WooCommerce includes settings to change the width of product images for the Main Image and for Thumbnail images. There are specific Avada settings which work in conjunction with your WooCommerce images sizes. When configuring these image size settings, it’s important to take into account the Avada theme settings as well. We’ll touch on each of these settings in detail below.
Note: If the images you’re uploading for your products are smaller at the source than the image sizes set in your WooCommerce settings, you may see some visual layout discrepancies on the frontend of the shop pages. This is not a bug. It is simply because your images were too small for WooCommerce settings to affect them. You can think of these settings as a max width and height for your images. Anything below the limit will not be resized.
While setting up your shop, be sure the WooCommerce image size settings and the actual size of your images are considered. In summary, your images should be equal to or larger than your WooCommerce image size settings
After any changes to your image size settings, you’ll need to regenerate your thumbnails for it to affect images already uploaded to your site. We recommend using the Regenerate Thumbnails plugin. Please see the steps below for details on changing WooCommerce image sizes.
