By default, Jupiter X doesn’t have option to change the number of related/recommended posts inside the single posts pages. It will calculated the number of related posts based on the layout you chose. 3 related posts for when you have one sidebar, and 2 related posts for when you have two sidebars. Also, 4 posts for when you don’t have no sidebar (full width).
Tip: Use Growmatik to show personalized blog lists based on user behavior and history without touching Jupiter X settings.
However, you can easily change that number by adding this snippet to your child theme’s functions.php file:
add_filter( 'jupiterx_post_related_count', function() {
$post_count = [
'posts_per_page' => 2,
'columns' => 6,
];
return $post_count;
} );
The columns value inside the $post_count array is the number of Grid columns. So, setting it as 6, will actually give you two columns. (number of grid cells is 12)
