Hello,

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 are some of the popular aspect ratios (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.

Best Regards.
