Hello,
The posts having same tags will be displayed as Related posts.
Related posts are presented as a slider and when you hover you will see navigation arrows and all the posts which contain the tag would be presented.
To change the number of related posts to show in a carousel you can copy/paste the single.php file from wp-content\themes\woodmart in the child theme and set the number at the line#56 “‘slides_per_view’ => 2” and save changes.

By increasing the number of posts in the carousel also the size of posts become smaller.
Best Regards.
