Sizing textarea field in custom metabox

You could try styling it with CSS by adding an ID or a class to the textarea and inserting styles into the wp_admin head.

Or, a quick way would be to do something like this :

echo '<textarea name="_dresscode" class="widefat" style="width:400px !important; height:80px !important;" >' . $dresscode  . '</textarea>';

If not, have you tried simply :

echo '<textarea name="_dresscode" class="widefat" cols="50" rows="5">' . $dresscode  . '</textarea>'
