size attribute if it doesn’t exist).
- Enter size values separated by a vertical bar, for example:
6 | 8 | 10 | 12 | 14 - Tick Used for variations.
- Click Save attributes.

- Click the Variations tab:
- From the dropdown, choose Create variations from all attributes.
- Confirm when prompted. WooCommerce will generate one variation per size.
- For each variation row:
- Set a Regular price (and Sale price if applicable).
- Set an SKU if needed (e.g. different codes per size).
- Enable Manage stock and set stock quantity if you track stock per size.
- Click Save changes, then click Update for the product.
✅ Tip: Ensure every variation has a price, otherwise the product may not appear correctly on the shop.
