To customize the height of the product items in the Wrapped Product Skin, you will need to customize the Image Thumbnail Cropping option.
Access Customizer > WooCommerce > Product images and here you should see the 3 cropping options:
- 1:1 – this will keep the box square
- Custom – this one you should use.
- Uncropped – will keep the natural image size. Not recommended.
So to customize the product item height, you will need to select Custom and add the proportion you want, for example:
- 3:4 will make taller height
- 3:5 will make an even taller height
- 4:3 will make the height smaller than its width.
