Could you please tell me which size should have featured images for the blog posts, so they don’t look blured when they are displayed in the bottom of the home page? I found some topics about it in this forum, but there are different numbers and the topics are several years old.
The featured image size depends on the width of the content column, which changes according to the container width and columns layout that you have set in the theme’s customizer.
In the default out-of-the-box configuration of two-column layout with container width set to 1170px, the featured image width is 750px. There is no set height so it will preserve the original aspect ratio of the image while adhering to the width limit.
