Show fewer tags in WordPress

Your WordPress website probably just started growing and it has a lot of tags. Some website designs might start looking out of sync with that big, messy list inside the WordPress tag cloud widget. If you would rather still show a number of tags instead of removing them, here’s how:

//Adds a filter callback
add_filter('widget_tag_cloud_args', 'tag_widget_limit');
 
//This will limit the number of tags
function tag_widget_limit($args){
 
 //Checks if taxonomy option inside widget is set to tags
 if(isset($args['taxonomy']) && $args['taxonomy'] == 'post_tag'){
  $args['number'] = 20; //The number of tags displayed now
 }
 
 return $args;
}

Just go inside your theme’s folder and paste the code at the end of your functions.php file.
