Hello,

You asked about the image dimensions and I told you that.

Sorry, but there is no option in Theme Settings to adjust it.

I have visited your website and the icon size is small on your website. To increase it Please try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.

.hasno-product-count .category-nav-link .category-icon {
max-height: 35px;
}

If you want to ask anything else then provide with some relevant screenshot of the specific area to check it myself and help you out accordingly.

Regard’s.
Xtemos Studio.
