Hello,
WooCommerce lets you resize the product images on Single Product and Shop pages from Appearance > Customize > WooCommerce > Product Images.
Follow these steps to change single product image size:
1. Go to Appearance > Customize
2. Then go to WooCommerce > Product Images
3. Write your desired width in “Main image width” field.
4. Click on “Publish”

Note: Height of single or main product images will remain uncropped and not affected by the cropping settings.
You can define the “height” of the shop thumbnails by setting up the width:height aspect ratio in the “Thumbnail cropping” section:
• 1:1: If you select 1:1, your images will be cropped into squares
• Custom: In Custom you can select the aspect ratio of the image. Here is some of the popular aspect ratio (1:1,
5:4, 4:3, 3:2, 16:9 and 3:1).
• Uncropped: Height of the image will be untouched. Images will display using the aspect ratio in which they were uploaded.
