This tutorial is going to show you how to change the number of related products in WooCommerce.

You already know how to set up related products. We will show you how to change number of related products in this tutorial.

Please, follow steps below to change related products number:

1. Connect to your server using FTP or hosting Cpanel.

2. Locate file called shop-functions.php in wp-content/themes/theme#####/includes folder (where ##### is your theme number).

3. Modify lines 80-97:

   //Related products limit
   function tm_related_products_limit() {
   	global $product;
       $orderby = '';
   	$columns = 4;
   	$related = $product->get_related( 4 );
   	$args = array(
   		'post_type'           => 'product',
   		'no_found_rows'       => 1,
   		'posts_per_page'      => 4,
   		'ignore_sticky_posts' => 1,
   		'orderby'             => $orderby,
   		'post__in'            => $related,
   		'post__not_in'        => array($product->id)
   	);
   	return $args;
   }
   add_filter( 'woocommerce_related_products_args', 'tm_related_products_limit' );

4. Change $related = $product->get_related( 4 ); number to the number of related products you would like to be shown on your site.
