Every online business owner knows the importance of having a visually-appealing website for their customers. If you’re running an online store with WooCommerce, you might want to showcase your products in high-quality images on your website.

In this blog post, we’ll guide you through the process of changing your product gallery image size in WooCommerce.

Step 1: Adjust your theme settings

Before making any changes to your product gallery image size, you need to check your theme settings. Some themes have specific image size requirements that need to be followed.

Step 2: Define your image sizes

To change your product gallery image size in WooCommerce, you need to define your image sizes. Go to your WordPress dashboard and navigate to Settings > Media. You’ll find three default sizes for your images, but you can change them according to your preference. Enter your preferred dimensions for your product gallery image size and click Save Changes.

Step 3: Regenerate thumbnails

After defining your image sizes, you need to regenerate your thumbnails to update your existing product images. You can use a plugin like Regenerate Thumbnails to do this. Install and activate the plugin, and then navigate to Tools > Regenerate Thumbnails. Click the Regenerate All Thumbnails button to start regenerating your images. This process might take some time, especially if you have a large number of product images.

Step 4: Change your product gallery image size

Now that you’ve defined your image sizes, you can change your product gallery image size in WooCommerce. Go to your WooCommerce settings and click the Products tab. In the Product Images section, you’ll find the option to change the image dimensions. Enter your preferred dimensions and click Save Changes.

Step 5: Check your product gallery images

Once you’ve changed your product gallery image size, you need to check your online store to make sure that your product gallery images appear in the correct size and resolution. Visit your website and go to a product page to check your product gallery images. If you notice any issues with your images, go back to your image settings and make the necessary adjustments.


Changing your product gallery image size in WooCommerce can make a huge difference in the visual appeal of your online store. Follow these five easy steps to improve the quality of your product images and make your online store more attractive to your customers. However, keep in mind that changing your image size settings might affect your website’s loading speed, so make sure to optimize your website’s performance by using a caching plugin or a content delivery network.
