Expanding Product Variations: a Step-by-step Guide to Adding New Size Options to Your Woocommerce Products

In the ever-evolving world of e-commerce, the ability to quickly adapt and update your product offerings is crucial. For online retailers using WooCommerce, one of the most effective ways to meet the changing demands and preferences of customers is by expanding product variations, specifically by adding new size options to existing products.

This guide by Creative Image meticulously prepared for you, walks through the process of enhancing your WooCommerce product listings with additional size variations, ensuring your store remains competitive and responsive to customer needs.


Variety isn’t just the spice of life; it’s a core principle of successful online retail. Offering a broader range of product sizes not only caters to a wider audience but also significantly enhances the shopping experience on your site. Whether it’s adding petite or plus sizes to your fashion line or varying dimensions for home goods, introducing new size options can invigorate your sales and customer satisfaction.


Before proceeding, ensure you have:

  1. Administrative access to your WooCommerce dashboard.
  2. Identified the products in your inventory that require new size variations.

Gathered the necessary information for the new sizes, including dimensions, pricing, and stock levels.

Step 1: Navigate to Your Product Listings

Access Products: Navigate to ‘Products’ on the dashboard menu and select ‘All Products’.

Step 2: Selecting the Product to Update

Attributes Tab: Click on the ‘Attributes’ tab within the Product Data box.

Step 4: Adding New Size Attributes

To create a new attribute, choose ‘Custom product attribute’ and click ‘Add’. Name it ‘Size’ and proceed to add values.

Add New Sizes: In the ‘Value(s)’ field, enter the sizes you’re adding, separated by a vertical bar (e.g., XL | XXL | XXXL for clothing).
