Reply To: Optimal photo size for shop

Hello,

It depends. If you set images on a background of big blocks, images would be bigger. Some of the product pages have width: 870px; height: 1110px;

Some of the backgrounds 900 x 1900 px.

You can test a couple to understand. Also, it depends on the type of product which you are going to sell if it has any peculiarities or not.

You can configure product images in Appearance > Customize > Woocomerce > Product image.

Best Regards
