To fix WooCommerce product image size issues, start by checking your image settings. Go to WooCommerce → Settings → Products → Display and review image dimensions. Next, go to Appearance → Customize → WooCommerce → Product Images and adjust thumbnail and main image settings. After changing sizes, regenerate thumbnails using a trusted plugin. Also, check your theme, as some themes override default image sizes. Clear your cache after updates. Upload images larger than required, so WooCommerce can resize properly. Consistent image dimensions help prevent stretching, blurring, or cropping issues.
