You can install a plugin to change the standard tagcloud to your liking, or you can hack the wordpress core file to do this, but let's do it the right way. As for almost everything in wordpress there is a filter for this. So we simply have to create a function and add the filter. Within the function we can set our arguments (the options we'd like to change). In my case I wanted to have the same fontsize no matter how many posts there are with that tag name. This is what I did:

Source code
   
1
2
3
4
56

function widget_custom_tag_cloud($args) {
 
    $args = array(
                'unit'      => 'px',
                'largest'   => 12,                'smallest'  => 12,
        );
 
    return $args;
}add_filter( 'widget_tag_cloud_args', 'widget_custom_tag_cloud' );

Simple put this in your functions.php and you're done. You change many things, for example you can exclude certain tags or change the order. For all the possible arguments check the wordpress codex on this matter.
