Making the size of two fields in comment form the same programmatically in my node comment form I have a 'your name' field and an 'email' field for users to fill out. They are different in length and like them both to be length '30'. How can I do this with hook_form_comment_form_alter?

I've tried this, with no success (in template.php):

$form['field_email']['#size'] = 30;
$form['author']['#size'] = 30;


I've tried just changing the size of the field for the email field in the content type comments manage fields area but it does nothing.
In the core comment form the 'author' element is an array of form elements:

  $form['author']['name']['#size'] = 30;
  $form['author']['mail']['#size'] = 30;
