Reply To: How to make a flat product grid?

Hello,

There are two ways only: upload equal size images or crop them. No more option in our theme or in Woocommerce.

You can alternatively try this СSS:

.product-grid-item .product-image-link img, 
.product-grid-item .hover-img img {
	max-height: 250px;
	object-fit: contain;
}

Best Regards
