For optimized use of the styles in the Frankfurt theme, we recommend using images of at least 1500 x 1500 px in your blog and shop section.

WordPress automatically generates the smaller images for thumbnails and previews from that size.

Important: Have you got some images stored in your image library yet? Use the plugin Regenerate Thumbnails to regenerate the image sizes after you have installed the theme.

Important: Frankfurt automatically assigns product image sizes, and will overwrite the settings you specified under WooCommerce → Settings → Products → Display → Product Images during uploads. You can change this behavior via a child theme if you use a filter.
