Hello,
It is recommended to use a graphics editor and prepare product images (make them the same size) before uploading images to your media gallery. For example, these images have different dimensions – https://prnt.sc/l7n86nLVIbXl https://prnt.sc/uAEtPXcSO7bk
Please read this article – https://xstore.helpscoutdocs.com/article/89-product-images
Then, go to Appearance > Customize > WooCommerce > Product Images > thumbnail width > set 360, Uncropped and regenerate thumbnails using plugin
This is independent of the theme, settings for images come from WooCommerce plugin, if our recommendation doesn’t suit you, contact support of WooCommerce.
Regards
