Steps to set limit for the WordPress Tag Cloud

  • Login to WordPress

  • Select the correct theme to edit
    If you are using a Child Theme, make sure your child theme is selected here.
  • After you have selected the theme to edit, click on THEME FUNCTIONS file (functions.php). 
    If this file is not present, you need to create one from your host file manager.
  • Copy and paste the following lines of code in the functions.php within <?php and ?>
    //Register tag cloud filter 
    add_filter('widget_tag_cloud_args', 'tag_widget_limit');
    
    //Limit number of tags inside widget
    function tag_widget_limit($args){
    
     //Check if taxonomy option inside widget is set to tags
     if(isset($args['taxonomy']) && $args['taxonomy'] == 'post_tag'){
      $args['number'] = 10; //Limit number of tags
     }
    
     return $args;
    }
  • Change the number of tags to display in the code above near ‘//Limit number of tags' as per requirement.
