Page featured image not showing on home page

I think you’d need to get the actual page object and find the ID from there. Then, you can pass that ID to the_post_thumbnail(), otherwise I think the ID of a post in the loop will be used, not the actual home page. Try this $page_object = get_queried_object(); to get info about your home page.

Thumbnail size according to width and height

Using lower resolution/size images for thumbnails on posts index

You will have to edit your theme files for that, but you can use the_post_thumbnail (Codex) to show the featured image in a smaller size. This is an example from the Codex which you can probably use 1 to 1: <?php if ( has_post_thumbnail() ) : ?> <a href=”https://wordpress.stackexchange.com/questions/189741/<?php the_permalink(); ?>” title=”<?php the_title_attribute(); ?>”> <?php … Read more
